All community water supplies must develop a Lead Service Line Inventory and submit it to the Iowa Department of Natural Resources (Iowa DNR). The inventories are due October 16, 2024.  IAMU has dedicated staff to help you understand the process and answer questions you might have.

Why do we need to do a Lead Service Inventory?  To assess the extent of lead service lines in your community, identify better sampling locations, begin planning for Lead service Line replacement which includes applying for state and federal grants (The BIL Bipartisan infrastructure Law provides 15 Billion for lead service line replacement) and, it’s required by the EPA.

The EPA has posted more helpful information on their website recently. Here are links to some resources that you might find helpful.

If you haven’t done so already, download the appropriate template for your municipality and take a look at it.

If you are a system who has less than 10,000 service lines, please use the Iowa Lead Service Line Inventory Small File (3,5 MB).  If you are a system who has 10,000 or more service lines, please use the Iowa Lead Service Line Inventory Large File (57.7 MB).  The Iowa Lead Service Line Large File (57.7 MB) may take a few minutes to download.

Please email LCRR@dnr.iowa.gov if you are unable to open the Excel file.
