I used to do canoe trips on the English River, in western Ontario. One of the mills polluted the river with mercury, and it made the fish poisonous to eat in quantity. Throughout the lakes downstream there were signs giving the allowable eating -- on the order of one trout per week. We could drink the water. Local indians at the Grassy Narrows reserve ...

I have traveled the back country for 4-6 weeks a year for 30 years, mostly in the Canadian rockies and on the pre-cambrian shield. I've never used water purification, nor did we generally in our group. We've had some cases of the runs over the years, but the spread out nature made it unlikely it was a water source that did it. Far more likely bad hygiene ...

I'm going to assume that you are employing the SODIS method of water sterilization. To sum up the details of the process, this method is where you fill plastic pop bottles, (PET), up with rather clear water 3/4 full, shake them up, and let them sit in the bright sun for 5+ hours. The mechanism this works by is by utilizing the UV radiation in sunlight. ...

A filter like that will will be good for 50 gallons even if it's used over two years. You'll want to make sure you dry it properly between uses, and some filters have boiling instructions (esp. those with clay ceramics) when they haven't be used for an extended period of time.

At the very least, you'll want some type of plastic bottle. You can cut the end off of your plastic bottle and layer in ground ( smashed ) charcoal from your camp fire along with cotton, sand, grass, most anything you can get your hands on to filter out the different sized particles. Charcoal being the most likely to weed out micro organisms. ...

For certain contaminants such as Giardia, it doesn't matter whether the water is running fast or slow. You will get infected regardless. So this idea about "fast water" is a myth that is not correct. If you are drinking close to the source of streams and there is not any mining activity or industrial pollution nearby, then OF COURSE you are drinking clean ...
