According to CBS4, public testing data has found levels of perfluoroalkyl substances (PFAS), or forever chemicals, in Frisco’s drinking water that would be deemed as “too high” in Vermont, Massachusetts, and New York. The EPA recommends that drinking water not have more that 70 parts per trillion of PFOA and PFOS combined. Vermont, Massachusetts, and New York are among states that have started setting individual limits on PFAS. Vermont and Massachusetts have a limit of 20 parts per trillion for PFOA and New York has set a limit of 10 parts per trillion for PFOA. However, the Colorado Health Department testing that was conducted last summer found Frisco’s drinking water had more than twice the legal limit in those states. The Town of Frisco has said that there is currently no health concern because the PFAS levels are below the EPA’s health advisory level of 70 parts per trillion.
