Drinking Water Well Testing

The Alameda County Public Works Agency (ACPWA), Water Resources Section does not conduct water well testing. This is generally done by private state certified laboratories. For more information, please see Other Useful Links below.

ACPWA recommends that bacterial testing be conducted at least once a year for all drinking well water. For more information, see the Alameda County Department of Environmental Health document on Drinking Water Well Testing.

Drinking water well test data may be obtained through ACWPA, Water Resources Section or through the Alameda County Health Care Services Department at:
