A Probabilistic Approach to Karstic Foundation Variability
Karst is a landscape formed in soluble rocks caused by movement of water that has become slightly acidic. Limestone, dolomite, and gypsum are vulnerable to these influences and may be...

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...

Leachate Chemistry: Its Implications for Clogging
The clogging of leachate collection systems is controlled by interrelated mi and chemical phenomena. Mesocosms containing landfill materials and simulating leachate collection were infiltrated...

Pilot Testing of a Zero-Discharge Treatment Process
As environmental regulations become more stringent, pulp and paper mills are investigating alternatives to conventional biological treatment and discharge of effluents into receiving waters....

Permeability of Clay Liners with Contaminants
Clays are increasingly used as liners for waste disposal facilities. Chemical compatibility studies with hydraulic conductivity tests must be performed to determine the effect of the waste...

Protecting Drinking Water: Rapid Detection of Human Fecal Contamination, Injured, and Non-Culturable Pathogenic Microbes in Water Systems
The rapid, potentially-automatable extraction of filter retentates has allowed quantitative detection of the unique biomarker for human fecal contamination, coprostanol, and the signature...
