When pet waste is improperly disposed of in the street catch basins, it can be picked up by stormwater runoff and washed into nearby waterbodies. Animal feces often end up in lakes and streams, causing significant water pollution.
Decaying pet waste consumes oxygen and sometimes releases ammonia. Low oxygen levels and ammonia can damage the health of fish and other aquatic life. Pet waste carries bacteria, viruses, and parasites that can threaten the health of humans and wildlife. Pet waste also contains nutrients that promote weed and algae growth (eutrophication). Cloudy and green, Eutrophic water makes swimming and recreation unappealing or even unhealthy.
As a dog owner, you can help prevent contamination of local waterways and parklands from dog waste by picking up after your dog.
