Lead Service Line Inventory

The Missouri Department of Natural Resources (MDNR) is helping Missouri's water systems develop an initial lead service line inventory. An inventory is required for all community and non-transient non-community water systems. The water system is required to submit an initial inventory to the department on or before Oct. 16, 2024.


MDNR has developed various documents and other media that focus on specific information, which are located on their website.
