CVWD recently completed a full-scale demonstration project 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 anticipated future chromium-6 drinking water standards set by the state. The stannous chloride treatment option is substantially less expensive and has less impact to the community and the environment than other methods.
