Can I preserve water for emergency use by canning it? How long can I keep it?
Although it would be possible to
can water for emergencies, it is a waste of energy and
canning jars. It is not necessary to heat treat water to
be stored for emergencies. Water reserves can be stored
in thoroughly washed, clean containers with
tight-fitting lids such as plastic milk jugs. Clean
water stored in clean containers with tight-fitting lids
will remain palatable for an indefinite period. Check
containers periodically for leaks or cloudiness. If the
water starts to look, taste or smell bad, change it. If
you have any doubts about the safety of the water to be
stored, purify it before storage by boiling or chemical
