EWG's drinking water quality report shows
results of tests conducted by the water utility and provided to the Environmental Working Group by the Minnesota Department of Health - Environmental Health Division, as well as
information from the U.S. EPA Enforcement and Compliance History database (ECHO). For the latest quarter assessed by the U.S. EPA (January 2021 - March 2021), tap water provided by this water utility was in compliance with federal health-based drinking water standards.
Radium is a radioactive element that causes bone cancer and other cancers. It can occur naturally in groundwater, and oil and gas extraction activities such as hydraulic fracturing can elevate concentrations.
Radium, combined (-226 & -228) was found at 52 times above EWG's Health Guideline.
EWG Health Guideline
0.05 pCi/L or less
This Utility
2.6 pCi/L
Legal Limit
5 pCi/L
National Average
0.46 pCi/L
State Average
1.24 pCi/L
The state and national averages were calculated using the averages of the contaminant measurements for each utility in 2014-2019. pCi/L = picocuries per liter
Health Risks
EWG applied the health guideline of 0.05 pCi/L, defined by the California Office of Environmental Health Hazard Assessment as a public health goal for radium-226, to radium-226 and radium-228 combined. This health guideline protects against cancer.
Includes chemicals detected in 2017-2019 for which annual utility averages exceeded an EWG-selected health guideline established by a federal or state public health authority; radiological contaminants detected between 2014 and 2019.

One of the best ways to push for cleaner water is to hold accountable the elected officials who have a say in water quality – from city hall and the state legislature to Congress all the way to the Oval Office – by asking questions and demanding answers.
