Water Treatment Plant Operator Chapter
2 fully solved graded A+ 2023
Why has it become necessary to conserve and properly budget our water resources? - correct answer
Drought conditions have forced water supply managers to recognize the need to conserve and properly
budget our water resources. Increasing costs of energy make it expensive to pump water from deeper
groundwater levels or to trans port water over long distances.
How are water shortages and energy consumption linked together? - correct answer Energy
consumption and water shortages are linked together because: (1) with falling groundwater levels,
energy is required ot pump from deeper levels; and (2) water prjects that use large amounts of
electricity to pump water over long distances are requiring water users to pay increased water rates to
cover higher energy costs.
Name three ways groundwater may become contaminated? - correct answer Groundwater becomes
contaminated from: (1) sea-water intrusion, (2) seepage from septic tank leaching systems and
agricultural drainage systems, (3) surface runoff into poorly constructed wells, and (4) seepage from
improper disposal of hazardous wastes.
What is the water (hydrologic) cycle? - correct answer The water (hydrologic) cycle is the cycle or path
water follows from evaporation from oceans, to formation of clouds, to precipitation, to runoff, to
evaporation and transpiration back to the atmosphere, and eventually back to the ocean.
List the three basic types of water rights. - correct answer 1. Riparian 2. Appropriative 3. Prescriptive
What are the general water quality characteristics of surface water supplies? - correct answer In general,
surface water supplies are characterized by soft water, suspended solids, turbidity, some color and
microbial contamination.
What are the general water quality characteristics of groundwater supplies? - correct answer In general,
ground water supplies are characterized by higher concentrations of dissolved solids, dissolved gases,
low color, relativly high hardness, and freedom from microbial contamination.
