Ch 14 Water Pollution

Which of the following is NOT true regarding the Chesapeake Bay?

• It is one of many small estuaries along the east coast of the United States.

Which is an example of a nonpoint source of water pollution?

• Waste overflow from a water treatment plant due to excessive rains

• Mercury emissions from coal burning power plants

• Runoff from sprayed agricultural fields

• Garbage dumped at an abandoned landfill

• Acid drainage from an abandoned mine

What is the difference between a point source and a nonpoint source of water pollution?

• A nonpoint source is easily identifiable.

• Point sources can be targeted for reduction.

• Nonpoint sources tend to be factory outputs.

• Point sources tend to be agricultural.

• Nonpoint sources are less harmful to the environment

Which is a type of wastewater?

I. Sewage water from toilets

II. Water from showering and bathing

III. Water from washing clothes

• I only

• II only

• III only

• I and II

• I, II, and III

Human wastewater entering into bodies of water such as rivers or lakes can be dangerous because

I. it causes a drop in the biological oxygen demand.

II. it can lead to cultural eutrophication.

III. the wastewater can carry pathogens.

• I only

• II only

• III only

• II and III

• I, II, and III

Which is a phenomenon in which a body of water becomes rich in nutrients?

• Fishery collapse

• Nutrient runoff

• Wastewater

• Dead zones

• Eutrophication

Cultural eutrophication is the result of

• nutrient loss in a waterway.

• nutrient loss in a floodplain

• bacteria increase in a waterway

• nutrient inputs from human activities.

• nutrient input from a storm event.
