The city of Elmhurst was having problems with people dumping pollutants into their local water supply. To help with this problem, the mayor sent out pamphlets in 2016 that explained the dangers of water pollutants in our watersheds and how to safely dispose of common household waste materials. The graph below shows the changes in the number of pollution incidences before and after the pamphlets were mailed. What conclusions can you make based on this evidence?

• The pamphlets had no effect on the amount of pollution dumped into the river.

• The pamphlets caused people to dump more pollution into the river.

• The pamphlets caused people to dump less pollution into the river.

• The pamphlets did not include information about watersheds.

Runoff from agricultural land carries chemicals and fertilizers that collect in a lake. The buildup of chemicals can eventually cause -

• aquatic life, such as fish and turtles, to die from a lack of oxygen.

• excess water to fill the aquifer, resulting in pore shrinkage and subsidence.

• river tributaries to reroute, changing the flow of natural waterways.

• rainfall levels to drop causing drought and a shorter growing season.
