EXECUTIVE SUMMARY

At the request of the United States Department of Veterans Affairs (VA), Office of Construction and

Facilities Management, STV Incorporated (STV) conducted a Subsurface Investigation on a parcel of land on the FDR Campus, Westchester County, 2094 Albany, Montrose, New York 10548 (hereinafter referred to as the “Site”). A Site Location Map is presented in Figure 1.

FDR Campus in Montrose is a part of the The VA Hudson Valley Health Care System which also includes the Castle Point Campus in Dutchess County and several community based clinics.

The Site consists of a 44,000 square foot (SF) parcel situated on the northern end of the property. It consists of gravel surface to the east and a vegetative area to the west and is bounded by a chain link fence, streams and wooded area. Currently the property serves as a staging area for equipment, some vehicles and dumpsters. The Site location on the property is presented in Figure 2 (Site Aerial View

Map).

This scope of work was prepared in response to existing stormwater line concerns at Site. It was concluded that routing the stormwater line through an area in the vicinity of the Area of Investigation

(AOI) that had reportedly received historic fill material, provided the most direct routing but posed a potential concern with managing potentially contaminated historic fill during excavation and construction of the stormwater line extension. As a first step, the current extent of any soil/ fill impacts along the projected alignment of the proposed stormwater extension would be assessed with a geophysical survey and soil program. Based on these findings, the probability of encountering significant contamination issues and the cost to handle soil / fill from the extension will be better defined.

The Subsurface Investigation field activities included a geophysical survey, the advancement of six (6) soil borings, and the collection of twenty (20) soil samples for laboratory analysis.

FINDINGS

The findings of the Subsurface Investigation indicate the following:

• The geophysical survey soil boring locations were cleared of subsurface utilities and marked out with spray paint.

• The depth to groundwater beneath the Site was found to range approximately 5>10 ft bgs.

Groundwater at the Site is expected to flow in a southerly direction toward the nearest surface water body, the Hudson River, located approximately 0.5 mile west of the Site.

• The site is underlain by historic fill that consists of sandy silt with some brick, ash, wood and concrete based on the on>site soil borings advanced during this investigation. Bedrock was not encountered during the subsurface investigation.

• Soil sample laboratory analytical data indicated that no concentrations of VOCs, pesticides, herbicides and/or metals were detected exceeded the Restricted Use Soil Cleanup Objectives

(SCOs) for ‘industrial use’ (Part 375>6.8(b) – Track 2). Five (5) SVOCs compounds of benzo(a)anthracene; benzo(b)fluoranthene; benzo(a)pyrene; indeno(1,2,3>cd)pyrene; and dibenz(a,h)anthracene were detected at concentrations exceeding the Restricted Use Soil Cleanup http://www.hudsonvalley.va.gov/

Objectives (SCOs) for ‘industrial use’ (Part 375>6.8(b) – Track 2) in soil samples, SB>1A, SB>1B and SB>4A.

• Lead was detected at concentrations above Eastern USA background ranges two samples (SB>3A and SB>3B).

• A review of the subsurface soil sample analytical results for TCLP indicated that there were no detectable concentrations exceeding the EPA TCLP Regulatory Levels.

CONCLUSIONS AND RECOMMENDATIONS

Based on the results of the Subsurface Investigation, STV concludes the following:

• Visual observations, field screening and analysis of subsurface soil samples collected revealed that the Site is underlain by historic fill that consists of sandy silt with some brick, ash, wood and concrete based.

Based on the results of the Subsurface Investigation, STV recommends implementing the remediation measures listed below:

• No further action required.

• Any future work at Site requiring excavation and/or subsurface disturbances should be completed under the requirements of a Health and Safety and Excavation and Material Disposal Plan.

1.0 INTRODUCTION

1.1 Purpose

At the request of the United States Department of Veterans Affairs (VA), Office of Construction and

Facilities Management, STV Incorporated (STV) conducted a Subsurface Investigation on a parcel of land on the FDR Campus, Westchester County, 2094 Albany, Montrose, New York 10548 (hereinafter referred to as the “Site”). A Site Location Map is presented in Figure 1.

FDR Campus in Montrose is a part of the The VA Hudson Valley Health Care System which also includes the Castle Point Campus in Dutchess County and several community based clinics.

The property is identified as Parcel SBL: 05401600030010000000 on the Municipal Tax Parcel Map. It is located to the north of the hamlet of Crugers, to the east of Hudson River, to the south of Dutch Street and to the west of Albany Post Road.

The Site consists of a 44,000 square foot (SF) parcel situated on the northern end of the property. It consists of gravel to the east and a vegetative area to the west and is bounded by a chain link fence, streams and wooded area. Currently the property serves as a staging area for equipment, some vehicles and dumpsters. The Site location on the property is presented in Figure 2 (Site Aerial View Map).

This scope of work was prepared in response to existing stormwater line concerns at Site. It was concluded that routing the stormwater line through an area in the vicinity of the Area of Investigation

(AOI) that had reportedly received historic fill material, provided the most direct routing but posed a potential concern with managing potentially contaminated historic fill during excavation and construction of the stormwater line extension. As a first step, the current extent of any soil/ fill impacts along the projected alignment of the proposed stormwater extension would be assessed with a geophysical survey and soil program. Based on these findings, the probability of encountering significant contamination issues and the cost to handle soil / fill from the extension will be better defined.

2.0 DESCRIPTION OF PHASE II ESI FIELD ACTIVITIES

The Subsurface Investigation field activities were performed on March 7 and June 24, 2013. An aerial view showing the area of investigation is presented as Figure 2 and sampling locations as Figure 3.

Representative photographs of field investigation activities are attached in Appendix A.

The investigation was conducted in accordance with STV’s Scope of Work (SOW) dated November 21, 2013 and included the following:

• Geophysical survey of the Site to clear proposed soil boring locations;

• Advancement of six (6) soil borings and collection of 12 soil samples plus one (1) duplicate sample;

• Collection of six (6) soil composite samples and one (1) duplicate sample to 10 feet below ground surface (ft bgs.) for Hazardous Characteristics and Toxic Characteristic Leaching

Procedure (TCLP) metals; and

• Survey of each soil boring for potential landfill gases.

In general, the investigation was completed in accordance with the SOW. At two (2) soil borings, SB:5 and SB:6, refusal was encountered at 4:5 ft bgs. therefore multiple locations adjacent to the original location were drilled to achieve a depth of 10 ft bgs..

The deviations from SOWs did not impact STV’s ability to characterize the Site. The scope of the field activities and methods are described below.

2.1 Geophysical Survey

On:site geophysical survey was performed on March 7, 2013, by Diversified Geophysics, Inc. (DGI) of

New Hyde Park, New York, to verify that the proposed soil borings were clear of subsurface structures and/or utilities by surveying a 20:foot by 20:foot maximum area around each boring location.

The geophysical survey was conducted using Ground Penetrating Radar (GPR) data with Sensors and

Software 250 MHz NogginPlus SmartCart®; and a receiver of a Ridgid® SeekTech (SR:60) Pipe and

Cable Locator was used in a stand:alone mode (without the transmitter) to locate utilities emitting frequencies in the 60Hz range (active electric). The Ridgid® receiver was also used with a transmitter box (ST:33Q) in an attempt to trace water and drainage services. Anomalies identified from the geophysical survey are depicted in Figure 3 of the geophysical report which is provided in Appendix B.

2.2 Soil Investigation

Six (6) soil borings (SB:1 through SB:6) were advanced on June 24, 2013 by Aquifer Drilling and

Testing, Inc. (ADT) of Mineola, New York. The borings were advanced using a track:mounted

Geoprobe 6610 drill rig equipped with a 2:inch outside:diameter, 5:foot long stainless steel macrocore sampler lined with disposable acetate sleeves. The borings were placed at intervals of approximately 75 feet apart adjacent to the proposed stormwater extension. Each boring was extended to a depth of

VA Hudson Valley HCS

STV, INC. 5 3015409

approximately 7:10 ft bgs. to characterize soil/ fill to the maximum depth expected for the stormwater extension. The soil boring locations are presented on Figure 3.

All soil borings were completed under the supervision of an STV Environmental Scientist. Samples were screened and inspected for indications of contamination (e.g., staining, odors, etc.) and borings with a 4:

gas meter RAE Multimeter for volatile organic compounds (VOCs), Lower Explosive Limit (LEL), hydrogen sulfide (H2S) and carbon monoxide (CO). Geologic descriptions of the soil, boring and field screening results were recorded in field boring logs. A duplicate grab sample [REP072413 (1:3 ft bgs) was collected from soil boring SB:6 to correspond with soil sample SB:6A (2:4 ft bgs) and a composite duplicate sample [REP072413C (0:10 ft bgs.)] was collected from soil boring SB:6 to correspond with soil composite sample SB:6. Each soil sample collected was placed into pre:cleaned, laboratory:

prepared glass sample jars using clean and disposable one:time disposal scoops and with TerraCore sampler for VOCs. Care was taken to obtain representative soil samples. Sample jar threads were wiped clean of soil particles and the jars sealed with Teflon:lined screw closure lids. The sample jars were uniquely labeled to identify the sample number, project name, and the date and time of collection.

One (1) sample was collected from the zone impacted based on odors, staining, elevated PID readings, or presence of historic fill material; and a second sample was collected from the bottom of the boring.

Soil samples (SB:1A, SB:1B, SB:2A, SB:2B, SB:3A, SB:3B, SB:4A, SB:4B, SB:5A, SB:5B, SB:6A, SB:6B and REP062413) were analyzed for tentatively identified compounds (TCL) VOCs per United

States Environmental Protection Agency (EPA) Method 8260B, TCL semi:volatile organic compounds

(SVOCs) per EPA Method 8270C; polychlorinated biphenyls (PCB) per EPA Method 8082; pesticides per EPA Method 8081A; herbicides per EPA Method 8151A and Resource Conservation and Recovery

Act (RCRA) metals per EPA Method 6010B/7471A.

Soil samples (SB:1, SB:2, SB:3, SB:4, SB:5, SB:6, and REP062413C) were analyzed for the Code of

Federal Regulations, Title 40: Protection of Environment, Part 261, Subpart C ‘Characteristics of

Hazardous Waste’ (toxicity, corrosivity, reactivity and ignitability) per EPA Method

6010B/7470B/1030/9014/9034/9045C/EPA Moisture.

Soil samples were placed into insulated coolers with ice and submitted under standard chain:of:custody protocol to TestAmerica of Shelton, Connecticut, a New York State Department of Health (NYSDOH)

ELAP certified laboratory (New York Certification No. 10602). The laboratory analytical reports and the chain of custody forms are presented in Appendix C.

Upon completion of soil sampling, each boring was backfilled to near surface grade with sand.

3.0 DISCUSSION OF FINDINGS

This section presents a discussion of the findings of the Subsurface Investigation including geophysical survey results and soil sampling results. A summary of the laboratory analytical results is presented in

Tables 1 though 5. The complete laboratory analytical data packages are included in Appendix C.

3.1 Applicable Regulatory Standards

This subsection identifies the USEPA and NYCDEP regulatory standards and guidelines used to evaluate the results of the soil sampling. The standards and guidelines used to evaluate the specific data are described individually below.

3.1.1 Soil Cleanup Objectives (SCOs)

The Restricted Use (Track 2) SCOs found in 6 NYCRR 375/6.8(b), Remedial Program Soil Cleanup

Objectives for ‘Industrial Use’ are the appropriate standards for use in evaluating the results of the analyses of the Subsurface Investigation soil samples. The results of the metal analyses were also compared to the Eastern USA Background (E/BG) concentrations included in TAGM.

3.1.2 Toxic Characteristic Leaching Procedure (TCLP) for metals

The Code of Federal Regulations, Title 40/ Protection of Environment, Part 261, Subpart C

‘Characteristics of Hazardous Waste’ are the appropriate standards for use in evaluating the results of the analyses of the Subsurface Investigation soil samples. TCLP is one of the Federal EPA test methods that are used to characterize waste as either hazardous or non/hazardous for the purpose of disposal. The test does not measure total metal compounds content; rather, it measures the potential for the compound to seep or "leach" into groundwater if a waste is landfill disposed.

3.2 Geophysical Survey Findings

The geophysical survey was conducted at the Site to locate, trace and mark the presence of any subsurface utilities, documented or undocumented structures and/or anomalies within the areas of investigation (AOI’s), in advance of the boring program. Six (6) proposed sampling locations were investigated for obstructions and cleared for drilling. The geophysical survey identified the following:

• GPR data sets collected throughout the AOI did not reveal any linear target returns that could be interpreted as indication of the presence of storm drainage pipe.

• All proposed soil boring locations were cleared of subsurface utilities and marked out with spray paint.

Limitations were encountered during the survey due to the extremely disturbed, heterogeneous nature of the substrate (i.e. debris) and was a factor in the lack of interpretable data. A copy of the geophysical survey report is attached as Appendix B. The Survey Plan included in Appendix B depicts the areas investigated during the geophysical survey.

3.3 Soil Sampling Findings

3.3.1 Field Observations

Soil samples were screened continuously from the ground surface to the 7/10 ft bgs. Soil samples were field/screened with a photoionization detector (PID) of the miniRAE for VOCs and for visible evidence and olfactory observations of petroleum (or other chemical) impacts. Soils were logged using the

Burmeister Classification System and the Unified Soil Classification System. The soil borehole was screened for VOCs, LEL, H2S and CO.

The water table was encountered in the borings from a range of 5 ft bgs. at SB/1, SB/2 to 9/10 ft bgs. at

SB/4 and SB/5. Bedrock was not encountered.

The soil borings showed evidence of historic fill (brick, ash, food, concrete debris) but no evidence of staining, olfactory and/or PID readings were recorded. No recorded readings were observed for VOCs, LEL, H2S and CO in the soil boreholes.

A complete copy of the boring logs is presented in Appendix D.

3.3.2 Volatile Organic Compounds (VOC) in Soil

A review of the soil sample analytical results indicated that VOCs were detected in all thirteen (VOCs) on the Site. No samples had concentrations exceeding the Restricted Use Soil Cleanup Objectives

(SCOs) for ‘industrial use’ (Part 375/6.8(b) – Track 2).

The analytical data summary tables for VOCs in soil are presented in Table 1 and the analytical data reports are provided in Appendix C.

3.3.3 Semi-Volatile Organic Compounds (SVOC) in Soil

A review of the soil sample analytical results indicated detections of SVOCs in twelve (12) of the thirteen (13) on the Site. Five (5) compounds of benzo(a)anthracene; benzo(b)fluoranthene;

benzo(a)pyrene; indeno(1,2,3/cd)pyrene; and dibenz(a,h)anthracene were detected at concentrations exceeding the Restricted Use Soil Cleanup Objectives (SCOs) for ‘industrial use’ (Part 375/6.8(b) –

Track 2) in soil samples, SB/1A, SB/1B and SB/4A.

The analytical data summary table of SVOCs detected in soil is presented in Table 2 and the laboratory data reports are provided in Appendix C.

3.3.4 Pesticides / Herbicides / PCBs in Soil

The laboratory analytical results indicated no detectable concentrations of pesticides, herbicides or PCBs in the soil samples.

VA Hudson Valley HCS

STV, INC. 9 3015409

The analytical data summary table of pesticides, herbicides and PCBs is presented in Table 3 and the laboratory data report is provided in Appendix C.

3.3.5 RCRA Metals in Soil

A review of the analytical results for RCRA metals indicated that all thirteen (13) soil samples had detectable concentrations but none exceeding Restricted Use Soil Cleanup Objectives (SCOs) for

‘industrial use’ (Part 375/6.8(b) – Track 2). Lead was detected at concentrations above Eastern USA background ranges in two (2) soil samples (SB/3A and SB/3B).

The analytical data summary of metals in soil is presented in Table 4 and the analytical data reports are provided in Appendix C.

3.3.6 TCLP Metals in Soil

A review of the subsurface soil sample analytical results indicated that there were no detectable concentrations exceeding the EPA TCLP Regulatory Levels.

The analytical data summary of TCLP metals in soil is presented in Table 5 and the analytical data reports are provided in Appendix C.

3.4 Summary of Findings

STV performed a Subsurface Investigation consisting of a geophysical survey, advancement of six (6) soil borings, and collection of twenty (20) soil samples for laboratory analysis adjacent to the proposed stormwater extension line. The results of the Subsurface Investigation indicate the following:

• The geophysical survey soil boring locations were cleared of subsurface utilities and marked out with spray paint.

• The depth to groundwater beneath the Site was found to range approximately 5/10 ft bgs.

Groundwater at the Site is expected to flow in a westerly or southerly direction toward the nearest surface water body, the Hudson River, located approximately 0.5 mile west of the Site.

• The site is underlain by historic fill that consists of sandy silt with some brick, ash, wood and concrete based on the on/site soil borings advanced during this investigation. Bedrock was not encountered during the subsurface investigation.

• No PID, LEL, H2S and/or Co readings were observed.

• Soil sample laboratory analytical data indicated that no concentrations of VOCs, pesticides, herbicides and/or metals were detected exceeding the Restricted Use Soil Cleanup Objectives

(SCOs) for ‘industrial use’ (Part 375/6.8(b) – Track 2). Five (5) SVOCs compounds of benzo(a)anthracene; benzo(b)fluoranthene; benzo(a)pyrene; indeno(1,2,3/cd)pyrene; and dibenz(a,h)anthracene were detected at concentrations exceeding the Restricted Use Soil Cleanup

Objectives (SCOs) for ‘industrial use’ (Part 375/6.8(b) – Track 2) in soil samples, SB/1A, SB/1B and SB/4A.

• Lead was detected at concentrations above Eastern USA background ranges two samples (SB/3A and SB/3B).
