Stormwater - Horses and Livestock

Horses on a farm.Horse and livestock wastes are among the many common stormwater pollutants that can degrade water quality.  Stormwater runoff from livestock waste 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 blooms and promote bacterial growth which can degrade water quality.
