About two thirds of your body weight is composed of water, this water aids in circulation and other bodily functions like breathing. If you are losing more water than you’re drinking, you get dehydrated. As you dehydrate your blood becomes thicker and loses volume. Your heart will have to work harder to circulate your blood, which will weaken your physical and mental abilities. If you only stock up on one item, please make it water. You can’t survive without it.
How long will your bottled water last? Hopefully you’ll eventually have a few cases stored at home. The average woman needs to consume 2.2 liters or almost 6.5 cups of water just to maintain optimal bodily functions. It’s important to remember the following tips whenever you think you may experience a water shortage due to the electric grid being down, or contamination.
At first warning, fill all available containers in your house with cold water. Think about the obvious holders - the bathtub, sinks, buckets and or plastic bins that you might have around. At this point don’t worry about disinfecting them, this is an emergency and you’ll need to disinfect the water that you’ll use for drinking. Don’t bother collecting warm or hot water as this comes from your hot water tank, and can be stored there directly for later use. Don’t forget all the ice cubes in your freezer - they can be melted for use as drinking water, which is a good reason to keep your trays full. Generally, unless otherwise notified by officials or during a flood situation, water that comes from your tap in the US is drinkable.
During an emergency or survival situation, any water that hasn’t been bottled especially for human consumption will need to be disinfected. The EPA provides specific information on their web site, but I’ve condensed it here for you. These methods are for filtered and settled water. Use an old t-shirt, or other cloth to filter the water first and then let it stand until any sediment sinks to the bottom. Pour off only the clear water on top.
Boiling - this is the surest method to make water safe to drink and kill microorganisms such as Giardia lamblia and Cryptosporidium. If not neutralized, Giardia may cause diarrhea, fatigue, and cramps. Cryptosporidium may cause diarrhea, nausea and/or stomach cramps and is highly resistant to disinfection. Boil filtered and settled water vigorously for 1 minute (at high-altitude, boil for 3 min). To improve the taste following boiling, you can pour it back and forth from one container to another to aerate and then let it stand for a few hours.
What if your gas and electric are off, or if you’re lost in the outdoors, how can you disinfect your water then? It’s suggested that well water is a preferred choice, but that might not be available. The next choice would be a river or lake, or other smaller source of natural water. Remember to stay away from sources that look polluted or stagnant. Flowing water is usually a better quality. If boiling isn’t possible, chemical disinfection of filtered settled water will keep you hydrated and is better than no treatment at all.
Chemical Treatment- Chlorine and iodiine are the two chemicals most commonly used to treat water. Neither treatment will be highly effective against the two microorganisms mentioned above - but some disinfection is better than none. Only use household chlorine bleach, do not use non-chlorine bleach, or bleach labeled for colors only. Most household chlorine bleach will be 5.25% available chlorine. Follow the directions on the label for disinfecting water. If you can’t find those instructions, the general rule of thumb is 2 drops per quart, or 8 drops per gallon (8 drops is approx 1/8 teaspoon). If you don’t know what strength bleach you have, use 10 drops per gallon. You’ll need to double the amount of chlorine bleach if the water is cloudy or murky or extremely cold. Mix thoroughly and let it stand covered if you can for about 30 minutes. The water should have a slight chlorine odor, but if it doesn’t repeat the dosage again and let stand 15 more minutes. If the chlorine smell is too strong, let it stand exposed to the air for a few hours and/or pour it from one clean container to another several times.
Common household iodine found in your medicine chest may be used to disinfect water. Add five drops of 2% tincture of iodine to each quart or liter of clear water. Cloudy water will need 10 drops. Let the mixture stand for at least 30 minutes.
What if you don’t have any of these methods available? That’s coming tomorrow…….
