can be significant emissions, fuel spills, oil leakages, and so on, from ground support equipment (USEPA, 1996).
During rainfall events, such contaminants are washed off from runways and taxiways, aprons, roads, and parking lots and in the absence of stormwater treatment facilities, are deposited into nearby surface waters Maintenance of runway pavements and rights-of-way nstance, can also through herbicide application for lead to pollution of nearby waters.
Furthermore, during plane loading and unloading, or when aircraft are airborne, pollutants can be released that ultimately find their way into surface waters directly or indirectly (USEPA, 1996)
