Catalina Island Customers - 2007 Consumer Confidence Report

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. As water travels over the land surface or through the ground on its way to the groundwater sources, it dissolves naturally-occurring minerals and, in some cases, radioactive material, and can pick up substances resulting from the presence of animals or from human activity.

The primary sources for the groundwater wells are located in Middle Ranch Canyon. As part of our continued management of the drinking water system, SCE conducted source water assessments of the groundwater that were completed in June 2002 and December 2002. Seawater source assessments were completed in June 2003. These source water assessments indicate that fresh groundwater sources are considered most vulnerable to the following influences: septic tanks, grazing animals and poorly constructed or abandoned wells in the aquifer. The seawater well watershed contains few contaminant sources and most will not significantly affect the quality of ocean water pumped.
