The Era of Cleaner Tap Water: New Regulations on Toxic Chemicals
Stricter Limits on Forever Chemicals in Drinking Water
The U.S. Environmental Protection Agency has introduced groundbreaking regulations on toxic “forever chemicals” in drinking water. These regulations aim to virtually eliminate the presence of per- and polyfluoroalkyl substances (PFAS) in American tap water. PFAS, known for their persistence and health risks, are commonly found in various products.
Comprehensive Guidelines for Water Systems
The EPA’s new rule mandates strict limits on five individual PFAS types, with a range of 4 to 10 parts per trillion. Public water systems have three years to monitor these chemicals, informing the public of the levels found. If levels exceed standards, systems must reduce PFAS within five years, ensuring safe drinking water for all.
Enhancing Existing PFAS Regulations
This rule is a significant step in the EPA’s PFAS roadmap, strengthening regulations on these harmful substances. Previous measures required reporting of PFAS use, limiting new manufacturing processes, and more. Further rules are expected to designate PFAS as hazardous substances, expanding cleanup responsibilities.
Potential Legal Challenges and Enforcement
Legal challenges to the rule are anticipated from manufacturers, business groups, and water systems due to compliance costs and evidence considerations. Enforcement will be primarily handled by states under the Safe Drinking Water Act, with federal intervention if necessary. Fines for non-compliance may follow warnings and legal actions.
Implications for Ongoing Lawsuits
The new rule could bolster existing lawsuits against manufacturers for PFAS contamination. Major settlements have already been reached, with potential for more as litigation progresses. Clear standards in the rule make it easier for affected water systems to seek compensation for damages caused by PFAS pollution.
