Reducing storm runoff and erosion

Explanation:

Surface waters are those that do not infiltrate towards the subsoil, but accumulate on the surface of the land, causing rivers, oceans, lagoasm tiachos, among others. In other words, we can say that these waters represent the most used water reservoirs for human activities.

Even with its remarkable importance for the maintenance of life, surface waters receive a lot of pollution, and it is necessary that governments value the preservation of these waters, so that these sources are always available. In this regard, we can say that an efficient way for the American government to control water pollution would be to reduce runoff and storm erosion.
