How To Filter Water In The Wild

Top Ways to Purify Water in the Wilderness

Recently, there have been several reports of lone hikers becoming stuck in the woods for days on end, and all of them were able to make it back to civilization thanks to their will to survive and, less noticeably – but most significantly – a supply of water. Despite the fact that a human may survive for weeks without food, they can only last 3–5 days without water, and in high temperatures, they may only last a few hours. Yes, overhydration can cause issues, but water is still required by your body in order for your organs to work properly.

1. Boiling

Boiling water is the quickest and most effective method of purification, given that you have the necessary tools and a campfire or camp stove. Bring water to a boil in a saucepan over high heat until rolling bubbles appear, and allow them to continue to roll for at least five minutes. Then wait for it to cool down before drinking it, otherwise you’ll scorch your lips and tongue, as you’d expect.

2. Filtration or purification pumps

Visiting a camping and outdoor supplies store will almost certainly reveal a wide variety of pumps equipped with filters and purifiers to ensure that non-potable water enters but only drinkable water exits – directly into your water bottle. This is accomplished by the use of a method that involves pressing water through a ceramic or charcoal filter and treating it with chemicals. Some high-tech water bottles have this procedure integrated into them, eliminating the need to pump water into a separate container; instead, the purifying process occurs while you squeeze or suck water straight into your mouth, saving you time and money.

3. Purification drops and tablets

Adding a few of purification tablets or drops to wild water is a simple and affordable means of purifying it, although it is not always the finest taste option. The most commonly utilized chemical is iodine, but other options such as chlorine or potassium permanganate are as effective. Allow the chemicals to treat the water for at least 20 minutes before drinking it, then mix it with powdered mixes to hide any flavor that may be left over from the treatment.

4. Make an evaporation trap in the ground.

All of the above solutions either the transport of water or the presence of a local water source – but what if you don’t have access to either? As explained on NatureSkills.com, you may extract moisture from the ground by digging a hole in the ground and placing a container on the bottom of the hole to collect the moisture. Cover the hole with plastic to ensure that no moisture escapes, and place a small weight (a rock, for example) in the center of the cover to create a dip in the middle. When water evaporates from the ground upwards, it condenses on the cover of the container and drops into the bottom of the vessel.

Of course, this third technique is not the most expedient manner of obtaining potable water, so make a point of remembering to bring some with you. Keep this strategy in mind, along with a container and some form of plastic cover, in the event of an emergency, though.

Wood filters, hot rocks, and seven other ways to purify water in the wild

This article was first published on the website Outdoor Life. In an emergency situation, finding and disinfecting enough drinking water to meet your needs is one of the most important survival considerations. If you find yourself in a crisis position in the desert after being lost or in your own house after a natural disaster, remember that the human body can only survive for three days without any kind of drinking water. It’s a good thing there are plenty of water sources available across much of the world, as well as several methods of disinfecting the water.

See what happens if you keep reading.

Finding a water source

It is necessary to locate the water before it may be disinfected. In different parts of the world, water might be abundant or scarce, depending on your location and condition. Freshwater surface sources such as streams, rivers, ponds, and lakes can provide water for human use. If you have the ability to distill the water, you may even utilize brackish or salty water as a source if you have the proper equipment. Let’s not forget that precipitation can serve as an emergency water source in a pinch.

Fresh rain that didn’t fall through a jungle or forest canopy should be safe to drink straight from the source, according to the CDC.

Water that comes from springs and other subterranean sources is generally considered to be safe in most locations.

However, the majority of other water sources should be deemed contaminated and should be disinfected using one of the procedures listed below.

Boiling

Give those pathogens a death bath by drowning them with it. Tim MacWelch is a well-known actor. Water should be boiled in order to eliminate any parasites, bacteria, or other pathogens present. This is the most reliable method of killing pathogens in water. Although boiling will not completely eliminate all types of chemical contamination, it is still one of the safest techniques of disinfection available to us today. Most organisms will be killed in five minutes of a rolling boil, but ten minutes is preferable for safety.

It is possible to boil in a metal, ceramic, or glass container over an open fire or on a stovetop.

This container might be anything from a rock depression to a wood bowl that has been burnt, to a folded bark container, to a hide, to an animal stomach. Avoid using quartz or any other river rocks since they have the potential to explode when heated.

Distillation

A solar still, such as this one, will assist you in collecting water from the ground. Tim MacWelch is a well-known actor. In the aftermath of a disaster, your water supply can become contaminated with radiation, lead, salt, heavy metals, and a variety of other toxins, and attempting to filter them out will simply cause damage to your pricey water filter. The alternatives are limited in a situation when the only accessible water is potentially hazardous to human health and safety. Water distillation is the most secure method of disinfection.

  • Distillation will not eliminate all potential pollutants, such as volatile oils and some organic compounds, but it will remove the majority of heavy particles that would otherwise remain.
  • The fact that the canner remains intact is the nicest feature of this operation (apart from the availability of clean water).
  • The only difficult aspect is attaching the copper line to the steam vent on the canner’s lid, which can be difficult.
  • To construct one, lay a square of transparent or milky plastic (5 by 5 or 6 by 6 feet) over a 3-foot-deep hole and set a clean container in the center of the square of clear or milky plastic.
  • Place a rock in the center of the plastic to make a cone that is approximately 45 degrees above the container.
  • Increase the amount of water that is produced by the hole by adding green plants and even urine.

Survival straws

Survival straws can filter water just before it hits your mouth, saving you time and effort. Tim MacWelch is a well-known actor. The straw kind of water filter is one of the tiniest and lightest water disinfection products to have recently entered the market. Newer types may be used in the same way that a drinking straw would be, and they can also be connected to the drain valve on a water heater to clear out any water that may have accumulated in the heater following a disaster. They may also be attached to a garden hose in order to filter the water that passes through it.

The majority of these filters have an activated carbon filter element, which not only removes bigger germs and pathogens from the water, but it also removes unusual smells and aromas from it as well.

Filters

Gravity-fed filtration systems, such as this one, are most suited for situations when you are not in a hurry. Tim MacWelch is a well-known actor. Pump-action water filters and drip/suction water filters are the two most common types of water filters in use today. The former employs a pump to drive raw water through a filter cartridge, whilst the latter does not. The latter are filter cartridges that operate on a gravity drip principle (similar to an IV bag) or that are installed in line with hydration bladder hoses to filter water.

The Katadyn Pocket filter has been my go-to for years and continues to be so.

Ceramic screens out bigger pathogens, whereas silver kills or disables tiny organisms such as viruses and bacterium The majority of these filters have a flow rate of roughly a quart per minute.

Ultraviolet light devices

UV radiation may destroy tiny organisms, however it is best used on pure water to have the most effective results. Tim MacWelch is a well-known actor. Small organisms are particularly vulnerable to the harmful effects of ultraviolet radiation. Using it as a disinfection method, it has proven to be remarkably efficient. Hand-cranked water purifying devices such as theSteripen Sidewinder, which does not require batteries, destroy the DNA of illness-causing microorganisms in a matter of seconds.

When dealing with water that contains huge floating particles (which germs can hide behind or inside), these devices will not be 100 percent effective, but they will be successful when dealing with clean water of doubtful origin.

Solar water disinfection

Although it appears to be simple to cure water with sunshine, there are a few disadvantages. Tim MacWelch is a well-known actor. Solar water disinfection (abbreviated SODIS) is a water treatment process that disinfects water by utilizing the sun’s radiation. The most often used procedure is to expose plastic bottles full of polluted water to the sun for at least one day, preferably longer. Almost all biological threats in water are killed or damaged by the sun’s copious ultraviolet radiation.

Because it’s simple to use, it’s affordable or even free, and it provides effective bacterial and virus disinfection (albeit not comprehensive or guaranteed).

However, there are certain issues with the methodology.

This product cannot be used in the rain, and it provides no residual disinfection.

The water and the container must be transparent, and the bottle should not be made of glass. To make matters worse, this approach offers no protection against chemical contamination and can only handle tiny bottles (up to 2 liters in volume).

Disinfecting tablets

Depending on your condition and the pills you choose, you may have to choose between speed and flavor. Tim MacWelch is a well-known actor. The Micropur pills from Katadyn and the iodine tablets from Pottable Aqua are two of the most frequent and popular water disinfection tablets on the market. They are both capable of doing their jobs well, yet there are some disparities between them. In the case of purification tablets, the shelf life of the product should be taken into consideration when equipping a cabin, cave, or bug-out bag with the product.

  • That’s not awful, but Katadyn’s Micropur pills have a shelf life of at least two years.
  • When it comes to speed, Potable Aqua is unquestionably the best option.
  • To obtain their maximal disinfecting activity, the Micropur pills must be taken for a full four hours.
  • Iodine’s toxicity and flavor might be a touch off-putting for some people.
  • When it comes to picky youngsters, they are known for refusing to drink the iodine-infused water, which can result in dehydration and other dangerous consequences in an already tense situation.
  • Overall, Katadyn Micropur pills are more expensive and take longer to work, but they last longer and are well accepted by the majority of the population.

Household chemicals

Either bleach or iodine can be used to disinfect water with acceptable results if they are used properly. Tim MacWelch is a well-known actor. Either bleach or iodine can be used to disinfect water with acceptable results if they are used properly. Generally speaking, the amount of chemical you use will be determined by the quality and temperature of the water you are using. The amount of disinfection required for cold or muddy water is somewhat more (four drops per quart) than for warm or clear water (two drops).

  • Then, turn the bottle upside down and unscrew the cap a turn or two at a time until it comes off.
  • Close the container tightly with the lid and wipe the outside of the bottle to ensure that the chlorine is evenly distributed.
  • When you open the bottle after the given time, it should have a chlorine-like odor when you open it.
  • When it comes to water safety, don’t take any chances or shortcuts.
  • You may also disinfect your water using one of the two most prevalent kinds of iodine.
  • It is crucial to know whatever sort of iodine you are taking before you begin using it.
  • Allow the solution to remain in the shade for 30 minutes after adding 5 to 10 drops of tincture of iodine 2 percent to 1 quart of water.
  • Use five drops for clear or warm water, and up to ten drops for cold or foggy water, depending on the situation.
  • If you want nice-looking water, use fewer drops.
  • Wait while you clean the bottle.

Another advantage of iodine products is that they may be used for wound disinfection as well as for other purposes. Chlorine does not do double duty in this manner, and it is never recommended to apply bleach to wounds. When disinfecting water, never mix iodine and chorine together.

Build your own filter

Filters constructed of wood have the potential to revolutionize the water filtration industry throughout the world. Tim MacWelch is a well-known actor. Those survival books with a water filter built out of charcoal-filled jeans hanging from a tripod are all too familiar to most of us. We are sorry to break your bubble, but that system is not a dependable source of information. Although it will filter out bigger particles, don’t expect bacteria- and virus-free water to emerge from this gadget.

  1. Because of its structure, the sapwood already has a filtering activity in the live wood, preventing air bubbles from forming in the tree’s sap.
  2. Some humanitarian organizations are taking a close look at conifer wood as a widely available material for water filtration systems in underdeveloped countries because of the effectiveness of this type of filter.
  3. It was necessary to tie this chunk of wood to a water supply with the help of a PVC pipe and some epoxy in order to prevent water from circumventing the wood filter.
  4. coli was completely removed.
  5. However, even if viruses may be able to get through the wood (since they are much smaller than bacteria), some water filtering is preferable to none at all.

Drink it raw

Untreated water is dangerous, but if you’re about to perish from dehydration, it can be your last alternative to save your life. Tim MacWelch is a well-known actor. Drinking untreated water is unquestionably a gamble. It is possible that even in the most pristine wilderness locations, the water might be tainted with microorganisms that cause gut discomfort. Drinking unprocessed water is dangerous at best unless you are fortunate enough to come upon a spring that is pumping pure water from the ground’s natural water table into the spring.

However, there are always exceptions to the rule.

It is preferable to be alive and ill by diseases than to be dead and unaffected by pathogens.

Bonus: build a water bottle survival kit

Choose a bottle with a large opening to make it easier to remove the things. editor(s) of Outdoor Life Online An empty bottle of water can be an extremely precious commodity to a person who is thirsty, but it is not just the water that has value; the bottle itself can serve a variety of functions.

One of the most practical use is as a container for a survival kit. Here are some things to put in your bottle, whether it’s made of plastic or metal.

The gear

The components of your water bottle survival kit might be complicated and diversified, or they can be straightforward and practical. Whatever you decide to include in the kit, it’s a good idea to have a significant amount of redundancy. When your life may be dependent on a little collection of equipment, having a backup plan is always a wise decision.

  1. A folding knife and/or a tiny multitool are recommended. Button compass with liquid filling
  2. Batteries for a small LED flashlight or squeeze light, with an extra set of batteries
  3. A lighter, a ferrocerium rod, and tinder tabs are all included. water purification pills in the amount of 40
  4. Signaling with a mirror and a whistle a blanket for outer space
  5. A magnifying glass (for use as a backup fire starter)
  6. 550 cable, 50 feet in length
  7. Kit for fishing, which includes: 30 yards of monofilament line, 10 bait keeper hooks in a variety of sizes, and split shot
  8. 2 big and 2 tiny steel safety pins
  9. 4 steel safety pins A little first-aid kit is included. a few feet of duct tape (which might be wrapped around the bottle itself)
  10. A pair of scissors When the bottle is being used to carry liquid, a little bag to keep all of this equipment together

The bottle

Water bottles made of stainless steel with a single wall are one of the most innovative pieces of outdoor equipment to enter the market in recent years. This tough vessel is not only crack- and crush-resistant, but it can also be used to boil water to make it safe to drink. It is also dishwasher safe. Important note, however: if you are boiling water in a metal container, the bottle must be constructed of either single-wall stainless steel or another fire-friendly metal, such as titanium, and must be free of any paints or coatings.

The heat will not pass through the vessel adequately, and the vessel will most likely explode.

If you prefer to use plastic, make sure to use a container with a large opening so that the things can be removed easily.

This provides you with the boiling option in a convenient and adaptable container.

How to purify water in the wild: 6 methods to help you avoid tummy troubles on the trail

Learning how to filter water in the wilderness might spare you from a trip to the hospital or from spending the next week or so not being more than 10 feet away from the nearest toilet (!) (Image courtesy of Getty) When we’re out trekking in the wilderness, the physiological fluids we lose via effort and perspiration must be replaced on a continual basis — at a rate of around one liter every two hours of hiking, according to most authorities.

However, getting enough safe, clean drinking water into the system (see our explainer, Water for hiking: how much do you need?) can be difficult, especially when our trails take us deep into the backcountry and replenishing our supplies of H2O necessitates drawing it from natural sources such as streams, lakes, creeks, rivers, and springs.

As a result, understanding how to purify water in the wilderness – and dedicating the necessary time to do so – is critical for any hiker wishing to avoid a trip to the hospital or an extended period of time in the commode.

Why purifying water is important

The presence of water-borne bacteria, protozoa, or viruses can completely derail a hiking or backpacking trip in a matter of minutes. The most prevalent of them are as follows: Giardia and cryptosporidium are parasites that cause diarrhea. Infections caused by protozoa found in human and animal feces that can result in severe gastrointestinal disease (vomiting, diarrhea, and cramps). Both are common in most rural areas of the world, especially in developing countries. Dysentery and amoebic dysentery are two types of dysentery.

Fever, bloody or mucous diarrhea, chills, and stomach pain or discomfort are some of the signs and symptoms.

Bacteria Shigella, E.Coli, salmonella, and campylobacter are some of the most prevalent water-borne bacterial illnesses, and all of them are potentially lethal.

None of these contaminants can be removed by water filtration systems, although they can be removed by UV pens, boiling, and certain purification tablets, among other methods. The practice of drawing water directly from the source is not recommended (Image credit: Getty)

How to purify water in the wild: 6 methods

Boiling Boiling is one of the most effective methods of purifying drinking water obtained from natural sources. One of the reasons for this is because none of the viruses that are typically found in natural water can endure temperatures greater than 170 degrees Fahrenheit. Given that water boils at 212 degrees Fahrenheit at sea level and at 200 degrees Fahrenheit at heights of around 14,000 feet, boiling will safely destroy any water-borne pathogens if done correctly. According to general guidelines, you should strive to have your water at a boiling, rolling boil for at least 2 minutes before it can be consumed.

  1. If you’re camping, you won’t need to bring anything special.
  2. A camping stove of some sort is required to be carried on the trip.
  3. They weigh next to nothing, and a blister pack of ten tablets – which may cure up to 10 liters of water – takes up about the same amount of space as a standard stick of chewing gum.
  4. However, while the majority of tablets are efficient in eliminating the vast majority of bacteria, viruses, and germs, iodine is ineffective at eliminating one of the most frequent water-borne pathogens – Cryptosporidium – and both leave your water taste a little strange.
  5. It is simple to use CheapCons Doesn’t filter out any mud or silt for us.
  6. Pregnant women and individuals suffering from thyroid problems may be at danger from iodine exposure.
  7. Most versions are really simple to use; all you have to do is fill your water bottle (see: top hiking water bottles) with purified water and then swirl the water with your purifier pen for 1-2 minutes, and you’ll have safe to drink water.

How to Filter and Purify Water for Traveling, Camping, and Survival

For the vast majority of people in the industrialized world, getting a drink of safe, clean, and tasty drinking water is as simple as turning on the faucet. Outside of the comfy confines of one’s own house, however, obtaining potable water can be more difficult and time-consuming. Perhaps you went hiking with all of the necessary equipment, but you just did not bring enough water with you on the trip to keep you hydrated. Alternatively, you may be traveling in a developing nation where you have been advised not to drink from the tap.

In these conditions, how would you go about obtaining safe drinking water?

It is true that there are several alternatives for filtering and purifying water, but regrettably, some of the terminology associated with them is also unclear and not always standardized (especially on the web).

I go through the ramifications of drinking untreated water, the language to use when researching and shopping for filtration and purification technologies, and the advantages and disadvantages of the various methods themselves.

The Risk and Consequences of Drinking Contaminated Water

Drinking untreated water can expose you to a variety of germs and parasites, which can cause disease if you consume them. What is the route through which these illnesses enter water sources? Humans and animals (as well as their waste) that hunt, live, bathe, defecate, and even die or have their remains dumped into lakes and rivers are frequently carriers of the disease, which may be found in both the wild and inhabited regions with inadequate sanitation methods. Giardiasis is a main waterborne infection that occurs in the wilderness areas of the United States.

Aside from cholera and dysentery, additional watery illnesses that may be found in the wilds of the globe include infections caused by various types of worms, viruses, and bacteria.

When you’re already dehydrated, whether it’s from a survival situation or simply from trekking for a few days straight, diarrhea can further worsen the situation and may even put your life in danger.

The only exception is if staying hydrated is absolutely necessary for your survival. If this is the case, untreated water should be consumed without hesitation. Dr. Giardiasis can be treated, but physicians cannot heal the dead, as is frequently stated in wilderness survival circles.

Does All Water Need to Be Treated?

Drinking untreated water can expose you to a variety of germs and parasites that can cause disease if you consume them. What is the route through which these illnesses enter water supplies. Humans and animals (as well as their waste) that hunt, live, bathe, defecate, and even die or have their remains dumped into lakes and rivers are frequently carriers of the disease in both the wild and in inhabited regions with inadequate sanitation procedures. Giardiasis is a main waterborne ailment that occurs in the wilderness areas of the United States of America.

  1. Another type of waterborne sickness found in the wilds of the globe is dysentery, which is caused by worms, viruses, and bacteria that can infect the digestive system.
  2. Having diarrhea would compound the dehydration you’ve already experienced in a survival situation or simply from trekking for a few days straight.
  3. Drinking water from the outdoors or from doubtful sources should be treated rather than taking the chance of contracting a severe infection.
  4. Untreated water should be consumed in this scenario.

Purification vs Filtration

It’s important to understand the difference between filtration and purification when it comes to water purification when it comes to locating and drinking water. They are not interchangeable terms. Water filtration is the process of removing trash and certain microorganisms from water by the use of a sieve, which is a sort of cloth or mesh net through which the water runs. Water purification is a procedure that uses chemicals or ultraviolet light to render bacteria and other hazardous agents inactive.

Sometimes water necessitates the use of both of these procedures, and other times it necessitates simply one.

In Africa, if you’re traveling and believe you’ll simply need a filter, you might wind up with a dangerous illness in your system, according to experts.

Water Filtration

Using a water filter, especially one that has been commercially tested (as opposed to the do-it-yourself backwoods kind), can effectively eradicate certain microorganisms. However, this is not the case. Filters may remove protozoa and bacteria from water, but they are unable to remove viruses that are present in the water because they are too tiny to be caught by the mesh of the filter. Water in the United States and Canada is generally considered safe for hiking and survival reasons when only filtration-only procedures and equipment are used; this is especially true in mountainous environments.

Water that has been filtered also has the best flavor.

The main fact is that while filters are excellent at removing pollutants from water — such as dirt and small germs — they are not totally successful at making water safe to drink. If it’s all you have, you’ll most likely be OK, but you should be aware that bad outcomes are still a possibility.

Water Purification

Water purification renders H2O safe to drink by deactivating any dangerous organisms, including viruses, that are present. Purification, on the other hand, does not completely eradicate pollutants. Filthy water that has been cleansed is still dirty water, and it is likely that it will require filtration (that should happen first, actually). Purification is accomplished largely by the use of boiling, chemical agents, or ultraviolet radiation. If you are traveling outside of first world nations, where viral illnesses are more frequent, you should take extra precautions.

Methods

You’ll find the most popular ways of water filtration and purification in the wild, as well as some of the advantages and disadvantages of each approach, listed here.

DIY Filters

In general, you should only utilize homemade filters if there is no other choice accessible to you. You certainly don’t want to go camping with the sole intention of filtering your water using pebbles, sand, and dirt. These are only for the purpose of survival. Although it is not necessary, it is advised that you continue to purify the water (either by boiling it, or by adding tablets or chemicals) after filtering it using these ways. I’ve arranged them in descending order of effectiveness, starting with the most effective at the top and ending with the least effective at the bottom.

  1. Despite the fact that this diagram contains a clamp, you are unlikely to find one in a wilderness survival situation.
  2. The most effective homemade water filtration system available is one that is constructed from a little piece of wood and tubing.
  3. Making this filter is as simple as cutting a tiny piece of sapwood (a couple of inches long by an inch or two wide) and wrapping it securely with some form of plastic tubing, if you have any on hand.
  4. If you don’t have plastic tubing, you may make due with alternative materials such as cordage, t-shirts/clothes, the plastic from a water bottle, and so forth.
  5. Keep in mind that this is a time-consuming approach, but you will be able to create up to 4 liters of filtered drinking water every day, which is more than enough for even a couple of people to drink from.
  6. It is traditional for campers to stack various materials in a hollow log or bag and then allow water to flow down from the top through the layers and out of a small hole at the bottom into a clean container.
  7. If you’re storing these goods in a bag, or even a tarp or a piece of fabric, make sure the bottom is closed off but has a small opening for water to trickle through.

After that, throw in some bigger boulders and a few chunks of charcoal (if you made a fire).

When you’re finished, it will have the appearance of a layer cake.

Shirt/Cloth.

Nonetheless, if that is what you are doing and if you are able to purify the solution afterwards, it is successful.

Simply placing muddy or unclean water in a container and allowing it to sit for around 12 hours will suffice.

The dirt and other debris will most likely sink to the bottom, leaving just clear water to float on top of the dirt and silt. This certainly has no effect on the removal of hazardous germs from the water, but it does make the water more pleasant to drink.

Commercial Filters

Straws for survival. A new generation of survival straws, the most well-known of which is the LifeStraw, has sprung into the market in the last 5 years or so. Drinking water directly via the straw (or water bottle with straw attached) is said to be safe due to the numerous filters that are housed within it, according to the concept behind it. The vast majority of straws available on the market are effective against bacteria and protozoa, but not against viruses. In most cases, they do not include any purifying agents.

  1. Just make sure to double-check the specifications to ensure they meet your requirements before making a purchase.
  2. This is not a good idea.
  3. Pump/Gravity Filter combination.
  4. In order to eradicate bigger infections, several people employ a ceramic filter, while others use silver to kill viruses.
  5. Gravity filters are more like IV bags in that they are slower to work but do not require batteries or human intervention.
  6. It doesn’t matter what circumstance you’re in as long as it mentions a purifying ingredient.
  7. These commercial filters are frequently larger and thicker than alternative solutions, requiring more room in a backpack or survival kit than they would otherwise require.

Boiling

Water purification in the backcountry is often accomplished by the use of boiling water. According to the Environmental Protection Agency, one minute of rolling boil will destroy all harmful organisms, including viruses. The duration is increased to 3 minutes if you are at a high altitude (more than 5,000 feet). Any metal or glass container will suffice, but if you don’t have any of those materials on hand, you may melt pebbles over a fire and set them in your container instead. When boiling water, one of the drawbacks is that it necessitates the use of a fire and consequently fuel, which is not always accessible (although it is more feasible if you read our article on how to start a fire without matches).

As a side effect, it causes some water to evaporate and a little amount of water to be lost, which should be taken into consideration in situations where every drop counts.

Chemical (Iodine/Chlorine/Bleach)

Iodine and chlorine are two widely used chemical treatments for treating water that make use of drops or tablets to disinfect and remove harmful contaminants: iodine and chlorine. Bleach is a third alternative for chemical cleansing, and it is most commonly used in more urban settings because it is more commonly found in the house rather than being taken as a wilderness survival item. Iodine. Use a 2 percent tincture and 5 drops per quart of water to achieve the desired effect. If the water is murky, add 10 drops of dishwashing liquid.

  1. Iodine is available in a little, relatively portable container and may be used for a variety of other things, such as treating wounds and warts.
  2. Iodine will impart a bitter flavor to food and is not recommended for pregnant women or people who are allergic to shellfish.
  3. Iodine is often the least expensive of the chemical procedures, and it is also the fastest.
  4. Chlorine.
  5. Water will be safe to drink and free of any hazardous microorganisms after about 4 hours of treatment time.
  6. On the plus side, most of the chlorine evaporates in that 4-hour period, resulting in a less noticeable change in the flavor of the water.
  7. Bleach.
  8. The majority of bleaches make use of sodium hypochlorite, which is a kind of liquid chlorine.
  9. Keep in mind that most household varieties will include 5-8 percent sodium hypochlorite — always double-check the label before using and avoid using it if the percentage is more than that.

UV/Solar

SODIS. Solar water disinfection (SODIS) is a technique that uses the power of the sun to disinfect water and make it safe to drink. Believe it or not, if you have a transparent water bottle, you can simply leave it in direct sunshine for 12 hours (24-48 hours on overcast days), and the sun’s ultraviolet rays will destroy the majority (but not all) of the bacteria and microbes in it. Some experts recommend leaving water exposed for a full day regardless of the circumstances, simply to be on the safe side.

Because this specific ultraviolet (UV) approach does not necessarily eliminate all germs and viruses, it is best utilized for survival purposes only, or in regions where water is known to be safe (or at least safe-ish).

There are a variety of gadgets available that generate UV light artificially in order to kill germs and even viruses in the home.

Always remember that because these aren’t filtration systems, bigger particles or debris in the water will not be removed, and some of those larger particles may contain diseases.

As a result, while employing the UV technique, it is recommended that the water be filtered beforehand. These devices, like pumps and filters, are bulkier and heavier than some of the other alternatives.

Bottom Line: What’s the Best Method for Various Scenarios?

For hikers and backpackers in first world countries: As previously stated, groundwater in regions such as the United States and Canada is virtually completely devoid of pathogens. This means that commercial filtration devices, even ones that do not cleanse (such as survival straws), will nearly always be sufficient to the task at hand in the majority of cases. The likelihood of contracting a virus in one of these situations is quite low. But because filters are often bigger and heavier than other options, chemical treatments are becoming increasingly popular, particularly among those who backpack or travel long distances through wilderness areas (like the Appalachian Trail).

  1. Tablets, UV devices, and filters that contain a purifying element fall into this category.
  2. For wilderness survival scenarios: You’ve become stuck in the wilderness for whatever reason, and you’re in desperate need of water to remain hydrated.
  3. If you have adequate water and fire available, boiling should be your first choice if you have the resources.
  4. And if you are unable to do so, a multilayer filter made of natural materials will be your best option for preventing disease.
  5. In conclusion, as has previously been stated, although it needs repeating, it is always preferable to drink untreated water rather than risk dying in the outdoors.

How to purify water in the wild

In North America, there are just a few of areas where you may safely drink water from a lake or stream. It’s recommended to bring your own water unless you’re camping in an area where clean drinking water is readily available. Water, on the other hand, weighs around 8 pounds per gallon and may be a big burden if you have to transport it a long distance. The option is to use less energy and purify what you need to use less of. Check out all of the different ways listed here and choose the one that works best for your style of vacation, the geographic region you will be visiting, and the amount of people in your party.

  1. For heights less than 6,600 feet, the Environmental Protection Agency advises a one-minute rolling boil, while for higher elevations, the agency suggests a three-minute rolling boil.
  2. Chlorine bleach or iodine can destroy the vast majority of waterborne microorganisms, but if the dosage is incorrect, they can be extremely harmful.
  3. Tablets containing chlorine dioxide and sodium dichloroisocyanurate are more efficient against giardia than tablets containing chlorine or iodine.
  4. The following are some disadvantages of utilizing water-treatment tablets: If the water temperature is higher than 68 degrees, they will need at least 30 minutes to complete their task.
  5. Heat accelerates chemical processes, so placing your water in the sun while the tablets are working will reduce the amount of time it takes to purify it.
  6. Additionally, aerating your water by pouring it back and forth between two canteens will help to lessen the bitter flavor following treatment.
  7. Filters remove microorganisms from the water, but they do not kill them.

A filter should be able to eliminate even the tiniest infectious organisms.

The tiniest holes allow viruses to pass through, however after filtering the water, water treatment tablets can kill the viruses.

This is due to the fact that the “bugs” become caught within the filter, which might ultimately become clogged and require cleaning or replacement.

They are more imposing than pumps, but they are as effective and less difficult to use – which is especially important when working with groups of Scouts.

Purifiers, on the other hand, often employ microfiltration in conjunction with either chemical treatment or UV radiation to destroy microorganisms, including viruses, in the water.

Ultraviolet Purifiers are used to purify water.

The well-known SteriPen was one of the first products to make advantage of this technology for usage in the outdoors.

It is safe to consume the water when the light shuts off (which takes around one minute).

However, they will not remove sediment or function well in hazy water.

Before you go, consider the following: Don’t overextend yourself by purchasing more protection than you require.

Discovering the many sorts of water sources accessible will enable you to select the system that is most appropriate for your requirements.

Your best option will be determined by the bacteria you anticipate encountering, the distance light needs to travel, and the volume of water you intend to treat. Guidelines for Handling H2O

  • Utilize a cotton cloth or a coffee filter to drain out any sediment before filtering or purifying
  • Algae in greenish water serve as a breeding ground for microorganisms. Algae can clog water filters and impair the efficacy of chemical disinfectants and cleaners. Brownish water includes organic tree tannins that are generally considered to be safe to consume. Beavers are Giardia’s preferred host, and they are found all over the world. Take care not to drink water from beaver streams or from areas near beaver lodges. Do not collect water from shallows or in close proximity to campers. Try to stay away from pure water that is pouring over sunlit rocks. While UV light is effective in killing bacteria, moving water mixes them together and increases the likelihood that they will enter your water sample. Take water from the surface of a calm, sunny pool that is near the surface. The majority of harmful creatures prefer to hide in the shadows, away from the light.
