MICROORGANISMS
How are water born diseases transmitted?
Neighborhood pollution, groundwater pollution and surface water pollution.
What are 3 primary routes of containment for pathogenetic microorganisms and harmful
chemicals from on-site sewage systems to our environment?
~Diseases that can be spread by direct or indirect contact with the standing water.
~Vectors such as roaches and flies, that can also spread diseases after coming in contact with the
waste water.
~Unsightly and unpleasant living conditions that result from the standing waste water.
