Making Water Safe in an Emergency cdc.gov/healthywater/emergency/drinking/making-water-safe.html If you don't have safe bottled water and if boiling is not possible, you often can make small quantities of filtered and settled water safer to drink by using a chemical disinfectant such as unscented household chlorine bleach. Disinfectants can kill most harmful or disease-causing viruses and bacteria, but are not as effective in controlling more resistant organisms, such as the parasites Cryptosporidium and Giardia.(https://www.cdc.gov/parasites/giardia/index.html) Chlorine dioxide tablets can be effective against Cryptosporidium if the manufacturer s instructions are followed correctly. To disinfect water with unscented household liquid chlorine bleach: If the water is cloudy, 1. Filter it through a clean cloth, paper towel, or coffee filter OR allow it to settle. 2. Draw off the clear water. 3. Follow the instructions for disinfecting drinking water that are written on the label of the bleach. 4. If the necessary instructions are not given, check the "Active Ingredient" part of the label to find the sodium hypochlorite percentage, and use the information in the following table as a guide. Typically, unscented household liquid chlorine bleach will be 8.25% sodium hypochlorite, though concentrations can be different. Using the table below, add the appropriate amount of bleach using a medicine dropper, teaspoon, or metric measure (milliliters). 5. Stir the mixture well. 6. Let it stand for at least 30 minutes before you use it. 7. Store the disinfected water in clean, sanitized containers(https://www.cdc.gov/healthywater/emergency/drinking/cleaning-preparing-storagecontainers.html) with tight covers. If the water is clear, 1.

EMERGENCY DISINFECTION OF DRINKING WATER In an emergency situation where regular water service has been interrupted like a hurricane, flood, or water pipe breakage local authorities may recommend using only bottled water, boiled water, or disinfected water until regular water service is restored. The instructions below show you how to boil and disinfect water to kill most disease-causing microorganisms that may be present in the water. However, boiling or disinfection will not destroy other contaminants, such as heavy metals, salts, and most other chemicals. ONLY USE WATER THAT HAS BEEN PROPERLY DISINFECTED FOR DRINKING, COOKING, MAKING ANY PREPARED DRINK, WASHING DISHES, AND FOR BRUSHING TEETH. Use bottled water or water you have properly prepared and stored as an emergency water supply. Boil water, if you do not have bottled water. Boiling is sufficient to kill pathogenic bacteria, viruses and protozoa (WHO, 2015). If water is cloudy, let it settle and filter it through a clean cloth, paper towel, or coffee filter. Bring water to a rolling boil for at least one minute. At altitudes above 5,000 feet (1,000 meters), boil water for three minutes. Let water cool naturally and store it in clean containers with covers. To improve the flat taste of boiled water, add one pinch of salt to each quart or liter of water, or pour the water from one clean container to another several times. Disinfect water using household bleach, if you can t boil water. Only use regular, unscented chlorine bleach products that are suitable for disinfection and sanitation as indicated on the label. Do not use scented, color safe, or bleaches with added cleaners. If water is cloudy, let it settle and filter it through a clean cloth, paper towel, or coffee filter. Locate a clean dropper from your medicine cabinet or emergency supply kit. Locate a fresh liquid chlorine bleach or liquid chlorine bleach that is stored at room temperatures for less than one year. The label should say that it contains 8.25% of sodium hypochlorite. Use the table on the next page as a guide to decide should add to the water, for example, add 6 drops of bleach to each gallon of water. Double the amount of bleach if the water is cloudy, colored, or very cold. Stir and let stand for 30 minutes. The water should have a slight chlorine odor. If it doesn t, repeat the dosage and let stand for another 15 minutes before use. If the chlorine taste is too strong, pour the water from one clean container to another and let it stand for a few hours before use.
Table 1: Bleach to Water Dose Guidance Amount of Liquid Bleach Volume of Water to Add 1 quart/liter 2 drops 1 gallon 6 drops 2 gallons 12 drops (1/8 teaspoon) 4 gallons 1/4 teaspoon 8 gallons 1/2 teaspoon Bleach contains 8.25% sodium hypochlorite. ADDITIONAL WATER GUIDANCE FOR EMERGENCIES Prepare and store an emergency water supply. Visit the Federal Emergency Management Agency (FEMA) website www.ready.gov/managing-water for additional guidance on preparing and storing an emergency water supply. Look for other sources of water in and around your home. Although bottled water is your best choice, you may be able to find other sources of water by melting ice cubes or draining your hot water tank or pipes. You should not use water from toilet flush tanks or bowls, radiators, waterbeds, swimming pools, or spas. You can also use river or lake water. It is generally better to use flowing water than still, stagnant water. However, do not use water with floating material in it or water that has a dark color or questionable odor. Regardless of the source, treat the water by following the instructions on the previous page. If you have a well on your property that has been flooded, make sure to disinfect and test the well water after the flood. Contact your state or local health department for advice or go to water.epa.gov/drink/info/well/whatdo.cfm. Consider how the water looks and how to filter it if needed. Disinfection does not work as well when water is cloudy or colored. If water is cloudy, let it settle. Then filter the water through a clean cloth, paper towel, or coffee filter. Store the settled and filtered water in clean containers with covers. OTHER DISINFECTION METHODS If you don t have liquid bleach, you can use one of the other disinfection methods described below. Granular calcium hypochlorite. The first step is to make a chlorine solution that you will use to disinfect your water. For your safety, do it in a ventilated area and wear eye protection. Add one heaping teaspoon (approximately ¼ ounce) of high-test granular calcium hypochlorite (HTH) to two gallons of water and stir until the particles have dissolved. The mixture will produce a chlorine solution of approximately 500 milligrams per liter. To disinfect water, add one part of the chlorine solution to each 100 parts of water you are treating. This is about the same as adding 1 pint (16 ounces) of the chlorine solution to 12.5 gallons of water. If the chlorine taste is too strong, pour the water from one clean container to another and let it stand for a few hours before use. CAUTION: HTH is a very powerful oxidant. Follow the instructions on the label for safe handling and storage of this chemical. Common household iodine (or tincture of iodine ). You may have iodine in your medicine cabinet or first aid kit. Add five drops of 2% tincture of iodine to each quart or liter of water that you are disinfecting. If the water is cloudy or colored, add 10 drops of iodine. Stir and let the water stand for at least 30 minutes before use. Water disinfection tablets. You can disinfect water with tablets that contain chlorine, iodine, chlorine dioxide, or other disinfecting agents. These tablets are available online or at pharmacies and sporting goods stores. Follow the instructions on the product label as each product may have a different strength. MORE INFORMATION World Health Organization (WHO), 2015. Technical Briefing on Boil Water.

Water ready.gov/water Storing Water in Plastic Soda Bottles It is recommended you purchase food grade water storage containers from surplus or camping supplies stores to use for water storage. Before filling with water, thoroughly clean the containers with dishwashing soap and water and rinse completely so there is no residual soap. If you chose to use your own storage containers, choose two-liter plastic soft drink bottles not plastic jugs or cardboard containers that have had milk or fruit juice in them. Milk protein and fruit sugars cannot be adequately removed from these containers and provide an environment for bacterial growth when water is stored in them. Cardboard containers also leak easily and are not designed for long-term storage of liquids. Also, do not use glass containers, because they can break and are heavy. Follow these steps for storing water in plastic soda bottles. Thoroughly clean the bottles with dishwashing soap and water, and rinse completely so there is no residual soap. Sanitize the bottles by adding a solution of 1 teaspoon of non-scented liquid household chlorine bleach to a quart of water. Mix the sanitizing solution in the bottle so that it touches all surfaces. After sanitizing the bottle, thoroughly rinse out the sanitizing solution with clean water. Fill the bottle to the top with regular tap water. If the tap water has been commercially treated from a water utility with chlorine, you do not need to add anything else to the water to keep it clean. If the water you are using comes from a well or water source that is not treated with chlorine, add two drops of non-scented liquid household chlorine bleach to the water. Let the water stand for 30 minutes before using. A slight chlorine odor should be noticeable in the water, if not, add another dose of bleach and allow the water to stand another 15 minutes. Tightly close the container using the original cap. Be careful not to contaminate the cap by touching the inside of it with your finger. Place a date on the outside of the container so you can know when you filled it. Store in cool, dark place. Water can also be treated with water purification tablets that can be purchased at most sporting goods stores. Water that has not been commercially bottled should be replaced every six months. More information on water treatment is available at RedCross.org. 1/1
