The city of Blaine caused dozens of private wells to run dry last summer after wrongfully pumping hundreds of millions of gallons of water from three wells without a permit, a state investigation found.
The Minnesota Department of Natural Resources announced the findings Tuesday after a monthslong investigation into 50 complaints from homeowners who temporarily lost water during the height of the 2022 drought. The city's pumping was the main reason that 47 of those homes lost water, the DNR found.
Another 27 complaints from private well owners who lost water are still under investigation.
"This is the largest number of complaints in one investigation that the state has done," said Randall Doneen, DNR conservation assistance and regulation section manager. "It speaks to the challenge of a growing community trying to develop a treated sustainable water supply when the neighboring community is almost all private wells."
The city will have 60 days to work out settlement agreements with each of the private well owners — those settlements typically cover the cost of the work it took to restore water to a home.
"We're looking at how we can move forward to make this right for everybody," said Dan Schluender, Blaine's city engineer.
The costs for well owners varied, from a few hundred dollars to a little more than $6,000, depending on how much work was needed. All together, the 47 well owners spent $97,000 lowering pumps, drilling deeper wells or doing other work to get water back in their homes, according to the DNR.
The number of households that lost water is unprecedented in Minnesota. The DNR typically receives five well interference complaints in a year.
