What are the characteristics of a healthy riparian area, and how can this improve water quality?
Why You Should Care
The 1972 Clean Water Act (CWA) set the rules and regulations about water pollution and the standards for cleaning up after pollutant releases. Part of the CWA sets the fines for pollution above regulated standards, but the more important component is the creation of best management practices (BMP) to minimize water pollution in the future.
Some BMPs deal with the creation of riparian areas that filter nutrient or sewage runoff before it enters streams or rivers. These areas function as forest buffers or wetlands, where the producers soak up and use the nutrients. Here, the diversity and function of natural ecosystem services solve the pollution problem before it can cause eutrophication in the water.
Other BMPs seek to encourage farmers or industrial sources to change their practices to save money, increase efficiency, or just minimize waste generation. These changes are all voluntary, so there has to be popular support or nothing will change unless pollution rises above the standards.

Giving up such a large area along the creek is a bigger loss of potential crop or lawn than it would be for larger landholders. For example, a 100-acre square parcel would only lose 4 acres to the riparian buffer (assuming the rest of the parcel was flat and not adjacent to the stream).
