Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The city wants to terminate one of the sewage treatment plants in an effort to save money. the EPA recommends to monitor the water before making a decision. One way to monitor water quality is to periodically determine the dissolved oxygen levels. What predictions can be made that will support or deter the city’s decision?
A
Determining the potential increase in treated sewage will predict the increase dissolved oxygen levels in the water. This will result in increase in the fish population which will increase local tourism.
B
Monitoring water quality before determines the load restrictions the environment can handle. An increase in the output raises the risk in decrease dissolved oxygen levels which will result in an increase in dead fish.
C
Dissolved oxygen is not a standard water quality measurement therefore knowing the amounts is not relative to the city’s decision. The Environmental Protection Agency is wasting time and money creating baseline data.
D
Determining water quality at both locations will determine the chlorination required for the sewage. Excess chlorination will increase dissolved oxygen levels, stimulating fish spawns. This will support the city’s decision to terminate the plant.
Explanation: 

Detailed explanation-1: -Fence flushing methods can reduce the generation of sewage. Through reasonable planning and management of poultry breeding scale, reduce water pollutants. Use “dry manure” and other technologies to separate manure from wastewater. Use wastewater separation equipment to separate sewage and livestock and poultry urine.

Detailed explanation-2: -Primary treatment removes material that will either float or readily settle out by gravity. It includes the physical processes of screening, comminution, grit removal, and sedimentation.

Detailed explanation-3: -Shut off faucets when not in use. Repair leaking faucets or pipes. Take shorter showers. Install low flow devices on faucets and showerheads and install low flow/dual flush toilets. Replace older dishwashers and washing machines with newer, more energy efficient and water conserving models. More items
