EXECUTIVE SUMMARY

This Phase II Environmental Site Assessment (Phase II ESA) Report presents the results of soil and

groundwater sampling activities performed at the property located at 3229 San Leandro Street in

Oakland, California (Site) (Figure 1). The Site comprises Assessor’s Parcel Number 033-2186-003-01 and

is located in an area of Oakland that has historically been a mix of commercial/light industrial and

residential land use. The Site is currently occupied by two small metal storage buildings, machine parts,

a flat bed trailer, and a truck with a hoist. The Site was most recently used for storage by a marine

facilities construction company, but is currently vacant.

This Phase II ESA was performed to assess potential environmental conditions at the Site based on the

results of a Phase I ESA performed by Treadwell and Rollo, Inc. (Treadwell & Rollo, 2009a). The Phase I

ESA noted extensive staining by oil or other hazardous materials or petroleum products on pavement in

various locations around the Site and other potential recognized environmental conditions at the Site.

These conditions included an area where a former building burned, and historic use by facilities that

commonly use hazardous materials or petroleum products.

To assess the environmental conditions at the Site, Treadwell & Rollo collected soil samples from five soil

borings on the Site. Groundwater samples were scheduled to be collected from two locations (SLTR-1

and SLTR-2), but groundwater was not encountered in these borings. Analytical results were compared

with Regional Screening Levels (RSLs) established by the United States Environmental Protection Agency

(EPA) and Environmental Screening Levels (ESLs) established by the California Regional Water Quality

Control Board, San Francisco Bay Region (RWQCB). Soil results were evaluated with respect to soil RSLs

and ESLs for both residential and industrial land use. The residential land use values were used to

provide a broader range of potential future land uses.

Chemicals detected in soil at the Site included volatile organic compounds (VOCs), organochlorine

pesticides (OCPs), petroleum hydrocarbons, and metals.

1.0 INTRODUCTION

This Phase II Environmental Site Assessment (Phase II ESA) Report presents the results of the recent

activities to characterize and assess potential environmental conditions at the property located at

3229 San Leandro Street in Oakland, California (Site) (Figure 1). This assessment was performed in

general accordance with Treadwell & Rollo’s Proposal for Phase II Environmental Site Assessment,

3229 San Leandro Street, Oakland, California, dated 15 July 2009 (T&R, 2009b). Treadwell & Rollo

performed this assessment to evaluate the potential for soil and/or groundwater contamination at the

Site and identify the source or sources of contamination. To do this, Treadwell & Rollo collected and

analyzed soil samples for chemical laboratory analysis of organic chemicals and metals. No groundwater

was encountered at the Site to the maxium depth explored. Therefore, no groundwater samples were

collected from the Site.

The following sections include a Site description, a summary of previous investigations, a summary of

field activities, a discussion of analytical results, and our conclusions and recommendations.

2.0 BACKGROUND

2.1 Site Description

The Site consists of the property located at 3229 San Leandro Street, and is bound to the northeast by

San Leandro Street (beyond which are residential properties), to the southeast and northwest by

commercial properties and to the southwest by a commercial property (beyond which is a railroad right-

of-way and railroad tracks). The Site is approximately ¼ acre in area and comprises Assessor’s Parcel

Number 033-2186-003-01 (Figure 2).

The Site is at an elevation of approximately 34 feet above Mean Sea Level (T&R, 2009a). The ground

surface in the Site vicinity slopes gently downward to the southwest. The Oakland inner harbor channel

is located approximately ½ mile southwest of the Site. San Francisco Bay is approximately two miles to

the southwest. Groundwater flow is variable in the vicinity of the Site, but the assumed general direction

49530402.OAK 2 16 October 2009

of groundwater flow is to the inner harbor channel. Groundwater at the Site is not considered a drinking

water source.

2.2 Previous Environmental Investigations

Previous environmental investigations were performed at the Site by Aqua Terra Technologies in 1988

and Treadwell & Rollo in June, 2009 (T&R, 2009a). The following discussion summarizes the results of

these studies.

2.2.1 Aqua Terra Technologies (ATT) - 1988

A 1988 Phase I ESA report prepared by ATT was reviewed at the Oakland Fire Department (OFD)

during the Treadwell & Rollo Phase I ESA. The ATT ESA mentioned a contaminant release at

3301 San Leandro Street (the adjacent property to the southwest) in 1988. The exact location of the

release was not determined, since the address of the Site (3229 San Leandro Street) and that of the

adjacent property were used interchangeably in many of the records examined by Treadwell & Rollo.

Due to the illegibility of the ESA report, no further information was obtained, and the release could not be

confirmed. It could not be determined if this reported release was related to the USTs that were

removed from that property.

2.2.2 Treadwell and Rollo - 2009

Treadwell & Rollo conducted a Phase I ESA in June, 2009. Based on the findings of the Phase I ESA, the

Site had several commercial/light industrial uses since the early twentieth century. The documented Site

uses were users of hazardous materials, and there was evidence of historical hazardous materials storage

at the Site. Treadwell & Rollo observed extensive staining of pavement at various areas around the Site

during a Site visit. In addition, vehicle storage and poor housekeeping practices were observed, as also

indicated by the staining.

3.0 FIELD INVESTIGATION

Treadwell & Rollo performed two field investigations, one on 5 August 2009 and another on

8 September 2009. Soil sampling was conducted in five locations (SLTR1-1 through SLTR1-5).

The boring locations are shown on Figure 3.

49530402.OAK 3 16 October 2009

Prior to drilling, a boring permit was obtained from the Alameda County Environmental Health

Department. Treadwell & Rollo also notified Underground Service Alert (USA) and subcontracted

Precision Locating of Brentwood, California, to survey and locate underground utilities at marked boring

locations. The following sections describe the drilling and sampling activities.

3.1 Soil Sampling

On 5 August 2009, Vironex, Inc. advanced three soil borings (SLTR1-1 through SLTR1-3). The borings

were advanced by direct push technology. Continuous cores were collected and the borings logged for

soil type using the Unified Soil Classification System (ASTM Standard D 2487). Soil at the Site is primarily

composed of fill to a depth of approximately 1.5 feet followed by alternating sandy clays and sandy silts

to a depth of approximately 10.0 feet below ground surface (bgs). On 8 September 2009, Vironex, Inc.

advanced two additional soil borings (SLTR1-4 and SLTR1-5) using direct push technology.

On 5 August 2009, two soil samples, one shallow and one deeper, were collected from SLTR1-1 through

SLTR1-3. Shallow samples were collected from depths ranging from 0.5 to 1.5 feet bgs. The deeper

samples, collected from depths ranging from 2.0 to 4.0 feet bgs, were placed on hold with the laboratory

pending shallow sample results. On 8 September 2009, one additional sample was collected from borings

SLTR1-4 and SLTR1-5 at a depth of 9.5 feet bgs. Samples were collected in six-inch plastic tubes cut

from the cores, capped, sealed, labeled and placed in chilled coolers for transport to Curtis and

Tompkins, Ltd. of Berkeley, California (Curtis and Tompkins) for analysis.

3.2 Groundwater Sampling

Groundwater samples were scheduled to be collected from two locations (SLTR-1 and SLTR-2).

After advancing boring SLTR-1 to 20 feet bgs and SLTR-2 to 15 feet bgs, no groundwater was

encountered. A temporary well was installed at SLTR-1 using 1-inch schedule 40 PVC with slotted screen

and left for one hour to determine if measurable groundwater would enter the well. After one hour, no

groundwater was found in SLTR-1. As a result, no groundwater samples were collected from the Site.

4.0 LABORATORY ANALYTICAL RESULTS

Soil samples were sent to Curtis and Tompkins for analysis. Selected soil samples were analyzed for

some or all of the following:

49530402.OAK 4 16 October 2009

• Volatile organic compounds (VOCs) by EPA Method 8260

• Semi-volatile organic compounds (SVOCs) by EPA Method 8270

• Total petroleum hydrocarbons quantified as gasoline (TPH-g) by EPA Method 8015

• Total petroleum hydrocarbons quantified as diesel (TPH-d) and motor oil (TPH-mo) by EPA

Method 8015, using the silica gel cleanup method

• Methyl tertiary butyl ether (MTBE) and benzene, toluene, ethylbenzene, and xylenes (BTEX) by

EPA Method 8021

• Organochlorine pesticides (OCPs) and polychlorinated biphenyls (PCBs) by EPA Method

8081/8082

• Leaking Underground Fuel Tank Manual (LUFT 5) metals (cadmium, chromium, lead, nickel and

zinc) by EPA Method 6010

• California Assessment Manual (CAM 17) Metals (antimony, arsenic, barium, beryllium, cadmium,

chromium, cobalt, copper, lead, mercury, molybdenum, nickel, selenium, silver, thallium,

vanadium and zinc) or single metals by EPA Method 6010/7470

• Dioxins and Furans by EPA Method 8290.

4.1 Soil Analytical Results Above 2.0 Ft bgs – 5 August 2009

To evaluate the concentrations of chemicals found in soil at the Site, detected concentrations were

compared with Regional Screening Levels (RSLs) of the United States Environmental Protection Agency

(EPA) (2009) and Environmental Screening Levels (ESLs)of the California Regional Water Quality Control

Board, San Francisco Bay Region (RWQCB) (interim final 2007, revised 2008). Chemical-specific EPA

RSLs for residential soil and industrial soil were used; no EPA RSLs have been developed for petroleum

hydrocarbons. Metal concentrations were also compared to local ambient metal concentrations in soil, as

calculated in - Analysis of Background Distributions of Metals in the Soil at Lawrence Berkeley National

Laboratory, Lawrence Berkeley National Laboratory (LBNL, 2002).

• The VOC tetrachloroethene (PCE) was detected at a depth of 0.5 ft bgs at SLTR1-3 at a

concentration of 0.13 milligrams per kilogram (mg/kg). The detected concentration did not

exceed the EPA residential or industrial RSLs or the RWQCB residential or industrial ESLs.

49530402.OAK 5 16 October 2009

• Several pesticides were detected in the sample from SLTR1-2 at a depth of 2.0 ft bgs. However,

with the exception of dieldrin, the detected concentrations did not exceed the EPA residential or

industrial RSLs or the RWQCB residential or industrial ESLs. Dieldrin was detected at a

concentration of 0.036 mg/kg which exceeds the EPA residential RSL and the RWQCB residential

and industrial ESLs. SLTR1-2 was located where the former building was burned and is currently

covered by vegetation. Pesticides can be very persistent in soils and the detected pesticides at

SLTR1-2 are potentially residue from former pest control practices.

• TPH-d and TPH-mo were detected in the sample from SLTR1-3 at concentrations of 590 and

2,900 mg/kg, respectively, at a depth of 0.5 ft bgs. These concentrations exceed the RWQCB

residential and industrial ESLs. EPA does not list RSLs for these compounds. TPH-d and TPH-mo

in the soil may be the result of historic storage of vehicles and equipment on the Site.

• Dioxins and furans were tested in the sample from SLTR1-2 at a depth of 2.0 ft bgs, where the

former building was burned. Dioxins and furans are often the result of combustion and can

remain in soil for a long period. No dioxins or furans were detected at levels that exceeded the

EPA residential and industrial RSLs or the RWQCB residential and industrial ESLs.

• Arsenic and vanadium were detected in the sample from SLTR1-2 at a depth of 2.0 ft bgs at

concentrations of 2.5 and 25 mg/kg, respectively. The arsenic concentration exceeds the EPA

residential and industrial RSLs and the RWQCB residential and industrial ESLs. The vanadium

concentration exceeds the RWQCB residential ESL. However, these concentrations may reflect

local natural background values which range between 0.3 to 42 mg/kg for arsenic and 0.79 to

120 mg/kg for vanadium (LBNL, 2002).

The analytical results are summarized in Tables 1, 2, and 3. Copies of the laboratory analytical reports

and chain-of-custody documentation are presented in Appendix A.

4.2 Soil Analytical Results Below 2.0 Ft bgs – 5 August 2009

Based on the shallow soil analytical results, the laboratory analyzed the sample from SLTR1-3 at 3.5 ft

bgs for TPH-d and TPH-mo and the sample from SLTR1-2 at 3.5 ft bgs for pesticides. TPH-d was

detected at a concentration of 2.1 mg/kg at 3.5 ft bgs at SLTR1-3. TPH-mo was not detected. This

49530402.OAK 6 16 October 2009

result does not exceed the RWQCB residential or industrial ESLs. No pesticides were detected in the

sample from SLTR1-2.

These analytical results are summarized in Tables 1 and 3. Copies of the laboratory analytical reports


4.3 Soil Analytical Results 9.5 Ft bgs – 8 September 2009

Based on the analytical results from soil sampling performed on 5 August 2009, additional sampling was

performed in two locations (SLTR1-4 and SLTR1-5) on 8 September 2009. The samples were analyzed

for VOCs, TPH-g, TPH-d, TPH-mo and CAM 17 metals. In addition, a duplicate sample from SLTR1-5

(SLTR1-5-9.5910’D) was analyzed for CAM 17 metals for Quality Assurance/Quality Control (QA/QC).

No VOCs, TPH-g, TPH-d, or TPH-mo were detected. Among the CAM 17 metals, arsenic, cobalt, nickel

and vanadium were detected in the sample from SLTR1-4 at concentrations of 3.6, 28, 240 and

40 mg/kg, respectively. The arsenic concentration exceeds the EPA residential and industrial RSLs and

the RWQCB residential and industrial ESLs. The cobalt concentration exceeds the EPA residential RSL.

The nickel concentration exceeds the RWQCB residential and industrial ESLs. The vanadium

concentration exceeds the RWQCB residential ESL. Arsenic and vanadium were detected in the sample

from SLTR1-5 at concentrations of 9.7 and 44 mg/kg, respectively. The arsenic concentration exceeds

the EPA residential and industrial RSLs and the RWQCB residential and industrial ESLs. The vanadium

concentration exceeds the RWQCB residential ESL. However, these concentrations may reflect local

natural background values which range between 0.3 to 42 mg/kg for arsenic, 0.92 to 29 mg/kg for

cobalt, 6.0 to 380 mg/kg for nickel, and 0.79 to 120 mg/kg for vanadium (LBNL, 2002). With the

exception of antimony which was not detected above the reporting limit in the primary sample from

SLTR1-5, but detected in the QA/QC sample SLTR1-5-9.5-10’D sample at a concentration of 2.4 mg/kg,

metal concentrations in the QA/QC sample correlated to those of the primary sample. These samples

measure laboratory precision by repeating analyses on similar samples. The laboratory QA/QC results

reported on the laboratory reports (Appendix A) were within acceptable parameters.

These analytical results are summarized in Tables 1 and 3. Copies of the laboratory analytical reports

5.0 CONCLUSIONS AND RECOMMENDATIONS

Treadwell & Rollo evaluated the potential for soil and/or groundwater contamination at the Site and has

the following conclusions.

• Soils are generally fine-grained and groundwater flow is limited.

• PCE, pesticides, TPH-d, and TPH-mo are present is shallow soil. Specifically our investigation

found the following:

• The VOC tetrachloroethene (PCE) was detected in one shallow soil sample in the southern

portion of the Site at a concentration that did not exceed the EPA residential or industrial RSLs,

or the RWQCB residential or industrial ESLs.

• Of the pesticides detected, dieldrin in one sample in the northern portion of the Site exceeded

the EPA residential RSL and the RWQCB residential and industrial ESLs. No pesticides were

detected in deeper soil at this location.

• Total petroleum hydrocarbons as diesel (TPH-d) and total petroleum hydrocarbons as motor oil

(TPH-mo) exceeded the RWQCB residential and industrial ESLs in one shallow soil sample in the

southeastern portion of the Site. EPA does not list RSLs for this compound. In a deeper sample

at this location, TPH-d was below the screening levels, and TPH-mo was not detected.

• Arsenic exceeded the EPA residential and industrial RSLs and the RWQCB residential and

industrial ESLs in three samples. Cobalt exceeded the EPA residential RSL in one sample. Nickel

exceeded the RWQCB residential and industrial ESLs in one sample. Vanadium exceeded the

RWQCB residential ESL in three samples. However, the detected concentrations were within the

local natural background levels for these metals in soil.

Treadwell & Rollo recommends that a soil mitigation plan (SMP) be prepared prior to redevelopment of

the Site to address mitigation of soil in the areas where PCE, petroleum hydrocarbons and pesticides

were found in shallow soil.

Semivolatile Organics by GC/MS (EPA 8270C) Water:No analytical problems were encountered.

Semivolatile Organics by GC/MS (EPA 8270C) Soil:SLTR1-1-1.5-2.0 (lab # 214030-001) and SLTR2-2-1.5-2.0 (lab # 214030-009)were diluted due to the dark and viscous nature of the sample extracts. Noother analytical problems were encountered.

Pesticides (EPA 8081B):All samples underwent sulfur cleanup using the copper option in EPA Method3660B. All samples underwent florisil cleanup using EPA Method 3620C. Matrixspikes were not reported for this analysis because the parent sample requireda dilution that would have diluted out the spikes. SLTR2-3-1.5-2.0 (lab #214030-011) was diluted due to the color of the sample extract. No otheranalytical problems were encountered.

CASE NARRATIVE


This data package contains sample and QC results for two soil samples,requested for the above referenced project on 08/24/09. The samples werereceived cold and intact.

TPH-Extractables by GC (EPA 8015B):214362-003 was prepared outside of hold time; affected data was qualifiedwith "b". No other analytical problems were encountered.

Pesticides (EPA 8081B):All samples underwent sulfur cleanup using the copper option in EPA Method3660B. All samples underwent florisil cleanup using EPA Method 3620C. Matrixspikes QC509144,QC509145 (batch 154215) were not reported because the parentsample required a dilution that would have diluted out the spikes. 214362-001was prepared outside of hold time; affected data was qualified with "b". Noother analytical problems were encountered.
