The system consists of 1 A Soil Bentonite cutoff barrier keyed into bedrock, 2 15 dewatering wells, 3 21 recharge wells, 4 17 piezometers, and 5 a carbon adsorption treatment plant. Foundation explorations included soil borings, bedrock sampling, ground water hydrology testing, and bedrock and soil permeability tests. Investigations during construction included visually logging well cuttings, inspection of excavated slurry trench materials, blast hole drilling, and slurry and backfill testing.
