Soil testing evaluates the quality, condition, and composition of your soil. It is a crucial part of determining if a septic system has failed, if repairs or a new system are needed, or if the ground is suitable for a septic system when building new construction. Below, learn more about soil testing and what it involves.

Answers to Common Soil Testing Questions

What does soil testing entail?

The state of Wisconsin previously required perc tests to determine a site's suitability for a septic system. During this test, a specific amount of water was poured into holes and measured for a specific amount of time to find how far into the ground it would penetrate. 

Now, the process starts by digging a minimum of three pits at least eight inches deep with a backhoe. The tester goes into each pit and identifies the horizon in the soil profiles. This assesses the depth and boundaries of horizons; the type, consistency, and structure of the soil; and the presence of any root systems in the ground.

Why do I need soil testing?

The results tell you what septic system size, type, and design is most suitable for your property. This ensures that the septic structure can adequately handle the needs of the household. It also keeps you in compliance with the law, as completed soil tests are filed with the county planning and zoning department.

What are the ideal soil conditions for a septic system?

Soils with high sand and gravel content drain the best, while those with excessive clay or solid rock are least effective. Most ground conditions contain a mixture of all of these elements, so you can likely expect the results to fall somewhere in the middle of the spectrum. But, in general, the better the soil drains, the more ideal it is for a septic system.

Who can perform soil testing?

In Wisconsin, only certified soil testers can conduct the necessary procedures. They also must approve and sign off on the results before the tests are filed with the county.
