As someone who’s spent over a decade guiding trips and writing about outdoor preparedness, I’m constantly evaluating emergency water solutions. The question of long-term water storage is a big one, especially for those of us who venture into the backcountry or work in the outdoor industry. Recently, I’ve been putting Just Water, specifically their iconic blue can pure water, to the test. This isn’t your typical bottled water; it’s marketed with a 50 year water shelf life, which immediately piqued my interest. This just water review will cover everything from its production process and storage considerations to its practical applications for hikers, campers, and emergency preparedness kits. We’ll also look at the blue water can itself and whether it lives up to the hype.
What is Just Water and How is it Different?
Just Water isn’t new, but its resurgence in popularity, particularly among preppers and outdoor enthusiasts, is noteworthy. Originally developed for the US military, Just Water utilizes a unique process of purification and stabilization. Unlike standard bottled water, which degrades over time, Just Water claims to maintain its purity and potability for up to 50 years thanks to its proprietary stabilization process. This process, according to the company, involves rigorous filtration and the addition of a food-grade stabilizer to prevent bacterial growth and maintain pH balance. The water source is spring water from a protected aquifer, adding to its initial purity. The blue canned water packaging is also a key component, designed to protect the water from light and oxygen, further contributing to its longevity.
The Science Behind the 50-Year Shelf Life
The claim of a 50-year shelf life is, understandably, met with skepticism. However, Just Water has undergone independent testing to support this claim. The company cites testing conducted by independent laboratories, demonstrating the water’s stability over extended periods. Their website details some of this testing. It’s important to note that this shelf life is contingent upon proper storage (more on that later). The stabilizer used is reportedly a food-grade mineral, and while the exact composition isn’t publicly disclosed, it’s considered safe for long-term consumption. For a deeper dive into water purification methods, the EPA’s Safe Drinking Water Act provides a comprehensive overview.
Testing the Blue Can: Practical Applications & Performance
I’ve been testing the blue can pure water in a variety of scenarios, from storing it in my emergency kit to taking it on multi-day backpacking trips. Here’s what I’ve found:
- Taste: The water tastes…clean. It doesn’t have the crisp, refreshing taste of some spring waters, but it’s perfectly palatable. There’s a very subtle mineral taste, likely from the stabilizer, but it’s not unpleasant.
- Weight: The cans are significantly heavier than plastic water bottles of the same volume. This is a major consideration for backpacking. A single gallon can weighs over 8 pounds.
- Durability: The steel can is incredibly durable. I’ve dropped it, kicked it (accidentally, of course!), and it’s held up remarkably well. This is a huge advantage over plastic bottles, which can easily puncture or crack.
- Emergency Preparedness: This is where Just Water truly shines. Knowing I have a reliable water source with a 50-year shelf life provides significant peace of mind. It’s a crucial component of any well-stocked emergency kit. The Ready.gov website offers excellent guidance on emergency water storage.
- Camping & Backcountry Use: While the weight is a drawback for backpacking, Just Water is a viable option for car camping or basecamp situations where weight isn’t a primary concern.
Storage Considerations for Maximum Longevity
The 50-year shelf life isn’t guaranteed; it depends heavily on proper storage. Here’s what Just Water recommends, and what I’ve found to be effective:
- Temperature: Store the cans in a cool, dry place. Avoid extreme temperatures and direct sunlight.
- Protection from Physical Damage: While the cans are durable, avoid stacking heavy objects on top of them.
- Avoid Freezing: Freezing can compromise the can and potentially affect the water’s stability.
- Original Packaging: Keep the cans in their original packaging to protect them from light.
I’ve been storing some cans in a basement with a consistent temperature of around 65°F, and others in a garage that experiences some temperature fluctuations. I plan to periodically test the water over the next few years to monitor its quality and verify the shelf life claims. The USDA Forest Service (fs.usda.gov) provides valuable information on water safety in outdoor environments.
Comparing Just Water to Other Emergency Water Options
Let’s look at how Just Water stacks up against other common emergency water solutions:
| Option | Shelf Life | Cost | Weight | Durability |
|---|---|---|---|---|
| Just Water (Blue Can) | Up to 50 years | High | Heavy | Excellent |
| Bottled Water (Plastic) | 1-2 years | Low | Light | Poor |
| Water Filter/Purifier | Indefinite (with filter replacement) | Medium | Light | Good |
| Water Storage Barrels | Up to 5 years (with treatment) | Medium | Very Heavy | Good |
As you can see, Just Water offers a unique combination of long shelf life and durability, but it comes at a higher cost and with increased weight. Water filters and purifiers are excellent for obtaining water in the field, but they require a water source. Water storage barrels are a good option for large-scale emergency storage, but they require regular maintenance and treatment.
Who is Just Water Best Suited For?
I believe Just Water is an excellent investment for several groups:
- Preppers & Emergency Preparedness Enthusiasts: The long shelf life and reliability make it a cornerstone of any comprehensive emergency plan.
- Outdoor Businesses (Guide Services, Campgrounds): Having a readily available, long-term water supply can be invaluable in emergency situations.
- Remote Cabin Owners: A reliable water source for extended stays off-grid.
- Individuals Living in Disaster-Prone Areas: Provides peace of mind in the face of potential disruptions to water supplies.
Addressing Common Concerns About the Blue Can Water
I’ve encountered several common questions and concerns about Just Water. Here are a few:
Is the Stabilizer Safe?
Yes, according to Just Water and independent testing, the stabilizer is a food-grade mineral and is considered safe for long-term consumption. However, individuals with specific dietary concerns or sensitivities should consult with a healthcare professional.
Is the Can Recyclable?
Yes, the steel can is fully recyclable. However, recycling facilities may vary, so check with your local provider.
Is it Worth the Price?
This is a subjective question. Just Water is significantly more expensive than other water options. However, the 50-year shelf life and durability justify the cost for those prioritizing long-term preparedness and reliability. Consider it an investment in peace of mind.
Final Thoughts on the Just Water Review
Overall, I’m impressed with Just Water. The blue can pure water delivers on its promise of long-term storage and durability. While the weight is a drawback for backpacking, its reliability and peace of mind make it a valuable addition to any emergency kit or preparedness plan. I’ll continue to monitor the water’s quality over time and provide updates. For more information on building a comprehensive emergency kit, check out my article on Essential Emergency Kit Items.
