Volatile organic compounds are compounds that have a high vapor pressure
and low water solubility. Many VOCs are human-made chemicals that are
used and produced in the manufacture of paints, pharmaceuticals, and
refrigerants. VOCs typically are industrial solvents, such as trichloroethylene;
fuel oxygenates, such as methyl
tert-butyl ether (MTBE); or by-products produced by chlorination
in water treatment, such as chloroform. VOCs are often components of
petroleum fuels, hydraulic fluids, paint thinners, and dry cleaning agents.
VOCs are common ground-water contaminants.
