Frequent Questions

Does EPA publish clarifying memoranda for different Safe Drinking Water Act (SDWA) topics?

EPA periodically issues memoranda that clarify drinking water policies and regulations.  These policy memos have been collected into a water supply guidance manual that has been made available to states and public water systems to assist them in implementation of the SDWA.  The manual was most recently updated in January of 2000 to add new memos and remove memos that no longer apply.  The manual includes 135 policy memos and fifty-two guidances from the Safe Drinking Water Hotline.  The Public Water System Supervision Program Water Supply Guidance Manual (EPA816-R-00-003; January 2003) is available at http://water.epa.gov/lawsregs/guidance/sdwa/wsg.cfm.
