Soil Characteristic Depth
Deep Soil = Excellent Treatment
Shallow Soil = Poor Treatment
Determines the volume of soil a pollutant must travel through before reaching the groundwater.
Determines the time a pollutant is in contact with a soil.
The processes of filtration, adsorption and absorption, biodegradation, and volatilization are more effective in deep soils.
Shallow soils can adsorb only a limited amount of pollutant.
