The Department of Health routinely tests Puget Sound water in the area surrounding U.S. Navy facilities at Bremerton and Bangor. Water is measured for radioactivity, including cesium-134 (Cs-134), cesium-137 (Cs-137), and iodine-131 (I-131). Below are test results from 2013, 2014, and beginning of 2015. All test results show there is no health risk.
