Question 1
A chicken farmer stores all of the chicken manure from his farm in large piles next to the river. Throughout the spring and summer, the piles of manure are exposed to rain and wind. The farmer finally removes the manure in the fall. What two types of pollution are demonstrated in this real world example?
Nutrient
Bacterial
Question 2
Instead of riding his bike, a college student drives to class every day. He also drives to the store, to friends' houses, and everywhere else. Every time he fills up his tank, a little bit of gasoline drips to the ground. The car's exhaust contains nitrogen oxides, which contribute to nitrogen levels in nearby water bodies. What two types of pollution are demonstrated in this real world example?
Toxic
Nutrient
Question 3
By rotating their crops, farmers can reduce their dependence on fertilizers, herbicides, and pesticides. Despite the benefits of crop rotation, many farmers only grow one or two crops year after year. This increases their use of fertilizers, herbicides, and pesticides. What two types of pollution are demonstrated in this real world example?
Toxic
Nutrient
Question 4
A new mall and movie theater are being built on the outskirts of Suburbia. Trees and brush are cleared away, the land is bulldozed, and a silt fence is installed across part of the development. However, construction is delayed for a year, leaving the land exposed to the elements. What type of pollution is demonstrated in this real world example?
Sediment
Question 5

Bacterial
Question 6
After buying a new house by the lake, the Harrison's decided to cut down the trees and bushes that were blocking their view. This left an open area with no vegetation between the house and the lake. What type of pollution is demonstrated in this real world example?

What two types of pollution are demonstrated in this real world example?
Nutrient
Bacterial
