DRINKING WATER SAMPLING SUMMARY REPORT BRISTOL RESIDENCE TOWNSHEND, VT VT DEC #89-0430 Prepared for: Alex Geller VT DEC - SMS 103 South Main Street Waterbury VT 05671-0404 ECS Project No.04-218408 December 28, 2012

Alex Geller December 28, 2012 Vermont Department of Environmental Conservation Project No. 04-218408.00 Sites Management Section 103 South Main Street Waterbury, VT 05671-0404 RE: Drinking Water and Groundwater Sampling Summary Report Bristol Residence

Townshend, VT 05353 VT DEC# 93-1376

Dear Mr. Geller: Environmental Compliance Services, Inc. (ECS) is pleased to submit the following summary report of the drinking water and groundwater sampling conducted in Townshend, Vermont. Drinking water wells and groundwater were sampled to investigate potential petroleum impacts to groundwater related to the 1989 gasoline release at 1977 Vermont Route 30. ECS performed this work at the request of the Vermont Department of Environmental Conservation (VT DEC) in a correspondence dated November 19, 2012. A Site Locus Map is provided as Figure 1. A Site Plan showing sample locations is included as Figure 2. Site Background In July 1989, Jay Bristol of 1978 Vermont Route 30 (Map 9, Lot 137) contacted the Vermont Agency of Natural Resources Hazardous Materials Management Division (HMMD) due to a strong gasoline odor emanating from the drinking water at his residence. On August 22, 1989, drinking water samples were collected from Mr. Bristol’s residential water supply, which confirmed the presence of dissolved gasoline constituents. Based on the proximity of his home to (former) Bischoff’s Auto Sales (1977 Vermont Route 30, Map 9, Lot 108), the source of the gasoline was suspected to be abandoned underground storage tanks (USTs) situated on Bischoff’s property. HMMD approved monthly drinking water sampling at Mr. Bristol’s residence. In September 1989, the drinking water sampling program was expanded to 16 surrounding properties (which included residential, commercial and municipal properties), nine of which were determined to have gasoline impacted water supply wells. Based on the findings of the preliminary investigation, HMMD determined that the two abandoned USTs located at Bischoff’s Auto Sales and owned by J.L.F Enterprises, Inc. were the source of the dissolved gasoline impacts. In October 1989, ten drinking water supplies were tested for the presence of gasoline related constituents. A carbon treatment system was added to the Bristol water supply, which was operated until August 1994 when dissolved concentrations of gasoline constituents dropped to below regulatory action levels. The remaining wells were found to be impacted with dissolved gasoline constituents at concentrations below the established

Drinking Water Sampling Summary Report December 28, 2012 Bristol Residence 04-218408 Townshend, Vermont Page 2 Department of Health standards. Due to the presence of these dissolved gasoline constituents, HMMD supplied bottled drinking water to affected residential, municipal, and commercial properties. In February 1990, Tri-S began UST decommissioning activities. The UST fills were uncovered, the tanks pumped, and steam cleaned on February 1, 1990. An attempt to excavate the USTs was made on February 2, 1990; however, due to site conditions and an impending storm, excavation activities were terminated. Four monitoring wells were installed using an air rotary drill. The monitoring wells were sampled on February 26, 1990 for volatile organic compounds (VOCs) via Method 602 and methyl tertiary-butyl ether (MtBE) analysis. Laboratory analytical results confirmed the presence of dissolved gasoline constituents in downgradient monitoring wells and the absence of impacts in the upgradient monitoring well, which confirmed that the USTs at Bischoff’s Auto Sales was the source of contamination. Groundwater was determined to flow to the east, toward the private supply well at the Bristol residence and Mill Brook. One 3,000-gallon and one 1,000-gallon single wall steel UST were removed from the Bischoff’s Auto Sales property in August 1990. Both USTs were found to be compromised with several holes observed in the base and sidewalls. Approximately 50 cubic yards of gasoline impacted soil was excavated and stockpiled at the Jamaica AOT garage during the UST removal. The well at the Bristol Residence, located at 1978 Vermont Route 30 (Map 9, Lot 137), was reinstalled between December 11 and 18, 1990. The former well was decommissioned using grout. The well at the former Steiner Residence (currently the Tarbell property) which also served the Townshend Library and Post Office, was reinstalled and the abandoned well was filled with grout. Based on available documentation it is unclear if the newly installed well still serves these municipal properties; however, as additional well installation information has not been located, it is presumed that these three properties continue to share a well. Leggette, Brashears, and Graham, Inc. (LBG) of Nashua, New Hampshire conducted a groundwater sampling round on May 10, 1994. LBG noted that the concentration of VOCs detected during the May 1994 groundwater sampling event demonstrated a significant reduction in dissolved phase impacts; however, monitoring wells BAS-1, BAS-4, and BAS-5 were still impacted above the regulatory standards. LBG opined that the dissolved phase gasoline plume had advanced downgradient, to the east of the source area. LBG recommended continued monitoring of groundwater and private supply wells. Petroleum odors in the drinking water have been recurrent at the Bristol Residence (1978 Vermont Route 30). In 2001 petroleum odors were detected in the drinking water. A sample was collected; however, due to a large amount of headspace the sample data has questionable validity. No gasoline constituents were detected within the sample. The VT DEC project manager supplied additional containers to resample; however, no subsequent samples were submitted by the property owner. In 2006, there was a recurrence of the petroleum odors and VT DEC supplied sample collection containers. No sample has been received from the property owner. As of 2012, three properties continue to receive bottled water from VT DEC under a contract with Hidden Springs. These properties are the Bristol Residence (1978 Vermont Route 30), the Zully Residence (1988 Vermont Route 30 – currently a two apartment rental), and the Townshend Post Office (1955 Vermont Route 30).

Procedure ECS conducted drinking water sampling at properties in Townshend over a two day period on December 11 and 12, 2012. In order to obtain a representative sample, all samples were collected in accordance with EPA Method 524.2. Samples were collected either from interior taps in the bathroom or kitchen when no treatment system was present and at pre-treatment access points for those properties with active treatment systems. The aerator was removed (where present) and the tap was allowed to run for approximately ten minutes, until the water temperature stabilized. Three 40 milliliter (mL) 1:1 hydrochloric acid (HCl) preserved volatile organic analysis (VOA) containers were filled at each sampling location and placed on ice. Samples were maintained at 4°C (± 2°C) until relinquished to the laboratory under chain-of-custody. ECS conducted groundwater sampling in accordance with EPA Method 8260. A minimum of three well volumes were purged from each monitoring well sampled using a dedicated polyethylene bailer prior to sample collection. Three 40 mL 1:1 HCl preserved VOA containers were filled at each sampling location and placed on ice. Samples were maintained at 4°C (± 2°C) until relinquished to the laboratory under chain-of-custody. The sample batch was submitted with a laboratory prepared trip blank.

Sampling Locations Sampling locations were selected based on laboratory data collected in Townshend to date. Potentially impacted properties were contacted by telephone prior to the December 11, 2012 sampling event. Letters were sent to those properties for which a telephone number could not be located. One property owner was not available on December 11, 2012, so the sample from the location was collected on December 12, 2012. Table 1 below lists the properties sampled on each date.

Drinking Water Sampling Summary Report December 28, 2012 Bristol Residence 04-218408 Townshend, Vermont Page 4 Drinking Water Sampling Results Drinking water samples collected from 1955 VT Route 30 (Townshend Post Office), 1968 VT Route 30 (Masonic Temple), 1971 VT Route 30 (Townshend Public Library), 1988 VT Route 30 (Former Zully Residence), 2006 VT Route 30 (Town Hall), and 2111 VT Route 30 (Former Law Offices) did not contain any VOC analytes above the laboratory detection limit. The drinking water sample collected from 1978 VT Route 30 (Bristol Residence) contained a low level of MtBE; 0.5 micrograms per liter (µg/L). This concentration is well below the Preventive Action Level of 20µ/L and the Enforcement Standard of 40µg/L. The drinking water sample collected from 2042 VT Route 30 (Leland and Gray Union Middle and High School) contained 56.4µg/L of acetone and 2.73µg/L of isopropylbenzene. Similar concentrations of acetone (72.5µg/L) and isopropylbenzene (1.56µg/L) were also observed in the Trip Blank. The concentrations of acetone do not exceed either the Preventive Action Level (350.0µg/L) or Enforcement Standard (700.0 µg/L). Vermont does not have an established standard for isopropylbenzene. Acetone and isopropylbenzene are common laboratory contaminants and observed concentrations may be laboratory artifacts as opposed to contamination present within the aquifer. No other VOC compounds were detected above the laboratory method detection limit. Drinking water analytical results are summarized in Table 1. Groundwater Sampling Results Groundwater samples were collected from monitoring wells BAS-1, BAS-2, BAS-4, BAS-5, and BAS-6. Monitoring well BAS-7 was obstructed and could not be sampled. Monitoring wells BAS-3, BAS-8, and BAS-9 could not be located. Monitoring wells BAS-3 and BAS-9 appear to have been paved over, while monitoring well BAS-8 was last sampled prior to 1994 and is likely destroyed. No VOC analytes were detected above the laboratory reported detection limit in any groundwater samples collected. Based on the absence of detectable VOCs within the groundwater samples, residual gasoline impacts appear to have attenuated within the overburden aquifer. Groundwater analytical results are summarized in Table 2. The laboratory case narrative was reviewed for non-conformances and issues relating to quality control samples and/or sample analysis/matrix. Several non-conformances were noted; however, the non-conformances were not of sufficient quality to invalidate the data. Recommendations Based on the current laboratory data, ECS opines that residual impacts from the 1989 gasoline release have attenuated within the overburden aquifer and persist at low levels within the bedrock aquifer, which supplies drinking water to properties in the vicinity of the release area. ECS recommends decommissioning on- and off-site monitoring wells due to the absence of VOCs detected within groundwater samples collected from the overburden aquifer. An additional drinking water sampling event should be conducted at those properties downgradient of the gasoline release, including 1968 VT Route 30 (Masonic Temple), 1978 VT Route 30 (Bristol Residence), 1988 VT Route 30 (Former Zully Residence), 2006 VT Route 30 (Town Hall), and 2042 VT Route 30 (Leland and Gray Union Middle and High School), to confirm the presence or absence of residual gasoline impacts. Based on the results of the additional drinking water sampling event, a sampling schedule (either annually or biannually) will be developed if warranted.

Laboratory Control Sample (LCS): A known matrix spiked with compound(s) representative of the target analytes, which is used to

document laboratory performance.

Matrix Duplicate: An intra-laboratory split sample which is used to document the precision of a method in a given sample matrix.

Matrix Spike: An aliquot of a sample spiked with a known concentration of target analyte(s). The spiking occurs prior to sample

preparation and analysis. A matrix spike is used to document the bias of a method in a given sample matrix.

Method Blank: An analyte-free matrix to which all reagents are added in the same volumes or proportions as used in sample

processing. The method blank should be carried through the complete sample preparation and analytical procedure. The method blank

is used to document contamination resulting from the analytical process.

Method Detection Limit (MDL): The minimum concentration of a substance that can be measured and reported with 99% confidence

that the analyte concentration is greater than zero and is determined from analysis of a sample in a given matrix type containing the

analyte.

Reportable Detection Limit (RDL): The lowest concentration that can be reliably achieved within specified limits of precision and

accuracy during routine laboratory operating conditions. For many analytes the RDL analyte concentration is selected as the lowest

non-zero standard in the calibration curve. While the RDL is approximately 5 to 10 times the MDL, the RDL for each sample takes

into account the sample volume/weight, extract/digestate volume, cleanup procedures and, if applicable, dry weight correction. Sample

RDLs are highly matrix-dependent.

Surrogate: An organic compound which is similar to the target analyte(s) in chemical composition and behavior in the analytical

process, but which is not normally found in environmental samples. These compounds are spiked into all blanks, standards, and

samples prior to analysis. Percent recoveries are calculated for each surrogate.

Continuing Calibration Verification: The calibration relationship established during the initial calibration must be verified at periodic

intervals. Concentrations, intervals, and criteria are method specific.
