To Include:
1. Prediction of drawdowns with Theis equation - EXCEL, program themselves, I can provide some Visual Basic programs that I have produced
2. Multiple wells - principle of superposition
3. Boundaries - image wells - EXCEL, program themselves
4. EPA Wellhead Capture Zone software (free and on web) - Simple (WHPA - DOS based) and more complex (WhAEM 2000 for Windows)
5. Above solutions still assume homogeneous conditions - more complex simulations with MODFLOW - how wells are represented
