Characterization of Chlorinated VOCs Adjacent to the Portland Harbor Superfund Site
Client: Confidential / Portland, Oregon
MFA's investigation of this site started when chlorinated volatile organic compounds (solvents) were found during an investigation of 1950s-era manufactured gas plant waste. MFA designed and implemented a forensic groundwater assessment to identify the source of the solvents and other legacy impacts. Subsequently, MFA conducted a remedial investigation of impacts to air, soil, sediment, surface water, transition zone water, and groundwater from three different groundwater plumes. Throughout the investigation work, MFA has applied state-of-the-art drilling technologies that avoid vibrations that would affect extremely sensitive equipment.
