Case Studies
Client: Port of Redwood City
Location: Redwood City , California
Project Description
Provided mobile on-site wastewater treatment, oil and sludge treatment services to the Port of Redwood City as a key element to a Consent Order issued by the California Environmental Protection Agency for the former Gibson Environmental TSDF. The TSDF was abandoned and the existing waste was left unprocessed contained in multiple aboveground storage tanks. Approximately 6.8-million gallons of RCRA contaminated waste was treated on-site with approvals from the DTSC, South Bayside System Authority (POTW) and the Bay Area Air Quality Management District. The waste was contained in large aboveground storage tanks and was contaminated with Benzene, MTBE, gasoline, diesel, heavy metals, sulfides, oils and grease. The untreated waste material also possessed solids up to 50% by volume. Innovative, unique and patented treatment techniques developed by GEM MTS were used to achieve the treatment goals. The water phase was segregated, treated, and disposed of into the sewer. Over 5,200-tons of sludge waste was treated, rendered non-hazardous and disposed of off-site at a non-hazardous waste landfill. The treatment processes included oil/water separation, metal precipitation, chemical oxidation, air stripping, thermal oxidation, benzene sludge reduction and centrifugation.
