EPA Submits for Public Comment the Next Round of Safe Drinking Water Act Contaminant Monitoring
Under the authority of the Safe Drinking Water Act, EPA currently regulates more than 90 contaminants in drinking water. To keep drinking water standards up-to-date with emerging science, the Safe Drinking Water Act 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 public comment period, EPA will consider this important input before the list is scheduled to be finalized 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.
