216 III. Introduction to Water Resources and Contamination

What is the limit for total dissolved solids (TDS) for
purified water?

7. a. What is the cost per liter for bottled water (give the
brand, size, and where purchased (vending machine, grocery,
etc.)? Convert if the bottle is not liter-sized)?

Has anything been added to the water after purification?

b. What is the definition for sterilized water? b. How does this compare in price (per liter) with tap

water in your city?

Has the bottle of water described above
been sterilized

(Check with the city or the instructor for tap water cost; 1
U.S. gallon = 3.78 liters)

What was the process used for sterilization?
