Question

9/22 water pollution and the flint water crisis
according to the video, what is the best definition of non - point source pollution?
○ chemicals and debris that is washed into lakes/rivers/streams by precipitation and runoff
○ chemicals and debris that is dumped into lakes/river/streams

Explanation:

Non - point source pollution is characterized by pollutants that enter water bodies via diffuse means like precipitation and runoff, rather than from a single, identifiable source. The first option describes this correctly as chemicals and debris washed into lakes/rivers/streams by precipitation and runoff. Dumping is a point - source activity.

Answer:

The best definition is "Chemicals and debris that is washed into lakes/rivers/streams by precipitation and runoff".
