Neighborhood pollution
Groundwater contamination
Surface water pollution - -answer--What are the three primary routes of contamination for
pathogenic 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 wastewater.
Vectors, such as roaches and flies, that can also spread diseases after coming in contact with
the wastewater.
Unsightly and unpleasant living conditions that result from the standing wastewater and
odors.
Feuds and bad relationships between neighbors that can result from the wastewater
problems.
