The guidelines of the World Health Organization and all the advice on How to make water drinkableboth in extreme situations and during simple excursions.
Staying hydrated is essential, whether in the wake of natural disasters that cause water mains disruptions, or while on outings, camping or hiking. In this article I will tell youhow to make water drinkableand what are the best sources of water to exploit as drinking water.
L'World Health Organization,in the event of a tsunami, earthquake and other natural disasters that prevent access to the water supply, he recommends drinking only bottled water or using water after boiling.
In sedentary conditions, the safest water supply consists precisely in stocking up on bottled water, however, in the case of traveling camping or in other situations, it is not convenient to carry a very heavy load of water with you. In these conditions, it is necessary to intercept the best water sources and understand how to make water safe and efficient.
The sources of water
Water is not just that which flows into the city water network. Nature is rich in natural sources and many of these are located in pristine contexts, far from pollution and urbanization.
It is in these contexts that you can fill your water bottles with a light heart ... however, there are rare circumstances in which you can come across an uncontaminated source. During a trip out of town it is always important to provide forwater purification,regardless of the source.
- Lakes, ponds and rivers
Lakes and ponds are not ideal water sources. They can have high levels of bacteria and other microorganisms. Rivers are also not so safe, it is true: they come from the mountains but currently it is difficult to find a river that is not contaminated by human pollution. Especially stay away from rivers that flow near urban centers (they can have sewage drains!) Or industrial centers (they can collect chemical waste).
- Snow and ice
It is not recommended to hydrateeating snow or icebecause doing so would lower your body temperature. Rather, you can collect snow and ice and purify it only after melting it.
- Water wells
A water well can be a blessing in the middle of the desert or in remote locations ... however, pathogens of all kinds can contaminate this source. Even in this circumstance it will be necessarypurify the water.
How to purify river, well, rainwater ...
The most effective way to remove viruses and bacteria from water is simply to boil this liquid. Forpurify the wateryou simply have to bring the water to a boil over high heat, quickly, and boil it for 60 seconds.
Other method forpurify the wateris filtering. There are thousands of purifying filters on the market. There are activated carbon filters, ceramic filters, reverse osmosis water purifiers, purifiers with sieves and micropores and others that treat water with iodine or another chemical that can deactivate pathogens. Water purifiers are very convenient but can also be very expensive.
THE chemical purifiers they can consist of drops to be diluted in water (2% iodine tincture) or tablets to dissolve (also in this case, the chemical principle is the iodine element). Other tools are able to transform water into drinking water using UV rays that can deactivate viruses and bacteria. Still, other devices manage to purify the water using solar energy.
