Whether it is a natural disaster or another serious issue, having clean drinking water is essential for survival. Ideally, you should already have several gallons of clean drinking water per person stored away for these types of situations, but the reality is that most people do not have the room or just have not taken the time to buy water and put it away. If you find yourself in the middle of a crisis and need to have access to clean drinking water, here are some things you can do. The Simple Boil Method Boiling water can be sufficient for killing off any bacteria found in it. Take a large pot of water and boil it for at least eight to ten minutes. If the power is out and you have a gas stove, you can use the stove to do this, but if you have an electric stove, you’ll need to boil the water over a fire instead. Make sure you let the boiled water completely cool, and then put it into tightly sealed containers until you’re ready to use it. Iodine Or Chlorine Iodine and chlorine can both be used to purify water, but this should be done very carefully. When using iodine, add about three drops per quart of water. If the water is muddy or looks cloudy, you may need to double the number of drops you add. Stir the water well and let the iodine sit for about one half hour. Then, filter the water before you drink it. You can also use chlorine in a liquid form to purify your water. This solution should contain 5.25 percent of a substance called hypochlorite, which will effectively kill off any bacteria found in the water. Mix one gallon of water to eight drops of the chlorine solution, or double the amount of drops for extra cloudy water. Keep in mind that adding the exact amount is important when using this method to avoid overdoing it. Charcoal Charcoal is a highly effective water purifier. In fact, most household filters found under sink faucets and in pitchers have a charcoal-based filter. If you’re in a pinch, use some grill charcoal and put it in a coffee filter. Pour the water over the handmade filter, and let it flow through. You may need to repeat this process a few times until the water is clear and so you can make sure any debris or other materials have filtered all the way through. While this method may not completely kill off bacteria, it is still a good way to help purify any source of water you have and works effectively at making your water better to drink.  For water...
