Unregulated Contaminant Monitoring Regulation Proposal

U.S. Environmental Protection Agency (EPA) is proposing 30 currently unregulated contaminants for monitoring in water systems. Under the authority Safe Drinking Water Act (SDWA), EPA currently regulates more than 90 contaminants in drinking water. The SDWA requires that EPA identify up to 30 unregulated contaminants for monitoring every five years. This current proposal is the third Unregulated Contaminant Monitoring Regulation and includes requirements to monitor for two viruses and 28 chemical contaminants that could be present in drinking water and do not currently have health-based standards.

EPA is requesting public comment on the proposed list of 30 contaminants until May 2, 2011. Following the comment period, EPA will consider input and finalize the list in 2012, with sampling to be conducted from 2013 to 2015. Sampling will take place at all systems serving more than 10,000 people and at a representative sampling of systems serving less than 10,000 people.
