LCRI: A Shift To Mandatory Service Line Replacement Within 10 Years

The EPA’s Lead and Copper Rule Improvements (LCRI), effective October 2024, mandates a shift from optional to mandatory lead service line (LSL) replacements across U.S. water systems, with a target completion within 10 years. Unlike prior rules which triggered replacement only when lead levels exceeded certain thresholds, LCRI requires full LSL replacements, aiming to reduce lead exposure risks comprehensively. This proactive approach addresses significant public health concerns by prioritizing swift action on high-risk lines and ensuring stricter compliance. However, it poses financial and logistical challenges for utilities, which may require support to meet these ambitious targets.

This article will explore some of the key differences and implications when it comes to LCRI and LCR regarding mandatory service line replacement.
