Re: McGuinness Property, Rotax Road, Monkton VT:

Report of Site Investigation

Spill #2014WMD184

SMS Site #2014‐4506

Dear George:

At your request, Vanasse Hangen Brustlin (“VHB”) has prepared this letter‐report to present the

findings and conclusions of the investigation into the discovery of pentachlorophenol (“PCP”) at the

water supply spring that formerly supplied the McGuinness property at 673 Rotax Road in Monkton,

VT. The spring is located on a separate property currently owned by Vermont Gas Systems, Inc., and

both locations are collectively referred to as “the Site” in this report. The investigation was conducted

on behalf of the Vermont Electric Power Company (“VELCO”) as requested by the Vermont Agency

of Natural Resources (“ANR”) in correspondence regarding VT Department of Environmental

Conservation (“DEC”) Spill #2014WMD184, dated April 29, 2014. The investigation was completed in

accordance with VHB’s written work plan dated May 15, 2014 that was approved by the ANR on May

30, 2014.

In brief, the site investigation included the completion of nine soil borings, and installation of water

table monitoring wells in seven of the borings to evaluate subsurface geologic and hydrologic

conditions, and to enable testing of soil and groundwater for contaminants of concern. The

investigation also included the analysis of potable water from the new bedrock well that now supplies

the residence, water from the existing spring that was formerly used as a source of drinking water, and

surface water from two locations along a drainage swale originating near the spring. The investigation

also involved laboratory analysis of samples of the treated utility pole (structure #190) that was the

alleged source of the PCP. As discussed in detail below, the results of the investigation are that as of

June 2014, concentrations of all tested parameters at the site in soil, groundwater, and the swale met

the applicable environmental and drinking water standards.

1.0 Background Information

The location of the site is shown on page 1 of the Attachment.

PCP was initially detected in the McGuinness spring in a sample collected by VELCO on April 17,

2014, after the utility pole replacement work had commenced and the residents had stated that

odors and sediments were observed in the water. The source of the PCP contamination was alleged

to be associated with the recent VELCO transmission line work in the vicinity of the Site involving

the replacement of structure #190, a treated wood utility pole structure. ANR requested that

VELCO complete this investigative work in correspondence dated April 29, 2014, as well as in an

email from Ashley Desmond of the VT DEC Sites Management Section (“SMS”), dated April 30,

2014.

Based on the initial detection of PCP in the McGuiness spring, VELCO contracted the construction

of a new bedrock well to replace the existing shallow water supply spring. The new well was

completed on May 8, 2014. The location of the new bedrock well is depicted on the maps on pages

2 through 4 of the Attachment and the well completion report is on page 5.

2.0 Pentachlorophenol Information

PCP is a semi‐volatile organic compound and is an Environmental Protection Agency (“EPA”)

and VT Agency of Agriculture registered pesticide, registered for use as a wood preservative.

PCP has a very low water‐solubility (14 mg/L in water at 20⁰ C) and high partitioning coefficients

(log kow = 5.12, log koc = 3.10 to 4.40) (HSDB, 2014). Due to these properties, PCP typically adsorbs

to soil and organic matter and has low mobility in the environment. Soil colloids may adsorb PCP,

causing stabilization of the colloids and enabling PCP to be transported by colloidal transport (US

EPA, 2008). Colloidal transport may occur in circumstances where soil particles are suspended in

flowing water such as overland runoff.

Normally, the vast majority of wood preservatives remain in the treated wood. If released into

the environment, these chemicals tend to adsorb to soils and biodegrade over time; biodegradation

may require several weeks for acclimation of bacteria. PCP is readily biodegradable in soil, surface

water, and wetlands. Biodegradation products include lower chlorinated phenols (e.g.

tetrachlorophenol, trichlorophenol, and dichlorophenol) as the process of reductive

dehalogenation eventually results in complete dechlorination to phenol which is subsequently

mineralized into carbon dioxide and methane gases (US EPA, 2008; D’Angelo and Reddy, 2000;

HSDB, 2014). Compounds such as dioxins and furans may be present in industrial‐grade PCP as

impurities in low concentrations, although 2,3,7,8‐TCDD in particular is not known to exist as an

impurity in PCP. Dioxins and furans have very low solubilities and high rates of soil sorption,

and tend to absorb to the treated wood and soil with little mobility in the environment (Arsenault,

1976; US EPA, 2008).

Studies of PCP and breakdown product concentrations in soils in the vicinity of in‐service utility

poles have found that concentrations of PCP are highest in the immediate vicinity of the poles and

rapidly decrease by several orders of magnitude within 3 to 12 inches from the poles.

Concentrations of PCP found at distances of 30 to 40 inches away from the poles were reported to

be non‐detectable and typical of environmental background conditions (Arsenault, 1976; Murarka

et al., 1996, US EPA, 2008).

3.0 Site Description

The Site is located in the Champlain Valley of western Vermont at an elevation of approximately

400 feet above mean sea level (“msl”). Topography is hilly and uneven; various rocky hills are

present surrounding the Site. The spring is situated near the base of a westward‐sloping hill and

structure #190 is located approximately 50 feet northeast and upslope from the spring. A wetland

complex is present to the west of the spring, and an intermittent drainage swale originates near the

spring and flows westward toward the wetland.

Surficial soils consist of silt loams and stony loams identified as the Raynham Silt Loam and

Amenia Stony loam in the area of the spring and structure #190, and Vergennes and Panton Clays

are also mapped in the general vicinity, according to the Natural Resources Conservation Service

(“NRCS”). The Surficial Geologic Map of Vermont (2008), identifies the surficial materials as

glaciolacustrine lake bottom sediments consisting of silty clay and/or clay containing ice rafted

boulders. Based on the lithology reported from the new bedrock well drilled at the residence, the

overburden soils are approximately 80 feet deep overlying bedrock. Specifically, the bedrock is

located beneath 79 feet of clay and hardpan soils, which impede the flow of water between the

shallow water table at the site and the deeper bedrock aquifer. This clay and hardpan layer acts as

an aquiclude, providing the bedrock aquifer with a substantial measure of protection against

contamination from surface spills at the Site (see well completion report, page 5 of the Attachment).

Bedrock at the site has been identified as Lower‐Cambrian‐aged Dunham Dolostone, a massive to

poorly bedded dolostone; and Middle‐Cambrian‐aged Monkton Quartzite, described as a pebbly

sandstone, well‐bedded dolostone, and reddish‐brown‐weathering dolomitic quartzite, according

to the Centennial Geologic Map of Vermont.

4.0 Work Completed

The following abbreviated chronology summarizes the key elements of the development of the

approved work plan and VHB’s on‐site investigation:

April 17, 2014 – VELCO collects a water sample from the McGuinness spring for analysis

of pentachlorophenol, PAHs, pesticides, and VOCs.

April 24, 2014 – the Vermont Department of Health collects a water sample from the

McGuinness spring for analysis of pentachlorophenol and herbicides

April 29, 2014 – ANR issues letter requesting five specific actions

May 8, 2014 – Chevalier Drilling Co. completes the installation of the new bedrock well

May 14, 2014 – Chevalier Drilling Co. collects a water sample from the bedrock well for

analysis of pentachlorophenol, VOCs, and other parameters

May 15, 2014 – VHB submits a work plan to the ANR to address three of the requests from

the ANR’s April 29 letter to

o assess impacts to the environment including but not limited to surface soil,

subsurface soil, groundwater, and drinking water;

o develop a work plan with an implementation schedule that details findings and

recommendations for additional work,

o provide updates and summary reports to the SMS as requested. Depending on

what work is determined necessary by the environmental consultant and SMS,

Mr. George Desch


July 28, 2014

Page 4 of 13

work may be performed in phases and findings of the work presented to the SMS

as completed and within timeframes established

May 30, 2014 – ANR approves the work plan with requests to:

o Complete onsite work by June 30, 2014

o Install soil borings/monitor wells in the vicinity of the McGuinness septic system

and greywater leachfield to investigate possible subsurface contamination from

discharge of water originating in the spring

o Resample the bedrock well for total barium and toluene, due to detections of these

substances in the water at concentrations below the Vermont Groundwater

Enforcement Standards (“VGES”), in a sample collected by the well driller

o Assess the need to pump‐out and clean the hot water and pressure tanks in the

residence

June 4, 2014 – VELCO informs VHB and ANR that it has addressed the above request

regarding the hot water and pressure tanks, as it has installed a new pressure tank, hot

water heater, water softener, and pre‐filter.

June 18, 2014 – VHB begins manual auguring and installation of monitoring wells on ‐site.

June 19, 2014 – VHB, VELCO, and ANR representatives meet on‐site. At the request of

ANR, the location for proposed monitoring well/soil boring MW‐1 is relocated from a

location north of structure #190 to a position near the drainage swale.

June 24, 2014 – VHB and subcontractor, ZEBRA Environmental Corp., complete soil

borings and monitor well installation using a track‐mounted GeoProbe rig.

June 26, 2014 – VHB measures water elevations and collects water samples with ANR

present. Per ANR direction, the downstream‐most swale sample specified in the work

plan is eliminated from the sampling program.

June 27, 2014 – VHB surveys the locations and elevations of all monitoring wells and

water testing locations, completing the on‐site portion of the work.

During June 24 and 26, 2014, VHB observed the completion of nine soil borings and installation of

monitor wells in seven borings, at the locations shown on the maps on pages 2, 3, and 4 of the

Attachment. Soil boring depths ranged from 3 to 16 feet below ground surface. Due to very rocky

conditions, soil borings SB‐5 and SB‐8 were unable to reach the water table despite multiple

attempts, and therefore no monitoring wells were installed in these two locations.

Contaminant Source Assessment

In accordance with the work plan, one sample of utility pole “butt‐end” shavings from the former

VELCO structure #190 utility pole was submitted for laboratory extraction and analysis for PCP

using EPA Method 8151A, as well as for PAH’s by Method 8270D. VHB compared the results of

this analysis to the prior tests of the McGuinness spring to identify the contaminants found in

common at both locations to determine the contaminants of concern for this site investigation.

Soil

VHB screened soils throughout the depth of each boring with a properly calibrated

photoionization detector (“PID”) equipped with an 11.2 eV lamp to determine gross levels of

volatile organic compounds (“VOCs”) using a plastic bag headspace method, and observed soils

for visual and olfactory evidence of contamination. Details of the borings, PID readings, field

observations, and monitor well construction details are provided on pages 6 through 11 of the

Attachment.

Mr. George Desch


July 28, 2014

Page 5 of 13

The work plan specified that if any visual, olfactory, or PID evidence of contamination is observed

in a soil boring, then samples would be collected from the depth of the strongest signs of

contamination within that boring, and submitted to Endyne, Inc (“Endyne”), a National

Environmental Laboratory Accreditation Conference (“NELAC”)‐accredited laboratory, for

analysis of PCP using EPA Method 515.4, and total petroleum hydrocarbons (“TPH”) using EPA

Method 8015‐DRO. However, most soil borings indicated no evidence of any contamination, as

no odors, staining, or PID readings above 0 ppm were observed with the exception of a PID

reading of 1.1 ppm at a depth of 9.5 to 11.5 feet below ground surface in SB‐8. In order to provide

sufficient soils analyses to characterize the site, in addition to a soil sample from SB‐8, VHB also

collected samples for laboratory analysis from borings designated SB‐5, MW‐6, and MW‐7, due to

their locations downslope of structure #190 and near the spring where the PCP had previously

been detected. Whereas no signs of contamination were identified in SB‐5, MW‐6, and MW‐7 to

guide the sampling depth, samples were taken from the depth of the soil/groundwater interface

in order to investigate the alleged groundwater contamination issue and to identify potential signs

of groundwater contamination.

Additionally, the work plan specified that VHB would also analyze select soil samples for

polynuclear aromatic hydrocarbons (“PAH’s”) by Method SW 8270C, and that soils to be analyzed

for PAHs will be selected based on the visual, olfactory, and PID observations. Again, whereas

no evidence of contamination was observed and the only PID reading above 0 ppm was the 1.1

ppm reading in SB‐8, in order to characterize the site thoroughly, samples for PAH analysis were

taken from borings designated SB‐5, MW‐6, MW‐7, and SB‐8. Soil samples were preserved on ice

and delivered to Endyne under a chain of custody for analysis within the proper sample holding

time.

Groundwater

On June 26, 2014 VHB measured groundwater levels in the shallow water table at the Site,

including in the spring and all monitor wells, on June 26, allowing the water levels in the newly

installed wells time to equilibrate.

After measuring groundwater levels, VHB acquired one groundwater sample from each

monitoring well and from the spring using low‐flow purge methods. The wells were purged using

a peristaltic pump and dedicated disposable tubing, until field‐measured parameters stabilized

(temperature, dissolved oxygen, specific conductance, pH, and oxidation‐reduction potential) or

the well went dry, indicating fresh groundwater was being pumped from the monitoring well.

Field sampling data are provided on pages 20 to 30 of the Attachment. The pump and tubing were

subsequently used for sample collection. Groundwater samples were preserved on ice and

delivered to Endyne under a chain of custody for analysis within the proper sample holding time.

In accordance with the work plan, groundwater samples from all monitoring points were analyzed

for PCP, a sample from the spring was analyzed for dioxins, and water samples from the spring

and monitoring wells MW‐6, MW‐7, and MW‐9 were also analyzed for PAH’s.

For this investigation, VHB also evaluated the results from samples taken from the spring water

collected by VELCO on April 17, 2014 and by the Vermont Department of Health on April 24, 2014.

Mr. George Desch

Drainage Swale

VHB acquired two standard grab samples on June 26, 2014 from the swale emanating from the

spring at locations approximately seven (7) and thirty (30) feet downstream from the spring

enclosure. The samples were preserved on ice and delivered to Endyne under a chain of custody

for analysis of PCP and PAH’s within the proper sample holding time.

Bedrock Potable Water Supply Well

The new bedrock well was initially sampled by Chevalier Drilling Co. on May 14 2014, and

analyzed at Endyne for various parameters consisting of coliform bacteria, metals (arsenic,

barium, and lead), VOCs (EPA method 524.2), PCP and phenoxy‐acid herbicides (EPA method

515.4), and gross alpha radioactivity (EPA method 900.0).

In accordance with the work plan, VHB acquired additional samples on June 26, 2014 of the

potable water from the new bedrock well in order to analyze for all regulated parameters

applicable to a private well, pursuant to Tables A‐11‐5 and A‐11‐7 of the Vermont Water Supply

Rule (2010), and for toluene (all EPA method 515.4 VOCs) and barium as requested by the ANR.

Samples were obtained at a tap in the basement of the McGuinness residence, upstream of the

softener and pre‐filter in order to provide a representative sample of the well water. Prior to

collecting the sample, VHB purged the well of approximately 125 gallons by running taps in the

residence. The samples were preserved on ice and delivered to Endyne under a chain of custody

for analysis within the proper sample holding time.

5.0 Findings

Contaminant Source Assessment

VHB compared the results of the analysis of the utility pole “butt‐end” shavings from the former

VELCO structure #190 utility pole, to the prior tests of the McGuinness Spring to identify the

substances found in common at both locations, which were found to consist of the following:

Anthracene

Fluorene

1‐Methylnaphthalene

2‐Methylnaphthalene

Pentachlorophenol

Phenanthrene

These semi‐volatile organic compounds have been thus identified as the contaminants of concern

for this site and consist of the pentachlorophenol and constituents of the carrier oil used in the

wood preservative. Relative proportions of these substances are similar between the April 17,

2014 sample of the spring water, and the pole shavings sample. Page 12 of the Attachment

summarizes the lab results for the contaminants of concern from the utility pole sample, and page

13 summarizes the results from the groundwater samples, including the spring. Complete lab

reports are on pages 31 to 97 of the Attachment.

Structure #190 replacement site work commenced on March 26, 2014, with installation of erosion

control measures, soil auguring, and excavation. The McGuinness’ reported observing a fuel‐oil

like smell in the water that night, although VELCO staff were unable to verify the odor the next

day. Bottled water was provided for drinking, and VELCO continued to work with the

McGuinness’ to address the situation, leading to the initial detection of pentachlorophenol in the

water sample collected from the spring on April 17, 2014. During this time period, weather was

typical early spring conditions, with a mix of above‐ and below‐freezing temperatures, melting of

snow on the ground, and both rain and snow falling at times (see pages 98 to 101 of the Attachment

for National Weather Service summaries). These conditions most likely resulted in substantial

amounts of surface runoff as rainfall and snowmelt would have flowed over mostly frozen

ground. Runoff may have transported soil, and adsorbed materials, dislodged from the

excavation at structure #190 downslope towards the McGuinness spring.

Groundwater

Groundwater was encountered from depths of less than one foot below grade in MW‐1 and the

spring, to nearly 13 feet below grade in MW‐2. Groundwater elevations are tabulated on page 19

of the Attachment. A groundwater contour map based on the water elevations measured in the

shallow water table on June 26, 2014 is presented in page 2 of the Attachment. Groundwater in the

water table at the site was determined to be flowing to the northwest, moving generally from the

likely recharge area in the high terrain east of Rotax Road toward groundwater discharge zones in

the wetland complex situated west of the study area. Measured gradients were steepest on the

eastern portion of the study area below the greywater and septic leachfields, and were more

gradual near the base of the slope around the spring and structure #190. From the location of

structure #190, groundwater was flowing northwest at a low gradient of approximately 0.6%,

whereas the spring is located to the southwest of structure #190, and is cross‐gradient from it.

Groundwater quality results for the contaminants of concern are summarized on the Water

Sampling Results Map on page 4 of the Attachment, and are tabulated on page 13 of the

Attachment. Groundwater was observed to be free of odors, sheens, or other signs of

contamination. All concentrations have been compared to the VGES and Preventive Action Levels

(“PAL”). Full laboratory results are included on pages 31 to 97 of the Attachment.

The only groundwater sampling location on the site where PCP or other contaminants had been

detected is the spring itself, and concentrations of these contaminants have decreased since April

2014, to non‐detectable levels. PCP had been detected in the McGuinness Spring in April 2014 at

concentrations up to 7.02 ug/L, which exceeded the VGES of 1 ug/L. However, as of the June 26,

2014 sampling event, no PCP was detectable in the spring (detection limit of 0.5 ppb). Dioxins were

found in the spring in the June 26 2014 sampling event, although no TCDD was detected, and all

tested water quality in the spring from June 2014 complied with the GES and PAL.

No PCP or other PAH contaminants have been detected in groundwater in any of the monitoring

wells. No contaminants were found in soil or groundwater near the septic and greywater

leachfields (MW‐9).

Drainage Swale

Results for the contaminants of concern from the samples from the swale are tabulated on page 14

of the Attachment; complete laboratory reports are included on pages 29‐95.

At the sample location seven feet downgradient from the spring enclosure, a faint petroleum odor

was observed during sampling, and PCP was detected at 0.62 ug/L. No olfactory evidence of

Mr. George Desch


July 28, 2014

Page 8 of 13

contamination was noted further downstream at the point 30 feet from the spring enclosure, and

no PCP was detected at this location. No other contaminants were detected in the swale. The water

quality test results from the swale meet the Vermont Water Quality Standards (2011).

Bedrock Potable Water Supply Well

Water from the new bedrock well meets all Vermont drinking water standards, and no PCP or

associated contaminants were detected in the well water. Although low levels of toluene (1.4 ug/L)

were found in the well water from the May 2014 sample, no toluene was detected in the June 2014

sample. Levels of the naturally occurring mineral barium are consistent between the two sample

events (0.043 and 0.045 mg/L in May and June, respectively) which is far below the public drinking

water standard of 2.0 mg/L.

All potable water test results are tabulated and compared to Vermont drinking water Maximum

Contaminant Levels (“MCL”), Vermont Health Advisory Levels, and Vermont Action Levels on

pages 15 to 16 of the Attachment. Full laboratory reports are included on pages 31 to 97 of the

Attachment. Table 1 below presents a simplified summary of the potable water results, presenting

all parameters that were detected in the well water, along with all regulated parameters applicable

to a private well, whether or not detected.

Soils

Soil logs are presented on pages 6 to 11 of the Attachment. Soils throughout the Site were generally

a mix of cobbly gravel, sand, and silt, with minor amounts of clay, consistent with the NRCS

mapping and soil descriptions.

Laboratory results for the key contaminants of concern in soils are summarized on the Soil

Sampling Results Map on page 3 of the Attachment and are tabulated on page 18 of the Attachment,

where they are compared to the EPAs Region 9 Regional Screening Level (“RSLs”, EPA 2013) and

the VT DEC Soil Screening Values (“SSVs”) (ANR, 2012) for industrial and residential soil. Full

laboratory results are included on pages 31 to 98 of the Attachment.

No PCP, PAH contaminants, or non‐target Unidentified Peaks have been detected in soil at the

Site. The only contaminant detections in soil consisted of TPH (non‐compound‐specific test) in

MW‐6, which is the nearest monitor well upslope from the spring, located about 6 feet northeast of

the spring enclosure and about 45 feet southwest of structure #190. All soil testing results are in

conformance with the EPA RSLs and the VT DEC SSVs (TPH does not have a RSL or SSV value).

6.0 Discussion and Conclusions

The site investigation has determined that PCP and associated contaminants had been present in

the McGuinness spring and in a segment of the drainage swale originating from near the spring.

Mr. George Desch


July 28, 2014

Page 10 of 13

As of June 26, 2014, PCP was no longer detectable in the spring, and concentrations of all tested

parameters at the Site met the applicable environmental and potable water standards.

Water in the McGuinness spring likely originates as groundwater discharge from the

shallow water table and underlying bedrock. Regional groundwater is most likely

recharged from rainfall and snowmelt in the higher elevation terrain to the east and

northeast, and flows generally to the west towards a large wetland complex located about

¼ mile southwest of the spring. Based on topographic contours, the spring is located

approximately 50 feet downslope and southwest of the structure #190 utility pole that was

replaced during the spring of 2014. Based on groundwater contours measured in June

2014, groundwater from the structure #190 utility pole flows to the northwest and

therefore, the spring is hydrologically cross‐gradient from the structure #190 utility pole.

Very low levels of dioxins were detected in the spring in June 2014, at concentrations that

met the VGES and PAL. No TCDD was detected in the spring water. These contaminants

may have originated as impurities in the PCP wood preservative.

Concentrations of PCP measured in the spring were 7.02 ug/L on April 17, 2014, 1.6 ug/L

on April 24, 2014, and no PCP was detected above the 0.5 ug/L detection limit on June 26,

2014, indicating declining concentrations. Likewise, other contaminants detected in the

spring in April 2014 (Anthracene, Fluorene, 1‐Methylnaphthalene, 2‐Methylnaphthalene,

and Phenanthrene) also were not detectable in the June 2014 sampling event. The decline

suggests a “one‐time” release that had been discontinued by mid‐April 2014, and that fresh

water flushing the spring resulted in non‐detectable levels of PCP and these associated

PAH contaminants.

The northwest flow direction of groundwater from structure #190, and the absence of PCP

and PAH contaminants in soil and groundwater between structure #190 and the spring,

both indicate that the contaminants found in the spring did not migrate through soil or

groundwater. Due to the high sorption and poor solubility of these contaminants, they

most likely would have been found adsorbed to soil in borings MW‐4, SB‐5, and/or MW‐6

had they been transported through groundwater to the spring.

The most likely explanation for the detections of PCP and associated contaminants in the

McGuinness spring is that during work to remove the former structure #190 pole, while

the ground was frozen, soils immediately adjacent to the pole containing PCP were

disturbed and soil colloids with adsorbed PCP and associated substances were transported

by overland runoff towards the spring, despite the use of erosion controls, due to rainfall

and snowmelt. This water and colloidal particles may have entered the concrete spring

enclosure by infiltrating through the backfilled soil adjacent to the enclosure, and being

drawn into the spring while it was being pumped to supply water to the residence (VELCO

was providing the McGuinness’ with bottled water for drinking at the time work was

performed on structure #190, however spring water was still being used for other

purposes).

Mr. George Desch


July 28, 2014

Page 11 of 13

The absence of detectable PCP and PAH contaminants in soils at SB‐8 and MW‐9, and in

groundwater at MW‐9, confirms that contaminants of concern were not spread through

the greywater or septic systems.

During June 2014, PCP was only found in one location on‐site, which is the swale sample

collected approximately 7 feet downstream of the spring, where it was identified at a

concentration of 0.62 ug/L. All water quality testing results from the swale were in

conformance with the Vermont Water Quality Standards. Further downstream in the

swale (30 feet downstream of the spring) no PCP was detected, confirming that

contamination was not extending down the swale to the wetlands located further to the

west.

Considering the declining contaminant levels and the short duration when PCP was

detected in the spring, the low levels of remaining PCP in the swale and dioxins in the

spring are expected to continue to dissipate.

Water from the new bedrock well meets all drinking water standards, and no PCP or

associated contaminants were detected in the well water. After an initial detection of a low

concentration of toluene, within the drinking water standards, in the well during May

2014, toluene was not detected in the June 2014 sampling event. Toluene is frequently

detected temporarily in low levels in newly drilled wells, but typically does not persist,

and is likely be related to the well drilling equipment or newly installed plumbing fittings.

The location of the bedrock well is upgradient from the area where contaminants were

found in shallow groundwater, and the layers of clay and hardpan above the bedrock

signify that the bedrock aquifer is hydrogeologically isolated from the shallow water table

where PCP was detected. Therefore the new bedrock well is a suitable replacement water

supply and is not vulnerable to contamination.

Findings of this investigation are consistent with prior studies by utilities of environmental

fate and transport of PCP and its impurities and breakdown products (e.g., Arsenault,

1976, Murarka et al., 1996, US EPA, 2008), in that these contaminants were not found in

soils beyond the immediate vicinity of the utility pole. The temporary presence of PCP

and certain associated PAHs in the spring suggests an anomalous event in which colloidal

transport of soil particles with adsorbed contaminants occurred as a result of soil

disturbance when structure #190 was being replaced. Results of this investigation

corroborate these prior studies in concluding that widespread soil or groundwater

contamination surrounding PCP‐treated utility poles was not observed.

7.0 Recommendations

Based on the Conclusions above, VHB recommends the following:

No further site investigation or mitigation is recommended, because of the following

conclusions:

o the new bedrock well is providing an acceptable source of potable water to the

McGuinness residence;

o the extent and degree of contamination have been delineated, and are very

limited;

Mr. George Desch

o no PCP was detectable at the downstream‐most swale sample, confirming that

contamination was not extending down the swale to the wetlands; and

o as of June 2014, concentrations of all tested parameters at the site in soil,

groundwater, the drainage swale, and potable water met the applicable

environmental and drinking water standards.

The contamination of the McGuinness spring appears to be the result of a “one‐time”

incident from the replacement of Structure #190 and overland flow, rather than an ongoing

release of contaminants to groundwater from the long term presence of the utility poles.

Groundwater and surface water have been thoroughly characterized around the spring

where contamination was located, therefore the installation of additional groundwater

monitoring wells in a location downgradient from the structure (e.g. the originally

proposed MW‐1 site) is not recommended.

The Site meets the requirements of section 7.1.1. of the Vermont ANR Investigation and

Remediation of Contaminated Properties (“IROCP”) Procedure (2012) and therefore is

eligible for a Sites Management Activities Completed (“SMAC”) designation. With the

concurrence of ANR, VELCO will arrange for the abandonment of all site monitoring wells

and of the spring, and would subsequently report the completion of well closure so that a

SMAC designation letter may be issued.

Please do not hesitate to call me if you have any questions.

Sincerely,

*Surface Water Quality Standards for Pentachlorophenol are expressed as exp(1.005 (pH) ‐ 4.830) for Acute criteria, and as exp(1.005 (pH)

5.290) for Chronic criteria. Standards were calculated based on pH of 7.49 measured during low‐flow purge analysis at the spring on site

(6/26/2014). The swale is not used as a source for consumption of water or organisms and therefore the human health criteria are not

Enclosed please find the results of the analyses performed for the samples referenced on the attached chain of custody. All required method quality control elements including instrument calibration were performed in accordance with method requirements and determined to be acceptable unless otherwise noted.

The column labeled Lab/Tech in the accompanying report denotes the laboratory facility where the testing was performed and the technician who conducted the assay. A "W" designates the Williston, VT lab under NELAC certification ELAP 11263; "R" designates the Lebanon, NH facility under certification NH 2037 and “N” the Plattsburgh, NY lab under certification ELAP 11892. “Sub” indicates the testing was performed by a subcontracted laboratory. The accreditation status of the subcontracted lab is referenced in the corresponding NELAC and Qual fields.

The NELAC column also denotes the accreditation status of each laboratory for each reported parameter. “A” indicates the referenced laboratory is NELAC accredited for the parameter reported. “N” indicates the laboratory is not accredited. “U” indicates that NELAC does not offer accreditation for that parameter in that specific matrix. Test results denoted with an “A” meet all National Environmental Laboratory Accreditation Program requirements except where denoted by pertinent data qualifiers. Test results are representative of the samples as they were received at the laboratory

KATAHDIN ANALYTICAL SERVICES – INORGANIC DATA QUALIFIERS (Refer to BOD Qualifiers Page for BOD footnotes)

The sampled date indicated on the attached Report(s) of Analysis (ROA) is the date for which a grab sample was collected or the date for which a composite sample was completed. Beginning and start times for composite samples can be found on the Chain-of-Custody. U Indicates the compound was analyzed for but not detected above the specified level. This level may be the Limit

of Quantitation (LOQ)(previously called Practical Quantitation Level (PQL)), the Limit of Detection (LOD) or Method Detection Limit (MDL) as required by the client.

Note: All results reported as “U” MDL have a 50% rate for false negatives compared to those results reported as “U” PQL/LOQ or “U” LOD, where the rate of false negatives is <1%.

E Estimated value. This flag identifies compounds whose concentrations exceed the upper level of the calibration

range of the instrument for that specific analysis. J Estimated value. The analyte was detected in the sample at a concentration less than the laboratory Limit of

Quantitation (LOQ)(previously called Practical Quantitation Limit (PQL)), but above the Method Detection Limit (MDL).

I-7 The laboratory’s Practical Quantitation Level could not be achieved for this parameter due to sample composition,

matrix effects, sample volume, or quantity used for analysis. A-4 Please refer to cover letter or narrative for further information. H_ Please note that the regulatory holding time for _______ is “analyze immediately”. Ideally, this analysis must be

performed in the field at the time of sample collection. _______ for this sample was not performed at the time of sample collection. The analysis was performed as soon as possible after receipt by the laboratory.

H1 pH H2 DO H3 sulfite H4 residual chlorine T1 The client did not provide the full volume of at least one liter for analysis of TSS. Therefore, the PQL of 2.5 mg/L

could not be achieved. T2 The client provided the required volume of at least one liter for analysis of TSS, but the laboratory could not filter

the full one liter volume due to the sample matrix. Therefore, the PQL of 2.5 mg/L could not be achieved. M1 The matrix spike and/or matrix spike duplicate recovery performed on this sample was outside of the laboratory

acceptance criteria. Sample matrix is suspected. The laboratory criteria was met for the Laboratory Control Sample (LCS) analyzed concurrently with this sample.

M2 The matrix spike and/or matrix spike duplicate recovery was outside of the laboratory acceptance criteria. The

native sample concentration is greater than four times the spike added concentration so the spike added could not be distinguished from the native sample concentration.

R1 The relative percent difference (RPD) between the duplicate analyses performed on this sample was outside of

the laboratory acceptance criteria (when both values are greater than ten times the PQL). MCL Maximum Contaminant Level NL No limit NFL No Free Liquid Present FLP Free Liquid Present NOD No Odor Detected TON Threshold Odor Number

REPORT OF LABORATORY ANALYSIS

This report shall not be reproduced, except in full,without the written consent of Pace Analytical Services, Inc.

This report presents the results from the analysis performed on one sample submitted by a representativeof Endyne, Inc. The sample was analyzed for the presence or absence of polychlorodibenzo-p-dioxins(PCDDs) and polychlorodibenzofurans (PCDFs) using USEPA Method 1613B. The reporting limits werebased on signal-to-noise measurements. Estimated Maximum Possible Concentration (EMPC) valueswere treated as positives in the toxic equivalence calculations. The sample was received above therecommended temperature range of 0-6 degrees Celsius.

The recoveries of the isotopically-labeled PCDD/PCDF internal standards in the sample extract rangedfrom 44-74%. All of the labeled standard recoveries obtained for this project were within the target rangesspecified in Method 1613B. Also, since the quantification of the native 2,3,7,8-substituted congeners wasbased on isotope dilution, the data were automatically corrected for variation in recovery and accuratevalues were obtained. Concentrations below the calibration range were flagged "J" and should beregarded as estimates.

A laboratory method blank was prepared and analyzed with the sample batch as part of our routine qualitycontrol procedures. The results show that PCDDs and PCDFs were not detected.

Laboratory spike samples were also prepared using clean water that had been fortified with nativestandard materials. The recoveries of the native compounds ranged from 87-116% with relative percentdifferences of 0.0-10.4%. These results indicate high degrees of accuracy and precision for thesedeterminations. Matrix spikes were not prepared with the sample batch.

The labeled cleanup standard in the sample batch was inadvertently omitted from the extracts prior to thecleanup steps and subsequently added at the end of the preparation steps. This deviation from thestandard procedures did not impact the accuracy of the native congener determinations.
