Authorize appropriations for grants to states to address “emerging contaminants” in drinking water
Direct the U.S. Geological Survey (USGS) to set concentration standards for perfluoroalkyl and polyfluoroalkyl substances (PFAS) in water
Direct the Environmental Protection Agency (EPA) to study, monitor, and regulate PFAS and emerging contaminants in drinking water and to issue rules and guidance
Establish a multiagency research initiative regarding emerging contaminants
Impose intergovernmental mandates by requiring public water systems to meet new drinking water standards for PFAS and private-sector mandates by requiring facilities that use or manufacture PFAS to comply with new reporting requirements
Estimated budgetary effects would primarily stem from
Authorizations of appropriations for EPA and USGS
Additional costs for EPA to study and report on PFAS standards, participate in a working group and research initiative, and issue new regulations
Reductions in federal revenues arising from increased issuance of tax-exempt bonds
Areas of significant uncertainty include
Projecting the costs of testing and analysis of toxic compounds in water
Estimating the number of compounds that EPA would regulate
