How far apart must the soil borings be located?

In the context of conducting soil borings for private sewage systems in Illinois, understanding the appropriate distance between borings is crucial for obtaining accurate and representative data about the soil conditions. The correct distance of 50 feet apart is established to ensure that the assessment of the soil's behavior and characteristics is comprehensive and reflects the variability that can occur within a given area.

This distance allows contractors to gather sufficient information about the soil's texture, composition, permeability, and other factors that influence the design and installation of septic systems. When soil borings are spaced too far apart, there is a risk of missing significant changes in soil conditions that could impact the performance of the septic system. Conversely, spacing them too closely could lead to redundant information without providing the added value of greater coverage.

Overall, maintaining a distance of 50 feet between soil borings strikes an ideal balance, ensuring thorough and effective analysis while optimizing the efficiency of the investigation process.
