I usually use AquaMira drops for my water treatment and on every trip I have ever taken they have worked out great. We are planning a trip to the Grand Canyon next year and I am concerned that the drops will not be such a great idea. There is very limited water there and often times the water source is a very shallow, soot filled puddle. It may be difficult to even get a jug into the water source without wasting the precious resource and then it may end up filled with stuff in the water. So I thought about purchasing a filter for the trip and my first instinct was to go with one of the sawyer squeeze models, but I think they still presents the same problem. Would I be better off with a standard filter type setup where I just need to get the intake below the water surface and then can pump the water out? Any suggestions? We will be off the main trails for 3 days so water is a concern for the trip and I just want to be prepared. Thanks.
