Minnesota warning as springs polluted with pesticides, analysis reveals


Pesticides have been found in high concentrations in ground and surface water sources in Minnesota, not only posing a risk to local wildlife but possibly also contaminating drinking water for many of the state’s residents.

In a new study, published in the journal Science of the Total Environment, Arnold and colleagues from the University of Minnesota Twin Cities in collaboration with the Minnesota Department of Natural Resources collected water samples from 15 natural springs and 75 unique wells across 13 Minnesota counties between 2019 and 2022. Samples were included from both urban and rural areas as well as water sources at various depths.

What they found was that water in natural springs were particularly susceptible to contamination with these insecticides.

Over 450,000 tons of pesticides are used in the U.S. every year, according to data from the Food and Agriculture Organization of the United Nations. Not only can these chemicals seep into surrounding ecosystems and affect plants and animals, but they may also harm human health.

The health impacts of these chemicals depend on the types of pesticide used, but several common agricultural chemicals have been associated with developmental and hormonal disruptions, as well as neurotoxic effects. Other studies have suggested that exposure to these chemicals may be as bad as smoking when it comes to increasing our risk of certain types of cancers. However, it is unclear how much exposure is required to see these effects.

Insecticides are a class of pesticide that target insects in both agriculture and urban pest control. Due to their widespread nature, these chemicals not only end up as residues on our food, but can also get swept away into surrounding lakes, rivers, and groundwater systems.

“We use so many of these chemicals in Minnesota. Basically, every corn and soybean seed is treated before planting,” Bill Arnold, a professor in the University of Minnesota’s Department of Civil, Environmental, and Geo- Engineering, said in a statement. “Many of these chemicals can be purchased at a local hardware store that can be used for spraying fruit trees, flea and tick control for your pets, and eliminating bedbugs.”

“We were surprised by the high levels of the chemical detected in the natural springs and in some cases the chemicals were observed at much deeper levels in wells than we expected going into this project,” Arnold said.

“Oftentimes people think a natural spring has water that is safe to drink. That’s not necessarily true, it depends on how deep that water is sourced.”

In light of these findings, the research team is working with county and state agencies to include insecticides in water treatment monitoring lists and to improve the treatment of stormwater in urban environments to facilitate the removal of the chemical pollutants.

5 tornadoes confirmed in Friday’s outbreak in southeastern Minnesota


The National Weather Service confirmed that at least five tornadoes touched down in southeastern Minnesota on Friday, including four that hit Olmsted County. At least another three twisters were confirmed in southwestern Wisconsin.

The NWS was still analyzing data and other information to determine if more tornadoes occurred in the area.

The storms started Friday afternoon, with the first tornado touching down north of Sargeant in Mower County around 1:45 p.m. The short-lived EF0, with top wind speeds of 80 mph, traveled about 3 miles northeast into rural Dodge County near the unincorporated town of Oslo. It lasted for about five minutes in total, the weather service says, and caused minor damage to a grain silo before dissipating.

A new tornado formed a few minutes later, less than a mile away south of Oslo. The storm was also considered an EF0, with wind speeds around 80 mph. Lasting less than 10 minutes, it traveled 4 miles into Olmsted County, causing light damage to farm outbuildings and trees.

The line of storms seemed to pick up intensity as it entered Olmsted County.

Around 2:17 p.m., the EF2 tornado that would later hit Marion Township first touched down just northeast of Stewartville. The weather service estimates that the twister had wind speeds of about 130 mph and traveled nearly 10 miles northeast, before dissipating around 2:31 p.m. Multiple homes were severely damaged with roof removal and partially collapsed exterior walls.

An EF1 tornado was also confirmed to have hit near Potsdam around 2:30 p.m.

The first portion of the tornado was weak, the weather service said, with mainly EF0 damage. On the second portion of the 12-mile track, the tornado intensified to produce approximately 100 mph winds with tree and farm outbuilding damage. It lifted around 2:54 p.m.

A second EF2 tornado was confirmed in Olmsted County around 2:46 p.m. about 5 miles east-northeast of Viola and traveled about 7.5 miles, ending in Wabasha County, a few miles south of Plainview, around 3 p.m. Maximum wind speeds were around 125 mph. The storm affected mainly rural areas and damaged trees and outbuildings. One farmhouse lost a roof and a garage roof, the weather service said.

No injuries were reported in the Minnesota-Wisconsin outbreak.

Friday was a historic day for the NWS La Crosse office, which issued 26 tornado warnings – the most for any one day since the office opened in 1995.

Minneapolis city leaders say law enforcement, community members making Uptown safer, but more must be done

Minneapolis city leaders say law enforcement, community members making Uptown safer, but more must be done


Minneapolis Mayor Jacob Frey, Police Chief Brian O’Hara and other city leaders outlined ongoing efforts to improve safety and livability in the city’s Uptown neighborhood during a news conference Tuesday morning.

The discussion focused on a series of public safety initiatives, including expanded patrols by the Minneapolis Police Department and the planned growth of the city’s Community Safety Ambassador Program in Uptown.

That program is already in place elsewhere in south Minneapolis, on East Lake Street and Franklin Avenue. Officials said Tuesday it will come to Uptown in November. One dispatcher and up to eight ambassadors will be available to perform safety escorts, wellness checks, first aid and more.

Officials say efforts to increase safety in the area have been ongoing since December, when dedicated police patrols were introduced.

“Uptown is experiencing a comeback, but we need to be doing the work to make sure that it happens faster. We’ve all got these beautiful, nostalgic memories about what Uptown was six, seven, eight years ago. Twenty years ago,” Minneapolis Mayor Jacob Frey said. “What’s certain is the Uptown of the future is going to be dramatically different than the Uptown of the past.”

In March, dozens of people lined up for a community meeting discussing safety and livability concerns in the Uptown neighborhood. Data from the city shows there are more assaults, car thefts, robberies and calls for gunshots in the neighborhood compared to the same time last year. Community members, business owners and others have come together to launch community initiatives — like United Uptown — to get the area back on track.

Leaders describe the city’s approach as a coordinated strategy that combines public safety resources, infrastructure investments and partnerships with community organizations. City Council member Elizabeth Shaffer said the goal is “an Uptown that is safe, welcoming and enjoyable for everyone.”

Frey, O’Hara and Shaffer all highlighted drug use as a serious problem in the area. Shaffer and Frey said law enforcement has been helpful in curbing the issue, but more needs to be done. 

“We need to be stepping up to be honest about it, to do something about it, to provide the supports for people who need it and yes, also make sure that we’re enforcing the law,” Frey said. “That’s part of the comeback that we’re going to see in Uptown.”

The Minneapolis Police Department says that preliminary information indicates the driver, a 23-year-old man, had been traveling south on Hiawatha Avenue in a Ford Edge when he struck the bicyclist.

Officers arrested the driver and took him to the hospital, where police say “a search warrant for evidence collection was carried out.” Police later booked the driver into Hennepin County Jail on suspicion of criminal vehicular homicide.

The incident is still under investigation.
