On October 4,2007, Wagner's Construction (Wagner's) mobilized to Ms. Eleanor Vance's property to purge, cut, clean, and remove one 2,000-gallon #2 fuel oil underground storage tank (UST #001). The property is located at 98 Webster Hill Road, in Danville, Vermont. Wagner's also performed an environmental site assessment for the tank removal. Please refer to Mr. Wagner's UST Closure report, dated October 1 5fi, for more information on tank removal and site assessment activities. Because contamination was found in the soils of the excavation area, Wagner's recommended EPSVT perform any additional assessment/remedial work to be done at the Vance property in relation to UST #001.

With approval from both you and the Vermont Department of Environmental Conservation (VDEC), EPSVT coordinated and supervised the installation of five groundwater monitoring wells in an array around the former tank grave on January 16,2008. On this same site visit, EPSVT collected two drilled well samples from the closest wells to the Vance property. EPSVT performed a full groundwater monitoring and sampling event and site survey on January 2gth. The results of this work are presented in the following sections.

Soil Borinrrs and Monitoring Well Installation To assess the degree and extent of subsurface contamination, EPSVT, in conjunction with the Verterre Group of Colchester, Vermont (Vertter), advanced five soil borings via Geoprobe at locations identified as MW-1 through MW-5 on Figure 2. These borings were performed on January 16,2008. As the borings were advanced, soils were descriptively logged and assayed for volatile organic compounds (VOCs) via the bag headspace method utilizing a properly calibrated 10.6 eV photoionization detector (PID). Soil screening detected the presence of VOCs above background (<0.1 part per million [ppm]) in the tank grave boring. Detailed monitoring well logs are presented as Appendix A.

Boring 1 (MW-1) was advanced approximately sixty feet northwest of the former UST and had no VOC detections above background. Boring 2 (MW-2) was advanced approximately thirty feet northeast of the former UST and had no VOC detections above background. Boring 3

Vance Property, SMS Site #: 2007-3726 98 Webster Hill Road, Danville, Vermont

Site Investigation Report March 10,2008

(MW-3) was advanced twenty-five feet south of the former UST and had a peak VOC reading of 0.4 pprn between and eight feet below grade. Boring 4 (MW-4) was advanced approximately sixty feet south of the former UST location and had a peak VOC reading of 0.3 pprn at between four and eight feet below grade. Boring 5 (MW-5) was advanced in the tank grave and had a peak VOC reading of 301.7 pprn between eight and ten feet below grade. One-inch diameter sch. 40 PVC monitoring wells were installed in each boring upon completion. All five wells were properly developed following installation, and the following notes were taken:

The monitoring wells were installed to depths ranging from eight to ten feet below grade and were constructed of 0.010" slot, 1" diameter PVC well screen, solid riser, sand parts, bentonite seals, locking expansion plugs, and protective roadboxes set flush to grade;

VOC detections in the borings of MWs 1-4 were all very low and no hydrocarbon odors were noted in any of these soils. A peak VOC detection of 301.7 pprn with petroleum staining and odors were noted between eight and ten feet in the MW-5 boring;

Soils observed were predominantly gravel until sand and silt were encountered around four feet below grade. Bedrock was not encountered; and

Saturated soils indicating a shallow groundwater table were encountered in each well at between six and eight feet below ground surface.

While onsite on January 1 6th, EPSVT screened the indoor ambient air of the Vance residence and no detections above background ( ~ 0 . 1 ppm) were noted. The comprehensive groundwater monitoring and sampling event was performed on January 29,2008. Following the groundwater monitoring and sampling event, EPSVT shot a Site survey to create an accurate base map (Figure 2) with well top-of-casing elevations so that groundwater flow and gradient could be determined.

Groundwater Elevations During the January 29th event, depth-to-water measurements were taken via Solinst interface probe, which is capable of measuring free product or water accurate to 0.01-foot. Free product was not encountered in any of the monitoring wells, and groundwater was found at between 4.47 and 6.02 feet below the five top of casings. The bailer in MW-4 was frozen; therefore, neither a groundwater elevation nor water sample was collected during this Site visit. Groundwater level data was converted to relative groundwater elevation based on well top-of-casing elevations. A summary of the groundwater elevation data is presented as Table 1 and groundwater contours and flow direction are depicted on Figure 2. As measured on January 29&, groundwater flow at this Site is generally to the southeast at an average gradient of 0.075 feet per foot. The relatively steep groundwater gradient corresponds with the hillside location of the Site.

Photoionization Detector Well Headspace Monitoring Prior to collecting depth-to-water measurements, EPSVT assayed the well headspace gasses for concentrations of VOCs. A properly calibrated 10.6 eV PID was used, and the data are presented in Table 2. Very low levels of VOCs were detected in every well on Site, with a low of 0.2 pprn in MW-5 and a high of 4.1 pprn in MW-1. In the absence of substantially elevated



readings in any of the wells, EPSVT finds that subsurface contamination is not volatizing at a significant rate through these soils.

Water Qualitv Samplin EPSVT collected a sampL from the two neighboring drilled bedrock wells on January 1 6 ~ ~ from the taps of the Gadapee and Munkitchick properties, which were sent, on ice, to Green Mountain Laboratories Inc. (GML) of Montpelier, Vermont, for analysis via EPA Method 524.2. The Gadapee well is located approximately 700 feet west and the Munkithick well is located approximately 1,000 feet northwest of the former UST. The Gadapee drilled well had detections of chloromenthane (0.79 pg/L), 1,4-Dichlorobenzene (1.1 pg/L), methylene chloride (0.7 1 pg/L), and methyl-tert-butyl ether( 1.1 pg/L). The Munkithick drilled well had detections of chloromethane (0.65 pglL), 1,4-Dichlorobenzene (1 .l pg/L), and methylene chloride (0.61 pg/L). A copy of the laboratory analytical reports is included as Appendix B.

Though anomalous, these detections are well below the PALS set for Vermont potable water, which is tied to the Environmental Protection Agency's maximum contaminant levels, except for methylene chloride, which has a PAL of 0.5 pg/L. Methylene chloride was historically used as an industrial solvent and as a paint stripper. EPSVT believes this contaminant is not related to the #2 fuel oil release that occurred at the Vance property; however, a copy of the laboratory report and an information sheet from the Department of Heath and Human Services has been sent to the drilled well owners for their awareness.

On January 2 9 ~ , after the groundwater monitoring, EPSVT collected samples from four of the five on-site monitoring wells using appropriate methods and dedicated materials. MW-4 was not accessible. The samples were brought on ice, along with a trip blank, to GML for analysis via EPA Methods 8260 and 801 5 for VOCs and total petroleum hydrocarbons, diesel range organics (TPH DRO). A summary of the laboratory results is presented as Table 3 and a copy of the laboratory analytical reports is attached as Appendix B.

There were no detections of any target analytes above the laboratory limits in the trip blank or the MWs 1 and 2 samples. MW-3 had a low detection of toluene at 2.3 pg/L. MW-5 had contaminant detections of sec-butylbenzene at 4.2 pg/L, isopropylbenzene at 2.2 pg/L, p- Isopropyltoluene at 5.2 pg/L, n-propylbenzene at 4.3 pg/L, and 1,3,5-TMB at 2.2 pg/L. All of these concentrations are below the Vermont Groundwater Quality Enforcement Standards (GQES). For the Method 8015 analyses, MW-1 had a TPH detection of 2.2 mg/L. MWs 2 and 3 both had a detection of 2.3 mg/L, and MW-5 had a detection of 18 mg/L.

These results show minimal contamination in the local groundwater at the Vance property. The two wells that showed low detections above laboratory detection limits are the tank grave well and one well downgradient of the former tank location.

Sensitive Receptor Survev A sensitive receptor survey was conducted within a one-half mile radius of this release. The Vance property is located in a low-density residential area and appears to have historically been agriculture and forested land (see Figure 3). According to the information from the Vermont



ANR Well Drillers Reports (http://www.anr.state.vt.us/site/html/maps.htm) and general site observations there are 15 private water supply wells within the one-half mile radius. The average well depth is 227 feet with an average overburden thickness of 30 feet. It has been reported by Richard Vance that the Eleanor Vance property is supplied by town water and EPSVT did not observe any well casings while onsite.

The closest mapped private water supply well is located approximately 700 feet west of the Vance property and is owned by Larry and Dianne Gadapee. This well is reported to be 173 feet deep with an overburden thickness of 62 feet. The Gadapees have been notified of the UST release and have given permission to EPSVT to collect a sample from their tap. The next closest private well is located approximately 1,000 feet north northwest of the Vance property. This well is owned by Allen Munkithick and is reported to be 180 feet deep with an overburden thickness of 67 feet.

Information from the Vermont ANR Management Site Locator (http://www.anr.state.vt.us/site/htmVmaps.htm) reveals there are no Class I1 wetlands located within the survey radius. There are no hazardous waste sites or generators located within the one-half mile radius. There are no registered underground storage tank facilities within the survey area.

A brook named Water Andric is located approximately 3 15 feet northwest of the former UST. There are three unnamed streams also located within the survey radius. The closest one is located approximately 75 feet northeast of the former UST and the other two are located approximately 3 15 feet northwest and 2,100 feet southwest of the former UST. According to the Vermont Geological Survey's database, the surficial material consists of glacial till and the bedrock consists of calcareous granulites and schists, which are composed of quartz, calcite, muscovite, and biotite. Bedrock was not observed during well installation or reported during excavation activities by Wagner's.

The identified sensitive receptors that are currently impacted by contamination from this release are the soils and groundwater below and adjacent to the former UST. The Water Andric located within 100 feet of the former UST is threatened; however, due to the minimal impact at this Site, EPSVT believes it to be minimally threatened. It has not been impacted to date.

Conclusions and Recommendations Based on the data collected, the following conclusions are made:

Subsurface contamination at the Vance property was caused by the release of an undetermined amount of fuel oil fkom a leaking UST. The timeline of the release is unknown. The UST was properly cleaned, removed, and disposed of by Wagner's on October 4,2007;

Groundwater monitoring wells have been installed in an array around the former UST area, and have been sampled and analyzed for petroleum related constituents. No detections

encountered in the MW-5 sample, with a low toluene detection in MW-3. A TPH detection of 18 mg/L was noted in MW-5 and low TPH detections were noted in MWs 1-3. No other detections above laboratory limits were noted in any of the wells. EPSVT believes that the current array of monitoring wells adequately defines subsurface contamination at this Site;

The sensitive receptors that are currently impacted by this release include the soils and groundwater in the vicinity of the former UST; and

The extent of impact is confined to the property and the degree is minimal.

Based on these conclusions, EPSVT makes the following recommendations:

1. Confirmatory Groundwater Monitoring and Sampling and Air Monitoring

EPSVT recommends that a second groundwater monitoring and sampling event be conducted approximately six months from the initial monitoring and sampling event. Samples will be collected from all five groundwater monitoring wells and the two neighboring private water supply wells using standard procedures and will be sent, along with a trip blank, for analysis via EPA Method 8021B. A groundwater elevation and water quality summary map will be generated. EPSVT will screen the indoor ambient air of the residence on this Site visit via properly calibrated 10.6 eV PID; and

2. Summary Report Generation

Following receipt of the laboratory analytical results, EPSVT will generate and submit a water quality update report detailing the results of the second groundwater monitoring and sampling event. Conclusions will be drawn based on all available data and appropriate recommendations will be made for any further work at the Vance property. If contamination levels remain stable or decline, EPSVT will recommend well closure and request a Site Management Activities Completed designation.

A scope of work and cost estimate to perform these two tasks is attached as Appendix C, and EPSVT looks forward to proceeding with this plan with your approval and that of the Vermont DEC.

RE: Appendix C: Scope of Work and Cost Estimate Vance Property - 98 Webster Hill Road, Danville, Vermont SMS Site # - 2007-3726

Dear Mr. Seder:

EPSVT is pleased to present the following quotation for services to be performed at the Vance property in Danville, Vermont. EPSVT will provide all labor, materials and equipment necessary to perfom the following scope of work:

SCOPE OF WORK

1. Groundwater Monitoring and Sampling EPSVT will perform a second full groundwater monitoring and sampling event to continue to analyze potential petroleum contamination in the local groundwater surrounding the source area. EPSVT will also screen each well headspace for VOCs utilizing a properly calibrated 10.6 eV PID and measure depth to water to generate a groundwater flow map. EPSVT will collect water quality samples from all monitoring wells, along with a trip blank, which will be analyzed via EPA method 8021B for VOCs including BTEX, 1,3,5 & 1,2,4 TMB, naphthalene, MTBE, 1,2 DCE, and EDB. A new base map will be generated to determine groundwater contours and flow direction; and

2. Summary Letter Generation Upon receipt of laboratory analytical reports for the water samples, EPSVT will generate and submit a report detailing the sample collection and analytical reports. Conclusions will be drawn and appropriate recommendations will be made for any further work necessary at the Vance property.

The costs for implementing this work plan are as follows:

TASK 1 - Groundwater Monitoring and Sampling;
