Drinking Water Laboratory Analysis Results 2011
2011 monitoring results. The California State Water Resources Control Board (CASWRCB) Division of Drinking Water (DDW) regulates approximately 7,500 public water systems throughout the State of California. Part of this regulatory oversight ensures that required water quality sampling has been conducted and that follow-up actions are taken when the concentrations of certain chemicals exceed set limits. To streamline its regulatory oversight, DDW launched a portal known as CLIP (California Laboratory Intake Portal) on September 1, 2021. This change to the electronic submission of water quality analyses replaces the WQM (Water Quality Management) portal and ensures that data from laboratories flow to DDW’s database of record, the Safe Drinking Water Information System (SDWIS). This process will not only allow for quicker compliance determinations but will also provide for improved data quality by ensuring that minimum data validations have been met. Notice to the users of the data - use care in interpreting the data. A single detection of a contaminant may not indicate contamination of a drinking water supply. If this detection is not confirmed with a follow-up detection, it may represent a false positive. Additionally, the presence of a contaminant in raw water at a given concentration does not necessarily mean that the water was served by the water system to its customers, or if served, that the contaminant was present at that concentration. Water systems may not use certain sources or may treat or blend them prior to service.
