The difference between point source and nonpoint source pollution is that:

• point source pollution sources can be identified while nonpoint source pollution sources are more obscure.

• point source pollution sources can always be remedied.

• nonpoint source pollution is due to improper chemical storage.

• nonpoint source pollution is located next to the body of contaminated water.

• None of the above are correct.

True or False: Point source pollution describes pollution sources that are always located immediately next to the contaminated water, thus making them easy to identify.

Which is an example of a point source pollution source?

• a ruptured sewer pipe

• acid rain

• sediment pollution

• none of the above

What is hypoxia?
