Who actually makes Kirkland water products?
ABC’s June 2015 report refers to Niagara-bottled Kirkland water. A July 2024 complaint names Costco and Niagara in relation to 16.9-ounce purified water; its allegations are not a court finding or an exclusive current supply contract. [3][2]
Where are Kirkland water products made?
These records do not allocate every Kirkland purified, spring, mineral or sparkling-water product to a plant. The Pennsylvania plants discussed in the 2015 recall story must not be assigned to Kirkland: that story explicitly excluded Kirkland from the recall. [3][2]
Is Kirkland water made in China or the USA?
No blanket US-only or China-made claim is established for every Kirkland water product. Identify the water type, market, bottler and package code before making a country or plant claim. [1][2]
Same factory, different label
Sharing a bottler would not establish the same water source or mineral content. Purified water in the 2024 complaint is a specific product, rather than evidence that every Costco water is the same as another store brand. [2]
