Guidance to Help Implement Drinking Water Regulations

EPA is releasing draft guidance to support revisions to the Lead and Copper Rule, which were issued in October 2007. The revisions to the rule will enhance implementation in the areas of monitoring, treatment, customer awareness, public education, and lead service line replacement. EPA requests input on six draft documents that will assist states and public water systems with understanding the revisions, including State Implementation Guidance, Guides, and Fact Sheets to understand the new Public Education and other Public Information requirements, and a Quick Reference Guide. The documents, which are available for comment through Jan. 31, 2008, are available at

EPA is also releasing a poster, "Removing Multiple Contaminants from Drinking Water: Issues to Consider," to help regulators and water organizations better assist small water systems with drinking water treatment. Public water systems that need to add treatment for one contaminant, such as arsenic, may find that they need to consider other water-quality issues. Choosing a treatment technology that can remove several co-occurring contaminants may be more efficient and cost effective. This poster describes treatment technologies that can remove multiple contaminants, identifies the contaminants that can be removed, and summarizes related operational and waste disposal issues.
