Answer 1

Answer:

One example of how a water system is contaminated by non-point source pollution is Several inches of acid rain fall over a lake.

Explanation:

Examples of non-point source pollution are mostly associated to rainfall or even snow melt. All the other alternatives in this question are examples of point source pollution. They all come from direct sources. The rainfall, however, is a diffuse form of pollution since it is spread throughout the lake.
