Lead and Copper Rule Improvements (LCRI)

A set of enhancements to the 2021 Lead and Copper Rule Revisions (LCRR), enacted on October 8, 2024. The LCRI requires all water systems nationwide to fully replace lead service lines (LSLs) by 2037, lowers the lead action level to 10 parts per billion (ppb), and strengthens requirements for lead testing and public communication about lead in drinking water.

    Milwaukee is one of the few cities in the country with a prioritization plan to ensure neighborhoods likely to suffer the most severe impacts from lead poisoning get their pipes replaced first. In consultation with a community-based group, Coalition for Lead Emergency (COLE), and following a public engagement process, Milwaukee included in an ordinance three indicators to prioritize where LSLs will be removed first:

    1. The area deprivation index (ADI), which is a compilation of social determinants of health
    2. The percentage of children found to have elevated lead levels in their blood when tested for lead poisoning
    3. The density of lead service lines in the neighborhood.
