EPA Lead & Copper Rule

The U.S. Environmental Protection Agency’s (EPA) Lead and Copper Rule Revisions (LCRR) and Lead and Copper Rule Improvements (LCRI) represent major steps in the nation’s effort to reduce lead exposure through drinking water. These changes have significant implications for water treatment professionals, especially regarding the use of certified point-of-use (POU) devices. EPA Website

• Action Level: Remains at 15 parts per billion (ppb)
• New Trigger Level: Set at 10 ppb, requiring additional planning, monitoring, and treatment
• Lead Service Line Replacement (LSLR)

After any line disturbance (e.g., meter or gooseneck replacement), systems must provide a certified pitcher filter for up to 3 months and conduct a follow-up test.

Community Water Systems (serving ≥ 10,000 people)  and Non-Transient Non-Community Systems can elect the use of certified POU devices in place of corrosion control treatment. Requirements include:

• Must install at least one certified POU device per household or building
• Devices must be ANSI-certified to reduce lead
• Systems are responsible for maintenance, including filter changes and performance checks
• Monitoring: One-third of devices must be tested annually; all must be tested within a three-year cycle

• Advocate for the recognition of certified POU/POE devices as a viable compliance option
• Provide guidance and resources to members navigating LCRR and LCRI requirements
• Engage with EPA and other stakeholders to ensure the water treatment industry’s voce is heard
• Explore certified products for lead reduction
