South Basin Groundwater Protection Project

South Basin Groundwater Protection Project

The proposed Project is a groundwater extraction and treatment system that would extract contaminated groundwater from the Shallow Aquifer System, treat the water locally, then discharge the treated water to the sanitary sewer system. The treated groundwater would then mix with other wastewater flows in the sewer, which ultimately flow to OC San’s Reclamation Plant No. 1 in Fountain Valley, California. The Project would include the installation and operation of below ground groundwater extraction facilities (wells, trenches, and/or drains equipped with pumps) and conveyance piping, local groundwater treatment facilities for sediment and VOCs removal using filtration and granular activated carbon (GAC), and discharge piping to the sanitary sewer system. The Project will use the existing treatment facilities at the Public Owned Treatment Works (POTW) and GWRS and will not require the construction of new treatment, transportation, or recharge facilities after the point that the treated water joins the sanitary sewer system.
