Waterborne hiking illness: that's a mouthful, any way you swallow it.
There are certain things you must never do as a hiker.
On this short list: Swallow contaminated water.
However, as a hiker you know that you need to consume lots of hiking water. Hydration is the key to a great hike.
Which means you need to know all about backpacking water purification methods.
You're in the right place!
A bunch of little nasties with charming names such as Giardia, Cryptosporidium, and Blastocystis.
Oh, if only it were as simple as reading a sign, sort of like a warning sign on the highway.
You need to rely on common sense and technology to keep yourself away from waterborne hiking illness.
And every once in awhile, Mother Nature WILL leave you a sign (if you're paying attention).
Let's briefly review hiking common sense.
Avoid stagnant surface water as a drinking source. Even if you filter this water, it will put more stress on your apparatus, clogging it up and potentially cutting down on its effectiveness.
And it means you'll have to clean your filter more often.
Boiling stagnant water for at least 5 minutes will probably work, but the gunk floating around in it is pretty hard to swallow - visually, at least.
And boiled water tastes flat.
Here's a tip from Mother Nature:
Don't drink from surface water with lots of traffic (i.e. footprints, broken branches, obvious signs of disturbance) around it.
Speaking of holes...
If you're using surface water as a swimming hole, don't swallow the water.
Even if only a few people per season use a "pristine" mountain lake, you could be asking for trouble if you don't treat the water before ingesting it.
When I first started backpacking in the 1970's, there were two options for ensuring clean drinking water: boil it, or treat it with iodine.
The first option resulted in flat tasting water and a depleted fuel bottle, while the second option was nearly undrinkable.
I'm glad things have come a long way since then!
Nowadays, I carry a water filter.
And I'm intrigued by the Steripens marketed at my favorite gear store.
But remember, technology is only as smart as your brain.
If you don't use it properly, or blindly believe in it despite evidence to the contrary, things can go very bad.
Take time before your hiking trip to use the technology, and know how to repair or clean it out on the trail.
And having a back-up plan for water purification isn't a bad idea, either.
How would you know if you picked up a waterborne hiking illness?
Giardiasis, caused by Giardia intestinalis (lamblia), is widespread in United States surface waters.
Giardia is also called "beaver fever" to indicate that wild animals can be reservoirs of infection. Their feces makes its way into potential drinking water for hikers.
Read up on
giardiasis, so you can avoid this waterborne hiking illness. Or know how to treat giardia in yourself or a hiking buddy if your water treatment methods fail.
Also be able to recognize the full spectrum of giardia symptoms.
Another waterborne hiking illness you want to avoid is called cryptosporidiosis. This is also caused by a microscopic culprit, and can make a hiker miserable in the same way we outlined above.
Viruses are too small to be handled effectively except by boiling the water for at least 5 minutes (something that takes a long time, and a lot of fuel, at higher elevations).
Or by a really efficient (and expensive) water filter, like this one: the MSR Guardian Purifier.
Lots to think about in terms of protecting yourself against waterborne hiking illness, that's for sure.
Here's general information about how to make drinking water safe for consumption.
Use it as a starting point for planning how to keep your drinking water from becoming a source of misery.
