Disaster Preparedness
Easy ways to eliminate contamination in water in an emergency situation.
Boiling: Boiling is the safest method of treating water.
Boiled water will better if you put oxygen back into it by
pouring the water back and forth between two clean
containers. This will also improve
the taste of stored water.
Chlorination: This method calls for the use of household
liquid bleach to kill microorganisms. Use only regular
household liquid bleach that contains 5.25 to 6.0 percent
sodium hypochlorite. Do not use scented bleaches and use
newly opened or unopened bottles of bleach. Add 16 drops
1/8 teaspoon) of bleach per gallon of water, stir, and let
stand for 30 minutes. The water should have a slight bleach
odor. If it doesn’t, then repeat the process over again and let
stand another 15 minutes.
Distillation: Distillation involves boiling water and collection
of the vapor that condenses. The condensed vapor will
be filtered of salt and most other common impurities. To
distill, fill a pot halfway with water. Tie a cup to the handle
on the pot’s lid so that the cup will hang right-side-up
when the lid is upside-down (make sure the cup is not
hanging in the water) and boil
the water for 20 minutes. The water that drips from
lid into the cup is distilled.
Filters: Many portable water filters can remove disease
causing parasites such as Cryptosporidium and Giardia.
filters that have small enough pores to filter out bacteria
or parasites. Most filters do not have the capability of
filtering out viruses.
Water sources in case of an emergency:
Inside the home: You can find water in a large number of places in your house in case of an emergency. These include water heaters, melting ice cubes, and liquid from canned fruit and vegetables.
Outside the home: Outside resources can yield potable
water as well. The best outside sources of water are
rainwater, streams, rivers, and ponds.
Essentials of managing water: People should only drink
according to their needs, drink uncontaminated water first,
do not drink carbonated drinks instead of water, and turn
off main water valves.
After a flood:
Avoid flood waters; water may be contaminated by oil,
gasoline or raw sewage. Service damaged septic tanks,
cesspools, pits and leaching systems as soon as possible.
Damaged sewer systems are serious health hazards. Listen
for news reports to learn whether or not the community’s
water supply is safe to drink. Clean and disinfect
everything that got wet. Mud left from flood waters can
contain sewage and chemicals. Ensure a supply of water
for sanitary purpose such as cleaning and flushing toilets.
Fill the bathtub and other larger containers with water.
