Webinar: An Invisible Threat: Nitrate in Drinking Water
2026-07-29 13:00 - 14:00 (America/New_York) | Virtual, Virtual
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.

Webinar: Nitrate Pollution and the Dead Zone: Insights from the Gulf
2026-07-31 13:00 - 14:00
Each summer, the Gulf of Mexico develops a hypoxic “dead zone,” an area of low to no oxygen spanning thousands of square miles where aquatic life is scarce. Join Dr. Cassandra Glaspie of Louisiana State University for an exploration of the Gulf dead zone and its connection to nitrate pollution within the Mississippi River Basin. Drawing on her firsthand experience leading hypoxia cruises, Dr. Glaspie will share insights into the data collection process and what long-term nutrient dynamics reveal about the health of our coastal waters.
