Starting today, the vast majority of Americans can learn about every potentially harmful chemical in their drinking water and what scientists say are the safe levels of those contaminants thanks to the Environmental Working Group. EWG’s new national Tap Water Database is the most complete source available on the quality of U.S. drinking water, aggregating and analyzing data from almost 50,000 public water systems in all 50 states and the District of Columbia
The study found that virtually all public water systems in the United States have some sort of pollutant in them. The detailed report found 92 pollutants in the 875 water utilities in the state of Kansas and found three contaminants detected above health guidelines in the city of McPherson. This sample is from the latest quarter of assessment for the EWG (January through March of 2017).
The report lists that most pollutants come from naturally occurring elements as well as treatment byproducts and agriculture, but it also found that some of the pollutants can be linked to industry and water runoff.
Most importantly, the water in McPherson was not in violation of health-based drinking water standards, but the pollutants, like in nearly every other US city, were there.
