Poop, Pathogens and the Future of Free Flowing Waters

by Jan Weaver

My mother bought me a copy of "How to S**t in the Wood"" by Kathleen Meyer for my birthday.Ê It took me a while to settle down with the book because I figured I knew everything I needed to know about the topic already.Ê After all, how hard could it be?Ê Well, as it turns out, the difficult part isn't doing it, but doing it in a way that does not pollute the water. MeyerÕs book could be retitled How to S**t in the Woods Responsibly.

Ê The average human produces about a quarter of a pound of feces each day.Ê The state of Wisconsin has over 1.4 million camper days per year in its state parks.Ê Multiplied by 50 states, that comes to 70 million camper days per year.Ê Double it to account for campers in national parks and then divide by 4 and you get 35 million pounds of poop each year deposited in the less refined facilties typically provided by your average camp site.

Ê Since feces are not simply the undigested remainder of our bran flakes, but also the repository of all sorts of intestinal microbes we carry around with us, we have been innoculating the wilderness with dozens of human microbes, some of them lethal.Ê Prior to the 1970's it was quite common to assume headwaters and springs were reliable sources of safe drinking water. No more. The pathogenic protozoans Cryptosporidium parvum and Giardia lamblia are now widespread in U.S. surface waters and even in springs influenced by surface waters (if a spring is directly recharged by rainfall, there may not be enough time for the cysts of the protozoa to die).

These pathogens have two stages, an active growing stage that lives in the intestine and a cyst stage that is shed in the feces and which can persist for months under the right conditions. Furthermore, both can be found in animals, both domestic and wild.Ê This means that careless pooping in nature can lead to the rapid spread ofÊ Giardia or Cryptosporidium in animal populations.Ê Once established in beavers or muskrats or rabbits or dozens of other animals, they can persist in an area indefinitely, even without infected humans.

Both protozoans can cause diarrhea, cramps, nausea, vomiting, headache and low-grade fever within a few to 10 days of infection.Ê This may clear up or may settle into a chronic or relapsing condition resulting in severe debiliation and weight loss. For children, the elderly or immune compromised individuals there is even the possiblity of death.Ê Some people can carry Giardia and Cryptosporidium without exhibiting any symptoms.Ê So even symptom-free persons can contaminate water supplies.

And it is not just campers and backpackers that have to worry about filtering their water either.Ê In Milwaukee in 1993, a Cryptosporidium contamination of the city water system sickened 400,000 people and killed 100. Many if not most public water systems have had to upgrade their treatment protocols specifically to handle Cryptosporidium, which is resistant to chlorine.Ê This has placed a very expensive burden on small rural water supplies which now require special filtration systems.

Campers may have been responsible for the initial spread of these pathogens in nature, but unregulated treatment of animal waste from confined animal feeding operations (CAFOs) may pose a much larger threat in the future.Ê Hogs and other livestock can also carry Girardia, Cryptosporidium and a host of other infectious pathogens that they shed in their feces, and some operations can produce as much sewage as Kansas City.Ê In order to reduce the spread of pathogens, K.C.'s sewage is required to undergo settling, aerobic digestion and anaerobic digestion before the remaining sludge can be land applied. The manure from a CAFO, on the other hand, is simply stored in lagoons until it is sprayed on nearby fields.Ê Depending on environmental conditions, the pathogens may or may not be killed before the next rainfall carries them into the nearest watercourse and from there into a local water supply.

If the popularity of backpacking did contribute to the spread of human pathogens in the wild, it was an unintended consequence, one which Meyer and the outdoor travel industry are now trying to address by teaching backpackers how to dispose of their wastes responsibly.Ê Maybe it's time for a similar book on How to S**t in a CAFO.Ê More fundamental than the right to use oneÕs property as one wishes, is the responsibility not to impair someone elseÕs use and enjoyment of their property. Waste is waste and knowing what we know now about Giardia and Cryptosporidium, we wonÕt be able to plead ignorance if the free-flowing waters that belong to all of us become not just undrinkable, but unsafe even for swimming or wading because of the burden of pathogens contributed by untreated animal waste.

Answer to BioRegional Quiz: Answer to Bio Regional Quiz: Ê Missouri marketed 8.3 million hogs in 1998, up from 5.1 million in 1988.Ê In 1988 there were 17,000 hog operations, in 1998 there were 5000.Ê The human population of Missouri is around 5.6 million, and we produce 511 million pounds of poop each year. Hogs produce about four times as much poop per individual or over 3 billion pounds of poop a year. This is around 6 times as much poop as the human population in Missouri and almost 10 times as much poop as is generated by campers in the entire U.S. http://www.dnr.state.mo.us/magazine/2000_spring/one_last_word.htm
