KLEINFELD ER On November 21, 1996, the farmhouse domestic well was sampled by Kleinfelder as a part of a property transfer's environmental investigation. The water sample obtained was analyzed by EPA Methods 624, 625, 632, and 619. Additionally, the water sample was analyzed for CAM 17 Metals, and some general mineral and drinking water analytes. The sample did not contain any of the organics for which it was tested. The sample did contain 440 mg/L bicarbonate alkalinity, 190 mg/L chloride, 100 mg/L nitrates, 41 mg/L sulfate, 890 mg/L Total Dissolved Solids, 0.43 mg/L barium, 0.010 mg/L zinc, 1,500 µmhos/cm Specific Conductance. The water sample also contained very low (and insignificant) concentrations of some other metals and minerals. The results of the sampling were detailed in Kleinfelder's report dated February 24, 1997 titled "Groundwater Sampling and Analysis (Phase I ESA Recommendation Number 3)....". Since that time the well pump has been removed, and the well has been abandoned under PHS/EHD permit. In December 1996. borings were advanced in the septic systems and former UST areas. Benzene, toluene, ethylbenzene, and total xylenes (BTEX), MTBE, and Total Petroleum Hydrocarbons as Rclerenced to Gasoline (TPH-G) was not detected in any of the soil samples analyzed from the former UST arca. the former fuel dispenser area, and the former fuel pipeline area. However, 0.51 f1g/L toluene (laboratory reporting limit was 0.50 pg/L) was detected in a Hydropunch groundwater sample obtained from Boring 2-2 (Backfilled UST Excavation). Extractable hydrocarbons, ethylene glycol, industrial solvents, organochlorine pesticides, PCBs, and chlorinated herbicides were not detected in any of the soil samples obtained from the borings advanced adjacent to the actual "daylighted" septic systems' components. However, ethylene glycol was detected in the Hydropunch groundwater sample obtained from the borings adjacent/downgradient to the shop septic tank and the shop leachfield at concentrations of 17 and 14 mg/L respectively. Additionally. Unidentified Extractable Hydrocarbons (Cto to Cao) was detected in the Hydropunch 11-01indwater sample from the soil boring located adjacent/downgradient to the shop leachfield at a concentration of 330 Itg/L. The results of the soil and groundwater sampling were detailed in Kleinfelder's February 24, 1997 report titled "Limited Phase 11 Soil and Groundwater Assessment, Farmhouse Area....". While in the process of trying to obtain regulatory closure on this area, it was recommended that additional borings be advanced and both water and soil be sampled for BTEX, TPH-G and Oxygenates (gasoline additives). The borings advanced in the area of the former UST were advanced under the permit for the work conducted in December 1996 and with verbal approval of Ron Rowe, R.E.H.S. of PHS/EHD. The results of the sampling and subsequent chemical analysis are detailed in this report as follows. 20-3978-01.W35/2017IZ491 Page No. 2 of 7 Copyright 1997. Kleinl'clder. Inc. October 4. 1997
