Abstract

Federal legislation restricts the discharge of
waste from various industrial processes into
rivers, lakes, or other waters. For this reason
disposal of wastewater by spraying onto cultivated,
grassed, or forested lands has come into
use. These waste disposal spray systems produce
droplets of water containing suspended
material that may become aerosolized as particles
less than about 20 µ in diameter. Particles
of this size will remain suspended in the
atmosphere and will travel long distances
downwind. The generation of such particles
by commercial spray or sprinkler equipment
may be presumed because regardless of the
size distribution for water droplets leaving the
sprinkler nozzle a number of particles of aerosol
size will develop through rapid evaporation.
Solid materials, including microorganisms, suspended
in the water become the nuclei of the
aerosol particles. Recent reviews have been
published regarding the aerosolization of microorganisms
in sprays resulting from the treatment
and disposal of wastewater from domestic
waste. Microbial aerosol particles were
sampled up to 1.2 km downwind of the spray
source. Katzenelson and Teltch reported
aerosolized coliforms short distances downwind
of spray fields for disposal of wastewater
containing raw domestic waste and for disposal
of effluent from a wastewater settling
pond.
In this report, studies were made of microbial
aerosols downwind from spray fields
for the disposal of potato processing wastewater.
