Table 6--Results of pumping tests made on wells in Scott County, Kansas, using the Theis recovery method for determining permeability.

Well No. Water-bearing formation Discharge, gallons a minute Drawdown, feet Duration of pumping, minutes Specific capacity (1) Coefficient of transmissibility Approximate thickness of water-bearing material, feet Coefficient of permeability (2)
91 Pleistocene sand and gravel and/or Ogallala formation 666 24.86 195 26.8 46,270 38 1,200
137 Pleistocene sand and gravel and/or Ogallala formation 580 38.06 185 15.2 79,400 93 850
139 Pleistocene sand and gravel 729 36.20 800 20.1 10,300 54 190
172 Pleistocene sand and gravel 567 34.83 197 16.3 17,010 60 280

1. The specific capacity of a well is its rate of yield per unit of drawdown and is determined by dividing the tested capacity in gallons a minute by the drawdown in feet.
2. Coefficient of transmissibility divided by thickness of saturated water-bearing material; water temperature 60° F.; hence no correction for temperature is needed.
