NASA is partnering with the University of Iowa, Cedar Rapids, Iowa City and Des Moines Water Works to create a new tool to forecast water quality conditions. The goal is to combine satellite imagery with water quality monitors across the state to predict when nitrate concentrations in surface or ground water will reach dangerous levels.

Water quality has become a bigger part of the public conversation in Iowa as the Des Moines metro and smaller communities around the state grapple with high nitrate levels. Many homeowners are concerned about their health and are looking into reverse osmosis to filter out these contaminants. -
A report from the Environmental Working Group claims thousands of feeding operations are off the DNR's radar. A representative with the Iowa Pork Producers Association says the DNR is following state law. Host Ben Kieffer speaks with the co-author of this report, Anne Schechinger, about how mapping animal operations relates to water quality issues, and Pork Association legal counsel Eldon McAfee shares what he thinks the report gets wrong. Then, Kieffer speaks with the recipient of the "Nobel Prize for statistics," University of Iowa professor emeritus Luke Tierney. -
Construction is underway on a new Innovation and Discovery Lab at Iowa Lakeside Laboratory that will expand hands-on learning for students of all ages. The new space will also support research to better understand and protect the water quality of the Iowa Great Lakes.

The Iowa DNR will move forward with demolishing an education center at Springbrook State Park after approval from the Natural Resource Commission. The center in Guthrie County made a big impact on thousands of students, educators and conservationists. -
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. -
Casey Lake is one of the latest to benefit from the state's Lake Restoration Program, which is marking 20 years of addressing water quality issues at recreation sites across Iowa.

The Iowa chapter of the Land Improvement Contractors of America says the space will make it easier to educate the next generation of professional contractors, along with government employees, lawmakers and students, to help conserve soil and water in the state through edge-of-field practices. They're a key part of Iowa's strategy to reduce nutrient pollution. -
Central Iowa Water Works — the regional water authority that serves one in five Iowans — has issued a lawn watering ban in the Des Moines area. It’s the result of a demand spike and consistently high nitrate levels in the rivers and other sources that provide water for the system. -
The Iowa Integrated Network for Science, Information, and Geospatial Health Tracking, or INSIGHT, will examine how factors like PFAS and nitrate affect Iowans' health
