Although the 90th percentile tap samples lead action level is rarely exceeded by California public water systems, some of the individual tap samples have exceeded the action level. To maintain high confidence in the drinking water that the City of Pismo Beach provides its customers, the City is enhancing our public outreach efforts and the availability of LCR compliance- related information. The State Water Resources Control Board, Division of Drinking Water (DDW) has recommended that all public water systems make the following information available to maintain our customer’s confidence:  The latest 90th percentile values for the most recent round of LCR tap sampling o Copper = 190 PPB o Lead = 0.9 PPB  The number of sites sampled, the number of sites that exceeded an action level, and the number of samples that were invalidated (if applicable) o 21 samples o 1 sample was invalidated  Justifications for invalidation of LCR samples (if applicable) o 1 invalidated sample was found due to improper hold time in the customer’s home plumbing (more than 6 hours). This sample was retested per SWRCB’s recommendation and showed to be below the action level.  Information on the locations of lead service lines in the distribution system, together with a map of the identified areas and an inventory of lead plumbing in the system o No known lead service lines in the City of Pismo Beach’s distribution system  Additional health information on how to minimize lead in drinking water if lead was detected above the action level in more than 5%, and up to and including 10% , of sites sampled. o The City of Pismo Beach has not detected lead above the action level in more than 5% of sample sites.
