Boiling Water

Boiling kills parasites, bacteria and other pathogens in water. It does not, however, eliminate all forms of chemical pollution. Also, you’ll still need to filter out any solids. A camp stove ($10 to $150) is a good item to have on hand for boiling because your power might be out as well. Any camp stove will do, but a portable stove that burns wood is nice in case there’s a shortage of other fuel to purchase. Don’t use camp stoves indoors—they generate carbon monoxide.

It’s never too early to prepare your family and your home for hurricanes, severe weather or natural disasters. Use this “How-To” guide to help you protect your property and loved ones in advance of an emergency.

Be Careful With Bleach

Bleach is a readily available household item that can be used to purify water. Use only regular, unscented chlorine bleach with either 6 or 8.25 percent sodium hypochlorite as the active ingredient. Using a clean eyedropper and 6 percent hypochlorite bleach, add eight drops per gallon. For 8.25 percent, use six drops per gallon. Stir the water and let it stand for half an hour. If the water doesn’t have a slight chlorine odor, repeat the dosage and let it stand for 15 more minutes. In general, you’ll need more bleach if the water is cold or murky. Bleach has only a six-month shelf life, so be sure to keep a fresh supply.

Iodine

Iodine is another household chemical that can disinfect water. It is, however, a harsher chemical than bleach. On the upside, you can also use it to treat wounds. Using 10 percent povidone-iodine, add 8 to 16 drops per quart of water, depending on the water’s cloudiness.

* If there’s a flood, don’t assume your well water is safe. Test it.
