WATER TREATMENT EXAM COMPLETE
QUESTIONS AND 100% VERIFIED
ANSWERS
\Q\.What are the main steps during the Hydrologic cycle? - ANSWER-✔1. Evaporation
2. Condensation
3. Transportation
4. Transpiration
5. Precipitation
6. Runoff
\Q\.Evaporation - ANSWER-✔Defined as: Water is transferred from earths surface to
atmosphere.
-80% occurs from oceans
-Evaporation occurs more at warm temperatures
\Q\.Condensation - ANSWER-✔Defined as: Conversion of water vapor to liquid
-excess water vapor condenses to form cloud droplets
\Q\.Transportation - ANSWER-✔Defined as: Movement of water in the atmosphere
-Also referred to as Advection
,\Q\.Precipitation - ANSWER-✔rain, hail, snow, sleet, freezing rain
-Amount varies by location & time
-Ecosystems are structured by:
1. Precipitation
2. Temperature
\Q\.Where is ground water found within soil? - ANSWER-✔Zone of aeration & zone of saturation
\Q\.Groundwater - ANSWER-✔Defined as: Water that has penetrated the surface and is found
in the soil
\Q\.Watertable - ANSWER-✔Defined as: The boundary between zone of saturation and zone
\Q\.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.
\Q\.Excess water usage & development around water resources result in? - ANSWER-✔1.
Decline in water quantity
2. Decline in water quality
\Q\.Potable water - ANSWER-✔Defined as: Water fit for human consumption
\Q\.Pathogen - ANSWER-✔Defined as: Disease causing organism including; viruses, bacteria,
and protozoans
, \Q\.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
-colored
-Dissolved Oxygen
-Low hardness
-Taste & odor
\Q\.What are the objectives of public drinking water treatment - ANSWER-✔1. Provide potable
water for safe human consumption
2. To provide aesthetically acceptable water
- Turbidity
- Color
- Taste
-Odors
