Modeling Fort Ord Site OU2's Remediation System Using Optimization
Fort Ord.s Site OU2 is located approximately 80 miles south of San Francisco near Monterey Bay in Monterey County, California. Fort Ord contains two landfills which were used for residential...

It's a Bug's Life — Enhanced In-Situ Bioremediation of Chlorinated Solvents in Groundwater

Nanotechnology Takes Roots
Nanoscale particles of zero-valent iron with a trace of noble metal catalyst are punching well above their weight in the area of environmental remediation. Their ability to destroy a wide...

Fate of TCE in Phytoremediation Systems
The phytoremediation of trichloroethylene (TCE) and other volatile organic compounds (VOCs) has been developed from a mere concept to full applications over the past decade. However, the...

Nonionic Organic Solute Sorption to Two Organobentonites as a Function of Organic-Carbon Content
Sorption of three nonionic organic solutes (benzene, trichloroethene, and 1,2-dichlorobenzene) to hexadecyltrimethylammonium-bentonite (HDTMA-bentonite) and benzyltriethylammonium-bentonite...

Iron Mountain Mine: Challenge and Success

Examining the Capitol Dome
The dome of the United States Capitol, designed and built from the 1850s to the 1860s, is a masterpiece of 19th-century engineering and construction. The majority of the dome is made of...

Wetlands Treat Mine Runoff
Engineers were asked to design a treatment system for the severely acidic drainage from the Mike Horse and Anaconda metals mines in Montana. Challenges included the mountainous terrain,...
