Answer 1

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

Step-by-step 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.
