Full Description

The atmosphere is a vector for a variety of materials that may impact source waterquality. These materials can be divided into two groups: man-made impacts andnaturally-occurring impacts. Man-made impacts can include chemicals released as aresult of industry and agriculture, radioactive fallout, and even the use of a variety ofwarfare agents. Natural hazards can include pathogenic microbes, toxic metals, andnutrients.These airborne materials, regardless of their origin, may impact source watersduring short or long range atmospheric transport. Short range atmospheric inputs arearbitrarily defined here as those traveling less than 10 kilometers from their source. Longrange atmospheric threats, are transported much further by winds, storm systems, oraerosolized soil dust. This paper focuses on the authors' work on African desert dust, which is atype of windblown contaminated soil that has long range effects. Includes 20 references.
