U.S. Geological Survey (USGS), Iowa City, Iowa, USA
Dr Dana Kolpin is a research hydrologist for the U.S. Geological Survey in Iowa City, IA. He received his B.S. from Iowa State University and his M.S. from the University of Iowa (both in geology). He has been the project chief of the USGS Toxic Program’s CECs in the Environment Project (http://toxics.ugs.gov/regional/emc/) since its inception in 1998. He has published over 150 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. More recently, he has published a diverse array of papers on the topic of CECs 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 to streams.
