Types of Water Pollution
Point source: any single identifiable,
stationary source from which pollutants
are discharged (e.g., a pipe, industrial
facility, or wastewater treatment plant)
Non-point source: pollutant comes from a
broad area and/or many diffuse sources.
Precipitation moving over and through the
ground picks up pollutants.

Classifying Water
Contaminants
Water-soluble
e.g., pesticides, perchlorate, chromium, and
MTBE
LNAPLs, Light Non-Aqueous Phase Liquids
e.g., benzene, toluene, jet fuel, and gasoline
DNAPLs, Dense Non-Aqueous Phase Liquids
e.g., trichloroethylene (TCE), polychlorinated
biphenyls (PCBs)
