For slopes where seeps may occur from soil absorption systems, what is the recommended minimum distance?

The recommended minimum distance of 25 feet for slopes where seeps may occur from soil absorption systems is based on the need to manage and mitigate the risks associated with groundwater contamination and the effectiveness of the absorption field. The reasoning behind this distance is to ensure that any effluent from the soil absorption system has adequate separation from potential seep points.

This minimum distance helps prevent the spread of contaminants by providing enough buffer to allow for proper treatment and filtration of effluent as it moves through the soil layers. Proper distances also help to accommodate any variations in groundwater movement and the natural flow dynamics in sloping terrains, making it less likely for effluent to reach groundwater sources or surface water bodies too quickly.

In contrast, options suggesting shorter distances would not meet the requisite safety and regulatory standards that are established to protect environmental and public health. Ensuring a proper distance helps to enhance the overall performance and sustainability of the soil absorption system in managing wastewater.
