A. Juice, milk, and soft drinks are almost all water, so they do count toward the required daily fluid intake. Nutritionists often recommend tap water because some beverages contain chemicals like caffeine and alcohol that do not help the body maintain fluid balance as well as other drinks. The spots that may appear on glassware after washing and air-drying are caused by nontoxic minerals that remain on the glass when the water evaporates. Spots on glass shower doors appear for the same reason.
Commercial products are available that allow the water to drain from glassware more completely.
A. Two reasons. First, this type of water storage ensures that water pressure and water volume are sufficient enough to fight fires, even if the electricity that normally pumps water is turned off. The second reason is to provide an extra source of drinking water during the day when water use is high. The water storage tanks are refilled at night when drinking water use is low. None of the chemicals or microbes that could make you sidk can be seen, tasted, or smelled.
