All Drinking Water Contaminants Detected Below Regulatory Levels

The water in the Catalina Island Water System is a blended supply, with fresh groundwater sources located in the interior of the island and seawater processed by the desalination system located at the Pebbly Beach Generating Station.  The primary sources for the groundwater wells are located in Middle Ranch.

SCE is required to test for a number of different contaminants in the Catalina Island Water System, with the timing of the sampling varying based on the state's requirements. In order to ensure that drinking water is safe to drink, USEPA and California DPH prescribe regulations that limit the amount of certain contaminants in water provided by public water systems.

Drinking water contaminants detected during tests in 2013 are listed in the table at the link above as well as an explanation of terms and abbreviations. Note that the presence of the listed contaminants in water does not necessarily mean that the water poses a health risk and that all contaminants detected are below regulatory levels established by the DPH.
