The Environmental Working Group reviewed Iowa’s tap water this month and found dozens of contaminants across the state. However, most of Iowa’s water systems are compliant with federal regulations.
The organization, which is based in Washington, D.C., released its review last week. The review looked at several utilities that produce water in Iowa and found that most have unsafe levels of multiple contaminants. According to Iowa Capital Dispatch, the group is also calling for stricter standards for water quality across the country.
Director of the Center for Health Effects of Environmental Contamination at the University of Iowa David Cwiernty told the Dispatch it is impossible to treat water so it will have no contaminants and the current regulatory framework runs on the basis of “an acceptable level of risk.”
Some of the contaminants in the review were found above the legal limit in a few systems, including radium and arsenic. The group also has an online database where people can check their water by zip code for potential contaminants. According to its website, the Iowa City Water Department has 19 total contaminants. Some of the contaminants included nitrates, trichloroacetic acid, and strontium. It was not one of the systems where excessive amounts of radium or arsenic were found.
