General Plan Designation: Open Space (OS), Zoning: Open Space (OS)
Document Description
The proposed project would involve construction and operation of a new groundwater treatment facility for treatment of perchlorate and other groundwater contaminants at the existing Well 205 site. Under the project, Well 205 would be reactivated, and all existing facilities would remain in place. The development footprint of the proposed groundwater treatment facility would be approximately 33,000 square feet, or approximately 0.8 acre. Groundwater pumped from Well 205 would proceed through pre-filters, granular activated carbon (GAC) vessels, ion exchange (IX) vessels, and chemical injection before connecting to an existing water distribution pipeline on the project site The project would not increase the production capacity of Well 205, and consistent with previous operating conditions, Well 205 would be equipped to produce up to 2,700 gallons of groundwater per minute from the Saugus Formation of the Santa Clara River Valley Groundwater Basin. The project would treat up to 4,360 acre-feet per year of groundwater. The new treatment facility would consist of a chemical building, water tanks, pumps, and treatment equipment alongside existing facilities at the site. Construction of the new groundwater treatment facility would occur between mid-2023 and mid-2024. Maintenance of the proposed project would include regular backwashing, replacement of filtration media, and routine performance monitoring and sampling. Maintenance staff would visit the project site daily, 365 days per year. Regular and routine maintenance activities would not include any ground-disturbing activities.
