Equine wastes are among the many common stormwater pollutants that can degrade water quality. Stormwater runoff from horse wastes has been found to contain high concentrations of pathogens such as bacteria, parasites, and viruses. When they wash into our recreational waters they can make people sick with sore throats, intestinal problems, rashes, nausea, and eye and ear infections. Manure also contains nutrients such as phosphorus and nitrogen, that fertilize aquatic algae which can degrade water quality.
