Water Quality Review

Front

What is the pH scale?

Back

The pH scale measures how acidic or basic a solution is, ranging from 0 (very acidic) to 14 (very basic), with 7 being neutral.

Front

What pH value is considered toxic to aquatic organisms?

Back

A pH value of 5 is considered toxic to aquatic organisms.

Front

How does acid rain affect water bodies?

Back

Acid rain decreases the pH of streams and lakes, making them more acidic.

Front

What does high turbidity in water indicate?

Back

High turbidity often indicates a high number of contaminants in the water.

Front

Why is pH important for aquatic life?

Back

Variations in pH can indicate the presence of toxic substances, affecting the health of aquatic organisms.

Front

What happens to fish when dissolved oxygen is low and temperature is high?

Back

Large numbers of fish are likely to die under these conditions due to stress and inability to breathe.

Front

What is turbidity?

Back

Turbidity is the cloudiness or haziness of a fluid caused by large numbers of individual particles.

Front

What is the ideal pH range for most freshwater organisms?

Back

The ideal pH range for most freshwater organisms is between 6.5 and 8.5.

Front

What can cause a sudden drop in dissolved oxygen levels in water?

Back

Factors like algal blooms, decomposition of organic matter, and temperature increases can cause a sudden drop in dissolved oxygen.

Front

What is the effect of temperature on dissolved oxygen levels?

Back

As temperature increases, the solubility of oxygen in water decreases, leading to lower dissolved oxygen levels.
