Nearly 4,000 public water treatment systems will be monitoring their drinking water for as many as 25 currently unregulated chemicals. The agency is interested in learning about the concentrations and frequency in which these chemicals show up in the nation's water systems.
This is the second such review under the unregulated contaminant monitoring rule. This rule requires the EPA to come up with up to 30 contaminants that are not currently monitored for testing every five years. Currently, the agency lists 90 contaminants requiring monitoring and control. More information about the unregulated contaminant monitoring rule is available at www.epa.gov/safewater/ucmr/ucmr2.
