The Environmental Protection Agency (EPA) classifies pet waste as a dangerous pollutant in the same category as toxic chemicals and oil.

The EPA warns that pet waste is a major contributor of Nonpoint Source Pollution and the runoff from pet waste will continue to produce harmful effects on our drinking water supply, recreation, fisheries and wildlife.

The U.S. Center for Disease Control and Prevention (CDC) warns that pet waste can spread parasites including hookworms, roundworms, ringworms, tapeworms and Salmonella. When infected dog poop comes into contact with your lawn, the poop will eventually "disappear", but the parasite eggs will remain in the soil for years.

Roundworm larvae will cause blindness. When a human contacts a roundworm larva, it can migrate through the body causing disease to the brain, lungs, kidneys, liver, heart and eyes.

When any human or animal comes into contact with that soil through everyday activities such as walking barefoot, gardening or children playing, they risk infection from those eggs, even years after the poop is gone.

Dog poop is loaded with E. Coli and other harmful bacteria including fecal coliform bacteria, which causes serious kidney disorders, intestinal illness, cramps, diarrhea and even death in humans.

In just a couple of days, 100 dogs can deposit enough bacteria to temporarily close a bay, and all watershed areas within 20 miles of it, to swimming and fishing.

Just one day’s waste from one large dog can contain 7.8 billion fecal coliform bacteria, enough to contaminate 15 acres of shellfish beds making them unsafe to eat.
