Drinking Water Survey Reports

Provides information on complying with Texas Water Code 26.408.

TCEQ Report Required for Sites with Groundwater Contamination

The Texas Water Code (TWC) §26.408 requires the TCEQ, within 30 days of the date the TCEQ receives notice or otherwise becomes aware of groundwater contamination, to notify owners and users of private drinking water wells that may be affected by the groundwater contamination (ingestion standards exceeded).

The TCEQ needs critical local drinking water supply information and private water well locations within a short time frame to implement TWC §26.408. The Drinking Water Survey Report instructs users on how to collect and report information on water wells and sources of drinking water in the area near groundwater contamination reported to the TCEQ on or after September 1, 2003.

To ensure a timely response, we ask that the person submit the Drinking Water Survey Report at the same time as reporting groundwater contamination. If the Remediation Division has to ask for one, the person will need to reply within 7 days as to whether they will conduct a search for water wells, and then must submit the completed Drinking Water Survey Report within 30 days of receiving the request from TCEQ.
