This equals 50 feet of hole <br />material for each hole with a 10 foot above water <br />level fill requirement. 11 holes x 50 feet = 550 Feet <br />• x a nominal 5" diameter hole (_ .136 ft3/borehole ft) <br />=74.80 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. 550 x 9.67 <br />= 5,318.5 pounds.
