Riverside Water Company
EWG's drinking water quality report shows results of tests conducted by the water utility and provided to the Environmental Working Group by the Colorado Department of Public Health & Environment, as well as information from the U.S. EPA Enforcement and Compliance History database (ECHO). For the latest quarter assessed by the EPA (July 2018 - September 2018), tap water provided by this water utility was in compliance with federal health-based drinking water standards.
Bromate is a carcinogenic disinfection byproduct formed when source waters containing bromide are treated with ozonation or sodium hypochlorite. Studies of laboratory animals show that bromate damages DNA and causes cancer in multiple organs. Click here to read more about disinfection byproducts.
How your levels compareThe State and National averages were calculated using the averages of the contaminant measurements for each utility in 2015.
ppb = parts per billion.
Health risks of bromate in excess of health guideline
The health guideline of 0.1 ppb for bromate was defined by the California Office of Environmental Health Hazard Assessment as a public health goal, the level of a drinking water contaminant that does not pose a significant health risk. This health guideline protects against cancer.
