Chromium-6 Stannous Chloride Demonstration Project

CVWD completed a full-scale demonstration project in 2017, using stannous chloride treatment for the water system serving Indio Hills, Sky Valley, and some areas in and around Desert Hot Springs. The project successfully reduced Cr-6 to Cr-3 using stannous chloride, an approved drinking water and food additive. Because of this testing, CVWD is prepared to meet the state's anticipated future chromium-6 drinking water standards. The stannous chloride treatment option is substantially less expensive and impacts the community and the environment less than other methods.
