The Environmental Protection Agency (EPA) introduced the Lead and Copper Rule (LCR) to protect the safety and quality of drinking water. This regulation required community water systems (CWS) to create inventories of lead service lines (LSLs) by the compliance deadline, which has now passed. If your system has not yet met these requirements, it is critical to act promptly to ensure compliance and protect public health.
Established in 1991 as part of the Safe Drinking Water Act (SDWA), EPA’s primary objective with the LCR is to protect public health and reduce exposure to lead in drinking water.
So, what do you need to know, and what steps do you need to take to protect your community from lead exposure and meet the EPAs goal of complete lead service line removal? This article provides essential details, highlights available funding resources, and outlines the steps to follow to help ensure the safety of your residents by eliminating all lead service lines and providing clean and healthy drinking water for all.
Timeline of EPA Lead and Copper Rules:
States may have stricter drinking water regulations than the EPA. Check your state for more information.
The LCRR specifies requirements of the initial inventory to include:
Material classification. Each service line, including portions with split ownership, must be classified as lead, galvanized requiring replacement (GRR), non-lead, or lead status unknown.
All service lines and ownership. The inventory shall include both the system- and customer-owned portions of all service lines within the distribution system.
Information to identify material. Service line materials shall be classified using previous materials evaluations, construction and plumbing codes/records, water system records, distribution system inspections and records, information obtained through normal operations, and state-specified information.
Initial inventory submission and updates. Submit your initial inventory to the appropriate regulatory agencies to comply with the Lead and Copper Rule requirements. Water systems that demonstrated the absence of LSLs by the stated October 16, 2024, deadline are not required to provide an update. However, if these systems subsequently find any LSL or GRR service line, they have 30 days to notify the state and prepare an updated inventory on a schedule established by the state. Afterward, inventories must be updated and submitted to primacy agencies annually or triennially, depending on lead tap sampling frequency, but not more frequently than annually.
Public accessibility. Inventories shall be made publicly available and include a locational identifier for LSLs and GRR service lines. Water systems serving more than 50,000 people must provide inventories online.
Consumer confidence report (CWSs only). CWSs must inform the public how to access the service line inventory information through their consumer confidence report.
Service line consumer notification. Notification must be provided to individuals served by the water system at the service connection with an LSL, GRR, or lead status unknown service line. For water systems serving communities with many non-English speaking consumers, as determined by the state, public education materials must be in appropriate languages or contain a telephone number or address where they may contact the water system to obtain a translated copy of the materials or to request assistance.
Notification must be provided within 30 days after completion of initial inventory and repeated annually until only non-lead lines remain. Water systems must also provide this notice for new customers during service initiation. Notice must include a statement about service line material, lead health effects, and steps to minimize lead exposure in drinking water. If the service line is:
Notification delivery must be by mail or by another method approved by the state. The water system will need to report that the notification was delivered and provide a copy of the notification and information materials to their states annually by July 1 for the previous calendar year.
Building an LCRR-required service line inventory is a systematic process that SEH can simplify for you. Below are five steps to build and create your inventory.
Removing LSLs from drinking water systems can be costly for communities or water utilities. Funding options are available at the federal and state levels. Here are some sources to consider.
