Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.

2. The process of adding air to water. Air can be added to water by either passing air through water or passing water through air. In wastewater treatment - air is added to freshen wastewater and to keep solids in suspension. With mixtures of wastewater






3. A coordinating agency formed in 1961 for state boards that administer licensing exams and maintain records for landscape architects to practice.






4. Installation of pumps to lift wastewater to a higher elevation in places where flat land would require excessively deep sewer trenches. Also used to raise wastewater from areas too low to drain into available collection lines. These stations may be e






5. The movement or dislocation of underground soil or structure. Earth shift is usually caused by external forces such as surface loads - slides - stresses or nearby construction - water movements or seismic forces.






6. An arrangement of pipes - equipment - devices - tanks and structures for treating wastewater and industrial wastes. A water pollution control plant.






7. The oxidation ditch is a modified form of the activated sludge process. The ditch consists of two channels placed side by side and connected at the ends to produce one continuous loop of wastewater flow and a brush rotator assembly placed across the






8. OE The pressure at a specific elevation exerted by a body of water at rest - or _ In the case of groundwater - the pressure at a specific elevation due to the weight of water at higher levels in the same zone of saturation.






9. The legal grant of right-of-use to an area of designated private property.






10. This landscape architecture specialization has evolved to encompass maintenance of a site in its present condition; conservation of a site as part of a larger area of historic importance; restoration of a site to a given date or quality; renovation o

17. Any method of determining the weight a compacted material is able to support without damage or displacement. Usually stated in pounds per square foot.






18. Most plumbing codes require a vent pipe connection of adequate size and located downstream of a trap in a building wastewater system. This vent prevents the accumulation of gases or odors and is usually piped through the roof and out of doors.






19. A water treatment process in which solid particles settle out of the water being treated in a large clarifier or sedimentation basin.






20. In the United States - a certification of individuals entitled to use the term 'landscape architect' or to practice landscape architecture or both - by means of examination and required degree and experience criteria.

22. The lowest point of the channel inside a pipe - conduit - or canal.






23. A capped opening in a building lateral -usually located on the property line - through which the pipelines can be cleaned.






24. Sewers are surcharged when the supply of water to be carried is greater than the capacity of the pipes to carry the flow. The surface of the wastewater in manholes rises above the top of the sewer pipe - and the sewer is under pressure or a head - ra






25. The elevation of the invert (or bottom) of a pipeline - canal - culvert - or similar conduit. _ The inclination or slope of a pipeline - conduit - stream channel - or natural ground surface; usually expressed in terms of the ratio or percentage of nu






26. A biological wastewater treatment process which speeds up the decomposition of wastes in the wastewater being treated. Activated sludge is added to wastewater and the mixture (mixed liquor) is aerated and agitated. After some time in the aeration tan






27. A system used where wastewater collection systems and treatment plants are not available. The system is a settling tank in which settled sludge is in intimate contact with the wastewater flowing through the tank and the organic solids are decomposed






28. A sewer that receives wastewater from many tributary branches or sewers and serves a large territory and contributing population.






29. Federal agency responsible for producing and managing many federally-funded public service programs - especially those affecting housing and public spaces.






30. A tank used to store a chemical solution of known concentration for feed to a chemical feeder. A day tank usually stores sufficient chemical solution to properly treat the water being treated for at least one day. Also called an AGE TANK.






31. Water that does not contain objectionable pollution - contamination - minerals - or infective agents and is considered satisfactory for drinking.






32. A line from which heights and depths are calculated or measured. Also called a datum plane or a datum level.






33. The condition of water or soil which contains a sufficient amount of acid substances to lower the pH below 7.0.






34. Opening in a sewer provided for the purpose of permitting operators or equipment to enter or leave a sewer. Sometimes called an 'access hole' or a 'maintenance hole.'






35. A groundwater table that has seasonal changes in depth or elevation.






36. The force that resists the separation of two bodies in contact.






37. Sedimentation basin overflow weir. A plate with Vnotches along the top to ensure a uniform flow rate and avoid shortcircuiting.






38. A small tank (usually covered) or a storage facility used to store water for a home or farm. Often used to store rainwater.






39. A popular social concern of the late nineteenth and early 20th centuries aimed at improving the appearance of urban areas through better planning and the addition of formal - romanticized public spaces and gardens.
