On 9/22/08, CS issued a letter to Samantha Ange of Chickaloon Village in follow-up to conversations on 8/18 and 19/2008 with CS and DEC's review of your consultant Tutka’s report “Site Cleanup Report Chickaloon Village Housing Fuel Spill” dated 8/10/2007. During those conversations, Samantha requested comments regarding the report as well as whether further work is needed to occur and whether or not a risk is posed to any occupants of the residence on site as the result of the remaining contamination. The report noted that about 90 cubic yards (cy) of petroleum hydrocarbon contaminated soil was excavated from the release of the home heating tank and placed into a landfarmed cell (cell) about 21 feet from the northeast corner of the residence on the property. The cell measured about 34 feet square and the soil was placed onto a liner and a cover consisting of per Mr. Guyer on September 18, 2008 of plastic sheeting over the contaminated soil. The release was estimated between 250 and 300 gallons of heating fuel oil. On August 19, Samantha noted that the residence consists of a single family dwelling that has a block foundation and a crawl space. The report noted that excavation was to the maximum depth of the excavator which was about 16 feet below ground surface (bgs). Mr. Guyer noted on September 18, that field screening measurements, and as shown on Table 1 of the report, indicates that contamination to at least 3 ft. bgs was removed from the sidewall of the excavation closest to the residence but that high contamination remained in the bottom of the pit and on the south and east sidewalls of the excavation (i.e., on the south sidewall up to 488 ppmv was detected and on the east sidewall up to 525 ppmv detected and at the bottom of the pit 408 ppmv was measured where a sample collected showed 1,650 mg/kg DRO). Confirmation soils in the excavation pit showed that at the bottom of the pit remained contamination above applicable 18 AAC 75.341 Method Two cleanup levels, i.e., diesel range organics (DRO) at 1,650 mg/kg (Method 2 cleanup level is 250 mg/kg), gasoline range organics (GRO) at 406 mg/kg (Method 2 cleanup level is 300 mg/kg), and benzene at 0.0352 mg/kg (Method 2 cleanup level is 0.02 mg/kg). The above noted constituents of concern were also detected in the cell above their respective cleanup levels (i.e., DRO up to 2,710 mg/kg, GRO up to 904 mg/kg, and benzene up to 0.101 mg/kg. The report inferred that Chickaloon Village Family Housing personnel would till the soil in the cell and perhaps add fertilize and/or water to the mixture to enhance natural attenuation. During our conversations, Samantha noted that personnel periodically till the soils during the past two summers. The report states that the nearest drinking water well on site is the private well on the property which is about 75 feet to the southwest of the former heating tank location/release area. The report also provided a well log which noted that well was drilled to a depth of 195 feet bgs and had a measured static water level of 147 feet bgs, indicating a possible upward gradient in the aquifer. The report also noted that the groundwater flow direction is unknown. Mr. Guyer noted on August 26, 2008 that information indicates that on a regional basis, groundwater flows to the south southwest, i.e., from the release area towards the private drinking water well on site. In its letter, DEC requested a workplan to sample the drinking water well, characterize the remaining contamination after excavation and a CSM. DEC also requesting information on the status of the cell.

Update or Other Action |
In a telephone conversation on 9/22/08, Samantha Ange requested a response from CS whether the contamination at the subject residence 17993 may pose a risk to future occupants of a proposed subdivision located on the adjoining 40 acre parcel located as near as 690 feet to the east of the subject residence/release. Between 9/22 and 10/8, Ms. Ange provided figures of the location of the residence in perspective to the proposed development. Based on information that Ms. Ange provided and Keith Guyer of Tutka that regional information shows groundwater flow was to the south/southwest of the residence, CS informed Ms. Ange in a 10/8/08 email that the only exposure pathway that could cause an impact to occupants to the proposed development from the release at residence 17993 was through ingestion of contaminated groundwater - however, it is not known even whether groundwater is contaminated because of the release. Further, groundwater in the area of the release is between 147 to 220 ft. below ground surface, and the subject residence is cross gradient and a bit downgradient from the release to the proposed development. Thus, there is little likelihood that contamination from the release will impact the proposed development. CS also informated Ms. Ange that to absolutely determine whether this risk may exist the association could delieate the release and demonstrate whether it has or may in the future reach groundwater and/or when drinking water wells are designed the association's engineer determine whether any drawdown from the new wells could draw water from the area of residence 17993. |
