  • Well pipe extraction apparatus
    Patent number: 6615919
    Abstract: A well pipe extraction apparatus for removing a groundwater monitoring well consisting of PVC pipe from the ground. The well pipe extraction apparatus includes a wire rope, a soft eye formed at an upper end of the wire rope and knurled brass rod attached to the opposite end of the wire rope. The knurled brass rod is lowered to the bottom end of the well casing. An operator pours sand particles down the well casing.
