The project scope includes design services, construction of the pilot treatment facility, and operational testing and evaluation phases. Work is to be performed at the Potomac Water Filtration Plant located in the Washington DC metropolitan area. The contractor must demonstrate qualifications in water treatment plant design and construction, pilot project management, and PFAS remediation technologies.
