The 11th edition of the Safe Drinking Water Act wall chart is now available from HDR. The company has printed and distributed nearly one million charts to water utilities, schools and individuals around the world since 1994.
The poster-sized chart provides an easy-to-use reference for all drinking water regulations including a detailed listing of contaminants and maximum contaminant levels, health effects and monitoring requirements. Emphasis this year is on simultaneous compliance with multiple regulations, in particular two new rules established by the U.S. EPA in January. The rules are the Stage 2 Disinfectants and Disinfection Byproducts Rule and the Long Term 2 Enhanced Surface Water Treatment Rule. Both regulations add monitoring requirements and have expedited implementation schedules.
