Study examines the potential adverse effects of fungicides on leaf decomposition by microbes and aquatic invertebrates.

Dr. Diann J. Prosser was awarded the Presidential Early Career Awards for Scientists and Engineers (PECASE).

U.S. Geological Survey (USGS) scientist Dr. Keith A. Loftin received the U.S. Environmental Protection Agency (EPA) Office of Water's Achievement in Science and Technology Award for his contributions to the National Wetlands Condition Assessment.

This visualization tool helps researchers and public health officials see how relations between poultry density and waterfowl migration routes affect the threat of avian influenza to people and the poultry industry.

Shifts in the overall microbial community structure were present in stream sediments that contained chemicals associated with unconventional oil and gas wastewaters. This work is part of a long-term study designed to understand persistence of chemicals from oil and gas wastewaters in sediments and water and how those factors might be related to exposures and adverse health effects, if any, on...

The addition of nitrate in a low oxygen groundwater resulted in the immobilization of naturally occurring dissolved arsenic and the conversion of nitrate to innocuous nitrogen gas.

A riparian zone rich in terrestrial insects can provide an alternate food source for fish in metal-impacted watersheds.

A new study measures the transport of chemicals associated with unconventional oil and gas (UOG) produced waters downstream from a pipeline leak in North Dakota. This work is part of a long-term study designed to understand chemical persistence in sediments and water and how those factors might be related to contaminant exposures and associated with adverse health effects, if any, on organisms.

The incidence of particular skin and liver tumors on white suckers collected from some Wisconsin rivers corresponded to the degree of urban development within the watershed. Further research is needed to understand the relationship between exposure to urban-sourced contaminants and the initiation, promotion, and potential for population-level effects of these tumors.

A new online interactive mapping tool provides summaries of decadal-scale changes in groundwater chemistry across the Nation.

Study finds bladder cancer risk was associated with water intake among participants with a history of private domestic well use. The trend was significant for participants who used shallow dug wells exclusively—a well type that typically has low arsenic concentrations but may have had higher concentrations historically.

First-ever reconnaissance study documents the off-field transport of nitrapyrin — a nitrification inhibitor applied with fertilizers as a bactericide to kill natural soil bacteria for the purpose of increasing crop yields — to adjacent streams. This study is the first step in understanding the transport, occurrence, and potential effects of nitrapyrin or similar compounds on nitrogen processing in...
