Because of the tremendous amount of nutrients being brought into the ecosystem to export chicken worldwide, the resulting huge amount of poultry waste is spread over local pastures where it runs off into the streams and causes water pollution such as seen below. The contaminated water drains into Lake Murray and ultimately into the drinking water of Columbia residents downstream. If the poultry waste were generated by humans, when calculated by nitrogen content it equals a population of almost 400,000 more people living in Saluda County who are defecating directly onto the land, not into a sewer system. The Health Department knows this is a problem but does not know what to do about it.
