SOURCE AREA ISCO EVALUATION CLEBURN STREET WELL SITE GRAND ISLAND, NEBRASKA

1.0 INTRODUCTION

The U.S. Environmental Protection Agency (EPA) Region 7 tasked HydroGeoLogic, Inc. (HGL) to conduct a pilot-scale in situ chemical oxidant injection (ISCO) treatability study (TS) at the Cleburn Street Well Site in Grand Island, Nebraska. Potassium permanganate (KMnO4) was chosen as the chemical oxidant due to its relatively low cost, ease of use, and demonstrated effectiveness in treating dissolved chlorinated volatile organic compound (VOC) contamination at other sites. This work is being executed under Architect and Engineering Services (AES) Contract EP-S7-05-05, Task Order 0041. The TS was performed to evaluate the effectiveness of ISCO in treating dissolved VOC contamination in the source area at the site. Pre-injection concentrations of tetrachloroethene (PCE), the primary contaminant of concern, in the source area groundwater ranged from 100,000 micrograms per liter (µg/L) to 160,000 µg/L. This report details the TS activities, which commenced in December 2009 and included five rounds of post-injection monitoring completed through July 2010. The report is organized as follows:

• Section 1 introduces the objectives of the TS.

• Section 2 provides background information for the site, including a summary of a previous TS conducted within the plume immediately downgradient of the source.

• Section 3 describes how the study was designed, and all field efforts conducted in support of the TS.

• Section 4 presents the results of the post-injection groundwater investigation.

• Section 5 provides recommendations for future use of ISCO at the site.

• Section 6 lists the references cited in the report.

All field activities were conducted in accordance with the procedures specified in the Final Sampling and Analysis Plan for Long-Term Response Action, Cleburn Street Well Site, Grand Island, Nebraska (SAP) dated January 2009 (HGL, 2009) and the SAP Addendum dated November 18, 2009 (HGL, 2009b). Any deviations from the referenced planning documents are discussed in Section 3. The purpose of the ISCO TS in the source area was to evaluate whether ISCO is effective in reducing levels of chlorinated VOCs in groundwater to below maximum contaminant levels (MCLs). Groundwater samples were collected before injections were completed to establish baseline VOC levels. After injection of the ISCO, five rounds of performance monitoring samples were collected to document post-injection contaminant levels in groundwater at the

source area. The findings of the post-injection monitoring will be used to determine whether changes in the chemical oxidant injection approach are needed, if the ISCO remedy is carried through to full scale implementation.

2.0 BACKGROUND

2.1 SITE LOCATION AND DESCRIPTION

The Cleburn Street Well Site (site) is located near the downtown area of Grand Island, and is comprised of various locations in downtown Grand Island where PCE contamination of subsurface soils and groundwater has been identified. The site encompasses a developed area of approximately 144 city blocks (Figure 2.1) and land use consists of single family residences, light manufacturing, and retail shops. A Union Pacific railroad corridor passes through the site from southwest to northeast. The focus of this TS was the source area located on the west side of Eddy Street beneath the former One Hour Martinizing (OHM) building located at the southwest corner of Eddy Street and 4th Street (Figure 2.2).

2.2 PHYSICAL SITE SETTING

2.2.1 Site Soils and Geology

Surficial soils at the site consist of O’Neill and Pivot loams or O’Neill sandy loam characterized by dark grayish-brown, friable, sandy silt or silty sand that extend from the surface to approximately 3 feet below ground surface (bgs). Beneath the surficial soils are Quaternary alluvial sands and gravelly sands occasionally interbedded with thin clayey sand, sandy clay, silt, and silty sand layers. A prominent silt/silty sand unit occurs within the alluvium at a depth that ranges from 24 to 28 feet bgs at the top to 35 to 39 feet bgs at the bottom. This unit appears to be continuous beneath the site. The Quaternary alluvial deposits comprise the shallow aquifer which, in the vicinity of the site, extends to depths ranging from 87 to 94 feet bgs. Underlying the Quaternary alluvial deposits is a clay aquitard ranging from 144 to 153 feet in thickness.

2.2.2 Regional and Site-Specific Hydrogeology

Shallow groundwater underlying Grand Island occurs as an unconfined water table aquifer within the alluvial sands and gravels of the Grand Island Formation. The average depth to water is generally 20 feet bgs. Total thickness of the water table aquifer is about 70 feet within the study area. Hydraulic conductivity values range up to 670 feet per day (ft/day) (WJE, 1993). Pumping tests conducted during the design stage of EW-1 in the sand unit yielded a hydraulic conductivity value of 345 ft/day, which calculates to a linear groundwater velocity of 3.5 ft/day (GeoTrans, 2001). The Grand Island Formation aquifer is used regionally as a water supply source for irrigation and potable water. In the vicinity of the Cleburn Street Well Site plume, all water for private domestic use is supplied by the City of Grand Island. The city's municipal well field is located southeast of the city near the Platte River. The predominant regional groundwater flow direction within the shallow aquifer is to the northeast. Regional horizontal gradients of 4 to 7 feet per mile have been measured in the area (Woodward-Clyde, 1997 and 1998; URSG, 1999). However, an east/southeast flow component was documented by HGL during subsequent field efforts. Groundwater measurements were collected by HGL from the site monitoring well network the week of July

26, 2010, during the quarterly groundwater performance monitoring event. The groundwater extraction and treatment (GET) system had been shut down for approximately 7 months when these measurements were recorded; therefore, water levels were not influenced by pumping of the extraction wells .Water level measurements indicated that groundwater flow in the site area appears split between the regional northeast trend and an east/southeast component (Figure 2.3). It is possible that the intermittent pumping of the dewatering sump at the Eddy Street underpass contribute to this bidirectional flow. Cross sections were developed from the lithologic logging conducted during the installation of the monitoring wells completed in February and March 2009 and are included in the Well Installation and Testing and Evaluation of the Silt Layer, Cleburn Street Well Site (HGL, 2009a). These cross section maps are included as Figures 2.4 and 2.5. Cross sections from the Februaru/March 2009 investigation were compared to the lithology logged in two temporary boreholes in the study area (SB-01 and SB-02) that were advanced and logged before initiating the source area TS. The lithology was consistent with the lithology documented in the February/March 2009 study. The cross sections depict a silt/silty sand unit that occurs at approximately 28 feet to 39 feet bgs at the site. Much of the contamination beneath the site is contained within this silt/silty sand. The silt/silty sand unit then dips slightly to the northeast. The dipping of the silt/silty sand to the northeast combined with the groundwater flow direction appears to be controlling the migration of the PCE, causing it to migrate in a fan-shaped pattern that spans from the northeast to the east.

2.3 SUMMARY OF TREATABILITY STUDY FOR THE GROUNDWATER PLUME (2009)

A TS was conducted from June through August 2009 under Task Order 0019. This TS focused on the plume downgradient of the source on the east side of Eddy Street. The purpose of this TS was to determine whether ISCO injections in the plume would be effective in supplementing the existing GET system operating at the source A full discussion of the study and findings are detailed in the In Situ Chemical Oxidant Injection Evaluation submitted to EPA in November 2009 (HGL, 2009c). A brief review of this TS and the findings of the post-injection monitoring follows. The TS involved application of KMnO4 delivered through 20 injection points in the downgradient plume from the Cleburn Street source area. Three rounds of post injection sampling were conducted at 16 temporary and permanent wells located crossgradient, within, and downgradient of the injection zone. In June 2009, eight temporary monitoring wells were installed cross-gradient and immediately downgradient of the injection zone to supplement the existing monitoring well network and facilitate groundwater performance monitoring during the study (Figure 2.6). Wells were installed in clusters of two to monitor the upper and lower portion of the silt layer as well as the transition to sands at each location as follows:

U.S. EPA Region 7 Source Area ISCO Evaluation 2-3 November 2010

• A-level wells (DPT-1-A, DPT-2-A, DPT-3-A, and DPT-4-A) were screened at 25 to 35 feet bgs to characterize contaminants in the upper sand and sandy silt/silty sand zone near the water table..

• B-level wells (DPT-1-B, DPT-2-B, DPT-3-B, and DPT-4-B) were screened at 35 to 45 feet bgs to characterize the lower sandy silt/silty sand and sand zone.

Injection points were arranged in three rows. The two outside rows consisted of seven injection locations and the middle row had six injection locations. The middle row was staggered between the outside rows. The rows were spaced five feet apart. Injection points within each row were spaced 10 feet apart. The injection sequence commenced at the northeastern corner and proceeded south following the injection point configuration shown in (Figure 2.7). Injections were completed beginning at hydraulically downgradient locations and moving upgradient. The KMnO4 solution was injected into the subsurface using a direct-push technology (DPT) rig to deliver the injectant at the proper interval. At each injection point, the DPT rods were advanced to depth with the DPT rig. The end of the rod was equipped with a 13-inch long injection tool with a series of four holes spaced one inch apart along its length. The injection tool was then exposed and the injectant was dispersed through the holes. Injection generally started at 31 feet bgs and moved upward to 20 feet bgs in one-foot increments (bottom-up injection approach). An average of 658 gallons of KMnO4 solution was injected per location. The total volume of KMnO4 solution injected was 13,154 gallons. Post-injection monitoring was conducted over a 2-month period from late June through late August 2009. Analytical results indicated that KMnO4 was effective in reducing PCE concentrations within the plume and could be used to reduce PCE concentrations at the source area. A final recommendation of the plume study was to focus future KMnO4 injections at the source area where it would have a greater benefit for reducing contamination. Based on the findings of the TS completed in the plume downgradient of the source, EPA determined that although the optimized GET system appeared to be controlling plume migration, it was not effectively remediating contamination in the source area. EPA subsequently tasked HGL to complete a TS in the source area, as recommended in the plume TS report.

U.S. EPA Region 7 Source Area ISCO Evaluation 3-1 November 2010

3.0 STUDY SETUP AND PROCEDURES

The TS activities for the source area ISCO evaluation were conducted from December 2009 through July 2010. The TS focused on a portion of the source area beneath the former OHM building and in the frontage road adjacent and east of the building (Figure 3.1). This area has historically been the most contaminated portion of the site. TS activities included the following:

• Limited characterization of the source area by conducting groundwater profile sampling.

• Installation of permanent injection wells.

• Injection of chemical oxidants into the subsurface.

• Collection of pre- and post-injection groundwater samples from the monitoring wells and injection wells.

The schedule for these activities is displayed in Table 3.1. A discussion and evaluation of the sample results is presented in Section 4.0.

3.1 GROUNDWATER PROFILE SAMPLING

The groundwater profile study was conducted December 3, 4, and 5, 2009. Groundwater samples were collected from temporary DPT wells emplaced at 10 locations (GW-01 through GW-10) in the source area to provide limited characterization of the area and determine optimal placement of permanent injection wells for the TS (Figure 3.1). Five groundwater samples were collected from each location to characterize the water column in and above the silt layer. Samples were collected at 4-foot intervals starting with the deepest interval: 36 to 40 feet bgs; 32 to 36 feet bgs; 28 to 32 feet bgs; 24 to 28 feet bgs; and 20 to 24 feet bgs,. No samples were collected from below 40 feet because previous investigations have identified the bottom of the silt layer, where much of the contamination appears to be bound, is approximately 40 feet bgs. The sampling apparatus was advanced to depth using the track-mounted DPT rig. Then, the 4-foot sampling screen was exposed, and the groundwater sample retrieved through disposable tubing using a foot valve as specified in the SAP Addendum (HGL, 2009b). Two to three casing volumes of water were purged from the tubing, field parameters were collected, and then the sample was collected at each depth interval. Tubing was removed and replaced between sample intervals To facilitate quick turn on the analysis, samples were screened for PCE and trichloroethene (TCE) by Platte Valley Laboratories, Inc. in Gibbon, Nebraska. All samples were collected and handled in accordance with the SAP Addendum (HGL, 2009b). After collection, all samples were labeled, placed in coolers, and iced, for temporary storage pending hand delivery to Platte Valley Laboratories.

The data was received within two days and reviewed by the field team. Figure 3.1 displays the PCE concentrations by depth. In general, PCE levels increased from west to east. Levels also were higher in the shallower intervals. In GW-10, the westernmost borehole, the highest PCE concentration was 11 µg/L in the 20 to 24 foot bgs interval. In GW-09, on the eastern portion of the study area, PCE was identified at 99,241 µg/L in the 20 to 24 foot bgs interval. TCE was detected in the five easternmost boreholes (GW-05 through GW-09) at much lower concentrations. The highest detection of TCE was identified in GW-07 at 184 µg/L in the 20 to 24 foot bgs interval. The screening data is included in Appendix A. After the sampling activities were completed, the casing and screens were withdrawn from the subsurface, the boreholes were backfilled with granular bentonite, and the surface condition at the well site restored.

3.2 PERMANENT INJECTION WELL INSTALLATION

Based on the data obtained from the groundwater profile sampling, ten locations were chosen to install the injection wells. The locations were adjusted as necessary to accommodate physical access limitations within the building (Figure 3.2). The wells were installed during the same field event as the groundwater profile investigation using the same subcontractor: GSI. The ten injection wells were constructed with 10-foot screens for delivery of the KMnO4. The screen interval for the ten injection wells extends from 22 feet bgs to 32 feet bgs for injection into the most contaminated interval in the subsurface as documented in the groundwater profile study. All of the injection wells were constructed using 2-inch schedule 40 polyvinyl chloride (PVC) casing and ten feet of PVC 0.010-inch milled slot screen. Wells were completed using a silica sand filter pack, a chip bentonite seal, and 28 percent solids bentonite slurry pressure-grouted using a tremmie pipe from the top of the bentonite seal to ground surface. All of the injection wells were finished at the surface with flush mount completion in concrete that matched the surrounding concrete floor of the facility. Appendix B includes Boring Logs for the new wells; Appendix C contains the Monitoring Well Construction Diagrams; and Appendix D includes the Nebraska Well Registration Forms. Well installation procedures were conducted in accordance with the SAP Addendum (HGL, 2009a).

3.3 CHEMICAL OXIDANT INJECTION ACTIVITIES

Two injection rounds were completed: one in December 2009 and the second in March 2010. KMnO4 was delivered through 14 permanent injection wells in the Cleburn Street source area: the 10 newly installed wells and four existing wells that are screened across the silt zone. Concentrated KMnO4 powder was shipped to the site in 5-gallon buckets (55.1 pounds of KMnO4 in each) by the Carus Chemical Company and stored in the secured remediation building. Water was provided by the city from a hydrant located at the transportation facility on the corner of West North Front Street and North Washington Street. To achieve a 2.0 percent KMnO4 mixture, approximately 16.7 pounds of KMnO4 powder was mixed with every 100

gallons of water in a mixing tank. Tables 3.2 and Table 3.3 summarize the injection and chemical oxidant parameters. The concentration of KMnO4 was based on soil testing conducted during the TS completed in the plume. It was determined from boring logs that soils beneath the building were similar to those encountered during this previous study. A key test to determine the percentage of KMnO4 required is based on the natural oxidant demand of the soil, which reflects the amount of KMnO4 that will be consumed by natural reducing agents during a given amount of time. The soil samples that had been tested for the plume TS had a 48-hour KMnO4 demand value of 0.4 grams per kilogram (g/kg). Natural oxidant demand of less than 10 g/kg at 48 hours is considered favorable for in situ chemical oxidation with KMnO4. GSI used two high density polyethylene tanks sized at 1,320 gallons and 500 gallons, to mix and store the KMnO4 solution. The two tanks were utilized so that while one tank was supplying KMnO4 to the injection wells, the other tank could be used to mix and prepare the solution to minimize delays. The tanks were filled with water from the city’s transportation department and transported back to the site. The solution was circulated in the tanks with a pump to keep the KMnO4 powder in solution. The equipment used by GSI is shown in Appendix D – Photographic Documentation. Pumps and fittings were provided with secondary containment. A neutralizing solution consisting of one part vinegar, one part hydrogen peroxide, and one part water was used to clean up equipment and neutralize KMnO4 spills. A 1½-inch rubber hose was used to connect the tanks to the injection header. Chemical oxidant was pumped from the tanks through a flexible hose to the injection header. The injection header was configured for four injection points. The injection header consisted of a gate valve, flow meter, and pressure gauge for each injection point. The pressure and flow rate to each injection point could be controlled by the injection header. Injection points (IW-1 through IW-10) were spaced approximately 10 feet apart (Figure 3.2). In addition, four existing wells (DPE-1 through DPE-4) supplemented the injection wells to target the silt zone. The four DPE wells are six inches in diameter and screened from approximately 31 to 36 feet bgs. They are spaced about 15 feet apart. The flow rate, total volume injected, and pressure were monitored throughout the injection process to determine the maximum rate at which oxidant could be delivered to the targeted zone. Nebraska regulations require that the pressure not exceed approximately 1 pound per square inch (psi) per foot of overburden. In general, KMnO4 could be delivered between 5 and 10 gallons per minute (gpm) to each well without exceeding the pressure requirements. The total volume of KMnO4 solution injected based on flow measurements was 34,500 gallons. Approximately 2,750 gallons were delivered to each of the 10 injection wells and 1,750 gallons were delivered to each of the four DPE wells as planned. Injection pressures were at or below the 1 psi/ft of overburden requirement.

3.4 GROUNDWATER MONITORING PROGRAM

The monitoring program for the KMnO4 injections at the Cleburn Street Well Site consisted of five separate monitoring events conducted over a 6-month period. Two monitoring events occurred after the December 2009 injection: January and March 2010. Three monitoring events occurred after the March 2010 injection: April, May, and July 2010. Groundwater samples were collected from permanent wells within the injection area. Downgradient wells on the east side of Eddy Street were sampled during the quarterly monitoring (scoped under a separate task). The location of each groundwater sampling point for the TS is shown on Figure 4.1. Samples were collected from the same wells for all five post-injection monitoring events. Groundwater samples were collected for VOCs and total metals analyses. VOC groundwater samples were analyzed using SW-846 Methods 5030B, and 8260B, EPA Method 624 and EPA Region 7 Standard Operating Procedure (SOP) 3280.13C. Metals were analyzed in accordance with EPA Method 200.7. VOC groundwater samples were collected in 40-milliliter (ml) vials. Ascorbic acid was added to remove the color interference from the KMnO4. Total metal samples were collected in 1-liter polyethylene containers and preserved with nitric acid to a pH of <2. The samples were analyzed by the EPA Region 7 laboratory. The target analytes for pre-injection and post-injection monitoring were arsenic, chromium, manganese, PCE, TCE, cis-1,2-dichloroethene (cis-1,2-DCE), and trans-1,2-dichloroethene (trans-1,2-DCE). Other analytes detected were noted as they pertained to quality assurance/quality control (QA/QC) and the overall analysis of the effectiveness of the KMnO4 injection.

4.0 GROUNDWATER MONITORING AND EVALUATION

A pre-injection baseline monitoring event was conducted in December 2009 to establish pre-injection contaminant concentrations within and downgradient of the injection area. The first KMnO4 injection was conducted from December 16 through December 22, 2009, followed by groundwater monitoring events at 4 weeks and 10 weeks. The second KMnO4 injection was conducted from March 8 through March 11 followed by groundwater monitoring events at 4 weeks, 8 weeks, and 20 weeks after oxidant injection. Other than the baseline monitoring event, groundwater samples were collected from 20 monitoring wells located within and downgradient of the injection zone in accordance with procedures described in the SAP Addendum (HGL, 2009b). The four DPE injection wells were not sampled for the baseline sampling event. The wells sampled for the TS cover multiple depth intervals as follows:

• 17 feet to 32 feet bgs – MW-2A and MW-12A • 19 feet to 29 feet bgs – ERT-14, ERT-15, and ERT-16 • 22 feet to 32 feet bgs – IW-1 through IW-10 (Both IWs and MWs) • 31 feet to 36 feet bgs – DPE-1, DPE-2, DPE-3, and DPE-4 (Both IWs and MWs) • 79 feet to 89 feet bgs – MW-2B

The well locations are shown on Figure 4.1.

4.1 IDENTIFICATION OF WELLS AFFECTED BY OXIDANT

Because KMnO4 is readily identifiable in groundwater samples by its pink-to-purple tint, visual inspection of the samples usually proves to be an excellent indicator along with the presence of specific metals. The discussion in this section focuses on the wells (other than injection wells) known to be affected by KMnO4. Based on the purple coloration and analytical data indicating elevated levels of manganese (found in KMnO4), the following wells were identified as locations affected by the KMnO4 injections:

• MW-2A • ERT-15 • ERT-16

Metals were analyzed in groundwater to gauge the effect the KMnO4 had on the aquifer materials (whether metals were mobilized as a result of injection), and what effect metal impurities contained in the KMnO4 injectant had on groundwater quality. The discussion below focuses on manganese, which is associated with KMnO4, and metals considered toxic (arsenic, chromium, and cadmium). Metals analytical data is presented in Table 4.1. Analytical reports are included in Appendix E.

HGL—Source Area ISCO Evaluation, Cleburn Street Well Site—Grand Island, NE

U.S. EPA Region 7 Source Area ISCO Evaluation 4-2 November 2010

Arsenic was not detected above the reporting limit of 25 µg/L (MCL for arsenic is 10 µg/L) in pre-injection (baseline) samples. During the entire post-injection monitoring period, arsenic was not detected at a concentration above the reporting limit, though the reporting limit ranged from 25 µg/L to 25,000 µg/L in the post-injection monitoring period. Reporting limits increased for all of the metals results due to elevated manganese concentrations from the injected KMnO4.

Arsenic

Chromium was detected in the pre-injection (baseline) sample from ERT-15 at 16 µg/L. This is below the MCL of 100 µg/L for total chromium.

Chromium

For the post-injection monitoring, chromium was detected in samples collected from all three monitoring wells affected by KMnO4. The general trend for these wells was for chromium concentrations to increase through the March post-injection sampling, then gradually decrease in the April, May, and July events. In ERT-15, total chromium peaked at 177 µg/L in March 2010 and decreased to 51 µg/L in May 2010. In ERT-16, total chromium peaked at 11,000 µg/L in March and decreased to 4,030 µg/L in May. In MW-2A, total chromium peaked at 14,500 µg/L in March and decreased to 4,030 µg/L in July 2010. In both ERT-16 and MW-2A, the levels still exceed the MCL and will need to be monitored in subsequent quarterly sampling events. An increase in chromium followed by a decrease is expected in wells influenced by KMnO4

injectant, due to precipitation of metals and mixing with groundwater not affected by KMnO4.

A high concentration of manganese is an indication that a well was directly affected by the KMnO4 injections. Very high concentrations of manganese were identified in MW-2A, ERT-16 and ERT-15. As a component of the injected KMnO4, the levels increased the most in January and April 2010, the first monitoring event after each injection. In MW-2A and ERT-15, the concentration increased from baseline levels of less than 10 µg/L for both wells to 417,000 µg/L in MW-2A and 325,000 µg/L in ERT-15 in April. There is no MCL for manganese. It is anticipated that high manganese concentrations will continue to decrease in the immediate area of the KMnO4 injections.

Manganese

Much lower levels of manganese were identified in MW-12A, ERT-14, and MW-2B. Only MW-2B appears to have been impacted by the KMnO4 injections. The manganese concentration rose from 5U in the baseline sample to 71 µg/L in March 2010. It has continued to drop in subsequent sampling events.

It should also be noted that cadmium was detected in IW-08 in the July 2010 sampling event. Data indicate it was detected at 3,860 µg/L, which is significantly above the MCL of 5 µg/L. However the duplicate sample for this event did not have a detection for cadmium (3,000 U). In addition, cadmium has not been detected in IW-08 or any of the other monitoring well locations throughout the post-injection monitoring period. Continued monitoring should be conducted for

cadmium to verify that this result is anamolous.

4.2 VOLATILE ORGANIC COMPOUNDS

For the VOC discussion, the 20 injection and monitoring wells sampled for the post-injection performance monitoring will be referred to collectively as monitoring wells. VOC results will be evaluated in all of the monitoring wells. VOCs of interest detected in groundwater samples from the MWs include PCE, and the degradation products TCE and cis-1,2-DCE. Other degradation products of TCE such as trans-1,2-DCE and vinyl chloride were not detected in groundwater samples. Carbon tetrachloride and its degradation product chloroform also were identified in several of the groundwater samples. The six analytical data packages for the entire study from December 2009 through July 2010 are included in Appendix E.

PCE was detected in all 16 of the wells sampled wells during the baseline event; however, levels were significantly variable from 5.2 µg/L in IW-01 on the western portion of the injection area to 140,000 µg/L in IW-09, approximately 40 feet to the northeast (Figure 4.2). The baseline data show that PCE concentrations generally increase from the southwest portion of the injection area to the northeast.

PCE

After the injections, PCE concentrations decreased in most of the wells impacted by KMnO4. In the first post-injection monitoring event in January 2010, many of the samples dropped to below the PCE reporting limit of 5 µg/L, although PCE was detected in six of the 20 samples at levels ranging from 11 µg/L in ERT-14 to 3,900 J in MW-2A (Figure 4.3). PCE concentrations remained much lower than the baseline data in the monitoring wells after the second injection event, but levels began to increase in the July 2010 sampling event. This was likely due to both the KMnO4 being consumed and dilution as it mixed with groundwater in the months after the final injection. The number of wells with detections of PCE rose from six in January to twelve in July. Concentrations ranged from 20 µg/L to 7,500 µg/L (Figure 4.4). In general, the PCE concentrations remained well below the baseline concentrations displayed on Figure 4.2. PCE concentrations in MW-2A are representative of the trend that occurred in the wells impacted by the KMnO4. Figure 4.5 displays the drop in PCE concentration in MW-2A after the first and second injections and the slow rise in PCE that began 4 months after the last injection. PCE concentrations in MW-12A are indicative of a cross-gradient monitoring well not impacted by the KMnO4. It is likely that PCE concentrations began to rise in MW-12A because contamination was pushed horizontally outward from the injection zone. The trend graph in Figure 4.6 shows PCE increases after each injection event, followed by a drop as natural easterly groundwater flow resumes when not influenced by injection pressure.

TCE was detected in five monitoring wells (IW-7 through IW-10, MW-2A) in the baseline event at levels ranging from 12 µg/L to 40 µg/L; all of which were above the MCL of 5 µg/L, but still significantly lower than the PCE concentrations in groundwater. TCE was not detected in any of

TCE

the wells affected by KMnO4. Of the wells not affected by KMnO4, only MW-12A contained TCE. The TCE levels fluctuated from 150 µg/L to 370 µg/L in MW-12A during the course of the TS. Similar to PCE, it appears that the TCE levels in this well may have increased as a result of the injections (Figure 4.7).

All detections of cis-1,2-DCE (a degradation product of TCE) were in samples from MW-12A, a MW that was not impacted by the source area injections. The cis-1,2-DCE was present in the baseline sampling event at 23 µg/L and fluctuated between 5.0 U and 22 µg/L in the post-injection events. All of the results were below the MCL for cis-1,2-DCE of 70 µg/L.

Cis-1,2-DCE

Carbon tetrachloride (CCl4) was not detected in any of the monitoring wells sampled during the baseline event. In the first post-injection sampling in January 2010, 12 of the 20 MWs had detections of CCl4 ranging from 21 µg/L in IW-08 to 1,200 µg/L in MW-2A. These detections are above the MCL for CCl4 of 5 µg/L. Based on this information, it appears the KMnO4 injections mobilized CCl4 that was bound in the silty material. In general, CCl4 concentrations peaked in the April 2010 post-injection sampling event, then began to trend downward. However, in the final sampling event in July 2010, 10 wells still had detections that exceeded the MCL, with concentrations ranging from 40 µg/L in IW-05 to 1,200 µg/L in ERT-16.

Carbon Tetrachloride

Chloroform, a degradation product of CCl4, was not detected in the monitoring wells sampled during the baseline event, but was detected after the two injection events. As with CCl4, chloroform was likely mobilized from the soil matrix by the KMnO4 injections. Chloroform was identified in 11 of the 20 wells sampled with detections ranging from 6 µg/L to 510 µg/L. There is no established MCL for chloroform but the MCL for total trihalomethanes, which includes chloroform, is 80 µg/L. In the final sampling event for the study in July 2010, 9 of the 20 wells had detections of chloroform and 8 of those detections were above 80 µg/L.

Chloroform

CCl4 and chloroform have not been identified in any of the downgradient monitoring wells sampled for the quarterly sitewide sampling.

5.0 SUMMARY AND RECOMMENDATIONS

5.1 SUMMARY

This source area TS involved application of 2 percent KMnO4 delivered through 14 permanent injection wells in the Cleburn Street source area. A limited groundwater profile study was conducted in December 2009 to determine the placement of ten of the injection wells. Four of the injection wells were existing wells that were screened across the silt zone. Two injections were performed: one in December 2009 and the second in March 2010. Five rounds of post-injection sampling were conducted with two sampling rounds after the first injection and three sampling rounds after the second injection. Based on the results of the groundwater profile study, the injection screen interval for the 10 permanent wells was set from 22 feet bgs to 32 feet bgs to target the highest levels of PCE in the saturated sands and upper portion of the silt layer. The four existing wells used for injection are screened from 31 to 36 feet bgs within the silt zone and located approximately 20 feet downgradient and east of the newly installed injection wells. For each injection event, 34,500 gallons of 2 percent KMnO4 were delivered through the14 permanent wells. A review of the data through July 2010 from the 20 wells sampled for post-injection performance monitoring indicates that the KMnO4 injections resulted in reduction of PCE in groundwater. Water quality parameters did not show any permanent affect on groundwater quality; noted effects were short-lived and dissipated as the KMnO4 was consumed. In addition, quarterly sampling of wells downgradient of the source (conducted under a separate subtask), showed no noticeable increases or decreases in PCE concentrations. It does appear that the KMnO4 injections have caused a release of CCl4 and chloroform from the injection interval. Before the TS and in the baseline groundwater sampling event, CCl4 and chloroform were not considered a contaminant of interest. It is not clear if these two chemicals originated at the site or if they migrated from an upgradient location and became bound in silt. Since 2006, CCl4 has been detected only one time in 16 quarterly sampling events of the entire monitoring well network. It was detected at 1.4 µg/L in MW-2A, below the MCL of 5 µg/L.

5.2 RECOMMENDATIONS

KMnO4 was effective in reducing PCE concentrations in the source area and could be used in a full-scale approach to reduce PCE concentrations. Groundwater profile data indicate that PCE contamination in groundwater both increased in concentration and migrated vertically from western portion of the study area to the eastern portion of the study area. It appears that the upgradient boundary has been delineated on the southwest portion of the injection zone. However, additional characterization (including subsurface soil and groundwater sampling) is needed to the north, west, and northwest of the source area injection zone to fully characterize the nature and extent of the subsurface contamination. This information is also required to inform the design of full-scale implementation of the potential ISCO remedy.

Once full characterization is completed, injection in the source area should follow an outside-in/downgradient-upgradient injection pattern where injections are first conducted at the downgradient outer edges of the groundwater plume. This reduces the likelihood of contaminants being pushed outward horizontally, as occurred during the TS. Injection of KMnO4 should focus on the poorly graded sand portion of the aquifer and the upper fringe of the sandy silt/silty sand where much of the contamination appears to reside beneath the building. Injection directly into the low permeability sandy silt/silty sand layer is problematic, as it will be difficult to achieve even distribution of KMnO4. If additional characterization sampling indicates that the sandy silt/silty sand layer beneath the building is highly contaminated, the injection design may include an option to inject directly into this layer using low pressure over a longer injection period. This approach may be effective in reducing the likelihood of creating preferential pathways, and prevent upwelling of chemical into the building through injection and monitoring wells. Because CCl4 and chloroform were identified at levels above the MCL after injection activities, additional remediation alternatives may be needed to supplement (or replace) full-scale implementation of KMnO4, because KMnO4 is not effective in treating CCl4 and chloroform. The Remedial Investigation/Feasibility Study that is under way at the Cleburn Street Well Site will provide recommendations for the remediation of these contaminants. One alternative may be to utilize the existing groundwater extraction and treatment system in combination with the KMnO4 injections to remediate subsurface contamination. In the near term, additional monitoring is needed to evaluate the levels and migration of CCl4 and chloroform.

Dilutions were necessary in order to obtain valid results due to matrix interferences. Thereporting limits were elevated (X times) due to dilutions in samples 1-11(1000), 4FD &10FD(1000), 12(10), 13(100), 14(10), 15(10), 16-19(1000), 18FD(1000), and 45(1000).

Slight nickel (20.2) contamination was found in the laboratory method blank, 951MB. Onlysamples containing this analyte at a level greater than ten times the contamination level ofthe blank are reported without being qualified. All samples that contained this analyte butat a level less than ten times the contamination in the blank have the result U-codedindicating that the reporting limit has been raised to the level found in the sample.Samples affected were: 20FB.

Aluminum (72, 76-127), beryllium (69, 77-105), cadmium (68, 77-105), cobalt (68, 70-102), copper (72, 79-105), sodium (75, 84-109), iron (74, 76-109), magnesium (73, 85-108), potassium (69, 85-112), titanium (71, 78-112), and vanadium (69, 76-105) wereUJ-coded in sample 12. These analytes were not found in the sample at or above thereporting limit; however, the reporting limit is an estimate (UJ-coded) due to low recoveryof these analytes in the laboratory matrix spike duplicate. The actual reporting limit forthese analytes may be higher than the reported value.

Barium (56, 70-114) and calcium (45, 81-110) were J-coded in sample 12. Although theanalytes in question have been positively identified in the sample, the quantitation is anestimate (J-coded) due to low recovery of these analytes in the laboratory matrix spikeduplicate. The actual concentration for these analytes may be higher than the reportedvalue.

Nickel (64, 70-102) was J-coded in sample 15. Although the analyte in question has beenpositively identified in the sample, the quantitation is an estimate (J-coded) due to lowrecovery of this analyte in the laboratory matrix spike. The actual concentration for thisanalyte may be higher than the reported value.

These analyteswere not found in the sample at or above the reporting limit, however, the reporting limit isan estimate (UJ-coded) due to poor precision obtained for these analytes in the laboratorymatrix spike and matrix spike duplicate. The actual reporting limit for these analytes maybe higher than the reported value.

Barium (32, 5.0) and calcium (31, 5.0) were J-coded in sample 12. Although the analytesin question have been positively identified in the sample, the quantitation is an estimate (J-coded) due to poor precision obtained for these analytes in the laboratory matrix spike andmatrix spike duplicate.

Copper (5.5, 5.0), thallium (18, 5.2), and zinc (7.4, 5.0) were UJ-coded in sample 15.These analytes were not found in the sample at or above the reporting limit, however, thereporting limit is an estimate (UJ-coded) due to poor precision obtained for these analytesin the laboratory matrix spike and matrix spike duplicate. The actual reporting limit forthese analytes may be higher than the reported value.

Nickel (24, 5.0) was J-coded in sample 15. Although the analyte in question has beenpositively identified in the sample, the quantitation is an estimate (J-coded) due to poorprecision obtained for this analyte in the laboratory matrix spike and matrix spikeduplicate.

(N/A)

Reporting Limits:Twenty-two of the samples contained potassium permanganate. These samples werediluted to keep the column from being damaged. The resulting reporting limit for thesesamples were 5000 times higher than the normal reporting limit. Acetone (+20.7%) was UJ-coded in samples 32, 20-FB, 68-FB, 69-FB, 70-FB, 12, 14, 21,21-FD, 23, 24, 25, 26, 27, 28, and 29. This analyte was not found in the samples at orabove the reporting limit, however, the reporting limit is an estimate (UJ-coded) due to thecontinuing calibration check not meeting accuracy specifications. The actual reporting limitfor this analyte may be higher than the reported value. Styrene (68% & 64%, 83%-121%) was UJ-coded in sample 41. This analyte was notfound in the sample at or above the reporting limit, however, the reporting limit is anestimate (UJ-coded) due to low recovery of this analyte in the laboratory matrix spike. Theactual reporting limit for this analyte may be higher than the reported value. Carbon Disulfide (20RPD, 15PCL) was UJ-coded in sample 32. This analyte was not foundin the sample at or above the reporting limit, however, the reporting limit is an estimate(UJ-coded) due to poor precision obtained for this analyte in the laboratory matrix spikeand matrix spike duplicate. The actual reporting limit for this analyte may be higher thanthe reported value.

EPA Region 7 RLAB Method 3230.1FMethod:

Analyst Notes:100-series had 1.5g Ascorbic Acid in VOA vial added at time of sample collection in thefield.200-series had 1.5g Ascorbic Acid in VOA vial added at time of sample arrival in the lab. Samples 205-208, 210-213, and 217-219 were preserved 1 day after collection.Samples 201-203, 209, and 214-216 were preserved 2 days after collection.Sample 220 was preserved 4 days after collection.Sample 204 was preserved 9 days after collection. Sample 204 data was similar to 104,and was not qualified due to late preservation/analysis. (Samples 204 and 209 weremistakenly stored in a separate area.) All samples were injected within 14 days of collection.pH of preserved samples was ~ 4 or less.

100 series samples appeared clear, except for 101, which was dark purple. Ascorbic acidwas added to sample 101 on arrival into the lab (2 days after collection). 200 series samples appeared dark purple (estimate range 0.015 - 1.5% KMnO4 by eye),except for samples 201, 212, 214, and 215 which were clear.

Note tentatively identified compound at 40ug/L or more, and others, in samples: 101, 103,110, 111, 201, 203, 210, and 211.

Acetone was J-coded in samples 106, 107, 206, 207, and 113. Although the analyte inquestion has been positively identified in the samples, the quantitation is an estimate (J-coded) due to the continuing calibration check not meeting accuracy specifications. Theactual concentration for this analyte may be higher than the reported value.

Acetone was UJ-coded in samples 112. This analyte was not found in the samples at orabove the reporting limit, however, the reporting limit is an estimate (UJ-coded) due to thecontinuing calibration check not meeting accuracy specifications. The actual reporting limitfor this analyte may be higher than the reported value.

Slight Acetone contamination was found in the laboratory method blank. Only samplescontaining this analyte at a level greater than ten times the contamination level of theblank are reported without being qualified. All samples that contained this analyte but at alevel less than ten times the contamination in the blank have the result U-coded indicatingthat the reporting limit has been raised to the level found in the sample. Samples affected

were: 116 and 216.

2-Butanone and Carbon Tetrachloride were J-coded in sample 202. Although the analytein question has been positively identified in the sample, the quantitation is an estimate (J-coded) due to high recovery of this analyte in the laboratory matrix spike. The actualconcentration for this analyte may be lower than the reported value.

Nickel (102, 85-101) was J-coded in samples 17, 17FD, 20, and 19. Although the analytein question has been positively identified in the samples, the quantitation is an estimate (J-coded) due to high recovery of this analyte in the laboratory control sample, 951LCS. Theactual concentration for this analyte may be lower than the reported value.

MS/MSD analysis was performed on samples 4818-1, 4818-9, 4818-10, & 4818-16 (due tomultiple sample shipments). The MS and/or MSD recoveries for sample 4818-1 (82% /74%), 4818-9 (11% / 5%), & 4818-10 (67% / 59%) were below the lower control limit of80%. Calculated RPD's and all LCS recoveries were within applicable control limits.TOCwas J-coded in samples 4818-1, 4818-9, & 4818-10. Although the analyte in question hasbeen positively identified in the samples, the quantitation is an estimate (J-coded) due tolow recovery of this analyte in the laboratory matrix spike. The actual concentration forthis analyte may be higher than the reported value.

A laboratory duplicate (LD) analysis was performed on sample 4818-10. The calculated %difference of 43% between 4818-10 & 4818-10LD was outside the control limit of 20%.TOC was J-coded in sample 4818-10. Although the analyte in question has been positivelyidentified in the sample, the quantitation is an estimate (J-coded) due to poor precisionobtained for this analyte in the laboratory duplicate sample.

Region 7 ESAT Contract Lab (In-House)Lab:

EPA Region 7 RLAB Method 3230.1FMethod:

Nineteen of the samples contained potassium permanganate. These samples were dilutedto keep the column from being damaged. The resulting reporting limit for these sampleswas higher than the normal reporting limit. Dichlorodifluoromethane (+25.5%) was UJ-coded in samples 26-FB, 27-FB, 28-FB, 29-FB,16, 20, 19, 1, 2, 2-FD, 4, 5, 6, 7, 8, 9, and 10. This analyte was not found in the samplesat or above the reporting limit, however, the reporting limit is an estimate (UJ-coded) dueto the continuing calibration check not meeting accuracy specifications. The actualreporting limit for this analyte may be higher than the reported value. Styrene was reported with a N/A and a R-code since it was not recovered in the matrixspike or duplicate. The potassium permanganate in the diluted sample is probably whyStyrene did not recover. Styrene had unacceptable response in the laboratory matrix spikeindicating that it was not possible to obtain valid results for this analyte. Results of 'N/A'were reported with a R-code for samples 1. trans-1,2-Dichloroethene (3% & 2%, 82%-121%), cis-1,3-Dichloropropene (17% & 15%,82%-113%), trans-1,3-Dichloropropene (2% & 1%, 84%-117%), and Vinyl Chloride (12%& 10%, 77%-120%) were UJ coded in sample 1. These analytes were not found in thesample at or above the reporting limit, however, the reporting limit is an estimate (UJ-coded) due to low recovery of these analytes in the laboratory matrix spike. The actualreporting limit for these analytes may be higher than the reported value. The low recoveryis probably due to the potassium permanganate that was present in the diluted sample. trans-1,2-Dichloroethene (33RPD, 10PCL), cis-1,3-Dichloropropene (15RPD, 7.8PCL),trans-1,3-Dichloropropene (35RPD, 8.5PCL), Methyl tert-butyl ether (6.2RPD, 5..4PCL), andVinyl Chloride (20RPD, 13PCL) were UJ-coded in sample 1. These analytes were not foundin the sample at or above the reporting limit, however, the reporting limit is an estimate(UJ-coded) due to poor precision obtained for these analytes in the laboratory matrix spikeand matrix spike duplicate. The actual reporting limit for these analytes may be higherthan the reported value.

Dilutions were necessary in order to obtain valid results and to avoid instrumentdamage due to matrix interferences for samples 2, 4, 5, 5 FD, 6, 7, 8, 9, 10, 11, 12, 12 FD,14, 15, 19, 20, 21 , and 22. This increased the reporting limits by a factor of 10000 forthese samples.

Sulfate (134, 80-120) was J-coded in sample 18. Although the analyte in question hasbeen positively identified in the sample, the quantitation is an estimate (J-coded) due tohigh recovery of this analyte in the laboratory matrix spike duplicate. The actualconcentration for this analyte may be lower than the reported value.

Dilutions were necessary in order to obtain valid results due to matrix interferences forsamples 2-15 and 19-22. This increased the reporting limits by a factor of 100 for thesesamples.

Dilutions were necessary in order to obtain valid results due to matrix interferences forsamples 2-15 and 19-22. This increased the reporting limits by a factor of 100 for thesesamples.

Total Dissolved Solids was J-coded in sample 17. Although the analyte in question hasbeen positively identified in the sample, the quantitation is an estimate (J-coded) due tolow recovery of this analyte in the laboratory matrix spike. The actual concentration forthis analyte may be higher than the reported value. (MS/MSD recoveries 82% & 83%, LAL90%)

Samples 4846-18 thru 4846-22 were shipped on 04/09/10 for arrival at the lab on04/10/10. Samples were not delivered until 04/12/10 which resulted in the coolertemperature being 8.4ºC at sample receipt by the laboratory. No data were qualified andthe analysis proceeded as requested.

Total Organic Carbon was J-coded in sample 4846-1. Although the analyte in question hasbeen positively identified in the sample, the quantitation is an estimate (J-coded) due tolow recovery of this analyte in the laboratory matrix spike.

EPA Region 7 RLAB Method 3230.1FMethod:

Total Organic Carbon was J-coded in sample 4846-1. Although the analyte in question hasbeen positively identified in the sample, the quantitation is an estimate (J-coded) due topoor precision obtained for this analyte in the laboratory duplicate sample.

Samples required dilution for high permanganate levels (purple color). Diluted sampleshad raised reporting limits. Samples were diluted as follows: 1: 50x2-14: 4000x15: 2000x16-18: no dilution19-22: 4000x26FB-29FB: no dilution

The dark purple color in the samples prevented the determination of pH, so preservationcould not be confirmed in the following samples: 2, 4, 5, 5FD, 6-12, 12FD, 14, 15, and 19-22. As these samples were analyzed within 7 days of collection no data were affected.

Sample 18 had Trichloroethene and Tetrachloroethene above the calibration range. Thesevalues have been J-coded, as dilutions could not be analyzed due to instrument problems.The value for Trichloroethene should be close to the true value, as it did not exceed thepredicted linear range of the curve (value: 290, Curve upper range: 200ug/L).Tetrachloroethene will be biased lower than the true value.

Dichlorodifluoromethane, Carbon Tetrachloride and Bromoform were UJ-coded in samples1, 2, 4, 5, 5FD, 6-11, 26FB, 27FB, 28FB and 29FB. These analytes were not found in thesamples at or above the reporting limit, however, the reporting limit is an estimate (UJ-coded) due to the continuing calibration check not meeting accuracy specifications, and lowrecovery in the laboratory control sample for Carbon Tetrachloride and Bromoform. Theactual reporting limit for these analytes may be higher than the reported value. Sample 1was also UJ-coded for Bromoform due to low recovery in the matrix spikes.

Dibromochloromethane was UJ-coded in samples 1, 2, 4, 5, 5FD, 6-11, 26FB, 27FB, 28FBand 29FB. This analyte was not found in the samples at or above the reporting limit,however, the reporting limit is an estimate (UJ-coded) due to low recovery of this analytein the laboratory control sample. The actual reporting limit for this analyte may be higherthan the reported value. Sample 1 was also UJ-coded for this analyte due to low recoveryin the matrix spikes.

Dichloroethene, cis-1,3-Dichloropropene, trans-1,3-Dichloropropene, Methylene Chloride,Styrene, and Vinyl Chloride were UJ-coded in sample 1. These analytes were not found inthe sample at or above the reporting limit, however, the reporting limit is an estimate (UJ-coded) due to low recovery of these analytes in the laboratory matrix spikes. The actualreporting limit for these analytes may be higher than the reported value. Trans-1,2-Dichloroethene, trans-1,3-Dichloropropene and Vinyl Chloride were also UJ-coded due topoor precision in the matrix spike and spike duplicate.

Bromomethane, Chloroethane, 1,3-Dichlorobenzene, and Methylene Chloride were UJ-coded in sample 16. These analytes were not found in the sample at or above thereporting limit, however, the reporting limit is an estimate (UJ-coded) due to low recoveryof these analytes in the laboratory matrix spike. The actual reporting limit for theseanalytes may be higher than the reported value.

Low recovery of Matrix Spikes in sample 1 may have been due to permanganate presencein the sample.

for the coded analytes are estimates and the actual reporting limits may be higher.

For the sake of brevity, it can be assumed that all codes not mentioned below are relatedto the permanganate interference, and no further explanatory comments will be posted inthe analysis report. Non-coded data meet all quality control requirements.

Samples 102-114 were diluted to reduce interference from precipitate in the sample vials.They have been reported at a dilution of 2x with a raised reporting limit .

Samples 107 and 110 required a 10x dilution for Carbon Tetrachloride.

Sample 109 was over the calibration range for Carbon Tetrachloride and Chloroform.Sample could not be rerun due to instrument issues. The values reported have been J-coded as they are estimates and may be biased low.

Acid preservation was buffered by the addition of Ascorbic acid. All samples were betweena pH of 2 and 4. The presence of the Ascorbic Acid has been shown to preserve theanalytes in the samples, as the presence of Permanganate, which was neutralized, wouldhave degraded the analytes of interest much more severely than the passage of time.

Samples 102, 104, 105, 105FD, 106-110 were analyzed past the 14-day holding times.This was not used to qualify data, as samples were within 4-14.5 hrs of the holding times.102 - 6.5hrs late104 - 4105 - 14105FD - 14.5106 - 14107 - 13.5108 - 12.5109 - 10110 - 8

Methylene Chloride was UJ-coded in samples 101, 126FB and 129FB. This analyte was notfound in the samples at or above the reporting limit, however, the reporting limit is anestimate (UJ-coded) due to low recovery of this analyte in the laboratory control sample.The actual reporting limit for this analyte may be higher than the reported value.

Sulfate (78, 80-120) was J-coded in sample 17. Although the analyte in question hasbeen positively identified in the sample, the quantitation is an estimate (J-coded) due tolow recovery of this analyte in the laboratory matrix spike. The actual concentration forthis analyte may be higher than the reported value.

Twenty of the samples contained potassium permanganate. These samples were diluted tokeep the column from being damaged. The resulting reporting limit for these samples washigher than the normal reporting limit. Dichlorodifluoromethane (+23.5%) was UJ-coded in samples 52-FB, 53-FB, 54-FB, 24-FB,39, 34, 35, 36, 37, 38, 40, 40-FD, 42, 43, 44, 45, 46, 47, 26, 27, 28, 29, and 29-FD. Thisanalyte was not found in the samples at or above the reporting limit, however, thereporting limit is an estimate (UJ-coded) due to the continuing calibration check notmeeting accuracy specifications. The actual reporting limit for this analyte may be higherthan the reported value. Methyl tert-butyl ether (+26.1%) was UJ-coded in samples 17, 41, 31, 32, 33, 33-FD, 19,20-FD, 25, 2, 3, 4, 4-FD, 5, 6, 7, 8, 9, 10, 10-FD, 11, 12, 13, and 14. This analyte was notfound in the samples at or above the reporting limit, however, the reporting limit is anestimate (UJ-coded) due to the continuing calibration check not meeting accuracyspecifications. The actual reporting limit for this analyte may be higher than the reportedvalue.

Naphthalene (-42.1%)was J-coded in sample 19. Although the analyte in question hasbeen positively identified in the samples, the quantitation is an estimate (J-coded) due tothe continuing calibration check not meeting accuracy specifications. The actualconcentration for this analyte may be lower than the reported value. Methyl tert-butyl ether (+26.5%) was UJ-coded in samples 20, 15, 16, 18, 30 and 1. Thisanalyte was not found in the samples at or above the reporting limit, however, thereporting limit is an estimate (UJ-coded) due to the continuing calibration check notmeeting accuracy specifications. The actual reporting limit for this analyte may be higherthan the reported value. Naphthalene (-38.8%) was J-coded in sample 19. Although the analyte in question hasbeen positively identified in the samples, the quantitation is an estimate (J-coded) due tothe continuing calibration check not meeting accuracy specifications. The actualconcentration for this analyte may be lower than the reported value. Methyl tert-butyl ether (74%, 82%-116%) was UJ-coded in samples 17, 41, 31, 32, 33,33-FD, 19, 20-FD, 25, 2, 3, 4, 4-FD, 5, 6, 7, 8, 9, 10, 10-FD, 11, 12, 13, and 14. Thisanalyte was not found in the samples at or above the reporting limit, however, thereporting limit is an estimate (UJ-coded) due to low recovery of this analyte in thelaboratory control sample. The actual reporting limit for this analyte may be higher thanthe reported value. Naphthalene (142%, 80%-123%) was J-coded in sample 19. Although the analyte inquestion has been positively identified in the samples, the quantitation is an estimate (J-coded) due to high recovery of this analyte in the laboratory control sample. The actualconcentration for this analyte may be lower than the reported value.

Methyl tert-butyl ether (73%, 82%-116%) was UJ-coded in samples 20, 15, 16, 18, 30 and1. This analyte was not found in the samples at or above the reporting limit, however, thereporting limit is an estimate (UJ-coded) due to low recovery of this analyte in thelaboratory control sample. The actual reporting limit for this analyte may be higher thanthe reported value. Methyl tert-butyl ether (71%, 75%-119%) was UJ-coded in sample 34. This analyte wasnot found in the sample at or above the reporting limit, however, the reporting limit is anestimate (UJ-coded) due to low recovery of this analyte in the laboratory matrix spike. Theactual reporting limit for this analyte may be higher than the reported value. Bromodichloromethane (6.4RPD, 6.1PCL) and 1,2-Dichloroethane (6.4RPD, 6.3PCL) wereUJ-coded in sample 17. These analytes were not found in the sample at or above thereporting limit, however, the reporting limit is an estimate (UJ-coded) due to poor precisionobtained for these analytes in the laboratory matrix spike and matrix spike duplicate. Theactual reporting limit for these analytes may be higher than the reported value.

21 Actual samples were analyzed with this ASR. There was insufficient sample volume torun a 2nd set of spikes, as required by the method. The Matrix Spike and Spike Duplicateanalyzed met criteria, as did the Field Duplicate, indicating data quality was acceptable.

Samples 101 (19hrs past), 102-108 (1 - 5.5hrs past) and 124FB (32hrs past) wereanalyzed past the 14-day holding times, due to instrument issues causing delay. Sample101 had good Spike and Spike Duplicate data, and as other times were close, samples 101-108 were not coded. Sample 124FB has been UJ-coded for all analytes except Acetone,which was J-coded.

Sample 152FB had no data to report, as the sample was lost during 2 failed sample runs,due to instrument malfunction.

All samples, except 124FB, were diluted to reduce interference from precipitate in thesample vials. They have been reported at a dilution of 2X with a raised reporting limit.

Samples 107, 108, 109, 111, and 112 required dilution for Acetone. Samples 108 and 109required dilution for Carbon Tetrachloride. Sample 108 required dilution for Chloroform.Sample 111 required dilution for Tetrachloroethene.

Acid preservation was buffered by the addition of Ascorbic acid. All samples were betweena pH of 2 and 4. The presence of the Ascorbic Acid has been shown to preserve theanalytes in the samples, so no data were coded.

1,2-Dichloropropane (87%, LCL: 89%), 1,2-Dibromoethane (85%, LCL: 87%), and EthylBenzene (89%, LCL: 90%) were UJ-coded in samples 112-116, 118 and 130. Theseanalytes were not found in the samples at or above the reporting limit, however, thereporting limit is an estimate (UJ-coded) due to low recovery of these analytes in thelaboratory control sample. The actual reporting limit for this analyte may be higher thanthe reported value. Sample 124FB was already coded for holding time, so no furthercoding was required for these analytes.

Chloroethane (83%, LCL: 84%), 1,2-Dibromoethane (89%, LCL: 90%) and 1,3-Dichlorobenzene (89%, LCL: 91%) were UJ-coded in sample 101. These analytes were notfound in the sample at or above the reporting limit, however, the reporting limit is anestimate (UJ-coded) due to low recovery of these analytes in the laboratory matrix spikeand/or spike duplicate. The actual reporting limit for these analytes may be higher thanthe reported value.

Dilutions were necessary in order to obtain valid results due to matrix interferences forsamples 3, 4, 4 FD, 5, 6, 7, 8, 9, 10, 10 FD, 11, 12, 13, 14, 15, 16, 17, 22, 22 FD . Thisincreased the reporting limits by a factor of 10000 for these samples.

Sulfate (131, 80-120) was J-coded in sample 18. Although the analyte in question hasbeen positively identified in the sample, the quantitation is an estimate (J-coded) due tohigh recovery of this analyte in the laboratory matrix spike. The actual concentration forthis analyte may be lower than the reported value.

Region 7 EPA Laboratory - Kansas City, Ks.Lab:

EPA Region 7 RLAB Method 3230.1FMethod:

Permanganate and/or Ascorbic Acid in the samples caused significant interference with theanalysis, with Internal Standards and Surrogates having lowered response. This requiredseveral dilutions to analyze the samples. Many samples could not be rerun due to lack ofsample volume, and have been reported with the lowest reporting limit available.

Samples 104FD, 105-109, 111-115, 122, 122FD, 124FB and 153FB were diluted to reduceinterference from Ascorbic Acid in the sample vials. They have been reported at a dilutionof 4X with a raised reporting limit.

Samples 110, 110FD, 116 and 126 were diluted to reduce interference from Ascorbic Acidin the sample vials. They have been reported at a dilution of 10X with a raised reportinglimit.

Samples 117 was diluted to reduce interference from Ascorbic Acid in the sample vial andto capture the high Tetrachloroethene value. It has been reported at a dilution of 20X witha raised reporting limit.

Sample 103 required a 10x dilution for Tetrachloroethene.

Sample 106 required a 500X dilution for Tetrachloroethene.

Samples 112 required a 20X dilution for Tetrachloroethene.

Samples 122 and 122FD required a 100X dilution for Tetrachloroethene.

Carbon Tetrachloride was over the calibration range in sample 108. This compound hasbeen J-coded to indicate that it is an estimate. The value calculated is within the expectedlinear range of the curve, so data should be usable for its intended purpose.

Tetrachloroethene was over the calibration range in samples 109 and 111. This compoundhas been J-coded to indicate that it is an estimate, and may be higher than the reportedvalues.

Due to permanganate/ascorbic acid issues, and repeated analyses, there was not sufficientsample volume to perform the required matrix spikes and spike duplicates. One matrixspike was performed, and one lab duplicate was reported.

Acid preservation was buffered by the addition of Ascorbic acid. Almost all samples werebetween a pH of 2 and 4. The presence of the Ascorbic Acid has been shown to preserve

the analytes in the samples better than the addition of acid alone, as the presence ofpermanganate tends to have a negative effect on the analytes of interest.

Methyl Acetate was UJ-coded in samples 102, 103, 104 110FD, 108, 109, 111, 112, 113,114, 115, 122, 122FD, 124FB, 153FB. This analyte was not found in the samples at orabove the reporting limit, however, the reporting limit is an estimate (UJ-coded) due to thecontinuing calibration check not meeting accuracy specifications. The actual reporting limitfor this analyte may be higher than the reported value.

Dichlorodifluoromethane, Chloromethane, Chloroethane and Cyclohexane were UJ-coded insamples 102, 103 and 104. These analytes were not found in the samples at or above thereporting limit, however, the reporting limit is an estimate (UJ-coded) due to thecontinuing calibration check not meeting accuracy specifications. The actual reporting limitfor these analytes may be higher than the reported value.

Acetone was J-coded in samples 102, 103, 104, 110FD, 108, 109, 111, 112, 113, 114, 115,122, 122FD and 153FB, and UJ-coded in 124FB. The reporting limit, or quantitation is anestimate (J-coded, UJ-coded for 124FB) due to the continuing calibration check not meetingaccuracy specifications. The actual concentration for this analyte may be different than thereported values. Acetone also had poor precision in samples 103 and 103LD.

2-Butanone and 2-Hexanone were UJ-coded in samples 110FD, 108, 109, 111, 112, 113,114, 115, 122, 122FD, 124FB and 153FB. Theses analytes were not found in the samplesat or above the reporting limit, however, the reporting limit is an estimate (UJ-coded) dueto the continuing calibration check not meeting accuracy specifications. The actualreporting limit for these analytes may be higher than the reported value.

Benzene and 1,2-Dichloropropane were UJ-coded in samples 102, 103, 104. Theseanalytes was not found in the samples at or above the reporting limit, however, thereporting limit is an estimate (UJ-coded) due to low recovery of these analytes in thelaboratory control sample. The actual reporting limit for these analytes may be higher thanthe reported value.

Bromoform, 1,2-Dibromo-3-Chloropropane, Dibromochloromethane, 1,2-Dibromoethane,trans-1,3-Dichloropropene, 2-Hexanone, 4-Methyl-2-Pentanone, Naphthalene, 1,1,2,2-Tetrachloroethane, 1,2,3-Trichlorobenzene and 1,1,2-Trichloroethane were UJ-coded insample 102. These analytes were not found in the sample at or above the reporting limit,however, the reporting limit is an estimate (UJ-coded) due to low recovery of this analytein the laboratory matrix spike, most likely due to the presence of Permanganate. Theactual reporting limit for this analyte may be higher than the reported value.

Sample 104 had all analytes associated with the internal standards Bromochloromethaneand Chlorobenzene-D5, and the surrogate 4-Bromofluorobenzene UJ-coded due to lowrecovery in the sample. These analytes include: Dichlorodifluoromethane, Chloromethane,Vinyl Chloride, Bromomethane, Chloroethane, Trichlorfluoromethane, 1,1,2-Trichlorotrifluoroethane, Methylene Chloride, Carbon Disulfide, 1,1-Dichloroethene, MethylAcetate, Methyl tert-butyl Ether, 1,1-Dichloroethane, trans-1,2-Dichloroethene, Chloroform,cis-1,2-Dichloroethene, 1,1,1-Trichloroethane, Carbon tetrachloride, 2-Butanone,Cyclohexane, 1,2-Dibromoethane, 1,3-Dichlorobenzene, 1,2-Dichlorobenzene,
