Assessment of the immune status of wild and laboratory-maintained smallmouth bass

Deaths of young-of-year smallmouth bass in the Chesapeake Bay drainage has been noted since 2005. Studies of affected fish have found bacterial, viral and parasitic infections. Mixed infections suggest these fish are immunosuppressed. Understanding the role of specific pathogens and environmental factors that contribute to their presence is important but equally important is the understanding...

Water-Quality Trends

Is water quality getting better or worse?  Answering this deceptively simple question has been a fundamental objective of the USGS National Water-Quality Assessment Project’s research. Learn about trends in contaminants in the nation’s streams and rivers, trends in contaminants that collect in the bed sediment of streams and lakes, and changes in the quality of the nation’s groundwater.

Drinking Water Taste and Odor

Some water is just unpleasant to drink—it’s cloudy, or it smells or tastes bad. Some drinking water discolors teeth or skin, stains laundry or plumbing fixtures, or corrodes or clogs pipes. These effects are caused when some naturally occurring constituents occur at concentrations high enough to be a nuisance, and are particularly common where groundwater is used as a drinking water supply....

Sediment-Associated Contaminants

Stream, river, and lake bed sediment are reservoirs for many contaminants.  These contaminants include some “legacy” contaminants, like DDT, PCBs, and chlordane, and chemicals currently in use, like the insecticide bifenthrin and many flame retardants.  Learn about techniques used to study sediment-associated contaminants and their importance to aquatic biota.

Stream Ecology

Who lives in your stream? Rivers and streams, even small ones, are teeming with a vast number of species, including fish, aquatic invertebrates, and algae. Stream ecology is the study of those aquatic species, the way they interrelate, and their interactions with all aspects of these flowing water systems.

NWQP Research on Harmful Algal Blooms (HABs)

Harmful algal blooms (HABs) are caused by a complex set of physical, chemical, biological, hydrological, and meteorological conditions. Many unanswered questions remain about occurrence, environmental triggers for toxicity, and the ability to predict the timing, duration, and toxicity of HABs.

USGS / National Park Service Water-Quality Partnership

Since 1998, the USGS-National Park Service Water-Quality Partnership has supported 217 projects to protect and improve water quality in 119 national parks. These USGS-NPS collaborative projects support science-based resource management by the National Park Service to address critical water-quality issues for many of our Nation's most highly valued aquatic systems.

National Streamflow Information Program

The U.S. Geological Survey (USGS) operates and maintains a national streamgage network of about 8,000 streamgages (2018) to provide long-term, accurate, and unbiased streamflow information (often called discharge) to meet the multiple needs of many diverse users. Streamflow information is fundamental to national and local economic well-being, protection of life and property, and efficient and...
