The following data were collected during the pumping test: . Distance from the well to the observation well (r) = 150 feet Differential drawdown (Ah) in the observation well at this distance = 2.5 feet Aquifer properties: Transmissivity (T) = 25,000 gpd/ft • Storativity (S)- 0.0005 (dimensionless) Pumping time (t) = 5 hours Watch your units !!
