Citing rising fears from scientists and utilities that traces of contaminants—such as antidepressants, antibiotics, birth-control pills, and cosmetics—may be entering water systems along the Front Range, state and federal officials are “ramping up” control efforts, reports The Denver Post. According to Kristen Keteles, a Denver-based EPA toxicologist, “current studies suggest [contaminants are] getting into the environment.” Areas of concern include Denver Water’s Dillon Reservoir, the South Platte River, and other locations being tested by the U.S. Environmental Protection Agency.

Meanwhile, in Keystone Tuesday, samples of local tap waters from around Colorado and Wyoming were part of a contest to find the area’s best-tasting H2O, writes the Summit Daily News. Each glass was given a score from one to 10, with one being the worst and 10 being the best. The rules prevented the judges (which included 5280 assistant editor Natasha Gardner) from knowing the source of the samples until the end of the contest.

Denver’s water stood out in the blind tasting, taking first place, which moves it into a national round of judging, notes the Fort Collins Coloradoan. Silverthorne came in second, and Aurora was third.
