Jacobs announced on Wednesday that the company has been selected to design, build, operate and optimize a Wetland/Electro-Coagulation Treatment Facility by the Kaiser Mead Custodial Work Trust to clean up groundwater cyanide, fluoride and nitrate pollution at the Kaiser Aluminum (Mead Works) Superfund site in Mead, Washington.

“Our Spokane-based team combines their knowledge of local hydrogeology with national technical expertise in extraction, wetlands and water chemistry,” said Jacobs Buildings, Infrastructure and Advanced Facilities Global Environmental Solutions Senior Vice President and General Manager Jan Walstrom. “We will also be utilizing local Jacobs operations and maintenance resources located at the Spokane Regional Water Reclamation Facility, less than 10 miles away, to provide low cost, safe and responsive operation of the treatment facility.”

Jacobs’ technical solution integrates an extraction well system for maximizing contaminant capture; subsurface biological treatment wetlands to deliver consistent four-season removal of cyanide and nitrates; an electro-coagulation system for removal of fluoride and residual cyanide/nitrates; sludge disposal management for hazardous and nonhazardous waste and an effluent discharge infiltration basin to reduce the potential mobilization of secondary groundwater plume contamination.
