Environmental concerns have led to increased scrutiny of bottled water packaging. Many companies now use recycled materials or offer more sustainable packaging options to address these issues.

The market continues to evolve, with new entrants and product innovations regularly emerging. Functional waters, enhanced with vitamins or electrolytes, represent a growing segment within the industry.

Sources of Kirkland Signature Water

Kirkland Signature water comes from two main sources: natural springs and purified municipal water. The brand offers both spring water and purified drinking water options to consumers.

Spring Water

Kirkland Signature spring water originates from natural springs in the Rocky Mountains. The water is collected directly from these mountain springs, preserving its natural mineral content. Costco partners with Niagara Bottling Company to bottle this spring water at facilities in California.

The spring water undergoes minimal processing to maintain its natural characteristics. It contains naturally occurring minerals that contribute to its taste profile. Kirkland Signature spring water is tested for quality and safety before bottling.

Purified Drinking Water

Kirkland Signature also offers purified drinking water. This water starts as municipal tap water from various locations. It then goes through a rigorous purification process that includes:

• Reverse osmosis filtration
• UV light treatment
• Ozonation
• Carbon filtration

The purification removes contaminants, chemicals, and other impurities. After filtration, the water is remineralized to enhance taste. This process adds back beneficial minerals like calcium and magnesium.

Niagara Bottling Company handles the purification and bottling of this water for Costco. The final product is tested to ensure it meets or exceeds FDA standards for purified water.

Filtration and Purification Process

Kirkland Signature water undergoes a comprehensive purification process to ensure high quality and safety. The multi-step system combines advanced technologies to remove impurities and enhance taste.

Filtration Procedure

Kirkland’s filtration begins with carbon filtration to remove chlorine, organic compounds, and odors. Activated carbon filters trap contaminants through adsorption, improving water taste and clarity. The water then passes through sediment filters to eliminate larger particles like sand and silt.

Microfiltration follows, using membrane filters with microscopic pores to catch bacteria and protozoa. This step significantly reduces the microbial load in the water. Ion exchange filters may also be employed to soften water by removing calcium and magnesium ions.

Reverse Osmosis

Reverse osmosis (RO) is a key component of Kirkland’s purification process. Water is forced through a semi-permeable membrane under high pressure. This membrane acts as a molecular sieve, allowing water molecules to pass through while blocking dissolved solids, heavy metals, and other contaminants.

RO can remove up to 99% of dissolved salts, particles, and microorganisms. The process effectively eliminates common pollutants like lead, arsenic, and nitrates. After RO, the water’s purity is significantly enhanced, though some minerals may be added back for taste.

UV Filtration

UV filtration serves as a final safeguard in Kirkland’s purification system. Water passes through a chamber with UV-C light, which disrupts the DNA of any remaining microorganisms. This process inactivates bacteria, viruses, and parasites without using chemicals or altering water taste.

UV treatment is particularly effective against chlorine-resistant pathogens like Giardia and Cryptosporidium. It provides an additional layer of protection, ensuring the water is microbiologically safe. The UV system is typically designed to deliver a specific dose, measured in millijoules per square centimeter, to achieve optimal disinfection.

Quality Assessment

Kirkland Signature bottled water undergoes rigorous quality control processes to ensure safety and purity. The brand adheres to strict standards and conducts comprehensive testing to deliver a reliable product to consumers.

Safety Standards and Regulations

Kirkland Signature water complies with the Safe Drinking Water Act, which sets legal limits for contaminants in drinking water. The brand follows FDA regulations for bottled water production and packaging.

Costco’s quality assurance team regularly audits bottling facilities to verify adherence to food safety protocols. These audits assess sanitation practices, equipment maintenance, and employee training programs.

The water undergoes multiple filtration steps, including reverse osmosis and UV light treatment. These processes remove impurities and eliminate potential pathogens, ensuring a clean and safe product.

Testing for Contaminants

Kirkland Signature water is tested for over 150 potential contaminants, including:

• Microorganisms (e.g. E. coli, coliform bacteria)
• Inorganic compounds (e.g. lead, arsenic)
• Organic chemicals (e.g. pesticides, herbicides)
• Radionuclides

The brand utilizes certified laboratories to conduct these tests. Results are regularly reviewed to maintain consistent water quality.
