Drinking Water Survey Reports

TCEQ Report Required for Sites with Groundwater Contamination

The Texas Water Code (TWC) §26.408 requires the TCEQ, within 30 days of receiving notice or otherwise becoming aware of groundwater contamination, to notify:

• Owners of private drinking water wells that may be affected; and
• Residents located within one mile of the site of contamination.

To carry out this statutory requirement, TCEQ must obtain accurate and timely information on the location of private water wells and other local drinking water supplies. RG-428: Preparation of a Drinking Water Survey Report provides instructions for identifying and reporting this information in areas where groundwater contamination has been reported to the TCEQ on or after September 1, 2003.

To ensure a timely response, the Drinking Water Survey Report should be submitted concurrently with the initial groundwater contamination report. If the Remediation Division must request the report, the responsible party is required to respond within seven days indicating whether a water well search will be conducted, and to submit the completed Drinking Water Survey Report within thirty days of receiving the request from TCEQ.
