Lab 2 – Water Quality and Contamination Experiment 1: Drinking Water Quality Bottled water is a billion dollar industry in the United States. Still, few people know the health benefits, if any, that come from drinking bottled water as opposed to tap water. This experiment will look at the levels of a variety of different chemical compounds in both tap and bottled water to determine if there are health benefits in drinking bottled water. POST-LAB QUESTIONS 1. Develop a hypothesis regarding which water sources you believe will contain the most and least contaminants, and state why you believe this. Be sure to clearly rank all three sources from most to least contaminants. Hypothesis = I think that the Dasani water will contain the most contaminants because it goes through a chemical process to purify it. I think the Fiji water will also contain some contaminants but not as much as the Dasani because it is an all-natural water. I think that the tap water will contain the least amount of contaminants because it goes through a cleaning process over and over again.
