A-S Aron-Scott method of analyzing variable discharge pumping tests
CPB Cooper, Papedopolous end Bredehoft method of analyzing data from slug tests
0 Discharge, in gallons per minute
T Trensmissivity, in feet squared per day
K Hydraulic conductivity, in feet per day
S storativity, uni[less
Notes: (a) Slug injection tests, thus there is no pumping rate
(b) The Cooper-Papadopul os slug test technique does not yield storage coefficient
values with any accuracy because there is so little spacing between type
curves that are each en order of magnitude different
(c) No pumping rate is reported as these wells were used es observation wells
during the pumping tests. All other wells, excepting those marked with (a),
rare pumping wells during the aquifer tests for the dates listed
(d) Transmi ssivity value for TLS is suspect because annular space between the
boring end casing is flowing et the Around surface (well seal failure) end the
. value is 100 times greater than the overburden transmissivities measured et
YOV9, YOV28, end YOV30.
