Iowa water quality and cancer rates become key political issues

Iowa is facing a public health crisis characterized by high cancer rates and contaminated drinking water. The state currently ranks second in the nation for cancer incidence, with experts examining the links between agricultural pollutants—such as nitrates, pesticides, and PFAS—and human health.

Republican gubernatorial nominee Zach Lahn has made water quality a campaign priority, stating that discussions regarding cancer rates must include water issues. Lahn has committed to funding the Iowa’s Water and Land Legacy (IWILL) initiative, a clean-water program that currently lacks sufficient funding. He advocates for regenerative farming practices and incentives for conservation to reduce runoff without penalizing producers.

Public health experts and researchers are also calling for increased support for monitoring networks. Dr. David Cwiertny of the Iowa Institute of Hydraulic Research has emphasized the need to restore full funding to the state’s real-time nitrate monitoring network to better track and manage agricultural toxins in the water supply.
