Very sad. Water is #1. Not just water, but safe water. Three days and your dead. Sadly, a water softener was not a wake-up call for these people. So many are complacent and missing the required synapses between their neurons. Zombies is correct.

Correct. Water is #1. The best way to insure an uncontaminated water source for you is to buy property where an artesian well is present. Even in the case of drifting radiation or chemical contamination, an artesian well should remain pure. Have a pump built to access it and then make certain you have a backup that doesn't require electricity to run. Then have a backup to that. Then all that remains is shelter, food and self defense. Zombies like pure water too, ya know.
