Groudwater as a resource takes the most important place in water supply. Aquifers are non homogeneous and parameter identification is very important problem in groundwater analysis. Pumping test is an experiment for transmissivity and storage coefficient identification based on well and piezometer drawdowns measured in situ. Unfortunately, some disturbing factors make measured data unreliable. An attempt has been made to estimate reliability of Mediana aquifer parameters based on large diameter well Bn6/2 pumping test results. Observation wells data were plotted on semi-log paper and parameter values estimated. After that, pumping test numerical simulations were performed, accounting for some disturbances. Numerical analysis of pumping test data have provided more reliable results.
