Intro
I have been a hydrologist with the US Geological Survey for over 25 years, and have authored over 50 publications focusing on the source and transport of trace organics (including pharmaceuticals, hormones, personal care products and pesticides) in urban and agricultural settings across the United States. My research has focused on organic wastewater compounds in groundwater, surface water and wastewater systems. Most recently I have used newly developed analytical, sampling, and statistical techniques to assess loadings of hormones and other organic contaminants from combined sewer overflows to adjacent surface water systems.

Analysis of pharmaceutical and other organic wastewater compounds in filtered and unfiltered water samples by gas chromatography/mass spectrometry
Research on the effects of exposure of stream biota to complex mixtures of pharmaceuticals and other organic compounds associated with wastewater requires the development of additional analytical capabilities for these compounds in water samples. Two gas chromatography/mass spectrometry (GC/MS) analytical methods used at the U.S. Geological Survey National Water Quality Laboratory (NWQL) to analyzAuthorsSteven D. Zaugg, Patrick J. Phillips, Steven G. SmithMycotoxins: 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 were detected at least once during this study. The detAuthorsDana W. Kolpin, Judith Schenzel, Michael T. Meyer, Patrick J. Phillips, Laura E.

Organic contaminants and trace elements were measured in bed sediments collected from streams in seven metropolitan study areas across the United States to assess concentrations in relation to urbanization. Polycyclic aromatic hydrocarbons, polychlorinated biphenyls, organochlorine pesticides, the pyrethroid insecticide bifenthrin, and several trace elements were significantly related to urbanizatAuthorsLisa H.

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.

Facilities involved in the manufacture of pharmaceutical products are an under-investigated source of pharmaceuticals to the environment. Between 2004 and 2009, 35 to 38 effluent samples were collected from each of three wastewater treatment plants (WWTPs) in New York and analyzed for seven pharmaceuticals including opioids and muscle relaxants. Two WWTPs (NY2 and NY3) receive substantial flows (>AuthorsPatrick J. Phillips, Steven G. Smith, Dana W. Kolpin, Brooke W. Stinson, Steven D. Zaugg, Herbert T. Buxton, Edward T.

Abstract Wastewater-treatment-plant (WWTP) effluents are a demonstrated source of pharmaceuticals to the environment. During 2004-09, a study was conducted to identify pharmaceutical compounds in effluents from WWTPs (including two that receive substantial discharges from pharmaceutical formulation facilities), streamwater, and reservoirs. The methods used to determine and quantify concentrationsAuthorsPatrick J. Phillips, Steven G. Smith, Dana W. Kolpin, Steven D. Zaugg, Herbert T. Buxton, Edward T.

A primary pathway for emerging contaminants (pharmaceuticals, personal care products, steroids, and hormones) to enter aquatic ecosystems is effluent from sewage treatment plants (STP), and identifying technologies to minimize the amount of these contaminants released is important. Quantifying the flux of these contaminants through STPs is difficult. This study evaluates the behavior of gadoliniumAuthorsPhilip L. Verplanck, Edward T. Furlong, James L. Gray, Patrick J.

This project brought together a team of experts in the fields of environmental engineering, analytical chemistry and hydrogeology, and biological assay analysis to evaluate the occurrence and fate of estrogenic compounds and the estrogenicity of biosolids derived from wastewater treatment. The primary objective of the study was to provide key baseline information concerning the estrogenicity (measAuthorsEdward T. Furlong, James L. Gray, David M. Quanrud, S.E. Teske, K.J.

Abstract: Some sources of organic wastewater compounds (OWCs) to streams, lakes, and estuaries, including wastewater‐treatment‐plant effluent, have been well documented, but other sources, particularly wet‐weather discharges from combined‐sewer‐overflow (CSO) and urban runoff, may also be major sources of OWCs.

Across the United States, there is a rapidly growing awareness of the occurrence and the toxicological impacts of natural and synthetic trace compounds in the environment. These trace compounds, referred to as emerging contaminants (ECs), are reported to cause a range of negative impacts in the environment, such as adverse effects on biota in receiving streams and interference with the normal funcAuthorsPatrick J.

In addition to providing an understanding of processes within a catchment system, isotopic techniques have been instrumental in providing reconstructions of catchment climate and other environmental indicators at various time scales. Many recent changes are a direct consequence of anthropogenic activities. Isotopic analysis serves as a valuable tool for distinguishing between natural variations inAuthorsJames B.
