What US Safe Drinking Water Act - 42 U.S.C. § 300f - National Primary Drinking Water Regulations requires
The Safe Drinking Water Act (42 U.S.C. §§ 300f-300j-26) authorizes EPA to set National Primary Drinking Water Regulations (NPDWRs) for public water systems serving 25 or more persons. EPA has set Maximum Contaminant Levels (MCLs) and treatment techniques for 90+ contaminants at 40 CFR Parts 141-143. AI-based water quality prediction, lead service line detection, PFAS monitoring, and digital twin water distribution systems must operate within SDWA regulatory framework. The 2024 PFAS rule (40 CFR 141.803) established MCLs of 4 ppt for PFOA and PFOS - first new MCLs in 20+ years - directly affecting AI contamination prediction models.
