Kirkland Signature Water’s History

Costco gets their distilled water from the Rocky Mountains in Kirkland, California. Kirkland derives its water from the Cedar River Watershed from Puget Sound. International Bottled Association (IBWA) member DS Service manufactures Kirkland’s Signature water.

It is widely accepted that neither Costco nor Kirkland are engaged in the water industry. Nevertheless, the question remains: Is Kirkland’s branded bottled water worth its price and does it meet all safety regulations for water?

Researchers thoroughly analyzed Kirkland’s bottled water. Aeration and UV filtering purify naturally produced raw water gathered from the environment.

On top of that, “microbiological pollutants” often present in tap water are removed by osmosis and other types of water purification filtering. A demineralization procedure is then used to add minerals that our bodies need.

In addition, FDA-approved purifying procedures are meticulously adhered to. The Safe Water Act regulates both the FDA and the EPA. According to reports, specific components of clean water regulations are more stringent than others.

Finally, Kirkland’s distinctive water is safe for consumption. As a result, medical experts gave it a grade of A since it originates from a safe source and has passed many purification methods. Kirkland’s water has been tested and determined to be free of pollutants.

The quality of bottled water varies widely. It’s because they come from various sources, are filtered in different methods, and are supplemented with different minerals in varying quantities.

As a result, it is not easy to find mineral water that is safe and nutritious. In contrast, Kirkland water is derived from an approved location, is carefully filtered, and is guaranteed to contain all of the vital minerals that the human body requires.
