Abstract |
The Safe Drinking Water Act (SDWA) of 1974 requires that The Environmental Protection Agency (EPA) establish maximum contaminant level goals (MCLG) for each contaminant in drinking water which may have an adverse effect on the health of persons. Each goal is required to be set at a level at which no known or anticipated adverse effects on health occur, allowing an adequate margin of safety. The SDWA also requires that National Primary Drinking Water Regulations (NPDWRs) establishing maximum contaminant levels (MCLs) or treatment techniques, and secondary drinking water regulations be established. The purpose of this paper is to describe the activities of the Drinking Water Research Division (DWRD) of EPA in evaluating the various technologies that may be available for achieving these MCLs. |
