Pet Waste: Dealing with a Real
Problem in Suburbia
Pet waste is
not the predominant or most toxic pollutant in urban streams, but it is
one of many small sources of pollution that can cumulatively have a big
impact if left unmanaged. There are thousands of dogs in the Richmond
area. Add to this figure cats and other smaller pets, and a significant
volume of waste is being generated daily.
Pet waste contains bacteria and parasites, as well as
organic matter and nutrients, notably nitrogen and phosphorous.
Some of the diseases that can be spread from pet waste
are:
-
Campylobacteriosis - a bacterial infection that causes
diarrhea in humans.
-
Salmonellosis - the most common bacterial infection
transmitted to humans from animals. Symptoms include fever, muscle
aches, headache, vomiting, and diarrhea.
-
Toxocarisis - roundworms transmitted from animals to
humans. Symptoms include vision loss, rash, fever, or
cough.
In addition to these diseases, the organic matter and
nutrients contained in pet waste can degrade water quality. When pet
waste is washed into a surface water body, the waste decays. This
process of breaking down the organic matter in the waste uses up
dissolved oxygen and releases ammonia. Low oxygen levels, increased
ammonia and warm summer water temperatures can kill fish.
Excess phosphorous and nitrogen added to surface waters
can lead to cloudy, green water from accelerated algae and weed growth.
Decay of this extra organic matter can depress oxygen levels, killing
organisms. Objectionable odors can also occur.
Flies and other pest insects can also increase when pet
waste is disposed of improperly, becoming a nuisance and adding another
vector for disease transmission.
Managing pet waste properly is something that everyone
can do to make a difference in their respective watersheds. Truly,
proper individual actions result in significant water quality
improvement when carried out by the majority. Unlike some forms of
stormwater pollutants, pet waste can be easily and economically managed
by the individual.
Sometimes, the ‘out of sight, out of mind’
attitude exists regarding pet waste. Employing this flawed thinking,
waste is often disposed of in the street stormwater catch basin. Aside
from dumping directly into a water body, this is the single worst
place to dispose of waste. In the next rainstorm, the accumulated waste
is transported quickly and efficiently to the nearby receiving water
course, polluting it. Water quality monitoring studies in Virginia and
other states have emphasized this specific problem. That said, then,
specifically what can be done?
Proper Onsite Disposal
Flush it
Pet waste itself (not the litter or bedding material)
can be flushed down the toilet. The water from the toilet goes either to
a septic system onsite or a sewage treatment
plant that removes most pollutants before the water
reaches its outlet. The used litter should be disposed of in a securely
closed bag in the trash.Bury it
You can bury the waste directly in the yard. Dig a hole
or trench that is 6 inches deep, away from vegetable gardens, play
areas, and away from any lake, stream, or well. Often, the woods is an
ideal spot. Microorganisms in the top layer of soil will break down and
digest the waste, releasing the nutrients for uptake by adjacent
vegetation. Never add the waste as a fertilizer to the garden or to the
compost pile. The disease organisms will continue to survive and create
a significant health risk.
Trash it
Check local ordinances first. Putting pet waste in the
trash is against the law in some communities. Even if legal and easy,
it’s not the best solution. Waste can contribute to the landfill
problems in the state.
Leave it to someone else
Believe it or not, a professional pet waste disposal
service exist in Richmond. This businesses will completely remove the
waste from your yard and dispose of it themselves, for a fee. See:
www.dog-gone-it.tripod.com for a list of services provided. If you
leave the waste to decay in the yard, be sure it does not become a
problem. To prevent water pollution, clean up areas near shallow wells,
storm drains, ditches, and watercourses. Always remove pet waste from
areas where children play….for obvious reasons, kids are the most
frequent victims of diseases from feces.
Ordinances, Signage and Education
Many communities have "pooper-scooper" laws that
govern pet waste cleanup. Some of these laws specifically require anyone
who walks an animal off of their property to carry a bag, shovel, or
scooper. Any waste left by the animal must be cleaned up immediately.
Call your local health officer to find out more about pet waste
regulations. In recreation areas, trails, and public parks, ‘scooper
signage’ along with plastic bag dispensers and disposal cans should
be provided. This idea is especially critical at streamside or lake
shore walking trails.
Public education is critical when addressing the
pet waste problem. Interestingly, much of the public thinks of problems
associated with pet waste as being only nuisance related-odors or
aesthetics. An actual example of this is the woman walking her dog in
the park who had brought along a brown paper bag to collect the 150
pound mastiff’s waste. This she indeed dutifully did, and then proceeded
to dispose of the bag by….tossing it into the lake!
Brochures, newsletters, signage, local public service
announcements, and evening seminars are all ways to get the word out to
the public. One very effective way to reach people is to have a flyer
enclosed in tax bills or other municipally-generated mailings that go to
all property owners.
Conclusion
The problem of pet waste disposal in suburbia is a real
one. Research has indicated strongly that water quality is negatively
impacted by this pollutant in Virginia. However, unlike many other
sources of water degradation in the state, improper pet waste management
is a dilemma that can be easily corrected through education by
organizations and common sense actions by individuals.

Environmental Protection or your local branch of Rutgers Cooperative
Extension.
