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.

Occurrence of selected pesticides and their metabolites in near-surface aquifers of the midwestern United States
The occurrence and distribution of selected pesticides and their metabolites were investigated through the collection of 837 water-quality samples from 303 wells across the Midwest. Results of this study showed that five of the six most frequently detected compounds were pesticide metabolites. Thus, it was common for a metabolite to be found more frequently in groundwater than its parent compound.AuthorsD.W. Kolpin, Thurman E. Michael, D. A. GoolsbyAcetochlor in the hydrologic system in the midwestern United States, 1994
The herbicide acetochlor [2-chloro-N-(ethoxymethyl)-N-(2-ethyl-6-methylphenyl)acetamide] was given conditional registration in the United States by the U.S. Environmental Protection Agency in March 1994. This registration provided a rare opportunity to investigate the occurrence of a pesticide during its first season of extensive use in the midwestern United States.

Atrazine and atrazine-residue (atrazine + two metabolites - deethylatrazine and deisopropylatrazine) concentrations were examined to determine if consideration of these atrazine metabolites substantially adds to our understanding of the distribution of this pesticide in groundwater of the midcontinental United States. The mean of atrazine.residue concentrations was 53 percent greater than that ofAuthorsS. Liu, S.T. Yen, D.W. KolpinUsing a geographic information system and scanning technology to create high-resolution land-use data sets
A geographic information system (GIS) procedure was developed to compile low-altitude aerial photography, digitized data, and land-use data from U.S. Department of Agriculture Consolidated Farm Service Agency (CFSA) offices into a high-resolution (approximately 5 meters) land-use GIS data set. The aerial photography consisted of 35-mm slides which were scanned into tagged information file format (AuthorsCraig A. Harvey, Dana W. Kolpin, William A.

The historic stream flooding and intense rainfall across the upper Mississippi River Basin during summer 1993 had an immediate effect on near-surface unconsolidated aquifers by raising the water levels closer to the land surface . The objective of this study was to determine if this flooding also had immediate effects on groundwater quality . Water samples were collected during September and OctobAuthorsDana W. Kolpin, E. Michael ThurmanA regional monitoring network to investigate the occurrence of agricultural chemicals in near-surface aquifers of the midcontinental USA
Previous state and national surveys conducted in the mid-continental USA have produced a wide range in results regarding the occurrence of agricultural chemicals in groundwater. At least some of these differences can be attributed to inconsistencies between the surveys, such as different analytical reporting limits. The US Geological Survey has designed a sampling network that is geographically aAuthorsD.W. Kolpin, D. A. GoolsbyPesticides in near-surface aquifers: An assessment using highly sensitive analytical methods and tritium
In 1992, the U.S. Geological Survey (USGS) determined the distribution of pesticides in near-surface aquifers of the midwestern USA to be much more widespread than originally determined during a 1991 USGS study. The frequency of pesticide detection increased from 28.4% during the 1991 study to 59.0% during the 1992 study. This increase in pesticide detection was primarily the result of a more sensAuthorsD.W.

The occurrence and distribution of selected herbicides, atrazine metabolites, and nitrate were determined for near-surface aquifers (within 50 feet of land surface) in the corn- and soybean-producing region of the midcontinental United States. The study region included all or parts of Illinois, Indiana, Iowa, Kansas, Michigan, Minnesota, Missouri, Nebraska, North Dakota, Ohio, South Dakota, and WiAuthorsDana W. Kolpin, Michael R.

Selected herbicides, atrazine (2-chloro-4-ethylamino-6-isopropylamino-s-triazine) metabolites, and NO−3 were examined in near-surface unconsolidated and bedrock aquifers in the midcontinental USA to study the hydrogeologic, spatial, and seasonal distribution of these contaminants.
