On December 19, 20, and 21, 2022, PM completed subsurface assessment activities at the subject property that included conducting a GPR survey to identify the location of the former septic field and to clear the borings of private subsurface utilities, advancement of 13 soil borings (SB-1 through SB-13), installation of 12 temporary monitoring wells (TMW-1 through TMW-7 and TMW 9 through TMW-13) to a maximum depth of 30 feet bgs, and collection of soil and groundwater samples for laboratory analysis of volatile organic compounds (VOCs), polynuclear aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs), and Resource Conservation and Recovery Act (RCRA) 8 - Metals (arsenic, barium, cadmium, chromium , lead, mercury, selenium, and silver), or some combination thereof.
No VOCs, PAHs, or PCBs were detected in the soil samples analyzed from the subject property at concentrations above the laboratory reporting limits (RLs) or applicable screening criteria. Arsenic was detected above the EPA Regional Screening Levels (RSLs) for commercial soils; however, the concentrations and distribution of arsenic across the subject property suggest that the detected concentrations are a result of naturally-occurring arsenic, and not contamination resulting from a release to site soils.
Benzene was detected in one groundwater sample (TMW-2 at 5.95 micrograms per liter (�g/L)) slightly above the EPA MCL. The contaminant is likely migrating from a release at the gas station on the northeast adjoining property; however, based on the concentration, depth, and distance, it does not represent a vapor intrusion risk to the building on the subject property. No other concentrations of target analytes were identified in the groundwater samples analyzed from the subject property above the laboratory RLs applicable screening criteria.
The RECs associated with the subject property identified in PM's April 2022 Phase I ESA have been adequately assessed. Based on the expected continued use of the property for commercial purposes and no complete exposure pathway for on-site groundwater, no further investigation is warranted.
