Water Quality Indicators

Front

What is dissolved oxygen?

Back

Dissolved oxygen is the amount of oxygen that is present in water, which is essential for the survival of aquatic animals like fish.

Front

What does pH measure in water?

Back

pH measures how acidic or basic the water is, with a scale ranging from 0 (very acidic) to 14 (very basic). Healthy water typically has a pH between 6.5 and 8.5.

Front

What is salinity?

Back

Salinity is a measure of the amount of dissolved salts in water, which can affect the health of aquatic ecosystems.

Front

What are bio-indicators?

Back

Bio-indicators are living organisms, such as certain species of fish or insects, that can provide information about the health of an ecosystem.

Front

What is the significance of high dissolved oxygen levels in water?

Back

High dissolved oxygen levels indicate a healthy water system, supporting diverse aquatic life.

Front

What temperature range is considered healthy for aquatic life?

Back

Cooler temperatures are generally healthier for aquatic life, as high temperatures can reduce dissolved oxygen levels.

Front

What are nitrates and why are they important?

Back

Nitrates are compounds that contain nitrogen and are important nutrients for plants, but high levels can lead to water pollution and algal blooms.

Front

What is the ideal pH range for healthy water?

Back

The ideal pH range for healthy water is between 6.5 and 8.5.

Front

How can heavy rainfall affect water quality?

Back

Heavy rainfall can lead to runoff that carries pollutants into water bodies, potentially lowering dissolved oxygen levels and increasing nitrates.

Front

What are chemical factors in water quality?

Back

Chemical factors include dissolved oxygen, pH, nitrates, and salinity, which are used to assess the quality of water.
