What is the minimum distance required between a septic system and a water source in South Carolina?

In South Carolina, the minimum distance required between a septic system and a water source is indeed 100 feet. This regulation is in place to ensure the protection of groundwater and water quality. The rationale behind this distance is to minimize the risk of contamination from septic effluent entering any nearby water sources, such as wells or surface water bodies. Contaminants from a septic system can potentially leach into the soil and reach the water source, posing health risks to humans and the environment.

The requirements set by state regulations take into account factors such as the type of soil, topography, and hydrology of the area, all of which can affect how contaminants travel through the environment. Therefore, maintaining a buffer zone of 100 feet is a precautionary measure aimed at safeguarding public health and the ecosystem.
