Tannic Water

I want to do some backpacking in Florida, but I know that the water in the Everglades and most streams is high in tannins. Is it safe to drink after filtration or purification pills?

Answer:

I have never heard of any known risks to human health from drinking water with tannins, which results from water passing through organic matter. But, yes, it is important to disinfect the water thoroughly to kill pathogens.  —Buck

    I live in Florida and I’ve encountered these situations several times. If you are lucky, after filtering, the water just tastes a bit like unsweetened tea, not too bad. Too much tannins can get super bitter, though. Charleston, SC had a problem after hurricane Hugo in 1989, the drinking water there is obtained from the Edisto river, which experienced a huge spike in tannins from all the downed foliage. Our water tasted bitter for weeks.
