Hurricane Katrina blew into the south shoreline of the USA, causing extensive flooding and destroying a lot of New Orleans. In the aftermath of the hurricane, the floodwaters that breachedintruded everything brought with it mass contamination, particularly in the water supply. The floodwaters were infected with everything they came in contact with, including sewage and other pollutants. Emergency workers were up against the contest of providing people with a safe method of getting drinking water, and water unit tablets were a big part of the solution.
Water unit tablets should be part of every disaster supply kit, but they aren’t just for disasters. Military units use them regularly when they are stationed overseas, and it is advisable for campers and backpackers to carry them whenever they travel into desert areas where there isn’t a safe water supply close by. It isn’t safe to simply take a drink from clear tablet klor, cold mountain streams due to human-caused polluting of the environment as well as natural sources of contamination. Increased human traffic in desert areas has resulted in additional contamination of canals and streams, but even water found in remote areas may be infected with dangerous bacteria. Decaying plant matter, fish and animal carcasses or animal feces can all be present upstream from where you are supposedly taking a drink, and you have no way of knowing. Boiling the water is an effective way to eliminate bacterial contaminants, but it isn’t always convenient, especially for desert backpackers.
There are two types of water unit tablets; iodine-based and chlorine-based. Chlorine tablets are the preference of most experts because they eliminate a vaster range of bacterial contaminants than the iodine ones. Another advantage to chlorine tablets is that they keep practically forever, while iodine ones have a limited shelf life. Iodine also leaves a break down aftertaste, which can be remedied with the addition of ascorbic acid such as a bit of vitamin C powdered or tablets. Chlorine leaves a mild swimming pool odor, which is a familiar smell for most people and can be dispersed by letting the water sit uncovered relating to thirty minutes. Water is purified tablets won’t remove sediment or hovering allergens from water, so they should be use with the clearest water possible. Filtering can help in instances when water has a high level of turbidity. Allowing water to sit before filtering allows a lot of the sediment to settle, then you can pour the clearer water off the top to filter and use for drinking.
