Also, don't forget the plastic chemical taste in your water from those pliable plastic one gallon jugs. Depending on the composition of the water container, chemicals may be leaching from the container into your water. If you are bottling your own water in jugs at a local water supply, you may be putting yourself at risk. Storage of water requires specific guidelines to prevent bacteria growth during storage. Containers should be sterilized prior to filling and contamination is easy during the filling process.
Direct light has an impact on the stored water as well as the room temperature.
There is no need to buy bottled water when you can get higher quality water at home with appropriate water treatment devices at a lower cost and greater convenience. Consult your health care professional regarding the applicability of any opinions or recommendations with respect to your personal medical requirements.
