OSSF INSTALLER 1 EXAM
QUESTIONS AND ANSWERS
(GRADED A+)
In the hydrologic cycle, water moves by evaporation and transpiration into the -
ANSWER-Atmosphere
evaporation where it comes in contact - ANSWER-
Ground Water - ANSWER-The term refers to water that collects beneath the surface
of the earth in porous, permeable, water-bearing geologic formations or aquifers.
Surface water - ANSWER-refers to water that is found above ground in containment
areas, such as lakes, rivers, streams, creeks, and reservoirs.
Water table aquifers are recharged by - ANSWER-Local percolation
Sepage pits - ANSWER-
sepage pits - ANSWER-Rock-filled or lined pits dug at least 4 feet deep at the end of
a septic tank absorption field system are called
Cess pools - ANSWER-Pits constructed in permeable soil with open-jointed material
along the sides to the bottom of the pit that receive a direct discharge of raw
wastewater are called
How are waterborne diseases transmitted? - ANSWER-Microorganisms (pathogens)
that live in the intestine are passed in the feces and get into the water supply
What are the three primary routes of contamination for pathogenic microorganisms
and harmful chemicals from on-site sewage systems to our environment? -
ANSWER-Neighborhood pollution
Groundwater contamination
Surface water pollution
Ground water that is obtained via a well can be used for - ANSWER-Drinking,
industrial, or agricultural
Water table aquifer vs artesian - ANSWER-Water table aquifer - direct contact with
either soil or the intermediate belt
Artesian aquifer - overlaid by a layer of impervious material that recieves little or no
recharge throigh this confining layer
What problems are a result of neighborhood pollution? - ANSWER-Diseases that
can be spread by direct or indirect contact with the standing wastewater.
