Occurrence Assessment for Disinfectants and Disinfection By-Products (Phase 6a)in Public Drinking Water

摘要

The EPA Office of Ground Water and Drinking Water is developing national primarydrinking water regulations for disinfectant and disinfection by-product contaminants. Thirteen contaminants are being considered to be regulated under Phase 6. These contaminants, referred to as Phase 6a, are the subject of the report. The information is important for setting the Maximum Contaminant Level Goal for a contaminant. The exposure information also is used to estimate the 'baseline' health impact assessment of current levels and for evaluation of the health benefits of the regulatory alternatives.
