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 dichloroacetamide herbicide safeners and co-applied herbicides in midwestern U.S. streams
Dichloroacetamide safeners (e.g., AD-67, benoxacor, dichlormid, and furilazole) are co-applied with chloroacetanilide herbicides to protect crops from herbicide toxicity. While such safeners have been used since the early 1970s, there are minimal data about safener usage, occurrence in streams, or potential ecological effects. This study focused on one of these research gaps, occurrence in streamsAuthorsEmily Woodward, Michelle L. Hladik, Dana W. KolpinEstimating virus occurrence using Bayesian modeling in multiple drinking water systems of the United States
Drinking water treatment plants rely on purification of contaminated source waters to provide communities with potable water. One group of possible contaminants are enteric viruses. Measurement of viral quantities in environmental water systems are often performed using polymerase chain reaction (PCR) or quantitative PCR (qPCR). However, true values may be underestimated due to challenges involvedAuthorsEunice A. Varughese, Nichole E Brinkman, Emily M Anneken, Jennifer S Cashdollar, G. Shay Fout, Edward T. Furlong, Dana W. Kolpin, Susan T. Glassmeyer, Scott P KeelyInvestigating the influence of nitrate nitrogen on post-smolt Atlantic salmon Salmo salar reproductive physiology in water recirculation aquaculture systems
A major issue affecting land-based, closed containment Atlantic salmon Salmo salar growout production in water recirculation aquaculture systems (RAS) is precocious male maturation, which can negatively impact factors such as feed conversion, fillet yield, and product quality. Along with other water quality parameters, elevated nitrate nitrogen (NO3-N) has been shown to influence the reproductiveAuthorsChristopher Good, John Davidson, Luke R. Iwanowicz, Michael T.

The increasing use of pharmaceuticals has led to their subsequent input into and release from wastewater treatment plants, with corresponding discharge into surface waters that may subsequently exert adverse effects upon aquatic organisms.

Prioritization methodologies are often used for identifying those pharmaceuticals that pose the greatest risk to the natural environment and to focus laboratory testing or environmental monitoring toward pharmaceuticals of greatest concern. Risk-based prioritization approaches, employing models to derive exposure concentrations, are commonly used, but the reliability of these models is unclear. ThAuthorsEmily E.

The highly pathogenic avian influenza (H5N2) outbreak in the Midwestern United States (US) in 2015 was historic due to the number of birds and poultry operations impacted and the corresponding economic loss to the poultry industry and was the largest animal health emergency in US history.

During the 2015 outbreak of highly pathogenic avian influenza virus (HPAI) on poultry farms in the midwestern United States, concern was raised about the potential for HPAI to contaminate groundwater. Our study objective was to evaluate the occurrence of HPAI in the groundwater supply wells on 13 outbreak-affected poultry farms in Iowa and Wisconsin.

Surface water from 38 streams nationwide was assessed using 14 target-organic methods (719 compounds). Designed-bioactive anthropogenic contaminants (biocides, pharmaceuticals) comprised 57% of 406 organics detected at least once. The 10 most-frequently detected anthropogenic-organics included eight pesticides (desulfinylfipronil, AMPA, chlorpyrifos, dieldrin, metolachlor, atrazine, CIAT, glyphosaAuthorsPaul M.

Neonicotinoid insecticides are widespread in surface waters across the agriculturally-intensive Midwestern US. We report for the first time the presence of three neonicotinoids in finished drinking water and demonstrate their general persistence during conventional water treatment.

Neonicotinoids are a widely used class of insecticides that are commonly applied as seed coatings for agricultural crops. Such neonicotinoid use may pose a risk to non-target insects, including pollinators and natural enemies of crop pests, and ecosystems. This study assessed neonicotinoid residues in groundwater, surface runoff water, soil, and native plants adjacent to corn and soybean crop fielAuthorsMichelle L. Hladik, Steven Bradbury, Lisa A.

Five parabens used as preservatives in pharmaceuticals and personal care products (PPCPs) were measured in sewage sludges collected at 14 U.S. wastewater treatment plants (WWTPs) located in nine states. Detected concentration ranges (ng/g, dry weight) and frequencies were as follows: methyl paraben (15.9 to 203.0; 100%), propyl paraben (0.5 to 7.7; 100%), ethyl paraben (< 0.6 to 2.6; 63%), butyl pAuthorsJing Chen, Benny F.

A vast array of chemical compounds are in wide commercial use in the United States, and the potential ecological and human-health effect of exposure to chemical mixtures has been identified as a high priority in environment health science.
