Using the following well spec information and the slug test data, use Hvorslev method to estimate the hydraulic conductivity in the aquifer surrounding each of the 4 monitoring wells (TW2, TW3, TW5 and TW6). Assume that during each slug test, a pressure transducer was placed at the bottom of the well casing, a volume of water was removed from the well, and the head above the transducer was recorded as a function of time. Assuming that the wells are located in the same aquifer, comment on the heterogeneity of that aquifer. What might explain your results?
