Water quality once again took center stage during a legislative briefing in Fairfield.
Diane Rosenberg, executive director of Jefferson County Farmers and Neighbors, raised concerns about the future of Iowa’s water quality sensor network, which provides real-time nitrate monitoring. In a question submitted to lawmakers, Rosenberg asked whether the state would support restoring funding for the Iowa Institute of Hydraulic Research by allocating one million dollars annually from the Groundwater Protection Fund. Current funding for the program is set to expire July first.
Representative Helena Hayes acknowledged the funding is ending but noted that some local governments, including Polk County, have stepped in to help temporarily. She also encouraged residents to take individual steps to improve water quality, such as installing in-home filtration systems.
Senator Adrian Dickey pointed out that the Walton Foundation has taken on funding responsibilities and questioned whether the state should continue a program initially supported by a private entity. He added that the Iowa Department of Natural Resources already conducts extensive water testing and said the state currently spends about 46.5 million dollars annually on water quality efforts.
Representative Jeff Shipley expressed support for maintaining access to water quality data, emphasizing that government has a responsibility to provide that information. He also noted additional concerns, including pollution from microplastics.
Following the forum, Rosenberg noted that many of the current funding efforts are only temporary. She said counties like Polk and Johnson have agreed to help fund the sensors, but only for a limited time if state funding is not restored.
Rosenberg stressed that the sensors play a critical role for smaller municipal water systems by providing nitrate readings every 15 minutes, allowing communities to respond quickly if levels become unsafe.
She added that maintaining access to reliable water data is essential for public health and warned against losing both the investment and the protections the system provides.
