Dana W Kolpin
Biography
Dana received his B.S. from Iowa State University and his M.S. from the University of Iowa (both in geology). Dana started his career with the USGS in 1986. His research interests include the fate, transport, and effects of environmental contaminants (e.g. pesticides, human and veterinary pharmaceuticals, hormones, etc.) in the environment. He was the project lead of the USGS Toxic Program’s CECs in the Environment Project (https://toxics.usgs.gov/investigations/cec/) for its entire history (1998 – 2017). He 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: https://www2.usgs.gov/envirohealth/science_teams/food/index.php). 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.
