After a major storm, or disaster you have to assume that all water sources have been contaminated, until you have been informed otherwise. After a disaster, you should only used bottled water or purify all water for drinking, cooking, brushing your teeth, and for cooking, eating, and washing utensils. You should also use purified water for washing your kitchen, body and handsbathroom and kitchen surfaces.
The two common disease-causing microorganisms often found in floodwaters are Giardia lamblia and Cryptosporidium. These microorganisms are often found in rivers and lakes.
1. Giardia can causefatigue and diarrhea, and cramps after ingestion.
2. Cryptosporidium can cause nausea, diarrhea and or stomach cramps. Individuals with weakened immune systems, such as the very old and very young and Individuals with weakened immune systems, such as children and the elderly are likely to have more more and severe persistent symptoms.
When disinfecting or purifying water, do not use dark color water, or water that has an odor, or contains floating material.
One method of disinfecting water is to boil it for 10 minutes at a rolling boil. Water that has been boiled usually has a flat taste. To improve the taste, you can aerate the water by pouring it back and forth from one clean container to another, and then allow the water to stand for a several hours. You can also add a pinch (1/8 teaspoon) of salt for each quart or liter of water boiled.
There are times when boiling water is not possible, for these times, chemical disinfection should be used. Chlorine and iodine are the two chemical agents that are often used to treat water. Chlorine and iodine are slightly effective in controlling Giardia, with chlorine being more effective. However, chlorine and iodine may not be effective in controlling Cryptosporidium, as it is a more resistant organism. Both Chlorine and iodine work best in warm water.
When using bleach, you want to add eight drops of liquid chlorine bleach (such as Clorox) per gallon of water. Use only bleach that contains 4 to 6 % sodium hypochlorite. Do not use scented bleach or bleach that contains other additives as these could cause you physical harm or even death.
Household chlorine bleaches usually contains 5.25% available chlorine and most will have a procedure written on the label for treating water. However, when the procedure is not given, then locate the percentage of available chlorine on the label and follow the table below as a guide for how much bleach to add per liter of filtered water.
DO NOT USE NON-CHLORINE BLEACH TO DISINFECT WATER!
Thoroughly mix the treated water and then permit it tocovered and stand, for approximately 30 minutes or longer. The treated water should have a slight chlorine odor, if it does not, then the process should be repeated. Allow the water to stand for an additional 15 minutes longer. If the taste of chlorine is too strong then allow the treated water to stand exposed to the air for a several hours, and then aerate the water by pouring it forth and back from one clean container to another.
Chlorine tablets can also be used to disinfect filtered and settled water. Chlorine tablets can usually be purchased from drug and sporting goods stores. When using chlorine tablets, make sure to carefully read and follow the directions on the packaging label. Use one tablet for each quart or liter of water to be purified if the container or packaging does not contain instructions for disinfecting drinking water.
How to use Tincture of Iodine to Disinfect Settled and Filtered Water:
Tincture of Iodine is commonly found in nearly every medicine chest or first aid kit and can be used to disinfect water. Add 20 drops of 2 percent iodine per gallon of clear water or 40 drops per gallon of cloudy water.
Iodine tablets can also be used to disinfect filtered and settled water. Iodine tablets can also be used to disinfect filtered and settled water and can usually be purchased from drug and sporting goods stores. When using Iodine tablets, make sure to carefully read and follow the directions on the packaging label. If the container or packaging does not contain instructions for disinfecting drinking water, then use one tablet for each quart or liter of filtered and settled water.
Water in water pipes and toilet flush tanks (not bowls) is safe to drink if the valve on the main water line was closed before the flood.
If your water comes from a well that has been contaminated with floodwater, you should continue to disinfect your water even after the floodwaters recede until you have your well tested and the test reveal no contamination. Immediately contact your local or state health department or agriculture extension agent for specific advice, as soon the floodwaters recede or as soon as you suspect that your well may be contaminated.
