ABSTRACT:
A method and apparatus for performing soil percolation tests. A housing member has upper and lower portions, with the lower portion adapted for insertion into a soil percolation test opening in the soil. A depth gauging member is mounted within the housing member for translational movement with respect to the housing member. The soil percolation test opening is filled to a predetermined level with water and the depth gauging member translated to a position indicative of the water level. After a predetermined time the water level in the percolation test opening falls due to absorption by the soil and the depth gauging member is translated to a new position indicative of the new water level. Calibration markings on the housing permit a direct reading of the amount by which the depth gauging member has been translated, which corresponds to the amount the water level in the percolation test opening has fallen. The housing member is also provided with a timer and with facilities for introducing water into the percolation test opening.
