Groundwater Flow Model Development at the Nevada Test Site
The Underground Test Area Project (UGTA) of the National Nuclear Security Administration.s Nevada Site Office is in the process of assessing and developing regulatory decision options...

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...

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...

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...

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

Foundations in Carbonate Rocks and Karst

Preliminary Assessment of Bacteria Abundance in Rivers of the Pantanal Wetlands -- Brazil
Heterothrophic bacteria play an important role in the carbon flux of aquatic environments, specially in flooded areas, where they are considered to be a source of organic matter. They...

Water Yield Responses to High and Low Spatial Resolution Climate Change Scenarios in the Missouri River Basin
Water yield responses to two climate change scenarios of different spatial scales were compared. Responses were determined by applying the Soil and Water Assessment Tool (SWAT) hydrologic...

A Constructed Wetland for Wastewater Treatment in the Coachella Valley, Indio, California
The Coachella Valley Wild Bird Center (CVWBC) proposed a wetland habitat site on 22 acres property in India, California, under lease from Valley Sanitary District. The District currently...

Taking Treatment to the Extremes
Designing a wastewater treatment facility that meets current environmental guidelines can be challenging enough. But designing it so it can be shipped, constructed, operated, and maintained...

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...

Concrete Connections
A new application of polymer composites involves the repair and rehabilitation of reinforced concrete frame connections. Test results from a pilot study conducted at the California State...
