Iowa rivers face record nitrate levels following heavy rains
Recent heavy rains in Iowa have led to record nitrate levels in the state’s major rivers, prompting concerns over water safety and environmental impacts.
Jared Strong reports for Iowa Capital Dispatch.
In short:
- Record-high nitrate levels have been detected in the Boone, Cedar, Iowa, and Turkey rivers due to recent heavy rainfall.
- Des Moines Water Works has reactivated its nitrate removal system as nitrate concentrations in some rivers exceeded safe drinking water standards.
- State efforts to reduce river nitrate levels through voluntary conservation measures have shown little progress over the past decade.
Key quote:
“This is one of the biggest nitrate leaching events in 11 years.”
— David Cwiertny, director of the Center for Health Effects of Environmental Contamination at the University of Iowa
Why this matters:
High nitrate levels can lead to increased algae growth in rivers and lakes, reducing oxygen levels and harming aquatic life. These conditions can also pose a threat to public health, as they compromise the safety of drinking water sources, particularly in heavily impacted areas like Des Moines.

Groundbreaking held for Iowa Valley Habitat for Humanity’s 16th Woman Build
IOWA CITY, Iowa (KCRG) — Volunteers broke ground Saturday for Iowa Valley Habitat for Humanity’s 16th Woman Build, honoring a retired University of Iowa nursing professor.
Liz Swanson, a retired nursing professor, was chosen as this year’s honoree for her decades of impact. The Women Build program focuses on including women in every step of home construction.
While the home is built in Swanson’s honor, it will go to a fellow nurse and mother of three. The family applied through the affordable housing program.
Swanson said she’s proud to be part of a project that directly connects to her nursing legacy.
“It’s very special to have the unique opportunity to help the nurse who is working nights,” Swanson said.
Swanson said stable housing gives families the security to plan for the future.
“It means security for families. We talked briefly to the children and they said, ‘we’re gonna have our own bedroom,’” Swanson said.
Volunteers are set to begin work on the home in August. Those interested in volunteering can find more information here.
