Preparing For Alternative And Emergency Water Supplies

There are many emergencies where drinking supplies might be threatened. These include events such as hurricanes, tornadoes, and floods. Severe winter weather can also cause a need for an alternative supply. Also, persons preparing for certain emergencies such as war, food shortages, and a grid system breakdown are concerned with pure drinking supplies. Humans can live for some time without a food source, but need hydration within a few days.

Purified water means chemicals have been removed by some method. There are several ways to do this. Radiation is one way, as is distillation. Deionization is another method sometimes used. Different methods of filtration can also remove minerals, sometimes only certain ones. The result is then bottled and sold to consumers. It may be stored for some time for emergency use, or used as a source safe for drinking.

Some manufacturers add certain minerals back in to improve both taste and nutritional value. There is some debate as to the benefits of the lack of minerals. The naturally occurring minerals have many benefits that are lost when they are removed. Thus, complete purification may not be advisable for drinking uses. Though purification can remove unwanted substances, the necessary minerals may need to be added back.

The low electric conductivity of this altered product makes it perfect for use in certain machinery. The absence of minerals makes it less able to conduct electricity, which is preferred for certain uses. The lack of mineral salts means it doesn't clog things such as irons, coffee pots, filters, and other products.

The method of filtration determines the purity of the end product. Different uses require different degrees of purity. For example, for lab work and mixing medicines, it is imperative that purity be excellent. However, for other uses, such as drinking, using in machines and appliances, small amounts of trace elements left behind are appropriate, and even sometimes desired.

Nursery water is another use for purification. It has been treated to remove all minerals, then certain beneficial ones are added back. This is then used to mix baby formula, dilute juices for babies and toddlers, and to mix with baby cereals and other dehydrated products. Its greatest benefit may well be for travel, as there is no worry about impurity of available sources, or the stomach upset that can be caused by a change in what is used for the baby or small child. With the availability of the same product used at home, there is less worry and more enjoyment when traveling.
