With so many people tied to 'the grid' what if this most valuable resource is tainted or worse yet not available for hours, days, weeks, months or in the case of Flint Michigan YEARS!! It's over 3 years now since Flint Michigan crisis and they are still without safe, clean drinking water and dependent on aid.
Protect yourself and help to remove your dependence should something of a similar nature happen in your area by learning how to filter/purify and make safe drinking water.
