This article discusses the on‐going process of replacing lead service lines (LSLs) by utilities across the country in an effort to minimize consumers' exposure to lead from drinking water. Because of issues described in the article, many utilities have authority to replace only the portion of lead service piping they own (partial replacement from main to curb stop) instead of full replacement from main to residence. This has caused debate as to how effective partial replacement programs are for meeting the Lead and Copper Rule requirements. The article cites two studies done by the Greater Cincinnati Water Works on lead level spikes, and discusses a 2007 analysis of LSLRs (partial and full) that provides a better understanding of short‐ and long‐term benefits and effects associated with these replacements. The article includes an inset by Greg Pierson and Ron English titled, “End‐use Plumbing Components Elevate Lead Levels in Seattle Public Schools”.
