Stoneridge Well PFAS Treatment System Project
In a continuing effort to supply the Tri-Valley with safe, reliable water that surpasses state and federal drinking water standards, Zone 7 is implementing a water treatment system to address Per- and Polyfluoroalkyl substances (PFAS) found in the local groundwater at the Stoneridge Well.
ABOUT THE PROJECT
- The purpose of the project is to add necessary water treatment facilities to the existing Stoneridge Well to remove PFAS from the well’s groundwater supply.
- Construction is taking place at Zone 7’s Stoneridge Well, located at 3750 Stoneridge Drive in Pleasanton.
