National Academies Analyze Methods for Capturing, Sequestering CO2

Properties of Biochar-Amended Highway Soils: Biochar – An Eco-friendly Geomaterial
Historically, geotechnical engineers have designed or modified soils and sediments to achieve particular strength, volume change, or flow characteristics. For example, lime and fly ash have been used to...

Becoming Greener with Green Sand: An Iron Castings Company Devises an Environmentally Friendly Liner System Reusing Foundry Byproduct
Metalcasting is one of the oldest methods of recycling—humans have a few millennia worth of experience with the technique—but today's industry still battles public preconceptions...

Remediation System Optimization with Alternatives
This work applies the enhanced multi-objective robust genetic algorithm (EMRGA) (Beckford and Chan Hilton, 2004) to Fort Ord's Site OU2 for optimal groundwater remediation under uncertainty....

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...

Atmospheric Corrosion Resistance of Structural Steels
The main objective of this paper is to provide engineers with data on thickness loss of structural steel members resulting from corrosion. To this end, the writers have collected atmospheric...

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...

Amino Acid Geochronology Applied to the Dating of Eolianites on San Salvador Island, Bahamas
Using amino acid racemization data measured on carbonate eolianite sediments, we assess the ability of amino acid geochronology to distringuish among several stratigraphic units on San...

Granular Activated Carbon/Biological Activated Carbon

Larger Foraminifers as Contributors to Carbonate Beach Sands
Larger foraminifers are locally significant contributors to tropical carbonate sediments, particularly in the Indo-Pacific region. The two major factors influencing foraminiferal production...

Amino Acid Geochronology Applied to the Dating of Eolianites on San Salvador Island, Bahamas
Using amino acid racemization data measured on carbonate eolianite sediments, we assess the ability of amino acid geochronology to distringuish among several stratigraphic units on San...

Characteristics and Implications of Relict Carbonate Paleoshorelines
Throughout the Florida-Bahamas region, the accumulation of coastal carbonate deposits, excepting the present highstand, appears to be episodic. Back through time these deposits provide...

Iron Mountain Mine: Challenge and Success

A Large Scale Gridded Application of the CALINE4 Dispersion Model

Battling Concrete Corrosion
For decades engineers have fought concrete corrosion, but few methods have offered a long-term solution—until now. Electrochemical techniques such as electrochemical chloride extraction...

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,...
