Mercury can travel long distances in the atmosphere—even across oceans and continents—before finally settling in lakes and rivers. This type of pollution is called non-point source pollution because the mercury ends up far away from where it was released.

Why is point pollution easier than nonpoint pollution?

Point-source pollution is easier to control than nonpoint-source pollution because it has only one source that it is coming from, so it is easier to locate it and put a stop to it. Nonpoint-source pollution is hard because it has many sources which makes it harder to put a stop to it.
