In a monitoring well installation, where is the filter pack placed relative to the screen?

Explanation:
The filter pack is placed above the screen. This arrangement creates a filtration zone around the intake that protects the screen from sediments and helps keep the well from clogging. By sitting immediately above the screen, the granular material around the screen filters water before it enters the perforated intake, stabilizes the screen, and supports proper sampling.
