Specific Plan Open Space (North Valencia Specific Plan), public rights-of-way
Document Description
The project involves construction of a per- and polyfluoroalkyl (PFAS) groundwater treatment and disinfection facility and associated pipelines. The proposed facility would restore the use of Wells S6, S7 and S8 and would reduce SCV Water’s dependency on imported water. In addition, a new groundwater well (S9) and a chloramine disinfection building would be constructed. The new S9 well would produce an additional 1,000 gallons per minute of potable water that would also be filtered through the proposed PFAS treatment system before distribution to SCV Water customers. The new Well S9 would serve as a replacement for the existing Mitchell 5A Well that is being abandoned by a private developer as part of the Vista Canyon Plaza Development; therefore, the new Well S9 would not result in a net increase in SCV Water’s overall annual basin-wide groundwater extraction levels.
