A critical site evaluation procedure determines the suitability of soil for a subsurface wastewater disposal system. The method assesses the rate at which water is absorbed into the ground. For instance, a soil sample with a high clay content will generally exhibit a slower absorption rate than sandy soil. This assessment is fundamental in determining the size and design of a wastewater system to ensure proper functionality.
This evaluation is paramount in preventing environmental contamination and safeguarding public health. Historically, failures in wastewater systems have resulted in the pollution of groundwater and surface water resources. Accurate assessments help to minimize the risk of system failure, thereby protecting both the environment and the potable water supply. Regulatory agencies often mandate these evaluations to ensure compliance with environmental protection standards.
