Pumping test to obtain aquifer transmissibility coefficients; aquifer was poorly cemented St. Peter sandstone; time-drawdown graphs showed correct aquifer transmissibility, whereas distance-drawdown graph showed distorted value; distortion was caused by enlargement of boreholes and, physical connection between nearest observation well and pumped well; calculations based on amount of sand removed, showed presence of large cavities and obvious physical connection between 2 boreholes.
