No comprehensive federal groundwater protection law exists. Instead, groundwater is protected through a variety of federal laws that address various aspects of groundwater protection and remediation. A table summarizes federal groundwater-related statutes in place as of January 1991. Groundwater-related laws and associated regulatory programs are discussed in this overview. Superfund is the largest federal program involving groundwater, although there is substantial debate over the benefits actually realized from the resources being applied. As the Clean Water Act evolves from an almost exclusive focus on point-source discharges to increasing regulatory control over nonpoint sources, its relevance to groundwater increases. Several Safe Drinking Water Act provisions relate to groundwater protection directly and indirectly. Other relevant statutes include the Toxic Substances Control Act; Federal Insecticide, Fungicide, and Rodenticide Act; Surface Mining Control and Reclamation Act; Comprehensive Environment Response, Compensation, and Liability Act; Food Security Act (as amended by the 1990 Farm Bill); Water Resources Development Act; Uranium Mill Tailings Radiation Control Act; and the Water Resources Research Act.
