3. What is potable water You may be asking yourself what is potable water, but the answer is fairly simple. Potable water has been filtered, cleaned, or treated to meet the standards for drinking water, meaning that it is reasonably clear of contaminants and harmful bacteria. This makes the water safe for drinking and cooking. Water purified via reverse osmosis, distilled, or UV filtered and water treated within municipal water systems all qualify as potable water. Most non-potable water will be raw water from ground wells, springs, ground water, rivers, or lakes that is not treated. It is not safe to drink as there are unknown contaminants in untested water. It is possible for non-potable water to taste normal, but carry health risks.

4. Purification process to get potable water Water wich contains dissolved salts may not be fit for drinking. It may also contain harmfull microorganisms in it. The water that you get in your taps is made potable, or fit for drinking, by the municipal corporation of your city. The water taken from the source passes through the following steps in a water treatment plant. The water from the source passed through screen filters which remove large insoluble particlse like twigs, leaves, etc.,. Alum is added at this point. Earlier you studied how alum helps in settling fine particals of clay which may be suspended in water. This process is called coagulation.

5. The water is then allowed to a settling tank. Heavy sediments settle down here. This process is called sedimentation. The clear water from the top is now passed through beds of sand filters to remove any left over insoluble solids. This step is called filtration. Finally, a small amount of chlorine gas is passed through water in a chlorination tank. Chlorine kills any harmfull microorganisams. That may be present in water. The water is now safe for drking. It is stored and then supplied to the people in the city through a network of pipes.

6. Use purification tablets or drops.  You can purchase these drops or tablets at sporting goods and adventure stores. Keep in mind that this is not the best tasting method, but protection from bacteria is worth a bitter taste in your mouth . Other purification methods Use a pump purifier.  You can use these types of purifiers in conjunction with a canteen or water bottle when out in the wilderness. These pumps are generally hand held and made out of a synthetic or ceramic cartridge. Most filters have two separate hoses, one for clean water, the other for dirty water.     boiling the water. When bubbles begin to appear, it means that the water is starting to boil, but continue heating until the water goes into a hard, rolling boil, then start timing. Continue to boil the water for 5-10 minutes plus 1 minute for every 300m above sea level, up to around 5500m where boiling becomes ineffective, to have the most effect upon any bacteria and other micro-organisms .

7. Form a cone out of a strip of bark.  Birch bark, or a bark similar to it, is best for creating this filtering system because it is flexible but will keep its shape . Layer the cone.  Wildwood Survival suggests layering the cone with sand, charcoal, grass, and gravel (or small rocks.) Pour the water through the cone and into a container.  Do this several times to increase the amount of purification that occurs. How to purify water into portable water in wild

8. FAQ’s about potable water how does potable water relate to our health Ans. Water with contaminants can lead to various health issues, such as neurological disorders, reproductive problems, and gastrointestinal issues. Those who at a higher risk of developing an illness following consumption of contaminated water include people who are immune-compromised, the elderly, pregnant women, young children, and infants. An example would be high lead levels leading to serious health complications, particularly in young children and pregnant women. As such, there are Federal laws in place that require systems to reduce specific contaminants so they fall under set levels, protecting the health of the general population.

9. 2. How does potable water become contaminated Ans. There are various contamination sources for water systems. The most common sources which lead to contamination include: Malfunctions in wastewater treatment systems (such as nearby septic systems) Sewer overflows Manufacturing processes Use practices on local land (such as concentrated animal feeding, livestock, pesticides, and fertilizers) Chemicals and minerals which occur naturally (such as uranium, radon, and arsenic)

10. 3.Is drinking bottled better than tap water Ans. It is common to worry about getting sick after drinking tap water, particularly because of news stories, such as those related to the Legionella outbreaks. These people will choose to install a water purification system (which is frequently expensive) or simply drink bottled water. In reality, however, there have been various studies that show that people who take these steps are actually wasting their money. Bottled water is an expensive item to purchase and it can actually be dirtier than the tap water, depending on where you live and the bottled water you buy. To remain safe, ensure that what you buy is potable water by making sure that the company supplying the water is part of the IBWA (International Bottled Water Association) as this ensures that they live up to the rigorous testing requirements for drinking water.
