Watershed Pollutants

Even though the Chesapeake Bay is mainly located into Virginia, why can other states play a role in polluting it?

• Water in New Jersey pollutes the Atlantic Ocean

• Because the Chesapeake Bay Watershed is located in 6 different states.

• Other states send their trash to Virginia

• The river starts in New York

A student’s model of an area near a city depicts many activities that affect the quality of the water in the area. How does the agricultural activity most likely affect the surface water of the area?

• Crops absorb pure water from soil, causing the remaining water to contain more salt.

• Crops reduce erosion, increasing the amount of soil entering the river.

• Excess crop fertilizer is carried by runoff into the river, causing excess growth of water plants.

• Excess crop material accumulates on the riverbanks, slowing the movement of the river water

A student sets up the investigation shown below. The movement of colored water through the gravel best models —

• condensation of water vapor

• conservation of water

• surface runoff of precipitation

• pollution of groundwater

When runoff crosses the land, it picks up fertilizers that have been used on crops and lawns. These contaminants will eventually enter a lake, river or stream, which may lead to -

• the earth’s surface to sink.

• the water in an aquifer to drop.

• harmful rapid growth of algae.

• cleaner water for drinking and bathing.

The proposed law will protect the lake because plant roots between the wetland and the lake will stop pollution from entering the lake.

• The proposed law will protect the lake because plant roots between the wetland and the lake will stop pollution from entering the lake.

• The proposed law will not protect the lake because animals that live in or near the lake will add pollution to the lake.

• The proposed law will not protect the lake because groundwater will carry pollution from the wetland directly into the lake

• The proposed law will protect the lake because the high elevation of the water table will block pollution from entering the lake.
