Which of the following has resulted in deterioration in water quality?

Correct option is A

Ans. (a) Not disposing of waste water properly

Improper disposal of wastewater has led to the deterioration of water quality. Pollutants from untreated sewage, industrial effluents, and agricultural runoff contaminate water bodies, making them unsuitable for consumption and harming aquatic life.

Key points:
● Wastewater contains pollutants like chemicals, pathogens, and nutrients that degrade water quality.
● Improper disposal leads to waterborne diseases like cholera and typhoid.
● Agricultural runoff adds excessive nutrients, causing eutrophication and harming aquatic ecosystems.
● Industrial effluents often contain toxic substances, leading to bioaccumulation.
● Addressing water pollution requires treatment plants, proper regulations, and public awareness.
● Clean water is essential for health, biodiversity, and economic activities.

Additional Information:

• Deforestation affects soil erosion 
• Wrong distribution of water resources leads to scarcity
• Excess population increases water demand
