Following the mandated Lead and Copper Rule sampling plan, Capital Region Water recently completed its required Lead and Copper Rule sampling plan by testing 45 high-risk residential homes throughout its service area in 2022. State and federal regulations require the 90th percentile lead level to be less than 15 parts per billion, meaning the lead level must not exceed this level in at least 90 percent of the homes sampled. Capital Region Water’s result was 0 parts per billion. Capital Region Water will test for lead and copper again in 2025.
