EPA proposes sixth round of drinking water contaminant monitoring

Table of Contents
The Environmental Protection Agency is proposing a rule that would require many public water systems to test for 30 chemicals not currently regulated at the federal level. These tests are part of the Unregulated Contaminant Monitoring Rule, or UCMR, which gathers data on what is in the nation’s drinking water without mandating specific cleanup levels yet.
Why it matters: This rule does not set legal limits or require water systems to remove these chemicals. Instead, it fills a data gap so the EPA can understand how widespread these substances are in drinking water supplies. The information gathered will inform future regulatory decisions under the Safe Drinking Water Act.
Who it affects
- Community water systems serving 3,300 or more people
This is a proposed rule from the EPA published in the Federal Register; readers should check the original document for full details before relying on it.
