WATER TREATMENT EXAM SCRIPT
UPDATED COMPLETE QUESTIONS AND
ANSWERS GRADED APLUS
●● Evaporation
Answer: Defined as: Water is transferred from earths surface to
atmosphere.
-80% occurs from oceans
-Evaporation occurs more at warm temperatures
●● Condensation
Answer: Defined as: Conversion of water vapor to liquid
-excess water vapor condenses to form cloud droplets
●● Transportation
Answer: Defined as: Movement of water in the atmosphere
-Also referred to as Advection
●● Precipitation
Answer: rain, hail, snow, sleet, freezing rain
-Amount varies by location & time
-Ecosystems are structured by:
,1. Precipitation
2. Temperature
●● Where is ground water found within soil?
Answer: Zone of aeration & zone of saturation
●● Groundwater
Answer: Defined as: Water that has penetrated the surface and is found
in the soil
●● Watertable
Answer: Defined as: The boundary between zone of saturation and zone
●● What are two steps during hydrologic cycle that are considered as
"pure water" processes? Why are they important?
Answer: 1. Evaporation- movement of "sea" water
2. Evaportranspiration- movement of water through plants.
They are important because they are " pure water" processes humans
rely on for fresh water.
●● Excess water usage & development around water resources result in?
Answer: 1. Decline in water quantity
, 2. Decline in water quality
●● Potable water
Answer: Defined as: Water fit for human consumption
●● Pathogen
Answer: Defined as: Disease causing organism including; viruses,
bacteria, and protozoans
●● Compare & Contrast Characteristics of Groundwater & Surface
water
Answer: Groundwater:
*Uniform quality
-Low turbidity
-low taste/odor
-low color
-low/ no dissolved oxygen
-Undesirable minerals- High Fe, Mn, CaCO3
-High hardness
Surface Water:
*Variable quality
-High turbidity
