San Diego.
The city spent roughly $10,000 on extra trash cans, nagging signs and plastic "mutt mitts" at its Dog Beach, where the surf was closed to swimmers 125 times in 2000. The measures led to "measurably fewer dog piles. That's the term we use," says Ted Medina, deputy director for coastal parks. He estimates the beach is 30%-40% cleaner than it was before the effort started late last year.

Bacteria levels in the river exceed standards so often that a Web site tells would-be boaters and swimmers whether the river is safe on any given day. To help clean it up, park officials recently started giving tickets to visitors who have dogs but no doggie bags.

Boulder, Colo.
Here the problem wasn't dirty water but the nitrogen in dog droppings. Native grasses in the city's mountain parks are used to low-nitrogen conditions. But with dogs doing their business, weeds were muscling aside the grasses. The city did 10 months of education before starting to hand out $100 fines last year. Boulder officials had to convince residents that dog waste "is not fertilizer," says Mike Patton, co-director of open space and mountain parks. "Some people really did believe it was."

 

HOW MUCH DOG WASTE IS PRODUCE IN ONE YEAR IN THE UNITED STATES?
4.4 billion pounds of dog waste is produced every year in the United States alone! This is equal to 900 football fields, one foot high. This is a hidden health issue that no one wants to "touch" as approximately 71,542,900 registered dogs in the United States produce more than 29,000 tons of waste daily. There are 48,143,849 dog owners in the United States.

EPA Clean Water Act of 1998 has deemed that animal waste or feces as secondary storm runoff contaminate.

Many communities are implementing pet waste management programs by hiring a professional canine waste  management service, making available pet waste management products, posting signs in parks or other pet frequented areas, sending mailings,  and making public service announcements.

Many communities have "pooper-scooper" laws that govern pet waste cleanup.

MYTH:
Dog feces safely disintegrates into the soil.

FACT:
-Dog feces left on your lawn can pose a serious health hazard!
-It can take up to 1 year for dog feces to break down.
-Dog feces is protein based and is poisonous to lawns.
-Dog waste poses threat to water

 

Dog waste poses threat to water
By Traci Watson, USA TODAY

Cities struggle with 'dog piles' Where they're cracking down:
For as long as the dog has been man's best friend, dog waste has posed a menace to man's nose and foot. Now science has revealed a more unsavory truth: It's an environmental pollutant.

In the mid-1990s, scientists perfected methods for tracking the origin of nasty bacteria in streams and seawater. From Clearwater, Fla., to Arlington, Va., to Boise the trail has led straight to the hunched-up dog — and to owners who don't pick up after their pets.

At some beaches, dogs help raise bacteria levels so high that visitors must stay out of the water. Goaded by such studies, some cities have directed as much as $10,000 in the last few years to encourage dog owners to clean up after their pets. A few municipalities have started issuing citations to those who ignore pet clean-up ordinances.

Many dog lovers are in denial about their pooches' leavings. But researchers have named the idea that areas used by dogs pump more bacteria into waterways — the "Fido hypothesis."

Dogs are only one of many fixtures of suburban America that add to water pollution. Lawn fertilizers, rinse water from driveways and motor oil commonly end up in streams and lakes.

But unlike those sources, dogs generate disease-causing bacteria that can make people sick. Studies done in the last few years put dogs third or fourth on the list of contributors to bacteria in contaminated waters. "Dogs are one of our usual suspects," says Valerie Harwood, a microbiologist at the University of South Florida. "At certain sites, we find their effect to be significant."

It doesn't take a Ph.D. to figure out that dog do is nasty. But it took science to determine how nasty it is.

From mutt to blue-blooded champion, all dogs harbor so-called coliform bacteria, which live in the gut. The group includes E. coli, a bacterium that can cause disease, and fecal coliform bacteria, which spread through feces. Dogs also carry salmonella and giardia. Environmental officials use measurements of some of these bacteria as barometers of how much fecal matter has contaminated a body of water.

This wouldn't matter if pet dogs were as rare as pet chinchillas. But four in 10 U.S. households include at least one dog, according to the American Pet Products Manufacturers Association. The association's statistics also show that Americans owned 54.6 million dogs in 1996 and 68 million dogs in 2000. Of that total, 45% were "large" dogs — 40 pounds or more.

Those numbers add up to a lot of kibble. That wouldn't matter if all dog owners also owned a pooper-scooper. But several studies have found that roughly 40% of Americans don't pick up their dogs' feces (women are more likely to do so than men).

New analysis provides answers.
The environmental impact of dog waste went unrecognized for decades. Then scientists developed lab techniques to determine the origin of fecal bacteria contaminating water. One method is a variant of DNA fingerprinting. Another method looks at the antibiotic resistance of microbes from different species.

Scientists caution that the methods are still new.
They are able to distinguish between major and minor sources of pollution, but they can't say with precision whether dogs contribute 20% or 30% of the pollution in a stream. "There's inherently some error," says Don Stoeckel, a microbiologist for the Ohio district of the U.S. Geological Survey who's studying bacteria-tracking methods. "I think the best (they) can do is give you some evidence of the magnitude of each source."

Nonetheless, Stoeckel says, the analytical tools do provide useful information. Researchers have studied dozens of waterways. Wild birds and humans usually head the roster of who's fouling the water. But in some areas, dogs make significant deposits.

At Morro Bay, Calif., for example, dogs contribute roughly 10% of the E. coli, says Christopher Kitts, a microbiologist at California Polytechnic State University-San Luis Obispo. "And that can be the difference between a beach closing and a beach not closing," he says.

Places where dogs dirty the water:
• Stevenson Creek in Clearwater, Fla. Residents were worried that a sewage treatment plant contaminated the creek. But when Harwood tested the water, she found that dogs, along with leaky septic tanks and wild animals, were to blame for high bacteria counts. Dog feces probably washed out of yards by the creek, Harwood says.
• Four Mile Run in Arlington and Fairfax counties, Va. Studies show that dogs add to the contamination in this suburban Washington, D.C. stream. Officials calculate that the 12,000 dogs living in Four Mile Run's watershed leave behind more than 5,000 pounds of "solid waste" every day.
• Boise River in Boise. The river suffers from high bacteria levels that make it unsuitable for swimming. Testing of streams and drainpipes flowing into the river showed that in urban areas, dogs were a leading culprit. In some spots, dogs and cats account for even more of the bacteria than human feces — from dysfunctional septic tanks and leaky sewage pipes — do.

Fines don't sway some. Even where dogs aren't the prime offenders, they're one of the few polluters authorities have control over. At many California beaches, for example, seagulls and other birds are most responsible for high bacteria levels. But federal laws protect birds.

That leaves dogs. Officials know that they have a lot of educating to do before people realize their pooch can be a canine sewage pipe. Some people find it humiliating to carry a plastic bag.

A survey by the Center for Watershed Protection in 1999 found that of the 41% of respondents who rarely or never clean up after their dogs, 44% would refuse to do so in the face of fines and neighbors' complaints. Reasons included, "because it eventually goes away," "small dog, small waste," and "just because."

So more cities may follow the lead of Laguna Beach, Calif., a wealthy beach enclave. The city provides pooper-scoopers at the local dog park. But many people "don't take care of their little friends," says Victor Hillstead, the city's parks and buildings manager.
