This equals 50 feet of hole <br />material for each hole with a 10 foot above water <br />level fill requirement. 10 holes x 50 feet = 500 feet <br />x a nominal 5" diameter hole (_ .136 ft3/borehole ft) <br />=68.0 ft3 of bentonite pellets needed. According to <br />Baroid charts, each 5" diameter borehole foot needs <br />9.67 pounds of 3/8" pellets for sealing. 500 x 9.67 <br />= 4,835.0 pounds. Pellets are sold in 50 bags at a <br />cost of about $10/bag. 4,835.0/50 = 96.7 x $10 =$ 967.00 <br />Hole Plugging <br />10 borehole ft x .136 ft3/borehole ft = 1.36 ft3 <br />1 80# of dry mix concrete = .66 ft3 <br />each drill hole plug will need 2.06 bags (say 3) <br />3 bags x $4.50 ea = $13.50 x i0 holes = $ <br />135.00 <br />Labor for sealing and plugging <br />1 person @ $15.00/hr x 16.00 hrs = $ <br />240.00 <br />Subtotal $ <br />1,585. <br />00 <br />Misc.
