Monday the city of Hastings will start putting chlorine in the city’s water supply.
The decision comes after E.coli bacteria was found in the water system a few weeks ago.
The city says test results by the Minnesota Department of Health were unable to pinpoint an exact cause of the bacteria.
The state recommended the city find a permanent disinfection solution for the water supply, so Hastings will begin adding a low level of chlorine to the water.
"We want to make sure this doesn’t happen again," Hastings Mayor Paul Hicks said.
"We take this very seriously.
We decided to test our water every week.
We’re going to flush our system a little more frequently and we’re going to see how this chlorination system goes."
Despite fears by some of how chlorine will change the taste and smell of the water, the city says it’s perfectly safe.
The city will monitor the water supply for the next few months to see if they’ll continue using chlorine in the water supply.
