Frequently Asked Questions

Blue Can offers a 50-year shelf life guarantee for its pure water products based on state-of-the-art manufacturing processes that exceed standard FDA regulations and bottled water industry standards. FDA has established specific regulations for bottled water in Title 21 of the Code of Federal Regulations (21 CFR) that you can read here.

The International Bottled Water Association (IBWA) further adds:
The U.S. Food and Drug Administration, which regulates the quality and safety of bottled water, has neither set nor suggested any limitation to the shelf life of bottled water. In that regard, the International Bottled Water Association's general position is that as long as water is packaged in accordance with FDA processing and good manufacturing practices, 21 CFR, Part 129, and meets the FDA quality standard provisions as outlined in 21 CFR, Part 165, the product's shelf life should remain intact for an indefinite period provided that product storage is as recommended by the manufacturer.

How long does your water last?

What temperature do you recommend storing Blue Can?

Temperature fluctuations do not change the quality of our water. It's recommended water be stored between 33 degrees Fahrenheit (0 degrees Celsius) and no higher than 145 degrees (55 degrees Celsius) Fahrenheit for best results.

Is the water deionized?

BCW has an ORP of approx. 430, according to the FDA Certified Lab. Deionization is not required. BCW already has less than 1 ppm of dissolved solids.

What is the difference between your water and distilled water?

Distilled water has been de-mineralised, generally by evaporating the water and collecting the droplets. Additionally, the boiling point of most synthetic chemicals, including pesticides, herbicides, and chlorine solutions is lower than the boiling point of water. Synthetic chemicals are the major contaminants remaining after municipal treatment. Distillation does not remove these harmful chemicals.  Distilled water can also allow bacteria to rapidly grow when packaged as it is often not hermetically sealed in a container.  Blue Can water has the minerals removed by filtering to less than 1 parts per million. There are still minerals but they are only extremely small particulates. Additionally Blue Cangoes to great lengths to sterilize our water through UV light and Ozone flooding so that there is no bacteria or virus pathogens before we hermetically seal our cans.

What is the can liner made of?

In accordance with the FDA requirements, Blue Can Water cans have an epoxy coating on the inside to protect the contents from the metal. (Aged water in the can has been tested BPA-Free by an FDA certified lab).


Blue Can Pure Water is always at a neutral PH to prevent any decay of the epoxy coating inside the containers.

Is radiological testing conducted on the source water at least every 4 years? 

Radiological testing is done EVERY YEAR and no Radiological residue has been detected. Water analysis reports are performed by third party laboratories using procedures established by EPA, AOAC, APHA, AWW and WPCF.  Extensive testing was conducted by an independent analytical NELAP Accredited Laboratory  (Weck Laboratories Inc. ISO 17025, ELAP #1132, LACSD #10143, NELAC #04229CA) who certified that the test results meet all requirements of NELAC.  According to the certified lab report, BCW meets all drinking water standards as established by the State of California Department of Health Services.  Certificate of Analysis is available HERE.

Additionally, do you provide a guaranteed label or agreement on the shelf-life of the canned water?

I have an expensive home water filter system. How is Blue Can Water different?

Our water is filtered by the latest in modern technology multi-stage filtering and purification systems to ensure the cleanest water possible.

How long will the water last in the can?

50 Years if stored properly.

Does the water taste metallic?

NO, there is an epoxy coating inside and outside of the can to protect the water from the aluminum.

Is the water BPA Free?

YES, the water is lab-certified to be BPA-free.

How does the water hydrate your body faster than any other water?

We believe that the purity of our water  (less than 1 part per million (ppm) of particulates) contains smaller molecular H2O clusters. This allows the water to penetrate the stomach wall quickly, hydrating your body faster with no bloating.

We like our water at room temperature and in a glass, does it go flat after sitting in a glass?

How is Blue Can Water purified?

Blue Can filters and purifies canned water to less than one part per million of dissolved solids. During the canning process, each can of water is (patent pending) pressurised, removing all oxygen before hermetically sealing for long-term storage. This gives Blue Can products the unique advantage of protection from UV light and all other possible contaminants, making the expiration of the pure water inside a Blue Can proportional to the shelf life of the aluminium container itself. Unlike tin and steel, aluminium cans do not rust. Therefore, Blue Can offers a 50-Year Shelf Life for its pure water products based on state-of-the-art manufacturing processes that exceed standard FDA regulations and bottled water industry standards.

What makes Blue Can Water so different?

Firstly, it is in a can, not a plastic bottle.

Secondly, we use state-of-the-art filtering process to purify the water, making it taste clean and fresh for decades.

Can I cook with this water?

Yes, please do. It is great for making tea, coffee or soups. It is also great in protein shakes.

Why Aluminum Cans?

Aluminum is a sustainable metal and can be recycled over and over again. A can is generally turned into a new can and back on store shelves within 60 days. Cans are usually available through curbside pickup or community drop-off locations nationwide.

Questions about Aluminum Can

Why cans?

Cans chill faster, are colder to the touch on hot summer days, stack best, are the most recycled and recyclable container, are lightweight and volume efficient, maintains freshness, protects content from light, are tamper evident, have long shelf lives, are environmentally friendly, and are rigid and unbreakable. Cans protect their contents to ensure uniformity of product quality. 

Tin cans have been replaced by tin-free steel which is given a thin tin coating, usually as thin as a human hair, to prevent rusting. Protective coatings applied to the inside of the cans ensure the integrity of the contents and have allowed cans to hold many products, such as acidic fruits, which would otherwise be too corrosive. Technologies for both tin-free steel and aluminum have added even more flexibility and versatility to today's can.

Is a steel can the same as a tin can?

NO, its just like any water.
