Passover Kashrut alert on Water with added minerals
April 2, 2019 from COR Detroit: .
WATER: Any unflavored, spring or distilled or purified bottled water with no additives listed may be used. (Note: 3 and 5 gallon reusable containers should not be used for Pesach.) Water with added minerals (such as magnesium, potassium, calcium and sodium compounds), is generally acceptable if no flavors or vitamins are listed; e.g., Dasani and Nestle Pure Life brands of unflavored purified water. However, some brands, e.g., Kirkland Signature brand Purified Water with minerals added, list calcium citrate, which may be derived from chometz, and are not recommended
