GROUNDWATER
POLLUTION
Interactions
between groundwater and surface water are complex. Consequently, groundwater
pollution, sometimes referred to as groundwater contamination, is not as easily
classified as surface water pollution. groundwater aquifers are susceptible to
contamination from sources that may not directly affect surface water bodies,
and the distinction of point vs. non-point.By its very nature, directly
affect surface water bodies, and the distinction of point vs. non-point source
may be irrelevant. A spill or ongoing releases of chemical or radionuclide contaminants
into soil (located away from a surface water body) may not create point source
or non-point source pollution, but can contaminate the aquifer below, defined
as a toxin plume. The movement of the plume, called a plume front, may be
analyzed through a hydrological transport model or groundwater model. Analysis
of groundwater contamination may focus on the soil characteristics and site
geology, hydrogeology, hydrology, and the nature of the contaminants.
