EPA is proposing a rule which specifies the appropriate use of disinfection in ground water and addresses other components of ground water systems to assure public health protection.

The Ground Water Rule (GWR) establishes multiple barriers to protect against bacteria and viruses in drinking water from ground water sources and will establish a targeted strategy to identify ground water systems at high risk for fecal contamination.

The GWR is scheduled to be issued as a final regulation in November of 2000.
