All living things must have water to survive, whether they get it from a water fountain, a rain cloud, or any other source. Without water, your body would stop working properly. Water makes up more than half of our body weight. We couldn’t survive for more than a few days without it.
Public water systems, also referred to as “City Water”, provide drinking water to approximately 85% of the US population. Many of us take safe and plentiful drinking water for granted. Providing safe drinking water is a partnership that involves the EPA, the State, local authorities and the water system operator.

When a public water supply is not available, homes and businesses have to rely on their own private drinking water supplies. Examples of these supplies are wells, cisterns, springs and ponds. They are not subject to EPA standards, although most state and local governments do set rules to protect users of these wells. Unlike public drinking water systems serving many people, they do not have experts regularly checking the water’s source and its quality before it is sent to the tap. These households must take special precautions to ensure the protection and maintenance of their drinking water supplies.

This information is provided for the use of the individual householder when the treatment and distribution facilities of a public or private water system cannot be operated on a normal basis, when a water supply has become flooded, when an extended power failure renders a water system inoperable, or when the bacterial quality of available water is suspect. The methods described in this leaflet will not remove or reduce toxic, chemical or radiological contaminants and water exposed to such contamination should not be used.
If the available water contains any suspended material or is cloudy, the water is to be strained through several layers of clean cloth or the water allowed to settle and the clearer water drawn off into a clean covered container. Boil the water vigorously at or near 212F (100C) for one full minute to kill any disease causing bacteria that may be present in the water. A microwave oven may be used to boil the water. The flat taste of boiled water may be improved by pouring it back and forth between two clean containers before use.
When boiling is not practical, common household laundry bleach usually contains a chlorine compound that can disinfect water.Check the label on the bottle to make sure it indicates the solution is 5.25% sodium hypochlorite with no additional active ingredients. If the water contains any suspended material or is cloudy, strain the water through several layers of clean cloth or allow material to settle and draw off the clearer water. If an unopened bottle of bleach is available, use the new bottle to add the appropriate following number of drops to disinfect the water. If you do not have a dropper, use a clean utensil such as a knife to dip into the bleach and let the drops fall into the water as you count them (16 drops are approximately equal to 1/8 of a teaspoon).

Mix thoroughly by stirring or shaking and let stand for at least 30 minutes. A slight chlorine odor should be detectable in the treated water. If it is not, repeat the chlorine dose and let stand for an additional 20 minutes before use. The taste of the treated water may be improved by pouring it back and forth between two clean containers or by allowing it to stand for a few hours before use.
A tincture of iodine from a home medicine chest, a first aid kit, or the local pharmacy may be used to disinfect water. If the water contains any suspended material or is cloudy, strain the water through several layers of clean cloth or allow to settle and draw off the clearer water into a clean container. Add the appropriate following number of drops of iodine to disinfect the water.
