The U.S. Environmental Protection Agency on September 9 announced a new scientific study using cutting-edge methods to improve the agency’s understanding of what pollutants may be present in drinking water.
This new research by EPA scientists goes beyond traditional testing methods to screen for a broad array of pollutants, including pharmaceuticals, PFAS, and more than 1000 potential contaminants.
This scientific assessment will use Non-Targeted Analysis, which can identify unknown pollutants present in a drinking water sample. While conventional analytical methods measure a handful of specific chemicals at a time, Non-Targeted Analysis allows researchers to scan for thousands of potential pollutants. The resulting insights will help the EPA prioritize future actions to ensure that drinking water is safe.
The agency’s new study complements existing Safe Drinking Water Act programs being implemented by the EPA by filling gaps in the other steps being taken. In June, the agency proposed its Sixth Unregulated Contaminant Monitoring Rule (UCMR 6), which would require monitoring for contaminants not currently regulated but may be present in drinking water. UCMR 6 would require monitoring using existing approved methods to detect 30 unregulated contaminants, including PFAS.
