Community water systems of all sizes will be be taking a number of steps to prepare to comply with the Revised Lead and Copper Rule. The Revised LCR includes several different types of sample collection beyond what is required by the current rule. Importantly, Tier 1 sample sites (i.e., homes lead service lines) will require "fifth-liter" samples. The new requirements will also require re-thinking current compliance sample sites, as well as, developing sample protocols for follow-up samples at sample sites with lead levels above 15 µg/L and homes where there have been lead service line replacements. Monitoring in schools is also a feature of the rule revisions. This webinar focuses on key steps water systems can take now in preparation for compliance with the rule requirements in 2024.
