Water Quality Review

Front

What is turbidity?

Back

Turbidity is a measure of how clear water is, affected by the presence of suspended particles like sediment and debris.

Front

What is the average pH of pure water?

Back

The average pH of pure water is 7, which is considered neutral.

Front

Why are nitrates important for plants?

Back

Nitrates are essential nutrients that help plants grow by providing the necessary nitrogen for their development.

What are macroinvertebrates?

Back

Macroinvertebrates are organisms without a backbone, such as insects and worms, that are used as bioindicators to assess stream health.

Front

What is dissolved oxygen?

Back

Dissolved oxygen is the amount of oxygen that is present in water, crucial for the survival of aquatic organisms.

Front

What factors can affect the pH of water?

Back

Factors that can affect the pH of water include pollution, runoff from land, and natural processes like respiration and photosynthesis.

Front

What is the role of sediment in water quality?

Back

Excess sediment can reduce water clarity (turbidity), harm aquatic habitats, and carry pollutants.

Front

What is a bioindicator?

Back

A bioindicator is a species or group of species used to assess the health of an ecosystem, often sensitive to environmental changes.

Front

How does temperature influence dissolved oxygen levels?

Back

Warmer water holds less dissolved oxygen than cooler water, affecting the survival of aquatic life.
