Safe Drinking Water Act (SDWA): Selected Regulatory and Legislative Issues [July 27, 2010]   [open pdf - 309KB]

"Much progress has been made in assuring the quality of public water supplies since the Safe Drinking Water Act (SDWA) was first enacted in 1974. Public water systems must meet extensive regulations, and water utility management has become a much more complex and professional endeavor. The Environmental Protection Agency (EPA) has regulated some 91 drinking water contaminants, and more regulations are pending. In 2007, the number of community water systems reporting no violations of drinking water standards was 89.5%. Despite nationwide progress in providing safe drinking water, an array of issues and challenges remain. Recent issues have involved infrastructure funding needs, regulatory compliance issues, and concerns caused by detections of unregulated contaminants in drinking water, such as perchlorate and pharmaceuticals and personal care products (PPCPs). Another issue involves the adequacy of existing regulations (such as trichloroethylene (TCE)) and EPA's pace in reviewing and potentially revising older standards. Congress last reauthorized SDWA in 1996. Although funding authority for most SDWA programs expired in FY2003, Congress continues to appropriate funds annually for these programs. No broad reauthorization bills have been proposed, as EPA, states, and water systems continue efforts to implement current statutory programs and regulatory requirements. A long-standing and overarching SDWA issue concerns the cumulative cost and complexity of drinking water standards and the ability of water systems, especially small systems, to comply with standards."
