The Lead and Copper Rule Revisions White Paper provides examples of regulatory options to improve the existing rule. The paper highlights key challenges, opportunities, and analytical issues presented by these options. Options include lead service line replacement, improving optimal corrosion control treatment requirements, consideration of a health-based benchmark, the potential role of point-of-use filters, clarifications or strengthening of tap sampling requirements, increased transparency, and public education requirements.
Lead and Copper Rule Long-Term Revisions
Lead exposure occurs through many pathways, including soil, dust, food, and drinking water. Through a series of policies – including the phase-outs of lead in gasoline and paint – the U.S. has made major progress in reducing lead exposure and childhood blood lead levels over the past several decades. Although the LCR has resulted in substantial reductions in lead in drinking water, there is a compelling need to strengthen its public health protections and clarify its implementation requirements.
