ERAS took over a contaminated gasoline station from a former environmental consultant. Work performed by ERAS included installation of groundwater monitoring, vapor extraction and groundwater extraction wells. Soil borings were drilled in off-site areas to assess the extent of groundwater contamination under the residential neighborhood. Work also included hazardous and non-hazardous waste disposal coordination, groundwater monitoring, and preparation of a feasibility study.
A risk assessment was also performed that indicated the groundwater plume was stable and decreasing in concentration. No indoor air issues were indicated by analysis of soil and groundwater samples. ERAS eventually conducted case closure activities and the case was closed by the San Mateo County Department of Environmental Health.
