If you are planning on hiking in the Blue Ridge Mountains during the next few months, you are going to need a good amount of water. Boiling it all is probably going to be difficult.

Normal human needs are about a gallon of water a day, before you begin to think about hygenic uses. However, if you are walking through this area, carrying a load, you are going to sweat and need more water.

At the very least, I'd carry something to chemically treat water. I'd at least put some iodine in my stuff and learn how to use it.
