The U.S. Environmental Protection Agency (EPA) has announced improvements to the availability and usability of drinking water data in the Enforcement and Compliance History Online (ECHO) tool. ECHO now allows the public to search to see whether drinking water in their community met the standards required under the Safe Drinking Water Act (SDWA), which is designed to safeguard the nation’s drinking water and protect people’s health. SDWA requires states to report drinking water information periodically to EPA.
