A diverse group of drinking water providers and environmental and health organizations applauded yesterday¡¯s announcement of a revised rule to safeguard U.S. drinking water. A pre-publication copy of the final Revised Total Coliform Rule (RTCR) was released Dec. 20 by the U.S. EPA and will be published in the Federal Register in the next few weeks. Significant improvements were made during the revision process, including new requirements that ensure assessment and corrective action when monitoring results indicate a potential risk of contamination exists.
