The Environmental Protection Agency (EPA) has approved two new methods to test contaminants in drinking water, as outlined in a rule published in the Federal Register. This action permits public water systems and related agencies to use these alternative methods, offering more flexibility and potentially lowering monitoring costs without compromising public health. The approved methods, effective January 16, 2025, are EPA Method 537.1 for detecting selected PFAS chemicals and the e-sens Automated Micro Chlorine Detection Method for measuring free and total chlorine. These alternative methods are considered as effective as existing methods and are added as options for compliance under the Safe Drinking Water Act.
Simple Explanation
The EPA has approved two new ways to check if drinking water is safe by testing for certain chemicals and chlorine. This makes it easier and cheaper for people to keep water clean without making it less safe.
