What is eutrophication?

Back

Eutrophication is the process by which a body of water becomes overly enriched with nutrients, leading to excessive growth of algae and depletion of oxygen.

Front

What factors best determine the health of a lake used for drinking water?

Back

The health of a lake used for drinking water is best determined by its temperature and dissolved oxygen levels.

Front

What are indicators of healthy water systems?

Back

Indicators of healthy water systems include low temperatures, high dissolved oxygen, and neutral pH.

Front

How does excessive rainfall affect the turbidity of a river?

Back

Excessive rainfall increases the turbidity of the river downstream due to runoff carrying sediments and pollutants.

Front

What is point source pollution?

Back

Point source pollution refers to contaminants that enter a water body from a single, identifiable source, such as a pipe or drain.

Front

What is nonpoint source pollution?

Back

Nonpoint source pollution is pollution that comes from multiple, diffuse sources, making it harder to identify and control.

Front

What is turbidity?

Back

Turbidity is a measure of how clear water is, often affected by the presence of suspended particles.

Front

What role do dissolved oxygen levels play in aquatic ecosystems?

Back

Dissolved oxygen levels are crucial for the survival of aquatic organisms; low levels can lead to dead zones.

Front

What is the significance of pH in water quality?

Back

pH affects the solubility and biological availability of nutrients and metals in water, influencing aquatic life.

Front

How can nutrient runoff affect freshwater systems?

Back

Nutrient runoff can lead to eutrophication, causing algal blooms that deplete oxygen and harm aquatic life.
