Fertilizers, pesticides, and organic wastes are among the many common stormwater pollutants that can degrade water quality. Stormwater runoff from botanical gardens and zoos have been found to contain high concentrations of organic wastes, fertilizers, pesticides, and soil. When these materials wash into local waters they poison fish and contaminate the water. Soil and dirt washed from the grounds can also harm aquatic life by clogging the gills of fish, blocking light transmission, lowering water temperatures, and inhibiting photosynthesis. In addition, zoos create substantial quantities of animal wastes which have 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.
