Lead in Drinking Water

Minimizing lead and copper in drinking water has been a regulatory challenge ever since EPA published the Lead and Copper Rule (LCR) in 1991. The rule established a maximum contaminant level goal (MCLG) of zero for lead in drinking water and a treatment technique to reduce corrosion of lead and copper within the distribution system. Since 1991, EPA and states have taken action to increase compliance with the LCR, update the rule to reflect new research and best practices, and better protect public health. The most recent federal action is a major update to the LCR, finalized in January 2020, known as the Lead and Copper Rule Revisions (LCRR).

ASDWA Lead Service Line Inventory Framework

ASDWA worked with the Lead Service Line Inventory Workgroup to develop the State Implementation Framework for Lead Inventory Requirements under EPA’s Lead and Copper Rule Revisions (LCRR) and Template for CWS and NTNC Systems. The purpose of this framework and template is to provide useful and consistent information to primacy agencies, water systems, and consultants to start the development of lead service line inventories while EPA develops inventory guidance. The intent of this framework is to serve as a prequel for EPA’s Inventory Guidance and to ensure that everyone is working off the same information when starting inventories. The inventory template is intended to be used by states and water systems as a starting point for inventory development and data collection.
