We All live in a watershed
No matter where you are right now, you are in a watershed. A watershed is an area of land that drains to a common point such as a creek, stream, river, or lake. We often refer to watersheds interchangeably as ‘basins.’ Our homes, schools, grocery stores, shopping malls, soccer fields, baseball diamonds, where we grow our food, and where we play all exist in watersheds.
Because all of the water drains to one common point, everything that we do on the land within a watershed can impact our shared water resources. Water can become contaminated when unwanted materials, or pollutants, end up in the water.
There are two types of water pollution: point source pollution and nonpoint source pollution. Point source pollution can be traced back to its original source, or point, where the polluting substance directly enters the waterway, for instance, a factory discharge pipe releasing chemicals into a river. Nonpoint source pollution happens when rainfall/snowmelt water runs across the land or through the ground, picking up pollutants along the way, and they are deposited into downstream water bodies. Nonpoint source pollutants include sediment, nutrients, pesticides, bacteria, oil, grease, and more.
