City council hears brine re-use, wellhead protection updates

The Glencoe City Council heard  two presentations from Short Elliot Hendrickson engineer Karen Cavett concerning the city’s water at the regular meeting Monday night.
Brine re-use
The first presentation was on the potential brine re-use project. The city first started looking into this project a year ago as a way to get the chlorides out of the water going to the wastewater treatment plant in order to meet the requirements for a new permit with the Minnesota Pollution Control Agency (MPCA).
Cavett said the new limit will be about 230 parts per million for chloride levels. The city’s current levels are about double that, she said.
The permit will be completed in two cycles. The first cycle is monitoring the levels for five years. Then the next cycle will be working to meet the limits.
The brine re-use project was a way to be proactive about the new permit, and remove the brine in order to help meet the new limit.
The study into brine re-use found that the city would be able to remove about 67,000 gallons of brine, but Cavett said that is only reducing the total chloride by 2 percent. It needs to be reduced 30 to 35 percent.
“So we’re not even getting close to where we need to be,” she said.
Cavett said because of this, brine re-use is not a viable option. She said it can still be a benefit for the city, but something more small-scale.
Mayor Randy Wilson asked if the brine is something that could still be sold to the county or state, but Cavett explained its much cheaper for them to make it on their own than to buy it from the city.
Cavett said there are lots of other treatment options and she and the city will look at how to meet the required levels.
