EPA Administrator Lee Zeldin said the new distribution reflects the agency’s effort to ensure funding is “properly distributed to achieve maximum impact” as utilities move into the next planning cycle. Improved inventories now allow the agency to “tackle this challenge more efficiently than ever before,” he said in the announcement.

The revised national estimate stems from the first full round of service-line inventories required under federal Lead and Copper Rule Revisions. 

Those inventories were due Oct. 16, 2024, and EPA spent the past year analyzing state submissions. The updated data—now presented in a public dashboard—shows about 4 million lead service lines nationwide, down from the prior 9.2 million estimate that existed before mandatory reporting.

Water Infrastructure Experts Urge Senate to Reauthorize IIJA to Fund Major Upgrades

Recent analyses of EPA-reported data show wide geographic variation in documented lines, with states such as Illinois, Ohio, Pennsylvania and Florida reporting some of the highest known concentrations.

EPA Assistant Administrator for Water Jess Kramer said the sharper data picture means the $3 billion “will go farther” because utilities “are identifying fewer lead pipes than previously believed,” the agency said.

Funding will be distributed through the Drinking Water State Revolving Fund’s lead service line replacement program created under the Infrastructure Investment and Jobs Act. 

It can support locating, planning, design and full replacement of lead service lines. EPA also released a memorandum outlining additional flexibilities states may use when deploying this appropriation.

States that have not obligated or spent funds dating back to fiscal 2023 must submit updated plans explaining how they will deploy those awards before qualifying for additional allocations. 

Under the Safe Drinking Water Act, EPA is required to redistribute unused SRF dollars, and the agency said it will work with slower-moving states to ensure money is promptly directed to systems with documented replacement needs.

A Thirsty Public

Environmental and public-health groups largely welcomed the recalibration. Clean Water Action said the decision to tie allocations to updated inventories is “a common-sense and welcome improvement” that helps direct federal support to communities with the clearest replacement needs.

The Natural Resources Defense Council has described the broader federal lead-pipe replacement framework as a significant step toward safer drinking water, noting that more precise inventory data strengthens implementation and oversight.

Water-sector organizations also responded as EPA shifted dollars based on verified data. The American Water Works Association reiterated its support for removing all lead service lines as quickly as feasible, while emphasizing that full funding—particularly for portions located on private property—remains essential for equitable and workable implementation.

Regional officials framed the corrected inventories as key to funding fairness. The Great Lakes and St. Lawrence Cities Initiative commended EPA’s use of updated state data, saying the revised allocation approach helps ensure Great Lakes states receive an appropriate share of federal lead service line replacement funding.

EPA’s action comes as utilities refine their maps of remaining lead lines and prepare multi-year capital plans. 

The Seventh Drinking Water Infrastructure Needs Survey estimates $625 billion in drinking-water infrastructure needs over 20 years, including extensive pipe replacement. 

With replacement obligations and inventory reporting deadlines continuing into 2026, the refined state data and updated funding distribution are expected to influence upcoming project pipelines as utilities adjust intended-use plans and develop new bid packages.
