I agree. I don't consider water purification an issue as far as EDC in a strictly urban environment and certainly not where I live. My EDC is not an EOTWAWKI kit. Even when we had a serious water quality issue in parts of the valley last year, bottled water was easily had. Heck, we rarely drink untreated tap water here at all because it tastes so bad in most places. I always start any drives anywhere with two 3/4 or more full bottles of cold water inside the car and there's 3 gallons in the trunk. That's there primarily in case of an incident on the freeways which can result in being stuck for an hour or two at most or a breakdown. And, again, I see that as more for others than myself since I rarely go anywhere without a 1/2 tank of gas or more and I can idle for hours with the AC on at 110 degrees with no problems on that. If I break down in the urban environment, "rescue" is no more than a hour away and you'd be hard pressed to find anyplace in the area more than a few blocks from a convenience or grocery store and someplace airconditioned with water to wait is likely an even shorter walk away. Step or drive out of the urban environment or put yourself in a very different atypical situation and everything changes.
