Dana W Kolpin
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. He most recent research interests include linking tap water quality to human health end points.
Science and Products
Mycotoxins: diffuse and point source contributions of natural contaminants of emerging concern to streams
To determine the prevalence of mycotoxins in streams, 116 water samples from 32 streams and three wastewater treatment plant effluents were collected in 2010 providing the broadest investigation on the spatial and temporal occurrence of mycotoxins in streams conducted in the United States to date. Out of the 33 target mycotoxins measured, nine...Kolpin, Dana W.; Schenzel, Judith; Meyer, Michael T.; Phillips, Patrick J.; Hubbard, Laura E.; Scott, Tia-Marie; Bucheli, Thomas D.
Dissipation of contaminants of emerging concern in biosolids applied to non-irrigated farmland in eastern Colorado
In 2007, a 1.5-year field-scale study was initiated by the U.S. Geological Survey to evaluate the dissipation of contaminants of emerging concern (CECs) following a first agronomic biosolids application to nonirrigated farmland. CECs with the greatest decrease in concentration in the surface biosolids at 180 days post-application included indole,...Yager, Tracy; Furlong, Edward T.; Kolpin, Dana W.; Kinney, Chad A.; Zaugg, Steven D.; Burkhardt, Mark R.
Bioassay of estrogenicity and chemical analyses of estrogens in streams across the United States associated with livestock operations
Animal manures, used as a nitrogen source for crop production, are often associated with negative impacts on nutrient levels in surface water. The concentrations of estrogens in streams from these manures also are of concern due to potential endocrine disruption in aquatic species. Streams associated with livestock operations were sampled by...Alvarez, David A.; Shappell, Nancy W.; Billey, L.O.; Bermudez, Dietrich S.; Wilson, Vickie S.; Kolpin, Dana W.; Perkins, Stephanie D.; Evans, Nicola; Foreman, William T.; Gray, James L.; Shipitalo, J.M.; Meyer, Michael T.
Chemical contaminants in water and sediment near fish nesting sites in the Potomac River basin: determining potential exposures to smallmouth bass (Micropterus dolomieu)
The Potomac River basin is an area where a high prevalence of abnormalities such as testicular oocytes (TO), skin lesions, and mortality has been observed in smallmouth bass (SMB, Micropterus dolomieu). Previous research documented a variety of chemicals in regional streams, implicating chemical exposure as one plausible explanation for these...Kolpin, Dana W.; Blazer, Vicki; Gray, James L.; Focazio, Michael J.; Young, John A.; Alvarez, David A.; Iwanowicz, Luke R.; Foreman, William T.; Furlong, Edward T.; Speiran, Gary K.; Zaugg, Steven D.; Hubbard, Laura E.; Meyer, Michael T.; Sandstrom, Mark W.; Barber, Larry B.
Managing the effects of endocrine disrupting chemicals in wastewater-impacted streams (Chapter 1)
A revolution in analytical instrumentation circa 1920 greatly improved the ability to characterize chemical substances. This analytical foundation resulted in an unprecedented explosion in the design and production of synthetic chemicals during and post-World War II. What is now often referred to as the 2nd Chemical Revolution has provided...Bradley, Paul M.; Kolpin, Dana W.

Persistence and potential effects of complex organic contaminant mixtures in wastewater-impacted streams
Natural and synthetic organic contaminants in municipal wastewater treatment plant (WWTP) effluents can cause ecosystem impacts, raising concerns about their persistence in receiving streams. In this study, Lagrangian sampling, in which the same approximate parcel of water is tracked as it moves downstream, was conducted at Boulder Creek, Colorado...Barber, Larry B.; Keefe, Steffanie H.; Brown, Greg K.; Furlong, Edward T.; Gray, James L.; Kolpin, Dana W.; Meyer, Michael T.; Sandstrom, Mark W.; Zaugg, Steven D.
Earthworm bioassays and seedling emergence for monitoring toxicity, aging and bioaccumulation of anthropogenic waste indicator compounds in biosolids-amended soil
Land application of biosolids (treated sewage sludge) can be an important route for introducing xenobiotic compounds into terrestrial environments. There is a paucity of available information on the effects of biosolids amendment on terrestrial organisms. In this study, the influence of biosolids and biosolids aging on earthworm (Eisenia fetida)...Kinney, Chad A.; Campbell, Bryan R.; Thompson, Regina; Furlong, Edward T.; Kolpin, Dana W.; Burkhardt, Mark R.; Zaugg, Steven D.; Werner, Stephen L.; Hay, Anthony G.
Combined sewer overflows: an environmental source of hormones and wastewater micropollutants
Data were collected at a wastewater treatment plant (WWTP) in Burlington, Vermont, USA, (serving 30,000 people) to assess the relative contribution of CSO (combined sewer overflow) bypass flows and treated wastewater effluent to the load of steroid hormones and other wastewater micropollutants (WMPs) from a WWTP to a lake. Flow-weighted composite...Phillips, P.J.; Chalmers, A.T.; Gray, J.L.; Kolpin, D.W.; Foreman, W.T.; Wall, G.R.
Occurrence of antibiotic resistance and characterization of resistant genes and integrons in Enterobacteriaceae isolated from integrated fish farms south China
Antibiotics are still widely applied in animal husbandry to prevent diseases and used as feed additives to promote animal growth. This could result in antibiotic resistance to bacteria and antibiotic residues in animals. In this paper, Enterobacteriaceae isolated from four integrated fish farms in Zhongshan, South China were tested for antibiotic...Su, Hao-Chang; Ying, Guang-Guo; Tao, Ran; Zhang, Rui-Quan; Fogarty, Lisa R.; Kolpin, Dana W.
On the need for a national (US) research program to elucidate the potential risks to human health and the environment posed by contaminants of emerging concernNovak, P.J.; Arnold, William A.; Blazer, V.S.; Halden, R.U.; Klaper, R.D.; Kolpin, D.W.; Kriebel, D.; Love, N.G.; Martinovic-Weigelt, D.; Patisaul, H.B.; Snyder, S.A.; vom Saal, F.

Nutrient and sediment concentrations and corresponding loads during the historic June 2008 flooding in eastern Iowa
A combination of above-normal precipitation during the winter and spring of 2007-2008 and extensive rainfall during June 2008 led to severe flooding in many parts of the midwestern United States. This resulted in transport of substantial amounts of nutrients and sediment from Iowa basins into the Mississippi River. Water samples were collected...Hubbard, L.; Kolpin, D.W.; Kalkhoff, S.J.; Robertson, Dale M.
