Understanding the Pesticide Problem in Montana’s Waterways – Flathead Beacon
Are pesticides a problem in Montana’s waters? How many of these chemicals, which include insecticides, herbicides, fungicides and more, commonly used on lawns and farms alike, have made their way into our waterways? How can we still control pests and keep our waters clean for future generations? The Pesticide Stewardship Partnership Program (PSPP) is an ambitious initiative led by assistant research professor Dr. Rachel Malison at University of Montana, Flathead Lake Biological Station (FLBS) and is funded by a U.S. Environmental Protection Agency grant. The PSPP is working to answer these questions in western Montana — the headwaters of the Columbia River Basin. To chart a course for sustainable pest management in Montana’s future, Malison said, the program aims to build a network of partners, collect data to detect if pesticides are in Montana waterways, and to provide education on sustainable pesticide practices and alternatives, and more.
This story starts in the field. Big Sky Watershed Corps member Chloe Czachor, who is serving her term at FLBS with PSPP, carefully pulls her weathered FLBS expedition off a gravel road near Ronan, Montana. The nearby irrigation ditch will be her fifth sampling stop of the day, another step in her largely solitary journey to collect samples from western Montana waterways that will be used to test for the presence of pesticides. In its first year of sampling, the PSPP is aiming to collect around 650 samples from rivers, streams and other waters in Montana’s portion of the Columbia River Basin. Most of these waterways have never been sampled for pesticides before, Czachor said, and whether they are contaminated with pesticides is unknown.
Czachor unloads her gear from the back of the vehicle, including an instrument that measures water characteristics like temperature and pH, a large glass bottle and water-resistant notebooks, and carries the gear over to the ditch which eventually flows back into the river. The instrument’s probe goes in the water to start measuring while Czachor wades into the stream and fills the bottle with water. After writing in the site name and location, Czachor enters the instrument’s readings into the notebook before pulling it out of the water. Then, she hauls her gear back to the vehicle, finds the next stop on Google Maps and starts driving again.
Later, at the PSPP team’s base at the FLBS, Czachor unloads the coolers filled with water sample bottles from her latest sampling run. These samples will join hundreds of others that the PSPP has gathered so far from across western Montana. Samples are delivered once a week to the Montana Department of Agriculture Analytical Laboratory in Bozeman, which analyzes each sample for 103 pesticide compounds. This is only a fraction of the number of different pesticides used in Montana, Czachor said, but detecting the presence of these chemicals can also indicate that other chemicals might also be present.
Czachor’s sample collecting work started in April. As the team’s main sample collector, she said that she has driven all over western Montana while sampling. Staff from FLBS and other volunteers are able to help Chloe sample part of the time, but she is leading the effort.
The travel takes a physical toll, Czachor said. “It’s long hours and I definitely need to be doing more yoga after how wrecked my body feels after being that long in the car. … These cars are so old, there’s no sort of lumbar support in the seats.” However, she said that she doesn’t mind when she is alone for so long on sampling runs. “I’m an introvert at heart,” she said. “I have my music and I have my podcasts and my audiobooks.” Sometimes, Czachor said that she calls friends while on long sampling drives. On the longest days, she said she focuses on the value of the experience for her career in conservation and on the unique opportunity of helping build a large-scale pesticide monitoring program where none existed before. “I’ve seen some pretty incredible places through this work, places that I would have never known existed. As someone new to Montana, I can’t think of a better way to see so much of the state. And to be seeing these beautiful places and know that I’m helping to protect them in some way is very rewarding,” Czachor said.
Czachor’s travels are guided by Research Coordinator Janelle Groff and Research Scientist Diane Whited. Together, they developed the maps of pesticide sampling sites the program uses and create the routes that Czachor and others travel each week on sampling trips. Whited used a variety of geospatial data to create maps of how likely waterways are to be contaminated with pesticides, based on different land uses and their proximity to surface water. Using these risk maps, the team then randomly created a roster of potential sampling locations on waterways with varying risks of pesticide contamination and near a range of land uses, from agriculture to residential areas to National Forests.
The sampling effort is divided into different types of sites, Groff said. Even though the program will collect many samples, the large area and variety of land uses the program aims to monitor mean that a limited number of samples can be collected at each site. However, pesticide concentrations can change over time as different pests emerge on nearby lawns and farms, stream flows rise and fall, and other seasonal changes shifts occur. PSPP monitors a broad area while also tracking changes in pesticide concentrations over time by dividing monitoring into three types of sites, Groff said. At a small set of focal sites, samples are collected every two weeks or once a month to detect potential changes over time. The larger set of baseline sites are only visited once or twice a year but span a much broader area. Focal and baseline sites are located on waterways at high risk of pesticide contamination. Together, these sites allow the program to monitor a large geographic area and understand changes over time, Groff said. In addition to testing focal and baseline sites, she said the program also tests reference sites, which are located in areas with low chances of pesticide contamination, like stream locations in National Forest or near remote headwaters. The results from these samples, which should show very low levels of pesticides, help substantiate that the testing regimen is accurate and provide data on baseline pesticide levels in the environment, Groff said.
Using this roster of potential sampling sites, Groff builds routes for Czachor to follow on her weekly trips. She said that building these routes involves Google Maps and “a lot of zooming” since she must ensure that Czachor can safely park her vehicle near each site and can physically reach the water. Groff also provides a list of alternative sites for each of Czachor’s trips, in case a site is inaccessible or the stream or ditch is dry when she reaches it.
The sampling effort just launched in the spring of 2025, Groff said, and extensive data will likely not be available for some time. In the future though, she said that this data will help Montana residents understand and address pesticide contamination in their waters by identifying where it is occurring and what pesticides are involved. The fate and transport of pesticides from land to water is very complex because there are so many pesticides and they have different characteristics, which means that some reach water more easily than others. The data collected will help individuals understand the water conditions around them and guide larger scale collective efforts to reduce the amounts of pesticides in the water, Groff said. She also said that knowing where pesticides are common in the water will help guide education about pesticide use, another key part of PSPP’s mission.
On a rainy and cold day on Flathead Lake, Rachel Malison stands by the rail of the boat and speaks to the small crowd about the PSPP program and the importance of using good stewardship practices to control pests. Malison is speaking at the annual FLBS Research Cruise, where people from neighboring communities can learn about research at the station and see demonstrations while cruising Flathead Lake on the chartered boat. Malison explains to the group that the available tools for controlling pests are like a Swiss Army knife, and that people tend to pull out the pesticides first to tackle a pest problem, like they pull out the knife first even though another tool might be just as or more effective. She says that sustainable pest management requires using all the tools available in a careful and judicious manner, including proper use of pesticides, to keep pests controlled and waters clean.
Opportunities like this are part of the PSPP’s broader educational project, Malison said. PSPP uses both direct outreach, like speaking at the Research Cruise or giving presentations to homeowner’s associations, and indirect outreach through partners like the Montana Watershed Coordination Council to spread information about proper pesticide use and best stewardship practices, she said. The education work also covers important water science concepts, like the idea that water moves pollutants, including how large rain events or excessive lawn watering can move chemicals on the land into the groundwater or nearby streams. “For a lot of the outreach and education, we’ve been realizing that we need to start by sharing more about how water moves and how our actions influence what is carried with that water when it’s moving” she said. This education is “trying to help people know that there are more options to pest management and that their actions can make a difference,” Malison said.
“That part of the program is going to grow and continue to get bigger as the program progresses,” Malison said, with PSPP being only in its second year. She said that the program is developing more outreach materials and going to more events, like the Northwestern Agricultural Research Center Field Day or the Bigfork Monday Market. The pesticide sampling work will help guide this outreach, she said, letting the team identify areas with particularly high levels of pesticides and target outreach to the have the maximum impact. “If we find pesticides in waters near different land uses, we can share that information with people and also provide ideas on how land uses could be modified to help protect our waters,” Malison said.
These outreach efforts have already had impacts, said Malison, such as one homeowner’s association that it now considering a buffer strip between its lawns and nearby ponds to reduce the movement of pesticides into the water after hearing a talk from her. Although reaching everyone or making large changes to pesticides use may be difficult, Malison said that even small changes, like spraying lawns twice a year instead of four times, can reduce the amount of chemicals that enter the water.
For Malison, this work has personal meaning. “We live here, I have children, I want their children to have healthy rivers and functioning ecosystems too. We produce chemicals and we use them, it’s not just going away, so we need to make the best decisions we can to protect our waters.”

Brian Miller won the Democratic primary Tuesday for the U.S. House seat in Montana’s eastern district.
The Associated Press called the race for Miller, an attorney in Helena, who fended off a challenge from state Sen. Jonathan Windy Boy, a longtime legislator from Box Elder, and Sam Lux, a farrier from Great Falls.
In the Republican and rural eastern district, any Democrat will be an underdog, and Miller will face off against incumbent Republican U.S. Rep. Troy Downing, who was unopposed Tuesday.
Libertarian Patrick McCracken is also running.
In the primary, Miller took 58% of the vote. Lux took 27% and Windy Boy took 16%, according to the Montana Secretary of State’s website.
In April, Windy Boy paused his campaign amid “serious sexual abuse” allegations raised by the Montana Democratic Party — but Windy Boy restarted his campaign and later called the allegations “political attacks.”
Miller is representing the victim of the alleged abuse and her mother, although he said he didn’t take on the role until after Windy Boy initially suspended his campaign.
The Western Montana Food and Farm Trail, a new agritourism initiative led by Farm Connect Montana, launches May 30, offering locals and visitors a new kind of food and farm adventure across Western Montana.
Running June 1 through October 31, the self-guided Trail spans more than 200 miles and features more than 100 farms, ranches, farmers markets, restaurants, breweries and food businesses across the Missoula, Bitterroot, Flathead and Mission Valleys. Along the way, participants are invited to meet growers and makers, taste what’s in season and experience the culture and care behind Western Montana’s local food community.
At the center of the experience is the passport-style Trail Field Guide, illustrated by Missoula-based artist Courtney Blazon. The guide features illustrated maps, curated itineraries, seasonal highlights and more than 100 local food destinations throughout the region. The guide also includes more than $130 in special offers from participating farms and businesses.
Participants can collect stamps at Trail stops along the way to qualify for prizes, giveaways, or simply as a way to document their journey. End-of-season prizes include raffles for three CSA memberships valued at over $600 each, as well as local food and farm gift certificates, product bundles and Courtney Blazon-designed market totes.
The Trail is a regional collaboration led by Farm Connect Montana in partnership with Land to Hand Montana, The O’Hara Commons and Sustainability Center and Abundant Montana, organizations working to strengthen local food systems across Western Montana. The project aims to support local farms and food businesses through expanded visibility and agritourism opportunities while reconnecting locals and visitors with the people, places and stories behind their food.
“In creating the Western Montana Food & Farm Trail, we hope to inspire both residents and travelers to discover the stories behind their food and connect with the people cultivating a more vibrant, resilient and locally rooted food community,” said Bonnie Buckingham, Executive Director of Farm Connect Montana. “Participation in the Trail is a win for everyone. It creates new opportunities for farms and local food businesses to reach wider audiences while encouraging participants to explore new places, support local producers and experience Western Montana in a more meaningful way.”
“Land to Hand is thrilled to partner with Farm Connect on the Food and Farm Trail to highlight the robust agricultural heritage of Western Montana,” said Gretchen Boyer, Executive Director of Land to Hand Montana. “This initiative is more than just a guide – it’s an invitation to celebrate and support the local farmers who nourish our communities every day. By connecting residents and visitors directly to the source, we’re strengthening our local food system and honoring the people and landscapes that sustain the Flathead Valley.”
To celebrate the launch, regional Trail launch parties will take place in Missoula, the Bitterroot Valley and the Flathead Valley throughout early June, featuring Field Guide distribution, local food vendors, giveaways and opportunities to learn more about the Trail.
Trail Field Guides ($10) will be available for purchase beginning May 30 both online and at participating businesses, farmers markets and community locations throughout the region. A full list of Field Guide purchase locations and details, as well as a digital map and Trail listings, special events and more information is available at farmconnectmontana.org/trail.
Funding for this project was made possible through the U.S. Department of Agriculture’s Agricultural Marketing Service.

Six states — California, Iowa, Montana, New Jersey, South Dakota and New Mexico — hold elections on Tuesday. Most of the attention is on California and Iowa, where there are competitive primaries for governor. In both states, the Democratic Party also sees a road map to control of Congress in the fall.
In California’s unique primary system, voters send the top two vote-getters to November’s general election, regardless of candidates’ political parties. Democratic Gov. Gavin Newsom is term limited, and California voters will also pick who should move on to the general election in five new Democratic-leaning congressional districts.
In Iowa, Democratic voters will choose a candidate in a key Senate race — the Republican in the race is already the de facto nominee. In order to win a majority in the Senate, Democrats must pick up four seats, forcing the party to win in Republican-leaning states like Iowa. For governor, the race is the first good chance Democrats have to win the office in years, but Republicans still need to select their nominee.
Here are key races to follow:
Or skip to specific races:
California governor | California U.S. House | Iowa governor | Iowa U.S. Senate | New Jersey and Montana

California decides top two gubernatorial contenders
It’s been a chaotic scramble to pick the next leader of the country’s largest state. After three prominent Democrats — former Vice President Kamala Harris, Sen. Alex Padilla and state Attorney General Rob Bonta — decided not to run, Democratic voters haven’t had a clear front-runner for the first time in decades. Voters have more than 60 candidates to choose from, but only a fraction of those are considered serious contenders. Only the top two vote-getters will move on to the general election in November.

The race got a shakeup when former Democratic Rep. Eric Swalwell, the presumed favorite, dropped out of the race after he was accused of sexual misconduct by several women. Most recently, polls show the contest could be between two Democrats — the Health and Human Services secretary under former President Joe Biden, Xavier Becerra, and billionaire philanthropist Tom Steyer.
Before Becerra was appointed to Biden’s Cabinet, he served 12 terms in Congress and was elected as the California attorney general in 2016. He’s considered by many as the candidate with the strongest political background. Becerra’s pitch is that he is a proven leader who can hold his own and protect California from President Trump.
Steyer has forked over more than $213 million of his own fortune on the race and is also financially backed by Our Revolution, a group aligned with Sen. Bernie Sanders, I-Vt. Steyer’s platform is centered on taking a stand against special-interest groups in politics.
Polling just a few points behind Becerra and Steyer is Republican Steve Hilton. The former Fox News host was endorsed by President Trump in April, after which Riverside County Sheriff Chad Bianco, another Republican in the race, quickly dropped in the polls. Hilton’s platform focuses on increasing affordable housing supply for first-time homebuyers, bolstering tech industries and reviving California’s film industry.

The outcome of California’s new congressional districts
In response to Texas redrawing its congressional lines to create five Republican-leaning districts at the behest of President Trump, Californians approved Proposition 50 in November last year. The measure temporarily sidestepped the independent redistricting commission tasked with drawing nonpartisan influenced congressional boundaries, in favor of politically gerrymandered districts. That allowed state Democrats to redraw their map so five previously Republican-held districts now lean Democratic.
This has left those Republican incumbents figuring out their political futures. Rep. Ken Calvert, the longest-serving Republican from California, and Rep. Young Kim are running in the same district, for example, in a race that’s gotten quite heated.
Then there’s Rep. Kevin Kiley. After being drawn into a much more Democratic-leaning district, he decided to run in a new seat and announced he was leaving the Republican Party and running as an independent instead, though Kiley said would still caucus with the Republicans.
Because of California’s primary system, some of these more competitive seats are creating competitive primaries between Democrats, allowing primary voters to signal to the party what kinds of candidates speak to them most in places that have the most to lose — and gain.
Iowa’s GOP gubernatorial primary
Iowa Republican voters could decide the party’s nominee for governor in the state’s first open race for the office since 2011, as sitting Gov. Kim Reynolds opted not to run for reelection.
With five Republicans on Tuesday’s ballot, Rep. Randy Feenstra is the only one endorsed by Trump. The race will test whether Trump’s endorsement holds weight in a state where his approval rating has slipped over the economy and the war in Iran. Feenstra’s lead may be declining, as one recent poll shows political newcomer and Iowa businessman Zach Lahn could have a shot at winning the GOP primary.
There is a good chance, though, that Iowans won’t know the outcome of the race on Tuesday because a candidate must secure 35% of the vote to win outright. If no one clears that threshold, the nominee will be decided at a Republican convention where delegates — not primary voters — make the final choice.
But the Republican-backed candidate isn’t a shoo-in come November. Cook Political Report categorizes the governor’s race as a toss-up with a slight Republican advantage. Whatever Republican wins on Tuesday will face unopposed Democratic State Auditor Rob Sand in the general election. Sand is popular among voters and has, so far, outraised any other candidate for governor.
Democrats look to flip Iowa Senate seat
Democratic voters in Iowa will pick which candidate they think has the best shot at beating the Republican nominee for Senate, expected to be Trump-endorsed Rep. Ashley Hinson, on Tuesday. This is a seat that Democrats believe they have a shot at flipping come November. It’s part of a larger strategy of expanding their map — and winning in states currently held by Republican senators — if they want a chance to retake the Senate majority.
Iowa Democrats have a choice between state Rep. Josh Turek and state Sen. Zach Wahls. Both candidates are courting different Iowa voters, though. Turek is vying for the independent-leaning vote, while Wahls is hoping to gain the support from committed Democrats. Turek flipped a state House district held by a Republican, while Wahls represents a Senate district that is solidly blue. Both argue they are the candidate who has the right message to win in November.
And with three competitive congressional races on the ballot, some Democrats in the state are feeling like the road to a Democratic majority in Congress runs through Iowa.
Looking beyond Tuesday
New Jersey and Montana also have competitive races that could decide which party has control of Congress.
In New Jersey, all eyes are on Congressional District 7. Four Democrats are hoping to oust Republican Rep. Thomas Kean Jr. The sitting congressman has been notably absent from Washington for weeks due to what Kean cites as unspecified medical issues. He has missed more than 100 House votes since his last recorded vote on March 5.
Two races in Montana may be more competitive than originally expected with the last-minute announcements — shortly before the filing deadline — by Republicans, Sen. Steve Daines and Rep. Ryan Zinke, that neither would seek reelection.
While an open Senate seat does not make Montana, which has long been considered a Republican stronghold, necessarily competitive for Democrats, an independent candidate is outraising candidates in both major parties. Seth Bodnar, Iraq war veteran and former president of the University of Montana, is hoping voters will send him instead, mostly on the message that he won’t work for either party and is focused on changing the direction America is heading. In Bodnar’s case, he has enough voter signatures to land himself on the November ballot, but the Montana Secretary of State’s Office hasn’t yet certified those signatures.
Democrats are working to flip Montana’s 1st Congressional District as well. When Zinke announced he was retiring from Congress, it was seen as an opening for Democrats to compete. Now, four Democrats are angling for the open seat, including front-runner Sam Forstag, a smokejumper who is endorsed by popular progressive Rep. Alexandria Ocasio-Cortez, D-N.Y.
