Water purveyors take note: Drinking water Lead and Copper Rule revised
EPA has published final revisions to the National Primary Drinking Water Regulation (NPDWR) for lead and copper standards. Going into effect March 16 this year, but with compliance deadlines out three years (January 16, 2024), the revisions aim to improve effectiveness of the Lead and Copper Rule (LCR). Public water systems as well as non-transient, non-community systems (for example, those operating wells at commercial and industrial facilities providing potable water to its employees) may see changes from the new “trigger level” and other updates to the LCR.
Through the action, EPA is establishing a lead monitoring level (trigger level) at which actions will be required before reaching the maintained 15mg/L “action level.” When reached, the 10 mg/L trigger level will initiate progressively stronger actions that will reduce lead and copper exposure and improve corrosion controls. The rule revisions also create a new find and fix process that will kick in when individual tap samples exceed the lead action level. The rule revision also addresses a variety of elements to expand consumer awareness and increase water system public education.
As the Federal Register for this action points out, “the LCR is a complicated rule” and certainly this rulemaking doesn’t eliminate that. Rather it adds new layers of system management that water purveyors will need to become familiar with. If you are a drinking water system manager, take time to review the complete rule revision and understand implications on your system. Give yourself plenty of time to plan and budget for the January 2024 changes.
Key to remember: If your facility provides drinking water to employees via a well, you’ll want to pay attention to the new “trigger level” for lead monitoring.
