Quiz 4 - Water Quality

1)Sources of ecological impact problems include:

  location and access routes to an airport.

  Construction practices.

  Facility operations.

  Induced development.

  all of the above

2)If correct planning and design procedures are used, airport operations will not adversely affect the local hydrology, that is:

  surface runoff and groundwater recharge rates will be maintained.

  erosion and sediment controls will be used

  the water table and water quality will be maintained.

  all of the above

3)Reduced or low stream flow:

  increases sedimentation.

  increases the concentration of pollutants.

  decreases pollution.

  None of the above.

4)Procedures used to control erosion and sedimentation during construction include all of the following except:

  small check dams.

  relocating stream flow.

  holding basins.

  enlarging or paving channel sections.

  no exceptions; all of the above are correct.

5) The major causes of local flooding resulting from airport construction are:

 an increase in runoff

  alteration of natural drainage

  an increase in bad weather

  none of the above

6)Precipitation either seeps into the earth, runs off in stream flow or evaporates back into the atmosphere. Factors that influence the rate of run off are:

  the nature of the surface (bare, paved, slope).

  type of soil and vegetation.

  type of soil and vegetation.

  none of the above

7) Industrial waste on an airport:

  are treated the same as sanitary wastes

  must be pretreated before entering waste treatment system.

  must be handled separately and should never enter the normal waste system.

  all of the above

8) Detergents, alcohols, solvents and other chemicals used in aircraft washing, deicing, and maintenance should be:

  flushed into the storm drainage system.

  dumped the sanitary sewage system.

  treated as chemical wastes.

  all of the above

9)Waste fuel that normally accumulates around the hydrants in an underground aircraft fueling system:

  should be allowed to percolate into the soil so as not to be a disposal problem.

  may be flushed into the storm drainage system.

  may be picked up with a petroleum absorbent material and disposed of as contaminated waste.

  should be collected and burned.

  none of the above

10)Fecal coliform bacteria, a common water pollutant, is:

  pathogenic, i.e., makes people ill.

  relatively harmless and not the subject of water standards.

  used as a measure of other fecal pollutants and likely presence of pathogenic bacteria.

  found only where free flowing untreated sewage exists.

  all of the above

11) Water pollution problem areas include:

  changes in runoff, recharging, and circulation.

  sedimentation, erosion, and construction wastes.

  sanitary wastes, aircraft activity wastes.

  storm water and other runoffs.
