UI researchers recommend improvements to private well testing program


Tyler Chalfant | August 20th, 2019

The University of Iowa Center for Health Effects of Environmental Contamination (CHEEC) released a report Monday outlining ways in which Iowa’s program to protect drinking water from private wells can be improved. According to the report, the state’s Grants to Counties program has been severely underutilized, with between 29-55% of the funds awarded to participating counties remaining unspent.

The program was created in 1987 as a part of the Groundwater Protection Act to provide funding for testing private wells for contamination, as well as reconstruction of private wells and plugging of abandoned wells. The US Environmental Protection Agency does not regulate private wells or recommend standards for individual wells, though it recommends testing wells annually for total coliform bacteria, nitrates, total dissolved solids, and pH levels. Nearly 300,000 Iowans rely on private wells as their primary source of drinking water.

CHEEC’s report, published in partnership with the UI Public Policy Center, recommends improving the Grants to Counties program by expanding the contaminants tested for, to include substances such as pesticides, manganese, lead, and copper. It also suggests prioritizing the most vulnerable wells and the counties with the greatest need, which have the greatest number of private wells and least access to Rural Water, and are already those that are most likely to better utilize the funding. Funding could also be used to assist with remedial actions, increase marketing for the program, and close gaps in the inventory to more accurately estimate the number of private wells in the state. 

Journalists and scientists talked environment at summit Tuesday

Urgent environmental challenges like climate change have made it increasingly vital for the public to know the facts. General audiences get information largely through news media, but distilling complicated science accurately is not always easy for writers. Friendly collaboration between scientists and journalists is crucial, for the sake of accuracy and public good.

An Environmental Journalism Summit in Grinnell, Iowa brought students and professionals in both fields together Tuesday to share thoughts on improving environmental science communication.

The University of Iowa’s Environmental Health Sciences Research Center organized the summit and presented on three “hot topics” in environmental news. Peter Thorne, head of the UI Department of Occupational and Environmental Health, spoke about his experiences advising the EPA under changing administration. Dr. Robert Blount discussed his medical research on air pollution and tuberculosis.  Darrin Thompson, associate director of the UI Center for Health Effects of Environmental Contamination (CHEEC), shared his knowledge and research on neonicotinoids, a controversial class of pesticides.

Two expert panels shared their knowledge and answered questions from moderators and audience members. The “Science and Media” panel featured Iowa Public Radio’s Amy Mayer, journalism professor Daniel Lathrop, Iowa Watch executive director Lyle Muller and engineer Craig Just, who discussed the complexities of communicating science. They stressed the importance of fact checking, including people in storytelling and maintaining responsibility to the audience.

Another panel focused on nitrates and water quality, featuring IIHR research engineer Chris Jones, CHEEC director David Cwiertny and Kajsa Dalrymple, who researches media effects on agricultural practices. They discussed gaps in coverage of the issue, the magnitude of the problem and the complex system that created it. 

Researchers also participated in more journalistic activities, like generating story ideas on hog manure. The summit ended with a showcase on Cedar Fall High School’s news team, which has published award-winning investigations on pesticide drift, climate  change education and drinking water nitrates through Iowa Watch.
