Wells and Septic Systems
Groundwater is the water in saturated soils and the rocks under the soil. It is the source of most of the fresh water available for human consumption drawn through wells. Groundwater is recharged through percolation of surface water sources and moves, often slowly, due to gravity towards surface water bodies. It is vulnerable to pollution from surface activities, including improperly designed or installed septic systems.
