Water Treatment System looking East Panoramic of the tank after all the material had been removed. There is liquid remaining. Panoramic of the vault (pad) south of the tank. Site excavation on the S side of the main tank. Six test pits were made around the W, N, and E sides to depths of 3 ft. Oil observed in 4 of the 6 pits. The two southern pits were not contaminated with bunker C or waste oil. Clarity of effluent water coming from carbon filtration system. TEPH, VPH, and SVOC results are all non-detect. excavation west side of bunker c tank excavation and nw corner tank breakup breaking out the bottom of the former tank to assess contamination underneath. dewatering the South end of the excavation so that the excavation can be completed. South end of the excavation. START member Miller is 6 feet tall for reference. Soil beneath the tank. Note heavy staining. Backfilling the south end of the excavation and installation of a dewatering trench. Site overview. Looking from Northeast to Southwest. The pit is being used as an infiltration pit for management of groundwater. It will be excavated/remediated as part of the clean up. Expanded infiltration pits. Removal of the concrete tank. Excavation of the saturated material underneath the tank. continued excavation of the saturated material beneath the tank.
