A warming climate and low-oxygen from Chesapeake Bay will reduce oxygen more than nutrient reductions will increase it in the Chester River.
After decades of abuse, new research and a floating wetland point toward a healthier future for the Charles River.
While focusing on ocean-specific threats to corals, researchers miss a dangerous, world-wide flow of sewage from land.
Two data buoys recently deployed in the shoals of San Francisco Bay could be filling the important data gap on the local impacts of nutrient loading.
A nationwide look at 15 water quality constituents, by the U S Geological Survey, reveals evolving concerns in American rivers.
The Montana Department of Environmental Quality is studying why a native species of algae is covering one of the state’s most popular rivers.
An underwater buoy designed to work even while locked in ice monitors physical conditions in Wilson Lake, Maine.
USGS scientists are working to find out why filamentous algae is plaguing the Buffalo River, and how to stop it.
Recent research shows how diatoms can reveal how impaired water quality is, and perhaps help even laypeople monitor for water quality.
In partnership with over 30 cities, the USGS is now monitoring the Mississippi River in real-time, offering more meaningful data to scientists and the public.
Recent research tests the effects of multiple contaminants—two kinds of nanomaterials and nutrient pollution—on the eutrophication process in water.
A team has found that nutrient pollution accelerates acidification of coral reefs, directly impacting them and pushing them toward a net loss.
Researchers have found that beavers building dams in a natural landscape improve water quality significantly by removing sediment and nutrients from water.
The IL Nutrient Loss Reduction Strategy is generating interest and improving water quality by reducing nutrient runoff into Illinois watersheds.
As scientists monitor a mining waste cleanup in a deep lake with unusual water dynamics, they learn more about how these dynamics impact remediation efforts.
Researchers have identified a microbe that breaks down ammonium, a common component in fertilizer and sewage runoff, without oxygen.
A recent study reveals that best management practices for impaired Grand Lake St. Marys has resulted in much less runoff and lower nutrient levels.
A team of researchers is refining our understanding of wastewater treatment with microalgae, producing a sustainable source of energy and treatment.
Researchers reveal that the Atlantic Meridional Overturning Circulation (AMOC) is weaker than it’s been in 1,600 years—and why.
New research shows the rapid, cascading effects a single degree of warming has caused in the world’s largest High Arctic lake.
