Water Quality Indicators

Front

What are bio-indicators?

Back

Organisms or biological responses used to assess the health of an ecosystem, particularly the presence of pollutants in water.

Front

Why are bio-indicators important for water quality assessment?

Back

They indicate the presence of pollutants and help predict the potability of water supplies.

Front

What does turbidity measure in water?

Back

The clarity of water; high turbidity indicates less clarity and potential pollution.

What is the significance of pH in water quality?

Back

pH measures the acidity or alkalinity of water; low pH can be corrosive and harmful.

What does a high level of dissolved oxygen indicate?

Back

It generally indicates good water quality and supports aquatic life.

Front

What is potability?

Back

The suitability of water for drinking; it must be free from harmful contaminants.

Front

What factors can affect water turbidity?

Back

Soil erosion, runoff, and the presence of microorganisms can increase turbidity.

Front

How does temperature affect water quality?

Back

Temperature influences dissolved oxygen levels and the metabolic rates of aquatic organisms.
