On October 31 and November 1, 2022, PM advanced eight soil borings (SB-3 through SB-10), installed eight temporary monitoring wells (TMW-3 through TMW-10) to a maximum depth of 17.5 feet below ground surface (bgs), and collected a total of 19 soil and four groundwater samples for laboratory analysis of volatile organic compounds (VOCs), polynuclear aromatic hydrocarbons (PAHs), and metals (cadmium, chromium, and lead).
No concentrations of target analytes were identified in any of the groundwater samples analyzed from the subject property above the laboratory Method Detection Limits (MDLs) and/or applicable criteria.
No concentrations of VOCs or PAHs were detected in any of the soil samples analyzed above the laboratory Reporting Limits (RLs) and/or the Regional Screening Levels (RSLs) for Commercial Soils. Lead was identified in one soil sample (SB-6 at 4.0-5.0 feet bgs) at a concentration exceeding the applicable RSL for Commercial Soil. No other metals were detected above the applicable RSLs.
The lead-impacted soils appear to be associated with the former gasoline underground storage tank (UST) basin. Based on soil results collected at 5.0-7.5 feet bgs interval, the vertical extent of the lead impact has been delineated to within screening levels; however, the horizontal extent has not been defined. PM recommends additional assessment in the vicinity of the former gasoline USTs to define the horizontal extent of the lead contamination in soil.
Concentrations of VOCs and PAHs are present in the soils at some sampling locations. Although these concentrations are below the applicable criteria, if the subject property is redeveloped, PM recommends that any soils removed from the site that are unsuitable for construction be properly characterized prior to off-site disposal.
Proposed soil borings SB-1 and SB-2 could not be installed due to interior obstructions that prevented access by a drill rig, and subsurface obstructions at 0.67 feet bgs that prevented the collection of subsurface samples with a hand auger. Additional assessment is required in the vicinity of the former in-ground hoist to determine whether the subsurface has been impacted by a release from the former hydraulic system.
