Introduction to Lead Service Line Inventory

Lead Service Line Inventory can be used to develop a lead service line inventory and monitor the replacement of service lines required to comply with the Environmental Protection Agency's (EPA) Lead and Copper Rule Improvements.

Replacing lead service lines is the best way to reduce the risk of exposure to lead in drinking water across a community. Water utilities are required to create and maintain a lead service line inventory under the Lead and Copper Rule Improvements (LCRI). Having authoritative information about the number and location of lead service lines is the first step in creating a lead service line removal program to safeguard the health of the community. Lead service line inventory is typically implemented by water utilities that want to maintain an authoritative lead service line inventory to support replacement and monitoring activities in compliance with federal regulations.

The Lead Service Line Inventory solution delivers a set of capabilities that help you inventory lead service lines, validate service line materials in the field, monitor replacement activities and regulatory compliance, capture water sample information, and share information with the public.
