Human Impact on Watershed

Overflow during a heavy rainstorm from a wastewater treatment plant would result in –

• polluted runoff into nearby ponds.

• flooding in the local aquifer.

• weakened housing foundations.

• over-treated drinking water.

The movement of colored water through the gravel best models —

• surface runoff of precipitation

• conservation of water

• pollution of groundwater

When fertilizers enter surface water, they cause problems in 
the watershed by -

• increasing the amount of nutrients available to fish in lakes and streams.

• 
  clogging narrow streams and preventing water from flowing properly.

• raising the water level in nearby rivers to levels leading to flooding.

• causing rapid algal growth that decrease oxygen levels and choke aquatic life.

Pollutants from a highway enter a stream or creek and travel to a river. River water tested with the pollutant found is called  

• point source pollution
  Available space for crops

• nonpoint source pollution.

• eutrophic pollution

• riparian pollution

If gasoline or oil or trash goes into a storm drain in the street, it goes directly...

• to the sewage treatment plant

• into the stream

• to groundwater

• none of the above

A student's model of an area new 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?

• 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

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

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

A student drew the model to represent a part of a watershed and some human activities that affect the watershed. How do the industrial, agricultural, and residential activities of humans most likely affect the groundwater in the area?

• The activities prevent most of the water from evaporating into the atmosphere

• Pollutants from the activities percolate through the soil and enter the water table

• The activities replace the groundwater used.

• All of the above

The following computer model was created to illustrate how a watershed can be affected by human activities. What is the most likely reason for placing the farm land upstream from the factories?

• The water at the highest point of the river will have been impacted the least by human activities, so it should be the cleanest.

• Farms do not have a negative impact on watersheds, so they should be placed upstream.

• The factory puts pollution into the air, so it does not matter where the farm is located.

• The farm should be placed upstream because pesticides from the farm will end up in the river, which is beneficial for the factories downstream.

The model shows an area near a lake. Community leaders are planning new laws to help protect the lake from pollution. One proposed law will make it illegal to dump trash on the shore of the lake, but the law still allows trash to be placed in the area labeled "Flow-through" wetland." Which statement about the proposed law is supported by the model?

• 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 new 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.
