In 2021, U.S. EPA adopted the Lead and Copper Rule Revisions (LCRR) which require public water systems to perform additional actions to better protect communities from exposure to lead in drinking water. One of these actions requires public water systems to complete a Lead Service Line Inventory (LSLI) of all lines in their system, including the portions owned by the utility and the customer.

The Indiana Department of Environmental Management required public water systems to submit LSLI’s to IDEM by October 16, 2024. Additional provisions that took effect on October 16, 2024 are annual communication by the utility to homes connected to lead service lines, and additional requirements for public notification and a lead action level exceedance.

Additional information can be found at IDEM’s Drinking Water and Lead website.
