Bainbridge Island Aquifer System, WA

In March 2013, EPA designated the Bainbridge Island Aquifer System in Kitsap County, Washington a sole source aquifer.  The Federal Register Notice was published on March 29, 2013.  A sole source aquifer is an underground water supply designated by EPA as the sole or principal source of drinking water for an area.  The system EPA designated encompasses the entire Bainbridge Island area and is made up of six principal aquifers.  One hundred percent of the current population on Bainbridge Island obtains their drinking water from the designated aquifer.  There are no other sources of drinking water nearby that would be economically feasible to supply all residents in the area.
