The North Boundary Expansion Project is located at the north boundary of Rocky Mountain Arsenal, Commerce City, Colorado. The system was constructed to contain and treat ground water which has been tainted by organic contaminants produced at the arsenal. The system consists of 1 A bentonite slurry cutoff barrier keyed into bedrock, 2 48 dewater wells, 3 26 recharge wells, 4 39 monitor wells, and 5 a carbon absorption treatment plant. Foundation explorations include soil borings, bedrock sampling, geophysical logging, ground water hydrology testing and modeling, and bedrock and soil permedability. Keywords Organic contaminant Bentonite slurry cutoff barrier Ground water hydrology Permeability Transmissivity Dewater wells Recharge wells Treatment system Bedrock Excavation.
