Water

The Iowa Water and Land Legacy (IWiLL) Constitutional Amendment passed in 2010 with 63% of the vote. It was designed to fund a Natural Resources and Outdoor Recreation trust fund, but 16 years later, the trust has never been funded. A new effort to fund the trust is underway. On this episode, we hear from Adam Shirley, CEO of Iowa’s County Conservation System, Anna Gray of the Iowa Natural Heritage Foundation, and Lindsay Brice of Audubon Upper Mississippi River. We talk about the strain of stagnant or dwindling funding on county conservation boards and what IWiLL could mean for those programs. Then, we listen back to a conversation about some of the oldest book clubs in Iowa from their members. (Part of this show was originally produced March 31, 2026.)

A report from the Iowa DNR shows Iowa had 36 nitrate-related drinking water violations in 2025, which is more than double the number reported in 2024.

Iowa's farmland sits on more than soil — deep underground may be the makings of a clean energy economy. On this episode, we go beneath Iowa's surface to talk about a billion-year-old rock formation where geologic hydrogen is hiding. We talk with Ryan Clark, associate state geologist at the Iowa Geological Survey and Betsy Swanner, an Iowa State University professor of Earth, atmosphere and climate to find out what it would take to actually build a hydrogen economy in Iowa. Then, Iowa State University agronomist Jianming Yu shares what artificial intelligence and citizen science reveal about how plants adapt to their environments.

The issue of data centers is heating up in a small community just south of Sioux City. Residents say they were left in the dark, and Woodbury County officials are considering new regulations.

Data centers are massive and thirsty for water and power. Iowans are split on whether they're good neighbors. On this episode, the data center debate as cities and counties throughout the state are weighing potential data center installations. First, a Brookings Institution researcher on what rural communities stand to gain and lose from these developments. Then, Linn County Supervisor Sami Scheetz joins to discuss the ordinance they passed earlier this year and how it compares to other local governments' approaches to recent data center proposals. Iowa’s state geologist discusses whether Iowa's groundwater supply can handle the demand from data centers. And a public health researcher joins to discuss the public health implications from data centers powered by nonrenewable sources.

At the first reading of a proposed data zoning ordinance, residents of Palo and nearby communities raised concerns over the negative impacts future data centers could have on water and traffic, as well as light and noise pollution. Many people asked for the city to tighten regulations, while several others asked the city to table the ordinance completely.
