Question 10

The PRIMARY purpose of percolation tests and test borings is to determine whether the absorption capacity of the soil is sufficient for intended use.

Percolation tests and test borings are primarily conducted to assess the soil's ability to absorb water, which is crucial for various applications such as septic system design and drainage planning.

A) the absorption capacity of the soil is sufficient for intended use.

This option is correct because percolation tests directly measure the rate at which water is absorbed by the soil. This information is essential for determining whether the soil can adequately support the intended use, particularly for systems that require appropriate drainage or filtration.

B) a reinforced footing or foundation should be used.

This option is incorrect as the primary purpose of percolation tests is not to assess the need for reinforced footings or foundations, but rather to evaluate the soil's absorption capacity. While soil stability can influence foundation design, this is not the main focus of percolation testing.

C) a particular type of well is drilled to a sufficient depth.

This option is also incorrect. Percolation tests do not specifically address well depth; rather, they focus on the soil's absorption properties. The depth of a well may be determined by other geological assessments, but it is not the primary intent of percolation testing.

D) the building inspector should issue a building permit.

This option is incorrect as well. While percolation tests may inform decisions related to building permits, they are not conducted to determine whether a permit should be issued. The tests are specifically aimed at understanding soil absorption capacity, which is a separate concern from the permit process.

Conclusion

In summary, option A is definitively correct as it directly addresses the primary purpose of percolation tests and test borings, which is to measure the soil's absorption capacity. All other options fail to capture this essential function, focusing instead on unrelated aspects of construction and soil assessment.
