Which of the following is not satisfactory for site preparation?

Backhoe bucket teeth
Mold board plow
Chisel plow
Rototillers

The correct answer is: Backhoe bucket teeth

In the context of site preparation for soil absorption systems, backhoe bucket teeth are not considered satisfactory because they can lead to excessive compaction of the soil. This compaction restricts the soil's ability to facilitate water drainage and proper absorption, which are crucial for the effective functioning of the system. In contrast, tools such as a moldboard plow, chisel plow, and rototillers are designed to adequately prepare the soil by aerating it and mixing in organic material, which enhances drainage and absorption properties. These tools break up the soil structure without causing significant compaction, making them suitable for creating the necessary conditions for a successful site preparation. Therefore, using a backhoe with sharp teeth is typically avoided because it does not align with the objectives of ensuring proper soil conditions for absorption systems.
