The time drawdown data listed below for a confined aquifer was measured at an observation well located 300 ft away from a well pumped at 1500 gpm. Determine T and S for the aquifer using the Cooper-Jacob method of solution. For the T and S values that you obtained, after how many minutes of pumping is the Cooper-Jacob approximation valid
