What does it do?

SB1662 lets the Texas Commission on Environmental Quality give certain groundwater-supplied public drinking-water systems up to 24 hours’ notice before complaint-related water-quality testing. Notice is optional, not a guaranteed warning or a mandatory waiting period. Signed May 30, 2025; effective September 1, 2025. Final law; Official history.

What changed along the way?

The new Health and Safety Code Section 341.0317 applies when the commission intends to test water quality to investigate a complaint about a public drinking-water system that obtains its supply from underground sources. “Not more than 24 hours in advance” is a maximum lead time, not a requirement to give at least 24 hours. The act does not require notice before every inspection, cover all surface-water systems, give operators a right to stop testing, or change water-quality limits. Final law.

The introduced, Senate committee, Senate-passed, House committee and enrolled operative text are the same. Neither committee substituted a different policy and no floor amendments are indexed. Introduced; Senate committee; Senate-passed; House committee; Final law; Version index; Amendment index.

Who could benefit—and who could bear the costs?

Eligible operators may use short advance notice to arrange staff or access for a test. Residents still depend on the testing process to investigate their complaints; the act does not itself establish that notice will improve or weaken testing accuracy or change contamination levels. Any benefit depends on how the commission uses this discretion. Final law.

The April 3 fiscal note anticipates no significant state or local-government fiscal impact and assumes costs can be absorbed using existing resources. It provides no dollar estimate or quantified household savings. The act makes no appropriation and imposes no new testing fee. Fiscal note; Final law.
