PTFIT automatically interprets pumping test data and gives a measure of the goodness of fit.
With PTFIT large diameter wells pumping in leaky aquifers can be analysed. The Theis, Jacob, Hantush (leaky aquifer) and Papadopulos methods are all special cases of the general solution used by the software. It is the only method we know which can cope automatically with multi-rate pumping regimes.
The software works on windows 95/98/ME/XP. For reading help files you need word 97 (not essential) for auto graphing of PTFIT output you need Excel 97 (although not essential).
