Small Fish Detect Big Problems
Researchers are using
bluegills to detect
industrial and agricultural
spills in water supplies.
Changes in the environment
cause the fishes' behavior
and breathing patterns to

Testing Water
Playing a role once reserved
for environmental engineers,
children are now helping to
test the health of water in
their local communities. A
new kit comes equipped with
everything needed to test
the water's temperature, oxy ... > full story
Nanotechnology - Cleaning Up Our Water
Chemical engineers created
nanoparticles out of gold
and palladium to break down
pollutants in groundwater.
Adding the particles to
groundwater converts
dangerous contaminants like

Safer Water Worldwide
Industrial toxicologists at
a non-profit venture founded
by Procter & Gamble
developed PUR, a water
purifier that combines a
flocculant -- which
separates particles and
organisms from water -- and

New Software Helps Track the Path of Toxic Spills
Ecological engineers have developed software that can model the path of a toxic spill in waterways anywhere in the United States. The system can predict if and when a contaminant will reach a ... > more -
The Science Behind Wave Pools
Scientists gives us a sneak peek into the world of wave pools, and explain how these huge pools make constant waves. Waves are made by a huge compressor that feeds four gigantic air blowers. Then a ... > more -
Atmospheric Chemists Show Morning Fog Captures Particulate Matter
While it hassles commuters, morning mist removes a lot of airborne particles which are hazardous for people with respiratory health problems. The water droplets inside morning fog are of just the ... > more -
Physical Chemists Devise Quick Spectrometry-Based Mercury Test
Physical chemists have created a new, cheap test to detect mercury, an element known to harm the brain, kidneys, heart, lungs and immune system. A gold nanorod absorbs mercury from a sample and, then ... > more -
Scientist Measures Land Used by Lawns
Using census data, satellite images, aerial photographs, and computer simulations, a NASA scientist estimated that turf grass is the single-largest irrigated crop in the United States, three times ... > more -
Soil Scientists Stabilize Fire Ravaged Topsoil With New Technology
Chemists and engineers designed a technology that protects soil. A polymer encased in recycled paper bonds to positive ions in soil to form clumps. These clods of dirt break up the hard surface that ... > more -
Seismologists Devise New Technique To Measure Pollution
Seismologists have tested a new way to measure the concentration of the dangerous groundwater contaminant Trichloroethylene (TCE). Ultrasonic waves called P-waves are sent through ground containing ... > more -
Soil Scientists Restore Marshes To Protect Coastal Ecology
Soil scientists spread material dredged from shipping channels over shore areas to help rebuild marsh areas. Wetlands along the shore protect the land from storm surges, create habitat for wildlife, ... > more -
Civil Engineers Learn from Dutch Flood Barrier System
A group of U.S. civil engineers and city officials went on a recent trip to the Netherlands -- a country much of which is below sea level -- to study the country's storm surge barrier system. The ... > more -
Environmental Engineers Link Contamination Levels to Tides
By washing decomposing plants into the ocean, high tides could contribute to the increased levels of Enterococci that are often responsible for beach closures. Scientists have now established a clear ... > more
