Water purification is the removal of chemical, biological contaminants and suspended solids from water. You can use physical processes like filtration or chemical processes like reverse osmosis to purify water.
Water that appears clean may still have harmful bacteria such as Giardia, Cryptosporidium and others, which can be invisible to the naked eye. You should purify any water you drink, no matter how clean it looks.
Water
Water purification in the wilderness is possible. Untreated water can cause illness and is especially dangerous when it's contaminated with viruses, bacteria and parasites.
No matter whether you are traveling in the wilderness, or on vacation it is a smart idea to have a filter. These devices remove large particles and treat water with chemicals that kill parasites and germs.
Many filters have an interior element or cartridge with microscopic pores. This captures bacteria, protozoa, and debris. Filter effectiveness decreases as strained material gums up these pores. You can use iodine or other similar chemical treatments to combat this problem. These products are readily available at most outdoor shops.
Filtration
Water purification is an important skill you should keep in your bug-out kit. It allows you to stay hydrated in the wilderness. It removes potentially harmful pathogens, viruses, and other contaminants that could lead to waterborne illness.
Filtration refers to the process of separating solid particles from liquids and gases by using a medium called filter. The fluid that passes through the filter is called the filtrate, while the solid material that remains on the filter is the residue.
Boiling
Boiling water is an efficient and safe way to purify your drinking water. It kills bacteria as well as parasites that could cause waterborne diseases such cryptosporidiosis, giardiasis, and others.
It can also remove any cloudy water. It is a smart idea to filter the water before boiling to get rid any large particles or bacteria that could be harmful.
Another way to boil water without a pot is to place a container over a fire and surround it with dry rocks. This works well because the rocks absorb heat from the flames and can then transfer it to your water.
Chemical Treatment
Chemical treatment refers to the use of chemicals in order to remove pollutants from water. It can be used to remove hazardous substances. However it needs to be determined based on the properties of the pollutants and their environment.
Most chemical treatment are intended to treat water from lakes, streams, and other surface water sources. These waters usually contain sediment (sand and clay), chemicals and toxins.
Purification Tablets
Water purification tablets make a great addition for any backpacker, camper, or traveler who is looking to survive in the wild. These tablets can kill bacteria or other pathogens and provide safe, clean water.
These tablets usually contain iodine (or chlorine), which can activate microorganisms, such as parasitic protozoans. If ingested, the chemicals kill them.
These products are quick and easy to use to disinfect contaminated water. Follow the directions on the bottle to make sure you are using the correct amount of tablets for the water you are treating.
FAQ
What should you do first in a survival situation
In an emergency situation, you must assess the situation first. You need to know what is happening around you, where you are and how you got there.
It is also important to understand what you can expect from the environment. If you live in a remote area, communication may be impossible.
If you don’t know anything, it is a good idea to learn as much as you possibly can.
If you are in urgent danger, it's best that you seek medical help immediately. You can take your time and gather information if you feel safe.

Is it going to be used to open bottles or cans of beer? Do you intend to open packages and boxes?
Is your knife strong enough to handle heavy loads?
You might want to clean it after each use. Are you planning to wash it often?
Does it need to hold its edge well over time?

How To
How to Build an Lean-To Shelter
The United States has many small structures called lean-tos. Lean-tos are usually made of wood or metal poles and covered with tarps or canvas or plastic sheeting. The roof is usually added after the walls, ceiling, and floor are built.
A leaning-to is temporary shelter built on the side a building to provide shelter when it is too cold or rainy to build a permanent shelter. You may also call it a "lean to shed", "lean–to cabin," or "lean–to house".
There are many types, including:
-
A simple wooden frame covered in tarpaulin. This type is often seen in rural areas.
-
A lean to tent that consists of a framework made of poles and supporting a Tarpaulin.
-
A lean-to-cabin, also known "cabins-on-frame", consists primarily of a platform supported via beams and posts.
-
A lean-to shed, also called a "shelter-on-a-pole" or "paddock shed," consists of a framework of poles and supports with a cover.
-
A lean-to-garage, also known as "garage -on-stilts", or "overhang", is composed of a steel structure that rests upon concrete stilts.
-
A leaning studio, also known as "studio -on–a-frame" or simply "studio -on–a-post", is made up of a framework with two parallel horizontal members ("posts”) and one perpendicular component (beam).
-
A lean-to greenhouse, also called a "greenhouse-on-a-post," consists of three parallel horizontal members (posts), one perpendicular member (beam), and a canopy.
