The only publication to fully present the problems and solutions to the complicated issue of contaminated rock site remediation, ""Remediation in Rock Masses"" provides theoretical analyses, case studies, and recommendations by prominent individuals in the field. This book presents a comprehensive overview of modeling, site characterization, and remediation techniques, including fundamental principles and practical techniques for characterizing polluted rock masses, estimating contaminant flow rates in rock, and assessing the effectiveness of important cleanup technologies for contaminated rock sites. Other topics include theoretical modeling of liquid movement and mixing in rock fractures; evaluations of pneumatic and hydraulic fracturing to increase formation permeabilities; and remediation technologies, including pump-and-treat, soil vapor extraction (SVE), bioremediation, and alcohol flooding. The occurrence of contaminants - gasoline, trichloroethylene (TCE), tetrahydrofuran, and heavy metals - in fractured rock systems at selected industrial sites, landfills, and hardrock or coal mining sites is reviewed. Site characterization techniques to determine interconnectivity between fractures are also discussed.
