Wisconsin Mound Soil Absorption System and Area FillPractice Exam

Which side of the site should all work be performed from?

1. Downslope

2. Upslope

3. Side slope

4. Drainage slope

The correct answer is: Upslope

The correct choice is to perform all work from the upslope side of the site. This is essential because conducting work from the upslope position helps prevent soil erosion and sedimentation in lower areas of the site, particularly important when dealing with systems like the Wisconsin Mound Soil Absorption System. By working from the upslope, you minimize the disturbance of soil in lower areas that can occur if digging or construction were to happen from downslope positions. Working from the upslope also facilitates proper drainage and ensures that any water runoff during the construction process is directed away from the work areas and into drainage systems that may be in place. This approach helps maintain the integrity of the soil absorption system, which relies on proper water management for its functionality. In contrast, working from downslope could lead to increased erosion and the potential for sediment to disrupt the absorption system. The side slope and drainage slope options are less favorable as they could similarly contribute to erosion issues or complicate water management during the work. Thus, the upslope choice is the most effective method for protecting the site during any necessary work.
