Important Information about Your Drinking Water


In May 2016, the United States Environmental Protection Agency (EPA) issued a lifetime Health Advisory (HA) of 70 parts per trillion (0.070 ug/L) for a combination of two Per and Polyfluoroalkyl Substances (PFAS). Although we are not required by EPA to routinely monitor for PFAS, we began sampling for PFAS in September 2016. All of our PFAS test results for our treated water were below the EPA advisory level, including our last sample that was taken on March 7, 2018.  For more information about PFAS, click here
