You answer to Question 8 was incorrect. To estimate the average porosity::
- Compute the Main Aquifer thickness
- Compute the thickness of each interval of the Main Aquifer described in the driller's log.
- Assign a porosity value to each interval of the Main Aquifer described in the driller's log.
- Using the calculator utility on your computer, compute a weighted average porosity.
