Water Quality Flashcard 1

Front

What is eutrophication?

Back

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

Front

What are the consequences of eutrophication?

Back

The end result of eutrophication includes decreased oxygen levels in the water, which can lead to fish kills.

Front

What does high turbidity in water indicate?

Back

High turbidity indicates that the water is murky or cloudy, often due to suspended particles, which can harm aquatic life.

Front

How can you identify a healthy lake?

Back

A healthy lake is indicated by a high number of biodiversity indicators, such as various species of plants and animals.

Front

What causes an algae bloom in water systems?

Back

Algae blooms are most likely caused by large amounts of nitrates from agricultural runoff entering the water.

Front

Who is responsible for ensuring the safety of drinking water in the United States?

Back

The Environmental Protection Agency (EPA) is responsible for ensuring the safety of drinking water.

Front

What is the role of the EPA?

Back

The EPA regulates water quality standards and monitors pollutants to protect public health and the environment.

Front

What are nitrates and why are they important in water quality?

Back

Nitrates are compounds that can promote plant growth; however, excessive nitrates in water can lead to eutrophication.

Front

What is the significance of dissolved oxygen in water?

Back

Dissolved oxygen is crucial for the survival of aquatic organisms; low levels can lead to fish kills.

Front

What is turbidity and how is it measured?

Back

Turbidity is a measure of how clear water is, often measured in NTU (Nephelometric Turbidity Units).
