Consumer Confidence Reports (CCRs)
The preparation of CCRs is required by Health & Safety Code §116470 and California Code of Regulations, Title 22, Article 20. Health & Safety Code §116470(b) also requires public water systems with more than 10,000 service connections that detect contaminants above their public health goals (PHGs) to provide PHG exceedance reports every three years and to hold public hearings regarding their reports.
The 2020 CCR should cover water quality data from January 1, 2020 through December 31, 2020. The 2020 CCR must be completed and distributed to consumers by July 1, 2021. Certification that you completed your 2020 CCR and provided it to consumers must be submitted to the Division of Drinking Water (DDW) District Office (PDF) or Local Primacy Agency (LPA) that regulates your water system by October 1, 2021.

Note: Because the Hexavalent Chromium MCL Regulation was withdrawn on September 11, 2017, water systems were not required to monitor for this contaminant in 2020. However, DDW recommends, but does not require, that any hexavalent chromium results collected by a water system in 2020 be reported in its 2020 CCR.
