Well Standards
ACWD Well StandardsWell Standards
ACWD’s Well Standards have been developed to protect the health, safety, and general welfare of the people of the Cities of Fremont, Newark, and Union City by ensuring the groundwater within the area of the Cities will not be degraded, polluted, or contaminated by improper construction, use, operation, maintenance, repair, reconstruction, improvement, inactivation, decommissioning, or destruction of wells, exploratory holes, other excavations, and appurtenances. 

The above Standards are derived from water well industry procedures and processes deemed most effective at meeting local groundwater protection needs and are based on the standards developed by the State of California Department of Water Resources (DWR).
