Drinking Water Bureau

Public Water System Supervision Group

The PWSS group supports the implementation of new federal and state regulations, provides public water system (PWS) monitoring for regulation compliance, and issues violations to PWS that are out of compliance.

Drinking Water Laws & Regulations – The New Mexico Environment Department Drinking Water Bureau (DWB) has primacy for the federal Safe Drinking Water Act (SDWA), which means it has the authority to implement and enforce the primary SDWA regulations. When the U.S. Environmental Protection Agency (EPA) announces a new rule/regulation, PWSS works with the EPA for its implementation and enforcement. Similarly, the DWB has authority to implement and enforce New Mexico regulations. 

Enforcement – When public water system monitoring or site inspection findings indicate that a public water system is out of compliance, the Enforcement Program issues a violation notice.  If compliance is not attained by the public water system, an escalating series of violation actions may be implemented.  The EPA may become involved with serious violations to support the efforts of the DWB. Some compliance issues may require court action.

Safe Drinking Water Information System (SDWIS) – SDWIS contains information about public water systems, include water quality data, non-compliance and violations. The New Mexico Environment Department Drinking Water Bureau PWSS group manages New Mexico’s public water system information in SDWiS.
