Which agency defines public water systems in Texas?

The Texas Commission on Environmental Quality (TCEQ) is the agency responsible for defining public water systems in Texas. This agency oversees water quality and environmental regulations within the state, ensuring the protection of public health and the environment. TCEQ establishes rules and standards for public water systems, conducts inspections, and monitors compliance with both state and federal regulations.

While the Environmental Protection Agency (EPA) sets national standards for water quality and oversees public water systems at the federal level, the TCEQ is tasked with the local implementation and enforcement of these standards in Texas. The Department of Water Resources does not exist as a standalone agency in Texas and is not responsible for the management of water systems. The Texas Department of Health Services focuses more on public health policies and does not specifically define public water systems; rather, it may work in conjunction with TCEQ on health-related issues pertaining to water quality. Thus, the TCEQ's role in defining public water systems is paramount for regulatory compliance and public safety in the state.
