Why Water Purification is Crucial
Contaminated water can harbor all sorts of germs, bacteria, protozoa, and viruses that can make you seriously ill. Boiling or treating your water is essential to avoid diseases such as cholera, dysentery, and typhoid. So, when in doubt, it’s always better to purify your water.
Identifying Different Types of Contaminants
Before you jump into the purification process, it’s important to understand the types of contaminants that could be present in your water supply.
Biological Contaminants
These include bacteria, viruses, and protozoa. These microorganisms can cause severe gastrointestinal issues.
Chemical Contaminants
Chemicals like pesticides, heavy metals, and industrial waste can also contaminate water sources. These contaminants are often odorless and tasteless but can be harmful.
Physical Contaminants
Physical contaminants include debris, dirt, or sediment that can make the water appear cloudy. While not inherently dangerous, they can harbor other contaminants.
Basic Methods for Water Purification
Let’s begin with a few simple and fundamental methods for purifying water in an emergency. These techniques require minimal resources and can be done virtually anywhere.
Boiling
Boiling is one of the oldest and most effective ways to purify water.
- Boil the Water: Bring the water to a rolling boil for at least one minute. At higher altitudes (above 6,500 feet), you should boil for three minutes.
- Cool and Store: Let the water cool before drinking. Store it in clean, covered containers.
Pros and Cons
| Pros | Cons |
|---|---|
| Kills bacteria and viruses | Requires fuel and heat source |
| Easy to do | Doesn’t remove chemicals or sediments |
Filtration
Using a physical filter can remove debris and some pathogens from your water.
- Find a Filter: Portable water filters are available, but in an emergency, you can use cloth or coffee filters to remove larger particles.
- Filter the Water: Pour the water through the filter into a clean container.
Pros and Cons
| Pros | Cons |
|---|---|
| Removes debris and some microorganisms | Does not kill viruses |
| Portable and easy to use | Some filters can be expensive |
Chemical Treatment
Using chemical tablets or drops can also purify your water.
- Choose the Right Chemical: Chlorine, iodine, and purification tablets are popular choices.
- Follow Instructions: Add the recommended amount to your water and let it sit for the required time (usually 30 minutes to 4 hours).
Pros and Cons
| Pros | Cons |
|---|---|
| Kills bacteria and viruses | Chemical taste |
| Lightweight and portable | Time-consuming |
Advanced Methods for Water Purification
If you find yourself with access to more resources or have planned ahead, advanced methods can offer more comprehensive purification.
UV Light Purification
Using UV light to purify water is effective and convenient.
- Obtain a UV Purifier: These devices use ultraviolet light to kill microorganisms.
- Follow Instructions: Place the UV purifier in the water and activate it for the recommended time.
Pros and Cons
| Pros | Cons |
|---|---|
| Kills bacteria, viruses, and protozoa | Requires batteries |
| No chemical taste | Cannot remove debris |
Distillation
Distilling water can remove both biological and chemical contaminants.
- Set Up Distillation Apparatus: This usually involves boiling water and collecting the steam in a clean container.
- Collect Purified Water: The steam condenses into pure water, leaving contaminants behind.
Pros and Cons
| Pros | Cons |
|---|---|
| Removes most contaminants | Requires equipment and heat |
| Produces very pure water | Time-consuming |
Gravity-Fed Filters
These are more complex filtration systems that use gravity to force water through multiple stages of filters.
- Set Up Filter System: Follow the manufacturer’s instructions to set up the system.
- Filter Water: Pour water into the top and let it filter down into a clean container.
Pros and Cons
| Pros | Cons |
|---|---|
| Removes bacteria, viruses, and debris | Bulky and not portable |
Improvised Water Purification Methods
In a pinch, you might need to improvise. Here are some methods you can use with items commonly found around your home.
Solar Disinfection (SODIS)
This method uses UV light from the sun to kill pathogens.
- Obtain a Clear Bottle: Use a clear plastic or glass bottle.
- Fill and Shake: Fill the bottle with water, cap it, and shake it vigorously to oxygenate.
- Place in Sunlight: Leave the bottle in direct sunlight for at least 6 hours.
Pros and Cons
| Pros | Cons |
|---|---|
| Simple and no additional resources needed | Weather dependent |
| Kills bacteria, viruses, and protozoa | Takes several hours |
Homemade Filters
In an emergency, you can make a simple filter using common household items.
- Gather Materials: Needs sand, charcoal, and a container.
- Layer Materials: Layer the materials in the container, with charcoal at the bottom, followed by sand.
- Filter Water: Pour water through the filter into another container.
Pros and Cons
| Pros | Cons |
|---|---|
| Easy to make with household items | Does not remove viruses |
| Removes debris and some bacteria | Not as effective as commercial filters |
Important Considerations
Purifying water is not foolproof, and there are several factors to consider to make sure you’re doing it right.
Source of Water
Always choose the cleanest water source available. Clear, running water is generally safer than still water.
Storage
Use clean containers for both untreated and treated water. Never store treated water in containers that were previously used for untreated water.
Consistency
Make sure to thoroughly treat all the water you intend to use. One misleading sip of contaminated water can result in illness.
Backup Plans
Always have a backup method for purifying water. If one system fails, another can save you.
Summary
Water purification is a crucial skill that everyone should understand, especially in emergency situations. From simple boiling to high-tech UV purifiers, there are options for every scenario and budget. Remember to always choose the cleanest water source possible, properly store treated water, and have backup methods ready.
Recap Table
Here’s a quick recap of the various water purification methods:
| Method | Pros | Cons |
|---|---|---|
| Boiling | Kills bacteria and viruses | Requires fuel and heat source |
| Filtration | Removes debris and some microorganisms | Does not kill viruses |
| Chemical Treatment | Kills bacteria and viruses | Chemical taste, time-consuming |

Prepare Ahead of Time
While these methods can help you in a pinch, being prepared ahead of time is always the best strategy. Consider investing in a portable water filter, chemical treatment tablets, or a UV purifier for your emergency kit. And don’t forget to learn and practice these methods so you’ll be prepared when you really need it.
Being prepared and knowing how to act can make all the difference in an emergency. With a bit of knowledge and some practice, you’ll be able to ensure that you always have access to safe, drinkable water.
