II. Background

The Safe Drinking Water Act (SDWA) requires the EPA to promulgate rules establishing criteria for a monitoring program for unregulated contaminants in drinking water. Monitoring varies based on system size, source water, and contaminants likely to be found. SDWA also specifies that for systems serving 10,000 persons or fewer, only a representative sample of systems must monitor. Per SDWA, EPA is required to issue, every five years, a list of not more than 30 unregulated contaminants to be monitored by public water systems. The third and most recent rule (UCMR 3) was published on May 2, 2012. The fourth (UCMR 4) is scheduled to be published by December 2016.
