Iowa’s water problem is not a mystery. High nitrate loads from agricultural runoff have pushed drinking water utilities like Des Moines Water Works into record stretches of nitrate removal. The state’s cancer rates rank among the highest in the nation and continue rising. Streams that once supported fishing and recreation now carry the signature of the corn-soy-CAFO system. Politicians have promised action for years. Results have been scarce.
This cycle offers something different: two candidates whose combined credentials match the scale of the problem. Republican gubernatorial nominee Zach Lahn brings a farmer’s understanding of what works on the ground and the political will to fund it. Democrat Chris Jones, running for Secretary of Agriculture, brings decades of hands-on scientific expertise measuring, documenting, and explaining exactly what is happening in Iowa’s water. Together, even if Jones serves only a single term, they have the tools to produce measurable improvement where previous administrations produced only reports.
Zach Lahn’s Practical Path
Lahn is a sixth-generation Iowan who bought back his family’s Belle Plaine farmstead after it left family hands. He has made water quality and cancer rates central to his campaign, explicitly linking elevated nitrates to colorectal cancer and other health outcomes. His approach prioritizes proven practices that reduce nutrient loss without bankrupting family farms.
He has called for finally funding the Iowa Natural Resources and Outdoor Recreation Trust Fund—the IWILL program voters approved by a 63 percent margin in 2010 but that lawmakers left empty. Lahn wants that money directed first at the most impaired watersheds: the Des Moines and Raccoon rivers and their tributaries. He points to saturated buffers, which Iowa State University research has shown can remove essentially all nitrate from tile drainage in tested settings. He favors incentives structured so farmers make money adopting deeper nitrogen application and other conservation measures rather than merely break even. Upstream and downstream monitoring would measure results. The goal is targeted progress that keeps land in Iowa hands instead of accelerating consolidation through heavy regulation.
Lahn’s record is that of a farmer and businessman focused on implementation. He has argued that the status quo—talking about water while avoiding hard choices on funding and incentives—has failed. His plan is not radical. It is the first serious attempt by a Republican nominee to treat the problem as both an environmental and public-health priority that can be addressed while supporting working farms.
Chris Jones’s Unmatched Expertise
Jones arrives with credentials no other statewide candidate possesses. He holds a Ph.D. in analytical chemistry. For eight years he managed the water quality testing laboratory at Des Moines Water Works, overseeing operations at one of the world’s largest nitrate-removal facilities built specifically for agricultural runoff. He then spent four years as an environmental scientist with the Iowa Soybean Association, helping deploy some of the state’s earliest independent monitoring systems. At the University of Iowa he worked as a research engineer and helped create the first real-time public sensor network tracking nitrate and other pollutants across Iowa’s rivers—the system that later faced funding cuts.
His 2023 book, The Swine Republic, was selected by the Library of Congress as Iowa’s representative at the National Book Festival. He co-founded Driftless Water Defenders to protect northeast Iowa’s waters. For decades Jones has measured the loads, traced the sources, and explained in plain language why the current production system produces the outcomes Iowans see in their faucets and in the Gulf dead zone. He knows the data because he generated much of it.
That body of work is the difference between someone who tours a treatment plant and says he is “listening and learning” and someone who has spent a career inside the problem.
The Combination That Can Deliver
Lahn as governor would set the priority, secure the funding through IWILL and other mechanisms, and structure incentives that farmers can actually accept. Jones as agriculture secretary would bring the institutional knowledge to design the interventions, expand and protect monitoring, and ensure resources go where the data show the biggest return. The two roles are complementary. The governor controls the budget and the bully pulpit. The agriculture secretary oversees conservation programs, technical assistance, and much of the interface with producers. One term of Jones in that office, paired with a Lahn administration that treats water as a top-tier issue, could establish the monitoring baselines, the practice adoption targets, and the accountability mechanisms that have been missing for a generation.
Critics will note the party difference. Lahn has emphasized voluntary incentives and avoided broad mandates that risk farm bankruptcies. Jones has been more direct about the need for systemic changes in the corn-soy-ethanol model. On the narrow but decisive question of cleaning Iowa’s water, however, their credentials align more closely than those of any other pairing on the ballot. Expertise plus political will is a rare combination. Iowa has the first and can elect the second.
The Credentials Gap with Rob Sand
Democratic gubernatorial nominee Rob Sand has released a water plan that includes more monitoring funding, a dirty-water notification system, expanded wetlands, and tax credits for conservation practices. Those are reasonable ideas. What Sand does not have is any professional background in water science, laboratory management, sensor networks, or published research on Iowa’s nutrient problem. His education is a political science degree and a law degree. His career is prosecution and state auditing. He has described his own process as still listening and learning by visiting treatment facilities.
That is not a criticism of Sand’s intentions. It is a statement of fact about the difference between a generalist politician and a specialist who has managed the largest nitrate-removal operation in the region, built the state’s real-time monitoring capacity, and written the most detailed public account of how Iowa’s agriculture produces its water outcomes. When the problem is technical, decades in the making, and tightly linked to the dominant industry, credentials matter. Sand has none of the specialized ones Jones has spent a career accumulating.
Iowans have heard promises before. This year they have a chance to elect a governor who has made water a defining issue and an agriculture secretary whose life’s work is the subject. Zach Lahn and Chris Jones, working from their respective offices, offer the most credible path yet to measurable improvement—even if Jones’s tenure is limited to a single term. The alternative is more of the same: plans without the people who actually know how to execute them.
