JEO Helping Communities Get the Lead Out

The Environmental Protection Agency (EPA) rolled out new regulations for its existing Lead and Copper Rule (LCR) policy. These updates require public water systems to complete an inventory of all water service lines within their jurisdiction to help identify lead service lines. This information will be useful to public water systems as they plan for long-term replacements of those lines. It is important for public water systems to understand all the requirements that fall under this policy, which include public outreach, engagement, and education, as well as conducting and maintaining a service line inventory.

Initial Inventory Requirement (Deadline 10/16/24)

Under the EPA’s Lead and Copper Rule Revisions (LCRR), public water systems were required to submit their initial lead service line inventory to state primacy agencies by October 16, 2024. This inventory identified the material of service lines throughout each system.

Upcoming RequirementS And Deadlines

Baseline Service Line Inventory Update – Due November 1, 2027

Public water systems must update their service line inventories to include connector materials. Connectors must be classified as Lead, Non-lead, Unknown, or None. Inventories should also include an address/location ID (if available) and report totals for service line types, lead and unknown connectors, and lead or galvanized requiring replacement (GRR) service line replacements.

Public water systems should also be working to verify and remove as many unknown service lines and connectors in their inventories prior to the November 2027 deadline as possible. Unknown service line materials and connector materials must be verified and proven not to be lead or galvanized requiring replacement materials before they can be removed from the inventory and the requirement to investigate and/or replace.

Unknown service lines in a PWS inventory will also trigger specific sampling, notification, and replacement mandates according to the EPA regulation. Under the current regulation, ‘unknown’ lines are presumed lead until proven otherwise.

Service Line Replacement Plan – Due November 1, 2027 (if applicable)
Systems with lead, GRR, or unknown service lines must develop a service line replacement plan outlining annual replacement rates and prioritization strategies.

Long-Term Compliance Timeline

• Nov 1, 2027 – Submit Baseline Service Line Inventory and Replacement Plan (if applicable).
• Within 30 days – Provide initial public notification of service line material and annually thereafter.
• At service initiation – Notify new customers of service line material.
• Jan 30, 2029 – First annual inventory update due; then annually thereafter.
• Dec 31, 2034 – Complete inventory validation of non-lead service lines.
• Jan 30, 2035 – Final validation report due.
• Dec 31, 2037 – Complete full lead service line replacements.
• Jan 30, 2038 – Final replacement report due.

*Dates reflect EPA timelines. Deadlines may vary by state. Individual states may have additional and varying deadlines of their own.

Leading the Way

Understanding the Lead and Copper Rule: What Communities Need to Know and Do

The updated Lead and Copper Rule requires communities to identify, track, and replace lead or potentially lead-contaminated water service lines, especially in properties built before 1987.

Strict deadlines are in place: initial inventories (2024), baseline inventories and replacement plans (2027), and full replacement of lead lines by 2037, with ongoing annual inventory updates starting in 2029.

The process can be complex and costly, but federal funding (including $15B from the Bipartisan Infrastructure Law) is available to support compliance.

Successful implementation depends on strong community engagement, accurate data collection, and coordinated planning, often requiring expert support to manage inventories and large-scale replacements.

Experience in both Inventorying and Replacements

Since 2022, JEO has been working with communities of all sizes to help identify the lead-contaminated pipes that connect water mains to homes and businesses. We’re already helping communities replace them with safer materials.
