Lead and Copper
Presentation 1—Lead and Copper Rule Revision (LCRR) (Presented by Anne Lausier and Iliriana Mushkolaj, EPA's OW). EPA’s new Lead and Copper Rule Revision (LCRR) strengthens every aspect of the Lead and Copper Rule to better protect children and communities from the risks of lead exposure. The rule aims to better protect children at schools and childcare facilities, get the lead out of our nation’s drinking water, and empower communities through information. This presentation will provide the technical details of the LCRR.
Presentation 2—Chemistry of Lead Corrosion and Release (Presented by Simoni Triantafyllidou, EPA's ORD). Corrosion and solubility control the release of lead from legacy lead pipes and other leaded plumbing material into drinking water. Key water quality parameters, such as pH, alkalinity, dissolved inorganic carbon, disinfectants, and corrosion inhibitors, interact with leaded materials in complex ways. This presentation will provide the basic principles of lead corrosion/solubility and updates to practical understanding based on technical support efforts.
Presentation 3—Copper Corrosion: Copper Release to Pitting Attack (Presented by Darren Lytle, EPA's ORD). The release of copper from distribution materials is an important issue for drinking water systems from a health and regulatory perspective. Furthermore, the problem of excessive localized or pitting corrosion is typically not associated with elevated copper levels or regulatory considerations but can be a major financial burden and inconvenience to homeowners. This presentation will discuss factors that influence both copper corrosion concerns and present strategies to minimize each.
