Explanation: Flocculation involves adding chemicals to clump together suspended particles, making them easier to remove in subsequent sedimentation steps.
2. Question: Which of the following is a common method for measuring water quality in terms of pH?
A. Turbidity meter
B. pH meter
C. Conductivity probe
D. Spectrophotometer
Answer: B
Explanation: A pH meter directly measures the acidity or alkalinity of water, which is crucial for assessing its suitability for various uses.
3. Question: What is the main purpose of a water distribution network?
A. To store water underground
B. To treat wastewater
C. To deliver treated water to consumers
D. To collect rainwater
Answer: C
Explanation: Water distribution networks use pipes and pumps to transport treated water from treatment plants to homes, businesses, and industries.
4. Question: Which technology is primarily used for desalination of seawater?
A. Reverse osmosis
B. Boiling and condensation
C. Ion exchange
D. Activated carbon filtration
Answer: A
Explanation: Reverse osmosis applies pressure to force water through a semi-permeable membrane, removing salts and impurities, making it suitable for drinking.
5. Question: What does BOD stand for in the context of water pollution?
A. Biological Oxygen Demand
B. Biochemical Organic Decay
C. Base Oxygen Level
D. Biotic Oxidation Demand
Answer: A
Explanation: BOD measures the amount of oxygen microorganisms consume while decomposing organic matter in water, indicating pollution levels.
6. Question: Which regulation in the US governs the quality of drinking water?
A. Clean Air Act
B. Safe Drinking Water Act
C. Clean Water Act
D. Environmental Protection Act
Answer: B
Explanation: The Safe Drinking Water Act sets national standards for drinking water quality and requires regular monitoring by public water systems.
7. Question: What is the role of chlorine in water treatment?
A. To soften hard water
B. To disinfect and kill pathogens
C. To remove odors
D. To increase pH levels
Answer: B
Explanation: Chlorine is added as a disinfectant to eliminate bacteria, viruses, and other microorganisms that could cause waterborne diseases.
8. Question: Which of the following is a renewable source of water?
A. Fossil aquifers
B. River systems
C. Glacial ice reserves
D. Deep groundwater
Answer: B
Explanation: River systems are replenished by rainfall and runoff, making them a renewable source, unlike non-renewable sources like fossil aquifers.
9. Question: What is the primary cause of eutrophication in water bodies?
A. Overfishing
B. Nutrient pollution from fertilizers
C. Oil spills
D. Acid rain
Answer: B
Explanation: Excess nutrients like nitrogen and phosphorus from fertilizers lead to algal blooms, depleting oxygen and harming aquatic life.
10. Question: In wastewater treatment, what is the function of secondary treatment?
A. Removing large solids
B. Disinfecting the water
C. Breaking down organic matter biologically
D. Adding chemicals for pH adjustment
Answer: C
Explanation: Secondary treatment uses biological processes, such as activated sludge, to decompose organic pollutants before further treatment.
11. Question: Which material is commonly used for water pipes in modern distribution systems?
A. Lead
B. PVC (Polyvinyl Chloride)
C. Copper
D. Asbestos
Answer: B
Explanation: PVC is durable, corrosion-resistant, and cost-effective, making it a standard choice for water pipes to ensure safe delivery.
12. Question: What is the impact of groundwater over-extraction?
A. Increased surface water levels
B. Land subsidence and saltwater intrusion
C. Improved soil fertility
D. Reduced evaporation
Answer: B
Explanation: Over-extraction lowers the water table, leading to land sinking and intrusion of saltwater into freshwater aquifers.
13. Question: Which process is used to remove hardness from water?
A. Distillation
B. Ion exchange
C. Sedimentation
