Stormwater - Pets and Pet Waste

Pet friends - cat and dog.Pet wastes are among the many common stormwater pollutants that can degrade water quality.  When water (i.e. rain, hose water, sprinklers, etc.) contacts pet wastes the resulting stormwater runoff 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.  As pet wastes decompose, they demand a high level of oxygen from water.  This demand can kill fish and plant life by reducing the amount oxygen available to them.
