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.

John Byrnes of the USGS office in Troy, NY collecting a Hurricane Irene sample at the Mohawk River at Cohoes on August 29, 2010. As Hurricane Irene left her mark along the East Coast, USGS crews sampled water for pesticides, E. coli, nutrients, and sediment to document water quality in areas affected by the hurricane.

USGS scientists processing samples of combined sewer overflow water collected after a storm. The samples were analyzed for selected wastewater-related chemicals.

Environmental and anthropogenic drivers of contaminants in agricultural watersheds with implications for land management
Groundwater discharges as a source of phytoestrogens and other agriculturally derived contaminants to streams
Pesticides and their degradates in groundwater reflect past use and current management strategies, Long Island, New York, USA
Pharmaceutical manufacturing facility discharges can substantially increase the pharmaceutical load to U.S. wastewaters
The impact of onsite wastewater disposal systems on groundwater in areas inundated by Hurricane Sandy in New York and New Jersey
