"Several days"? If the San Andreas does its thing, you're going to need more than "several days". The potential for long-term disruption of supplies is a reality. Plus, no mention of self-defense when the "takers" start looting local inner-city stores shelves and go bare. Guess where they will head? This is my Prepping scenario.
Anyone who doesn't remember the LEOs backing out of the Rodney King riots weren't paying attention, and that was just because of a verdict. Imagine the confusion and desperation if the water lines, gas lines, power lines, food distribution lines and major trucking routes are broken. Not to mention the further destruction by the rioters when Uncle Nanny can't re-supply quickly enough. It will make Katrina and Storm Sandy look like inconveniences.
Don’t you know if you store more than a ‘few’ days worth of preps you are a ‘tinfoil’ nut job? Just ask any lib and there are more than a few FReepers who will tell you the same thing.
You're forgetting the whistle.
Berkey® Systems are the world’s most powerful and economical water purification systems, providing incredibly clean, pure water in both normal and hostile environments. Berkey® systems can purify both treated water and untreated raw water from such sources as remote lakes, streams, stagnant ponds, and water supplies in foreign countries with substandard regulations.
They come in sizes large enough to meet the sustained water needs of up to 325 people per system, yet they purify without electricity or moving parts, and their portability allows them to easily be taken, and used, anywhere. Berkey® systems will operate in any location where gravity is present—and they always preserve the healthful minerals you need.
Unequalled Effectiveness: Berkey® purifiers using the Black Berkey® purification elements are proven to reduce pathogenic bacteria (including E. Coli, Klebsiella, Pseudomonas Aeruginosa, Giardia and Cryptosporidium) by 99.99999%. The Berkey Light® System has been tested with the highest pathogenic contamination levels that can be produced in a laboratory. When contamination levels exceed one billion pathogens per liter of water (10,000 times the density of contamination used in the standard test protocol for bacteriological removal) they’re classified as “TNTC” (too numerous to count.) Under normal testing protocol, one pathogenic organism is tested at a time, each with a fresh purifying element. For this test, however, the laboratory was directed to combine three separate pathogenic TNTC cultures. Tested under this extreme contamination level, absolutely no pathogens were able to make it through the purification elements. The laboratory then incubated the water, and nothing grew. When the filtered water was viewed under an electron microscope not even in-viable (dead) microbes were detectable — nothing was present but pure H2O. Furthermore, contaminants reduced to below-detectable-limits include Trihalomethanes, Radon 222, and volatile organic compounds including Benzene, 2,4-D, Heptachlor, MTBE, Styrene, Tetrachloroethylene and Toulene, among many others.
