This publication, recently posted online by the Environmental Protection Agency (EPA), describes the variety of technology findings for contaminants regulated before 1996. The report, available in .pdf format only, is organized into five chapters. Topics included in the chapters are "the 1996 Safe Drinking Water Act (SDWA) and the overall approach EPA is following to meet these requirements, . . . the two-stage screening process that was used to identify those contaminants that would have technology costs compared against the national-level affordability criteria, . . . affordable technology determinations and how treatment costs are compared against the national-level affordability criteria, . . . [and] a summary of the variance technology findings." In addition, two appendices, figures, and tables supplement the findings.
