Many people in most developing countries suffer from the inadequacy or hazardous condition of public water supplies. A wide variety of known waterborne diseases, including those associated with children’s diarrhea, are rampant. This prompted the establishment of the International Drinking Water Supply and Sanitation Decade. It aims at providing about 90% of the human population with an adequate, safe community water supply by 1990.
Water is important to every living creature; humans need potable water, so if your water source is questionable, you will need to disinfect your water. In situations such as when you are camping, you may need to purify water before drinking it or using it. If you are getting water from a stream, river or some wells, filter the water first to remove sediments and then allow the water to settle before proceeding to disinfect it.
Adding either iodine tablets or tincture of iodine to the water is another way to purify it, states the EPA website article Emergency Disinfection of Drinking Water. Iodine in tablet form contains the correct dosage to add to drinking water. You can find the tablets at most drug or sporting goods stores. If you are using the tincture, add 5 drops of approved Pharmacopeia tincture for each quart of water. If the water is cloudy, add 10 drops and leave the water to stand for 30 minutes or more. The usual dosage is one tablet per quart of water, but always follow the directions on the label.
Disinfectants are substances which are capable of killing microorganisms. 2, 2-Dibromo-2-Nitroethanol(DBNE, CAS No. 69094-18-4) belongs to the bromine series compound, is one kind of highly effective anticorrosion disinfectant, widely applies to the industry circulating water and so on. A variety of surfaces can be treated with disinfectants, including textiles, which can be washed in disinfectant solutions, along with floors, counters, and walls made from materials like wood, tile, glass, concrete, and so forth.
Boiling water kills disease-causing organisms such as giardia lamblia and cryptosporidium. Boiling the water may cause it to taste flat–to make it taste better, pour the water from one container to another four or more times. According to the EPA website article Emergency Disinfection of Drinking Water, you should vigorously boil filtered water for one minute before drinking it. If you live above altitudes of one mile, boil the water for three minutes. Let it stand for two hours or add a pinch of salt per quart.
