Boomer Lake Station Phase II ESA
Location: Stillwater, OK
Phase II ESA – As part of an EPA Region 6 Targeted Brownfield Assessment, a Phase II Environmental Site Assessment (ESA) was performed at a former power generating facility to investigate the recognized environmental conditions (RECs) identified in the Phase I ESA: Halogenated solvent spill at the west adjoining automotive dealership and repair facility.
Soil Sampling – Eight soil borings were advanced to three feet below ground surface on the west side of the property. Two soil samples were collected from each boring and analyzed for volatile organic compounds.
Indoor Air Sampling – One ambient air sample and two indoor air samples were collected during the investigation to evaluate the possibility of vapor intrusion into the former power station building. Air samples were analyzed for volatile organic compounds.
Report – Concentrations of volatile organic compounds in soil and air were compared to the EPA Regional Screening Levels. Concentrations in soil exceeded the soil protective of groundwater screening level but were below the residential soil screening level. Concentrations detected in the air samples collected were below the EPA Regional Screening Levels.
