USGS fills a knowledge gap for radionuclide occurrence in groundwater

Using recently developed and sensitive laboratory methods, the USGS has documented where the radionuclides lead-210 and polonium-210 occur in principal aquifers of the U.S. used for drinking-water supply, reports a ...

The USGS is Ready to Respond During the 2020 Atlantic Hurricane Season

The 2020 Atlantic hurricane season starts June 1, and the U.S. Geological Survey is prepared to provide science that can help guide efforts to protect lives and property if a major storm makes landfall this season.

USGS Crews Measure Major Flooding in Lower Michigan

U.S. Geological Survey field crews are measuring record flooding on the Tittabawassee River in Midland, Michigan, following a heavy rainfall event.

A comprehensive assessment of fluoride in groundwater

Fluoride occurs commonly in groundwater used for drinking, but typically at concentrations less than the drinking-water standard for human health, reports a new study by the U.S. Geological Survey. In fact, fluoride concentrations in most drinking-water wells sampled were below the optimal concentration recommended to prevent tooth...

USGS Responds to Spring Flooding

U.S. Geological Survey field crews are measuring flooding across the country as spring weather is in full swing. Warming temperatures, increased precipitation and snowmelt have caused moderate to major flooding in the upper Midwest, East Coast, Central Plains and the Southeast portions of the country.

Modification of Streamflow Across the U.S.

Human activities have caused flows in many of the Nation’s streams and rivers to be different from what they would be naturally. A new USGS study reports that, at a national scale, human management of land and water resources have modified natural patterns of streamflow along an estimated 1.2 million stream miles—more than one-third—of...

A slimy source of information on pesticides in streams

Analysis of stream biofilms reveals the presence of a wider array of pesticides than analysis of bed sediment, reports a new study by the U.S. Geological Survey Regional Stream Quality Assessment. Biofilm analysis may also be a better predictor of potential adverse effects on the community...

Naturally Occurring Contaminants in "Ancient" Groundwater of the Atlantic and Gulf Coastal Plain aquifers

Groundwater in the Atlantic and Gulf Coastal Plain aquifers is old—more than 21,300 years old in more than half of 252 public-supply wells sampled. That ancient groundwater is more likely to contain concentrations of fluoride, arsenic, and polonium-210 that exceed human-health benchmarks than is younger groundwater, reports a new study...

The Quality of Our Groundwater—Progress on a National Survey

A U.S. Geological Survey study of groundwater quality across the nation now includes water-quality information for 15 of the most heavily used aquifers in the nation.

Water quality of rivers has changed dramatically in human-dominated landscapes of the United States

Human activities have markedly changed the water quality of rivers in the past few decades according to a new study by the U.S. Geological Survey—concentrations of some water- quality constituents have increased while others have decreased.

Colorado River Flow Dwindles as Warming-Driven Loss of Reflective Snow Energizes Evaporation

New USGS research indicates that streamflow in the Upper Colorado River Basin (UCRB) is decreasing by about 5% per degree Fahrenheit as a consequence of atmospheric warming, causing a 20% reduction over the past century.
