The S Wells PFAS Groundwater Treatment and Disinfection Facility Project, identified by project number 1910240-002C, is being implemented by the Santa Clarita Valley Water Agency in Santa Clarita, Los Angeles County. Funded by the State Water Board, the project aims to restore the use of Wells S6, S7, and S8 to reduce dependency on imported water. The scope of work includes the construction of a per- and polyfluoroalkyl substances groundwater treatment and disinfection facility, a chloramine disinfection building, a new groundwater well designated as S9, and an underground 12-inch drainage pipeline connection with approximately 2,100 linear feet of associated pipelines. Additionally, the project involves critical upgrades to existing Wells S6, S7, and S8, including the replacement of submersible pumps and electrical panel upgrades. The project is classified under NAICS code 237110 and has undergone environmental review under the California Environmental Quality Act, resulting in a Mitigated Negative Declaration confirming that the project will not have significant environmental effects. Key administrative oversight is provided by Principal Engineer Orlando Moreno of the Santa Clarita Valley Water Agency and Environmental Scientist Michaela Grubb of the State Water Board. While financing was approved on July 23, 2026, and the project is listed as a forecast with a posted date of July 29, 2026, specific contract values and performance periods are not detailed in the provided documentation.
