Soil contamination

Soil contamination is the presence of man-made chemicals or other alteration to the natural soil environment.

This type of contamination typically arises from rupture of underground storage tanks, application of pesticides and herbicides, percolation of contaminated surface water to subsurface strata, leaching of wastes from landfills or direct discharge of industrial wastes to the soil.
