The 18 L bottled water carboys should be dispensed through a refrigerated water cooler that is kept clean to avoid contamination (see Q18). Consumers can determine the freshness of the product by referring to the bottling date and best-before-date on the bottle.  more

To maintain the purity of bottled water, Health Canada recommends that you refrigerate the smaller bottled water once it is opened, and preferably once you buy it. The 18 L bottled water carboys should be dispensed through a refrigerated water cooler that is kept clean to avoid contamination (see Q.19) Check the bottling date and best-before-date on the bottle to determine how fresh the product is.
