Types of Nonpoint Source Polution
Pathogens are disease-causing microorganisms present in human and animal waste. This type of nonpoint source pollution can be especially dangerous. Pathogens can be bacteria, protozoa or viruses. We frequently hear of coliforms or fecal coliform that is a bacterial pathogen most commonly a result of animal waste from cattle, hogs and poultry operations, if not properly managed.
However, what many people do not realize is that another major source of fecal coliform is waste from our pets. Pathogens from pet waste can then build-up, entering our waterways in high concentrations and can lead to lesions in fish and other aquatic life, even illness in humans.
