TCEQ OSSF (Course Review) - Questions & Solutions
In the hydrologic cycle, water moves by evaporation and transpiration into
the ___________________ where it comes in contact with cooler air, condenses, and
falls to the ground in the form of _____________________ (sleet, snow, hail or rain),
and the surface water supply through _____________________. Right Ans -
Atmosphere, Precipitation, Runoff
The term ___________ _____________ refers to water that collects beneath the
surface of the earth in porous, permeable, water-bearing geologic formations
or aquifers. Right Ans - Ground Water
The term __________ _____________ refers to water that is found above ground in
containment areas, such as lakes, rivers, streams, creeks and reservoirs.
Right Ans - Surface Waters
Water table aquifers are recharged by ___________ __________________. Right Ans
- Local Percolation.
Rock-filled or lined pits dug at least 4 feet deep at the end of a septic tank
absorption field system are called _________ _________. Right Ans - Seepage
Pits.
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 waste water are
called __________________. Right Ans - Cesspools.
How are water born diseases transmitted? Right Ans - Microorganisms
What are 3 primary routes of containment for pathogenetic microorganisms
and harmful chemicals from on-site sewage systems to our environment?
Right Ans - Neighborhood pollution, groundwater pollution and surface water
pollution.
What problems are a result of neighborhood pollution? Right Ans -
~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.
~Feuds and bad relationships with neighbors that can result from waste
water problems.
~Property values drop and real estate transactions fall through. No one
benefits and everyone suffers when neighborhoods are fouled by waste water.
Why is acceptable quality water vital? Right Ans - Sustains human life, the
natural environment and the economic life of Texas
Groundwater that is obtained via a well can be used for what purpose?
Right Ans - Agricultural, industrial/commercial and drinking water.
What is the difference between a water table aquifer and an artesian aquifer?
Right Ans - Water table aquifer is in direct contact with either the soil or the
intermediate belt.
Artesian is overplayed by a layer of impervious material.
What is the static water level? Right Ans - Level at which water stands in a
well.
What are the 2 categories of sources of pollutants in surface water? Right
Ans - Point source pollution.
Non-point source pollution.
What is the difference between point source and nonpoint source pollution?
Right Ans - Point source can be controlled, non point source has little or no
control.
Ground water quality is recognized as a minor problem in Texas. Right Ans
- FALSE
