Water purification will be a greater and more expensive problem as the global population continues to rise. 90 percent of the worlds’ water is contaminated in some way. Biological organisms and chemical toxins increasingly contaminate our water supplies. These cause serious, and sometimes deadly illnesses. Biologically contaminated water can cause intestine infections. This can cause vomiting and diarrhea resulting in fluid loss. Toxic water is chemically contaminated from pesticides, acid rain, etc. Boiling, filtering, and/or chemically treating water does not remove chemical toxins. Boiling, filtering, and/or chemically treating water are three ways to kill microorganisms. The most certain way of killing all “bugs” is to boil water. In the time it takes for the water to boil, all bacteria will be killed. Let the water boil for at least one minute.
There are two types of water purification, iodine and chlorine.Chemical treatment of water is related to it’s temperature and the quality of the water to begin with. Muddy water needs more chemical to purify. Strain it with a cloth first to remove as much solid waste as possible. After the liquid chemical is added, allow the water sit for at least half an hour to let purification occur. If using water purification tabs, let the water sit for half an hour after they have dissolved. Read and follow the instructions provided.
The colder the water, the more time the chemical needs to do it’s job. If the water temperature is below 4° C (40° F), the treatment time doubles before drinking. After the expiration date the tablets have no effect and should be replaced.
Iodine and Chlorine
Some people can’t use iodine. These are people: • on lithum • with thyroid problems • women over fifty • pregnant women – Check with your doctor if you have doubts. Chlorine is a substitute for iodine. Use either a chlorine chemical or a filter that doesn’t use iodine. Sediment levels, time, and water temperature all play a part in killing microorganisms in the water.
The cleaner the water to begin with, the less purification required. The colder it is, the longer it takes. One system can fail, therefore it’s good to have at least one backup method for water purification. If you don’t have filters and/or chemicles, boil the water. Filters Water filters allow water to pass through a microscopic filter. Viruses are small enough to get through these filters so use chemicles also. There are systems that pass the water through both iodine and a filter. This will kill the smaller organisms that get through the filter. Some water filters are sealed and if the filter is hit it could crack. If the filter is cracked it’s useless. Be careful. Adding a small amount of vitamin C to your water after the purification time with the iodine will make the water practically tasteless.
