Key Takeaways Using records research, geospatial analysis, and focused customer outreach, Cal Water's pilot program improved the accuracy of its Lead and Copper Rule (LCR) sample‐site selection. Following best practices to review and update a system's sample‐site selection program can ensure that lead‐and‐copper data reflect high‐risk sites. Effective lead‐and‐copper sampling plans allow water utilities to make critical corrosion‐control and water quality improvement decisions to protect public health. Updating LCR sampling plans will be necessary for continued compliance with the forthcoming LCR Revisions.
