NEW OSSF INSTALLER 1 AND 2 ACTUAL EXAM
QUESTIONS WITH ANSWERS NEWLY MODIFIED
EXAM
Why is acceptable quality water vital? -- ANSWER--No resource in Texas or
elsewhere is more valuable than water. Acceptable quality water is not only
vital in sustaining human life, but is also vital in sustaining the natural
environment and the economic life of Texas.
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
Static water level -- ANSWER--Level at which water stands in a well
Two categories of sources of pollutants in surface water -- ANSWER--Point
source pollution
Nonpoint source pollution
1
,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--Rock-filled or lined pits dug at least 4 feet deep at the
end of a septic tank absorption field system are called
In the hydrologic cycle, water moves by evaporation and transpiration into the -
- ANSWER--Atmosphere
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.
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
2
,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
What problems are a result of neighborhood pollution? -- ANSWER--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.
Property values drop and real estate transactions fall through. No one benefits
and everyone suffers when neighborhoods are fouled by wastewater.
Point source vs non point pollution -- ANSWER--Point source comes from
specific locations through discharge structures (pipes or ditches). Can be
monitored, controlled, and inspected
3
, Nonpoint source is intermittent, dispersed flow that escapes from pollution
sources with little or no control
Groundwater quality is recognized as a minor problem in Texas. -- ANSWER-
False
Cesspools and seepage pits are legal systems in Texas and may be installed. --
ANSWER--False
Bore holes and injection wells are legal in Texas and may be installed. --
ANSWER--False
Artesian aquifers can be contaminated by bore holes and injection wells. --
ANSWER--True
In America, laws can be successfully enforced only when the majority of
citizens voluntarily comply. -- ANSWER--True
Homeowners should be educated the need for and importance of maintaining
their OSSF system. -- ANSWER--True
On-site sewage facilities (OSSF) have been regulated statewide since --
