Document Description
The Project consists of the installation of small treatment plants at each of the four existing City of Orange groundwater production well sites for the treatment of PFAS contaminants. The treatment plants would use an ion exchange (IX) treatment protocol through the use of cartridge filtration and IX vessels. New cartridge filters and IX treatment vessels would be installed at all four well sites. A new booster pump would be added at well site 24 to accommodate the changed hydrologics introduced by the treatment facility. Each of the four sites have been previously disturbed by the development of the existing groundwater production wells, the Project would not require any new ground disturbances. The facilities would treat water pumped from the existing production wells and would convey it to existing water distribution pipelines for potable water consumption. The Project would not require any native vegetation removal and each facility is located within urbanized portions of the City of Orange.
