City of Ramsey Project B1700969 March XX, 2017 Page 9 DRAFT The following provides a summary of the soil analytical results from the Phase II ESA. ■ No VOCs were detected at concentrations greater than or equal to the laboratory reporting limits. ■ Varying concentrations of PAHs were detected in 4 of the 9 soil samples analyzed. The concentrations of the detected PAHs were below Residential SRVs and SLVs. ■ No DRO were detected at concentrations greater than or equal to the laboratory reporting limits. ■ GRO was detected in 4 of the 9 soil samples analyzed. The concentrations of GRO did not exceed the MPCA unregulated fill criterion of 100 mg/kg. ■ Varying concentrations of the eight RCRA metals were detected in each of the soil samples analyzed. However, none of the metal concentrations exceeded the respective Residential SRVs and SLVs. F.4. Groundwater Analytical Results A summary of the groundwater analytical results is provided in Table 2. The complete laboratory reports with chain -of -custody forms are included in Appendix D. For comparison purposes, Table 2 includes Drinking Water Criteria from the Minnesota Department of Health (MDH) Human Health -Based Water guidance. Drinking Water Criteria include MDH Health Risk Limits (HRLs), MDH Health Based Values (HBVs), MDH Risk Assessment Advice (RAA), and Maximum Contaminant Levels (MCLs) established by the Environmental Protection Agency (EPA). Concentrations of contaminants in water and Drinking Water Criteria are expressed in units of micrograms per liter (µg/L). The following provides a summary of the groundwater analytical results. ■ No VOCs were detected at concentrations greater than or equal to the laboratory reporting limits. ■ DRO was detected at a concentration of 140 µg/L in groundwater sample GP-15, which is below the provisional MDH HBV of 200 µg/L for total petroleum hydrocarbons.
