• It is released into a nearby creek or river.

• It is pumped underground into aquifers.

• It is bottled and sold in stores.

• It is pumped directly back to local homes, schools, and businesses

Students designed an experiment to study where water drains after the sprinkler system is used to maintain the football field.  They attached a container that added red dye to the water before it sprayed onto the field.  Students placed water collection containers in many places near the field.

Which location could the students place a water collection container to determine the effect of runoff from the football field?

• In the ground near the sprinkler

• In a gutter that flows to a nearby pond

• Directly under the sprinkler

• Suspended directly above the sprinkler

Landfills are a way to manage trash by burying the trash underground.  Modern landfills have a bottom layer of thick clay covered with a plastic liner.  On top of the plastic liner, the landfill has pipes with holes that flow to collection tanks.

If a landfill lacked the clay, plastic, and pipes, how would the environment most likely be affected?

• Rainwater would not absorb into the ground below the landfill.

• Animals would be more attracted to the landfill due to odor.

• Groundwater near the landfill would be polluted.

• Garbage in the landfill would not be compacted.

Using the image provided, which answer choice correctly summarizes how the pollution from the factory and the commercial fishing industry are connected?

• The factories provide nutrients for the fish, increasing their populations, which in turn helps the fishing industry by increasing their profits. 

• The factories produce pollution, which ends up in the water, reducing the number of animals in the oceans. The fishing industry then cannot catch enough fish to meet the demand. 

• The fishing boats produce pollution, which impacts the factory’s ability to produce its product.

• The fishing boats catch the majority of fish in the oceans, which prevents the factories from having the required materials to function.

Neighborhoods in coastal areas use algaecide in their ponds to control algae growth. The algaecide interferes with the algae's ability to conduct photosynthesis which kills the algae, allowing the pond to look clean. When there is a large rainstorm, the algaecide runs off into the local area streams. This water eventually runs out into the ocean. What is the likely outcome of the algaecide getting into the oceanic ecosystem?

• Increase in the size of the fish

• Increase in the number of zooplankton

• Plants will increase in size

• Plants will decrease in number
