Lead and Copper Rule



In 1991, EPA published the Lead and Copper Rule to minimize lead and copper in drinking water.  Minor revisions were made in 2000, 2004, and 2007.  The rule established a maximum contaminant goal of zero for lead in drinking water and an Action Level (AL) of 15 parts per billion for lead and 1300 parts per billion for copper based on the 90th percentile level of tap water samples.  An AL exceedance is not a violation but can trigger other requirements, such as increased monitoring, installation of corrosion control treatment, public education, and lead service line replacement.  The fact sheet for the LCR can be found on EPA’s website.

EPA revised the Lead and Copper Rule in 2021.  This rule is known as the Lead and Copper Rule Revisions (LCRR).  It improves the protection of children and communities from lead exposure by sampling schools and daycare facilities, removing lead service lines, and empowering communities through public education. The LCRR can be found at this link.  The LCRR establishes a compliance deadline of October 16, 2024, for water systems to complete their initial service line inventories. EPA announced on December 16, 2021, that they will begin developing a new regulation, the Lead and Copper Rule Improvements (LCRI), to strengthen key elements of the LCRR.  EPA plans to finalize the rule in the summer of 2024, and the estimated compliance deadline for the LCRI is the summer or fall of 2027, three years after the effective date of the rule.  More information on the LCRI can be found here.



The LCRR requires all community water systems and all non-transient, non-community water systems to complete an initial lead service line inventory (LSLI) by October 16, 2024. The inventory must include all service line connections, regardless of ownership, and be submitted using this template.  The template must be submitted to the Arkansas Department of Health, Engineering Section through the Engineering’s File Transfer Portal.





The Natural Resources Division of the Arkansas Department of Agriculture and the Department of Health Engineering Section have contracted with technical assistance providers to assist water systems with their service line inventories.  If you are interested in this assistance, please fill out the form below, and we will get in touch with you.  This offer is available to systems that serve populations under 50,000.  There is no cost for the service.
