This <br /> CPA is for the removal and disposal for the total amount,22 soil drums and 15 water drums. <br /> The work proposed here is just the arranging,coordinating,supervision and disposal of these drums. <br /> -_ The opinion of cost for this work is$4,015. <br /> Proposed Bidding of Project <br /> Del-Tech Geotechnical Support Services bid a unit cost of$70 per drum for the disposal of the soil and Nor Cal Oil, <br /> a petroleum recycler, bid a unit cost of$1.35 per gallon for the disposal of the rinse and purge water.
