The transmissivity (r) and storativity (S) at each <br /> monitoring poir.'were determined using the computer program Groundwater Analysis Package (GWAP). <br /> This program solves the non-linear equation for radial flow towards a well through a homogeneous parous <br /> medium using the Theis equation. The drawdown data collected in the data logger and manually with the <br /> IP were analyzed with GWAP. To validate the computer results,the data from MW-2 was collected and <br /> ---- - analyzed manually,and.compared to Datalogger data and GWAP analysis The results agree to within 4 <br /> ..L� GROUN171 AT£R <br /> TECHNOLOGY,INC. <br />
