S.B. No. 1662 amends the Health and Safety Code by adding a new section, 341.0317, which establishes a requirement for the Texas commission to provide advance notice of water quality testing to certain public drinking water supply systems. Specifically, the bill allows the commission to notify these systems, which source their water from underground, no more than 24 hours before conducting tests related to complaints about water quality. This provision aims to enhance communication and transparency between the commission and public drinking water systems regarding water quality issues.

The bill is set to take effect on September 1, 2025, following its passage in both the Senate and the House with overwhelming support. The Senate approved the bill with a vote of 31-0, while the House passed it with a vote of 144-1, indicating strong bipartisan agreement on the importance of ensuring safe drinking water and proper notification procedures for water quality testing.
