Question

the primary difference between point source and nonpoint source pollution is: nonpoint source pollution is due to improper chemical storage while point source pollution is related to agricultural runoff. none of these answer choices are correct. nonpoint source pollution is located next to the body of contaminated water while point source pollution can be harder to locate. point source pollution sources cannot be identified. point source pollution sources can be readily identified while nonpoint source pollution sources are often unclear.

Explanation:

Point - source pollution comes from a distinct and identifiable source like a factory pipe. Non - point source pollution, such as runoff from fields during rain, has diffuse origins and is harder to pinpoint.

Answer:

point source pollution sources can be readily identified while nonpoint source pollution sources are often unclear.
