Wisconsin Mound Soil Absorption System and Area FillPractice Exam

What must be done with any visible boulders during site preparation?

1. Leave them untouched

2. Remove them from the area

3. Cut them down to ground level

4. Cover them with soil

The correct answer is: Remove them from the area

During site preparation for a Wisconsin Mound Soil Absorption System and Area Fill, it is essential to remove any visible boulders from the area. This is important because boulders can interfere with the proper installation and functioning of the system. Their presence can disrupt the soil structure, impede water movement, and limit the effective area needed for absorption. Ensuring that the site is clear of such obstructions optimizes soil conditions, enhances the performance of the absorption system, and helps prevent future maintenance issues. In contrast, leaving boulders untouched or simply cutting them down to ground level does not eliminate their impact on soil permeability or system functionality. Covering boulders with soil could give a false sense of security, as they would still pose a risk of obstruction beneath the surface. Therefore, the most effective and recommended practice is to remove them from the area entirely to facilitate successful system performance.
