Welcome to CDM Smith.

What do the EPA's Lead and Copper Rule Revisions mean for your water system?

The final Lead and Copper Rule Revisions (LCRR) will be published this year, which marks the first major revision to the original 1991 Lead and Copper Rule (LCR). The LCRR includes some major changes that will impact most water systems. Although the general require­ments are the same for all water systems, the specific details will change depending on your system’s size, type of corrosion control, what service line materials you have in your system and your current 90th percentile lead levels.

Complete the two-minute questionnaire below for a customized report based on your unique water system. This tool focuses primarily on requirements for community water systems managing lead corrosion since the LCRR heavily focuses on lead over copper. If your system exceeds or is approaching the copper action level of 1.3 mg/L, if you are a non-transient, non-community water system, or if you are faced with another scenario that is not covered by this tool, please contact us at water@cdmsmith.com for specific guidance.


These guidelines are based on the Federal Lead and Copper Rule (LCR). Please check with your respective state or primacy agency for any additional requirements.

As of March 10, 2021, the EPA is requesting additional public input on the Lead and Copper Rule Revisions and has extended the effective date to at least June 17 and potentially December 16. This may push the compliance date back from January 2024 to September 2024.
