a 42.43 m think fractured rock artesian aquifer supplies
waterto a fully penetraing well. before pumping began the
piezometricsurface in the pumping well was observed to be 70.89m
above thebottom confing layer. the pumping rate of the well is
0.0255 m^3/safter 1776 days ofpumping an observation well is
