Guidance for Complying with the Lead and Copper Rule Revisions for Water Systems with No- to Low Prevalence of Lead Service Lines (LSL, LSLs)

Presently 15 to 22 million Americans nationally are served drinking water by lead lines. While most utilities employ effective corrosion control that limits the release of lead, the safest way to assure no lead release is to remove the source of lead. Given the recent attention from the public health community related to the potential impacts from lead in drinking water, it is understandable that USEPA is promoting Lead Service Line Replacements (LSLRs) in the Lead and Copper Rule Revisions (LCRR).

The objectives of this project are to develop guidance for utilities with limited lead lines to comply with the requirements of the LCRR pertaining to creating their lead service line inventories, as well as to compile and evaluate data and methods to better understand the extent of lead release from galvanized materials and from galvanized materials requiring replacement (GRR).
