EPA Office of Ground Water and Drinking Water Director Peter Grevatt issued a new memorandum to state water division directors and EPA regional offices “to improve primacy agency oversight of the selection of sample sites and monitoring frequency by public water systems” under existing Lead and Copper Rule ((LCR) regulatory requirements. The memo emphasizes the need for rigorous evaluation of the process used to select tier 1 sampling locations as well as maintaining and updating documentation from required material evaluations used to make those selections. Additional scrutiny of the process for determining eligibility for triennial monitoring is also recommended, including further evaluation of corrosion control practices and historical performance , as well as the technical, managerial and financial capacity of the system.
This memo is the latest in a series of communications from EPA to bolster LCR implementation and compliance while working on regulatory revisions expected to be proposed in 2017. Links to all EPA outreach materials and other resources are available through AMWA’s Lead Resources webpage.
