Dana W Kolpin
Dana Kolpin is a Research Hydrologist, with the Central Midwest Water Science Center in Iowa City, Iowa. Dana started his career with the USGS in 1984. His research interests include the fate, transport, and effects of environmental contaminants (e.g. pesticides, human and veterinary pharmaceuticals, hormones, etc.) in the environment.
Dana was the project lead of the USGS Toxic Program’s CECs in the Environment Project for its entire history (1998 – 2017). He is now project lead of the USGS Toxic Program’s newly formed Food Project (i.e. understanding the potential for health risks from contaminant exposures associated with production, manufacturing, use, and consumption of food, beverage, and feedstock products). He has published over 200 papers and reports on environmental contaminants. His paper "Pharmaceuticals, hormones, and other organic wastewater contaminants in U.S. streams, 1999-2000: A national reconnaissance" was a seminal paper on the occurrence of CECs in water resources, and was the first national-scale study of such compounds conducted in the United States. This paper has become the most heavily cited paper in Environmental Science & Technology history. He has published a diverse array of papers on the topic of environmental contaminants including research on CECs in landfills, changes in stream water chemistry and hydrology related to the closure of a wastewater treatment plant, detection of swine hepatitis E virus in streams, the transport of neonicotinoid insecticides in streams, the uptake of CECs into earthworms and into fish neural tissue, the occurrence of natural toxins (i.e. phytoestrogens and mycotoxins) in streams, and the first ever documentation of the off-field transport on nitrapyrin and herbicide safeners to streams. His most recent research interests include linking tap water quality to human health end points, investigating PFAS exposures in rural settings, determining the prevalence of antibiotic resistance genes in the environment, and understanding chemical and microbial contaminants being discharged into the environment by food and feedstock processing plants.

From Stream to Spider: How PFAS Move Through Aquatic and Terrestrial Food Webs
Per- and polyfluoroalkyl substances (PFAS) are persistent synthetic chemicals that accumulate in the environment and living organisms. A USGS study examined how different PFAS compounds move through a stream ecosystem and are transferred from aquatic to terrestrial food webs. The findings documented that not all PFAS behave the same once they enter the environment, leading to differences in...
Bioenergy and Pesticides: Lessons from the AltEn Bioenergy Plant
Ethanol production from seed corn, while reducing waste and promoting renewable energy, can have environmental and health implications. A USGS study on a former bioenergy plant that received pesticide-coated seeds used for ethanol production, revealed that the process led to contaminated wastewater and solid residue, resulting in elevated pesticide levels in nearby surface waters even after the...
Helping Secure Our Nation’s Food Supply: The Intersection of Agriculture, Health, and Environment
Agriculture is vital to the U.S. economy, supplying food, fibers, fuels, and jobs. Ensuring the quality of our natural resources is essential for keeping our food safe and plentiful. The USGS studies environmental factors affecting food security and offers valuable insights to reduce health risks, ensuring a safer food supply and a healthier environment.
Beyond the Usual Suspects: A Comprehensive Look at Agricultural Stream Contaminants
Clean water is essential for both environmental health and human safety, but many everyday products and activities can contribute to water pollution including contaminants such as microplastics, harmful chemicals such as pharmaceuticals and pesticides, and antibiotic resistance genes. A recent USGS study in Iowa investigated pollutants in streams, including stream sediment and biota, to determine...
Wings of Change: The Environment's Influence on Bird Flu
Low pathogenic avian influenza (LPAI) viruses naturally occur in wild birds and are rarely fatal. Highly pathogenic avian influenza (HPAI) viruses are highly contagious, spread rapidly, are often fatal to poultry, and have been responsible for worldwide outbreaks. Together, LPAI and HPAI are generally referred to as either avian influenza viruses (AIVs) or "the bird flu."
Food Resources Lifecycle Integrated Science Team
The team studies the movement of toxicants and pathogens that could originate from the growing, raising, and processing/manufacturing of plant and animal products through the environment where exposure can occur. This information is used to understand if there are adverse effects upon exposure and to develop decision tools to protect health.
