Unit 2 Water Quality Review

Front

What is the pH range that indicates a basic solution?

Back

A pH above 7 indicates a basic solution.

Front

What are the harmful effects of channelization in water bodies?

Back

Channelization prevents water from spreading into floodplains, increases water temperature, and increases turbidity.

Front

What is the preferred pH range for most aquatic organisms?

Back

The preferred pH range for most aquatic organisms is between 6 and 8.

Front

What is a point source of water pollution?

Back

A point source of water pollution is a single identifiable source, such as oil refineries.

Front

What is the healthiest combination of water quality parameters?

Back

Low temperature, neutral pH, and low nitrates is the healthiest combination.

Front

Define turbidity in water quality context.

Back

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

Front

What is nitrification?

Back

Nitrification is the biological oxidation of ammonia to nitrite followed by the oxidation of nitrite to nitrate.

Front

How does temperature affect dissolved oxygen levels in water?

Back

Higher temperatures generally decrease the solubility of oxygen in water.

Front

What is the significance of maintaining a neutral pH in aquatic ecosystems?

Back

Maintaining a neutral pH is crucial for the health of aquatic organisms, as extreme pH levels can be harmful.

Front

What are non-point sources of water pollution?

Back

Non-point sources of water pollution are diffuse sources that cannot be traced to a single point, such as agricultural runoff.
