Unfortunately various forms of pollution‚ including runoff and erosion‚ can interfere with the health of the watershed. Therefore it is important to protect the quality of our watershed.

These may be collected by rainwater runoff and carried into steams‚ rivers‚ lakes‚ and even into the ocean. More than 14 million Americans drink water contaminated by with pesticides.

With every spray and use of the pesticides and human-made chemicals‚ persistent as they are‚ the resulting effects spread throughout ecosystems. Bioaccumulation occurs through the levels of the food chain(biological magnification)‚ microorganisms and fish are exposed to the chemicals that render the water polluted‚ fish are eaten by birds and other aquatic life
