Water Plant Operator Steve Zaborowski collects a water sample for radium testing at the city's Johnson Street water plant. The city recently installed a new system to remove radium, following multiple test results over the federal health limit.
Winona adds treatment to fix radium in drinking water
(4/28/2021)
Although the Mississippi River flows next to Winona, the water that pours from your faucet doesn’t come from there. It comes from deep underground, out of natural storage in the Mount Simon aquifer, a great deal cleaner than the river.
It’s also sometimes slightly radioactive, and tests from earlier this year showed the radioactivity in the city’s water exceeded federal standards.
