Webinar: An Invisible Threat: Nitrate in Drinking Water
In communities across the country, nitrate pollution is a tasteless, odorless, invisible contaminant posing serious harm to public health. Join Dr. David Cwiertny, Director of the University of Iowa’s Center for Health Effects of Environmental Contamination, for an in-depth exploration of how nitrate contamination in our water systems is a public health concern. This session will distill complex data into clear takeaways, highlighting the latest scientific links between nitrate exposure and adverse health outcomes including cancers, thyroid disease, birth defects, and more.
