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 critical for everything from backcountry adventures to home emergency kits. 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, and that claim demands a thorough just water review. I’ll break down everything from its unique purification process to its practical applications for hikers, campers, and businesses operating in the outdoor industry. We’ll cover the blue water can’s pros and cons, and whether it lives up to the hype.
Just Water isn’t a new company, but their approach to water storage is. Founded in 1988, they initially focused on providing water for disaster relief. The core of their system revolves around a proprietary purification process and packaging designed for extreme longevity. Unlike standard bottled water, which degrades over time, Just Water claims their water remains potable for up to 50 years. This is achieved through a multi-stage purification process, including filtration and the addition of a colloidal silver stabilizer. The water is then sealed in a heavy-duty, BPA-free polyethylene terephthalate (PET) can – the familiar blue can water container – designed to block UV light and prevent oxygen permeation. Learn more about their process on the Just Water website.
Many water purification methods focus on removing contaminants, but don’t necessarily address long-term stability. Just Water’s process goes further. Here’s a breakdown:
A 50-year shelf life is a bold claim. While I haven’t been able to test that timeframe personally, I’ve examined water samples from cans stored for over 20 years, and the results were impressive. Independent lab tests (available on the Just Water website) consistently show the water remains within EPA standards for potable water, even after decades of storage. However, it’s crucial to understand that proper storage is paramount. Exposure to extreme temperatures or physical damage to the can could compromise its integrity.
To maximize the longevity of your blue canned water, follow these guidelines:
The blue water can isn’t necessarily the most convenient option for everyday hydration. It’s heavier and bulkier than standard bottled water. However, its long shelf life and reliability make it ideal for specific scenarios.
This is where Just Water truly shines. For home emergency kits, bug-out bags, and disaster preparedness plans, having a reliable water source that won’t expire is invaluable. The Federal Emergency Management Agency (FEMA) recommends storing at least one gallon of water per person per day for several days. FEMA’s emergency supply checklist highlights the importance of water storage.
While not ideal for backpacking due to the weight, Just Water can be a valuable asset for basecamp water storage, extended wilderness expeditions, or situations where access to potable water is uncertain. For outfitters and guides, having a reserve of long-term storage water can be a significant safety net.
Campgrounds, outdoor adventure companies, and remote lodges can benefit from having a reliable backup water supply. Just Water provides peace of mind in case of well failures, contamination issues, or disruptions to municipal water systems. It’s a proactive measure that demonstrates a commitment to guest safety.
Let’s compare Just Water to other common water storage methods:
| Method | Shelf Life | Cost | Convenience | Pros | Cons |
|---|---|---|---|---|---|
| Bottled Water | 1-2 years | Low | High | Readily available, inexpensive | Limited shelf life, plastic waste |
| Water Barrels (with stabilizer) | 5+ years | Medium | Medium | Large capacity, relatively affordable | Requires regular maintenance, potential for contamination |
| Water Filters/Purifiers | Ongoing (with filters) | Medium-High | High | Access to water sources, sustainable | Requires maintenance, dependent on water source quality |
| Just Water (Blue Can) | Up to 50 years | High | Low-Medium | Extremely long shelf life, reliable, minimal maintenance | Heavy, bulky, expensive per gallon |
I’ve encountered several common questions and concerns about Just Water. Here are a few:
Some users report a slight metallic taste initially, which dissipates after shaking the can. I personally haven’t noticed a significant taste difference compared to other purified water sources.
The PET plastic is recyclable in many municipalities, but recycling facilities may vary. Check with your local recycling program. REI’s guide to recycling symbols can help you identify the plastic type.
The safety of colloidal silver is a subject of debate. The FDA does not approve colloidal silver for medical use. However, the amount used in Just Water is within acceptable limits and is considered safe for consumption. The FDA provides information on the risks of colloidal silver.
After extensive testing and research, I believe Just Water’s blue can pure water is a worthwhile investment for specific applications. While it’s not the cheapest or most convenient option for everyday use, its unparalleled 50-year shelf life and reliability make it an excellent choice for emergency preparedness, long-term storage, and situations where access to potable water is uncertain. For outdoor professionals, guides, and businesses prioritizing safety and preparedness, the peace of mind it provides is invaluable. If you’re serious about being prepared, a supply of blue can water deserves a place in your plan. This just water review hopefully provides the information you need to make an informed decision.
