Data show that from 1976 – 1980 the median blood lead level of a child (1-5 years old) was 15 micrograms per deciliter. Those levels have been dramatically reduced since then, to 1 microgram per deciliter, based on the most recent data. These major improvements were made over the past several decades by removing lead from toys and lead solder in cans, taking lead out of gasoline, reducing exposure to lead in paint and dust in homes and during renovations, greatly reducing the allowable content of lead in plumbing materials in homes and other buildings, and further reducing lead in drinking water through the federal Lead and Copper Rule. Although we have taken significant steps to protect our children from the detrimental effects of lead poisoning, there’s more to do.
To further reduce exposure to lead from drinking water, EPA recognizes the need to strengthen and modernize the Lead and Copper Rule, which is now 25 years old. EPA has been working intensely to develop proposed revisions to the LCR, and we expect to propose a rule in 2017. With that in mind, EPA is releasing a White Paper on the Lead and Copper Rule Revisions to ensure that stakeholders are informed of the options that EPA is considering as part of the rulemaking process. This paper provides examples of regulatory options that EPA is evaluating and highlights key challenges, opportunities, and analytical issues presented by these options. EPA expects the paper will help facilitate our ongoing engagement with stakeholders and the public as we work to develop a proposed rule.
