In addition to a chlorinated solvent plume from the nearby Naval Air Development Center (NADC), groundwater impacts from Per and Polyfluoroalkyl Substances (PFAS) were confirmed to be present at sample locations on our client’s property at concentrations exceeding the U.S. Environmental Protection Agencies (EPA) health advisory level of 70 parts per trillion (ppt). The source of the PFAS were fire-fighting foams that had been used during exercises at the air base for many years and had seeped into the groundwater.
To determine the extent of existing groundwater impacts beneath the Site, Brickhouse Environmental collected groundwater samples from five clustered wells that had been installed by the NADC. The wells were designed and installed to monitor multiple depths within the multi-aquifer system. Monitoring well sampling methods were conducted in alignment with the U.S. Environmental Protection Agency, using Low Flow Purging and Sampling equipment and procedures and in alignment with current industry sampling procedures for the collection of PFAS samples.
The samples were successfully analyzed by ELLE for PFOA, PFAS, PFHxS, and related compounds using cutting-edge methodologies and certified PFAS-free equipment. All purging and sampling procedures, and sample handling and analytical procedures at the lab were conducted using strict QA/QC protocols to eliminate potential cross-contamination and/or false positives.
