Fertilizers, pesticides, and organic wastes are among the many common stormwater pollutants that can degrade water quality. Stormwater runoff from nursery and greenhouse operations has been found to contain high concentrations of organic wastes, fertilizers, pesticides, and soil that can leave your property. 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.
