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

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.
