Not at all, IMO. You probably have bleach in your home...that can take care of virtually all the beasties that might develop in previously potable, but long-stored, water. Further, as a backpacker, you probably have filters or chemical treatments you can use on water you're not confident about. Add your camp stove and fuel for boiling water and you've got multiple methods to provide clean water at home should the municipal source or the well go out...as long as you've stored water in the first place. Given the reliability of my electric co-op you can bet I've got dozens of gallons stored plus the pond, horse troughs, toilet tanks, etc.

Backpackers are extremely well set to 'rough it' at home. <img src="/forums/images/graemlins/grin.gif" alt="" />
