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.

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.

Flood Inundation Mapping Science

When planning for a flood, there are three key questions that must be answered: What areas will be flooded? How deep will the flood waters get? When will the flood arrive? Historical flooding can help a community anticipate how much impact similar flood events could have, but there are other methods and tools that can provide more accurate and nuanced estimations of a wide variety of flood...
