The U.S. Environmental Protection Agency (EPA) is revising the Consumer Confidence Report (CCR) Rule in accordance with America's Water Infrastructure Act (AWIA) of 2018 (United States, 2018) and is requiring States, territories, and Tribes with primary enforcement responsibility to report compliance monitoring data (CMD) to the EPA. The revisions will improve the readability, clarity, and understandability of CCRs as well as the accuracy of the information presented, improve risk communication in CCRs, incorporate electronic delivery options, provide supplemental information regarding lead levels and control efforts, and require systems who serve 10,000 or more persons to provide CCRs to customers biannually (twice per year). The final rule requirements for States to submit to the EPA CMD for all National Primary Drinking Water Regulations (NPDWRs) will improve the EPA's ability to fulfill oversight responsibilities under the Safe Drinking Water Act (SDWA).
