Study by city of San Francisco has shown that dog poop occupies 3.4% of residential landfills.
Storm water carries dog poop and other dog waste directly into waterways. Pet waste is responsible for up to 90% of all bacterial watershed pollutionin urban areas of the U.S.
Dog poop has a lot of nitrogen and adding nitrogen to our water depletes the oxygen needed for fish and wildlife.

E. coli, Giardia, Salmonella live inside dog poop and are dangerous to babies, humans and other animals when they enter our water system.
Roundworms and hookworms are also common in dog poop. These parasites are dangerous too when we contact them in soil.
