Healthy rivers needed to remove nitrogen
Healthy streams with vibrant ecosystems play a critical role in removing excess nitrogen caused by human activities, according to a major new national study published this week in Nature.   view more (2008-03-13)

New findings blow a decade of assumptions out of the water
The Atlantic Ocean doesn't receive the mother lode of fixed nitrogen, the building block of life, after all. Instead, comparing fathom for fathom, the Pacific and Indian oceans experience twice the amount of nitrogen fixing as the Atlantic.   view more (2007-01-11)

UMCES-led research team quantifies nutrient pollution reductions from urban stream restoration
A team of researchers led by University of Maryland Center for Environmental Science researcher Dr. Sujay Kaushal has been among the first able to quantify the amount of excess nitrogen removed from an urban stream during environmental restoration projects.   view more (2008-05-01)

Smithsonian researchers develop models to assess wetland health
Healthy wetlands perform vital ecological functions in a watershed. But assessing their condition and ability to perform those functions is not easy, especially as wetlands are disappearing fast due to human encroachment.   view more (2007-09-17)

Nitrous oxide from ocean microbes
A large amount of the greenhouse gas nitrous oxide is produced by bacteria in the oxygen poor parts of the ocean using nitrites, Dr Mark Trimmer told journalists at a Science Media Centre press briefing today.   view more (2007-12-11)

Large source of nitrate, a potential water contaminant, found in near-surface desert soils
A UC Riverside-led study in the Mojave Desert, Calif., has found that soils under "desert pavement" have an unusually high concentration of nitrate, a type of salt, close to the surface. Vulnerable to erosion by rain and wind if the desert pavement is disrupted, this vast source of... view more (2008-03-03)

No laughing matter -- bacteria are releasing a serious greenhouse gas
Unlike carbon dioxide and methane, laughing gas has been largely ignored by world leaders as a worrying greenhouse gas. But nitrous oxide must be taken more seriously.   view more (2008-03-31)

ORNL study finds rivers play part in removing nitrogen
Tiny organisms play a powerful role in removing nitrate, a form of nitrogen pollution caused by human activity, in streams, according to a study by a team led by Oak Ridge National Laboratory and published in Nature.   view more (2008-03-13)

Pesticides Persist in Ground Water
Numerous studies over the past four decades have established that pesticides, which are typically applied at the land surface, can move downward through the unsaturated zone to reach the water table at detectable concentrations.   view more (2008-07-02)

Small streams mitigate human influence on coastal ecosystems
Healthy streams play a major role in minimizing the amount of human-generated pollutants, such as nitrogen, that are delivered downstream.   view more (2008-03-13)

From the backyard to the ocean: New study shows streams act as key nitrogen filters
KNOXVILLE -- As spring arrives across the country, tourists returning to beaches will face the reality of "red tide" -- harmful blooms of algae that make water unfit for swimming and pose risks to humans and sea life.   view more (2008-03-13)

How much nitrogen is too much for corn?
North Carolina State researchers recently discovered a test that quickly predicts nitrogen levels in the humid soil conditions of the southeastern United States.   view more (2007-04-24)

Reedbed technology for wastewater treatment:obtaining a better insight through modelling
Constructed wetlands: a green technology for integrated water management The quality of our Flemish surface waters has improved significant during the last decade. Nevertheless, in a densely populated area like Flanders we are still confronted with polluted surface water. The main reason for the... view more (2002-06-11)

Satellite instrument helps tackle mysteries of ozone-eating clouds
Polar stratospheric clouds have become the focus of many research projects in recent years due to the discovery of their role in ozone depletion, but essential aspects of these clouds remain a mystery.   view more (2006-04-11)

Scientists show that streams are critical to preservation of oceanic coastal zones
The plight of the world's oceans is dire, according to recent studies, through insults from human-derived activities depopulating and damaging reefs, altering coastlines, and creating pollutants, such as nitrogen runoff from terrestrial watersheds.   view more (2008-03-13)

Nano design adjustment may help find, clear some water contaminants
Experiments designed to test discrepancies in theoretical computational chemistry have turned up a barely two-angstrom difference that may lead to a new approach to locate and remove dangerous toxins such as perchlorate and nitrates from the environment.   view more (2006-12-14)
