EPA proposes updating drinking water rule to better protect public health

by Jbs062610 i3 — July 2, 2010—The U.S. Environmental Protection Agency (EPA) is proposing to revise a national primary drinking water regulation to achieve greater public health protection against illness-producing waterborne pathogens in the distribution systems of public water systems.

EPA is proposing to revise the 1989 Total Coliform Rule to incorporate improvements recommended by a federal advisory committee that included representatives from a broad range of stakeholder groups, including public health and public interest groups, environmental groups, state drinking water agencies and drinking water utilities.

The revised rule will better protect people from potential exposure to dangerous microbes because it requires water systems to take action when monitoring results indicate that contamination or a pathway to contamination may be present, says EPA.

The proposal also provides incentives for better system operation by improving the criteria for public water systems to qualify for and stay on reduced monitoring, which provides an opportunity to reduce system burden. In addition, the proposed rule updates conditions that will trigger public notices to better represent the relative health threat identified.

EPA is seeking public comment on this proposed rule for 60 days following its upcoming publication in the Federal Register.
