True or False: Soil testing is unnecessary if a site has already been developed.

Soil testing is an essential part of evaluating a site for a septic system, regardless of whether it has already been developed. This is because the soil's properties can greatly influence the effectiveness of the septic system in treating wastewater. Existing developments may have altered the original soil conditions, such as compaction or contamination, which can affect the soil's permeability and ability to filter effluent properly.

Therefore, conducting soil tests helps to determine the soil's texture, structure, percolation rates, and other vital characteristics useful in designing a septic system that functions well and mitigates potential environmental risks. Without appropriate soil testing, there might be a higher chance of system failure or environmental contamination, which could lead to significant health and legal issues. Thus, it is crucial to prioritize soil testing even in developed sites.
