Water Purification :: Washington State Dept. of Health
The treatments described below work only to remove bacteria or viruses from water. If you suspect the water is unsafe because of chemicals, oils, poisonous substances, sewage or other contaminants, do not drink the water. Don’t drink water that is dark colored, has an odor or contains solid materials.
Storing water safely
– The best source of drinking water during an emergency is water you have stored with your
emergency supplies.
– Store one gallon of water per person per day–enough for at least three days.
– Store-bought, factory-sealed bottled water is best. Check for an expiration date and
replace as needed.
If you choose to fill your own water containers:
-Collect the water from a safe supply.
-Store water in thoroughly washed plastic containers such as soft drink bottles. You can also purchase food-grade plastic buckets or drums.
-Seal water containers tightly, label with date, and store in a cool, dark place.
-Replace water every six months.
-Never reuse a container that held toxic substances such as pesticides, chemicals
or oil.
