BETHLEHEM, Pa., March 13 /PRNewswire/ -- At a size 1,000 times thinner 
than a human hair, magnetic nanoparticles are easy to
overlook. But add the minute Herculean particles to contaminated 
groundwater, and they may just change the world. 

So says a team of environmental engineers who have pioneered and tested 
a new technology using nanoparticles that can cleanse
polluted underground aquifers that provide drinking water to an 
increasingly thirsty world. 

Wei-xian Zhang, associate professor of civil and environmental 
engineering at Lehigh University, Bethlehem, Pa., has a patent pending 
for his remediation method and has licensed the technology to two 
environmental companies. He also recently received a grant from the U.S. 
Environmental Protection Agency to explore the potential for using 
nanoparticles to treat hazardous waste.
