Question 1:

What is water quality monitoring?

Explanation: Water quality monitoring involves assessing the chemical, physical, and biological characteristics of water to determine its suitability for various uses and to detect any pollution or contamination.

Question 2:

Which of the following is a commonly measured parameter in water quality monitoring?

Explanation: Dissolved oxygen is a commonly measured parameter in water quality monitoring. It indicates the amount of oxygen dissolved in water and is crucial for supporting aquatic life.

Question 3:

What is the acceptable pH range for most freshwater ecosystems?

Explanation: The acceptable pH range for most freshwater ecosystems is pH 6-8. pH values outside this range can have adverse effects on aquatic organisms and indicate water pollution.

Question 4:

Which of the following is a common indicator of water pollution?

Explanation: High turbidity is a common indicator of water pollution. It refers to the cloudiness or haziness of water caused by suspended particles, which can be an indication of pollution or sedimentation.

Question 5:

Which of the following methods is used for collecting water samples in water quality monitoring?

Explanation: Grab sampling is a common method used for collecting water samples in water quality monitoring. It involves directly collecting a representative sample of water from a specific location for laboratory analysis.
