>>181609Complete horse shit. Not all pesticides are the same. Boiling will reduce boscalid, azoxystrobin is significantly reduced by UV radiation, chlorpropham is not found in any significant quantities that would deter any outdoorsman. Don't even get me started on degradation.
Are you drinking out of the Great Lakes? Filter away if you're dumb enough to consume the water.
What about alachlor, lindane, endothall? Hmm. AOP is really the best option, far better than filters or boiling. UV is still pretty effective on most.
But that brings us to the main point: EPA findings. If you don't research your areas EPA findings prior to a trip, specifically the water information, you're a special kind of idiot. No amount of filter or fire is going completely eliminate either (but do you want to start arguing volubility at that point?).
Filters are useless because what one can control it lacks elsewhere. Adsorption and all that jazz. Or do you run with an activated carbon filter capable of catching it all?
The fact remains you should do research first and abandon any plans if the water findings are scary (and they very rarely are, aside from the Great Lakes). Aside from that, you'd have to ingest a lot of water long term to have any adverse effects. Lindane poisoning, for example, is commonly reported to affect farmers using it longterm, not backwoods campers. Alachlor is only above the MCL in 15 states.
So no, get out of here with your bullshit. You don't magically develop cancer because you swallow some water with the aforementioned chemicals. You have to drink a lot of it and long term.
