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.

The water source I believe that will contain the most contaminants is Tap water due to the amount of chemical exposed in the water from pipes and other ground items . Fiji bottle water would be second and Dasani water being least contaminated .

2. Based on the results of your experiment, would accept or reject the hypothesis you produced in question 1? Explain how you determined this.

Accept/reject = After during the experiment I would reject my hypothesis I determine this because Dasani bottle water tested higher more likely contain contaminates. I was surprised because , I thought that pipes and sewers would more likely contaminate tap water than bottle water.

3. Based on the results of your experiment, what specific differences do you notice among the Dasani®, Fiji®, and Tap Water?

Answer = I notice that the tap water did not have any chlorine which poses a risk of being contaminated and making people sick. I noticed that the Fiji bottle water had 0mg/L of Alkalinity which poses a threat of being unsafe to drink. Based on the overall test results all three of the waters are safe to drink because the total hardness in each water source or type is between 0-50mg/L. Which meets the standards of safe drinking water .

4. Based upon the fact sheets provided (links at the end of this document), do any of these samples pose a health concern? Use evidence from the lab to support your answer.

Answer = Based on these samples tap water and Dasani concern because it’s PH levels are 5 and 6 . Fiji bottle water is safer to drink because the PH levels is 7 which is more safer than tap and Dasani .For the overall test results each water is Fiji bottle water have less contaminate than tap water and Dasani bottle of water .

5. Based on your results, do you believe that bottled water is worth the price? Use evidence from the lab to support your opinion.

Answer = Based on the test results , I don’t believe that bottle of water is worth the price .I learned a lot about bottle of water and tap water and believe that bottle of water had more contaminates than I originally expected. Tap water is not as bad as I thought though I will be drinking more tap water in the future.

**NOTE: Be sure to complete steps 1 - 32 of Lab 3, Experiment 1 (the next lab) before the end of this week. Lab 3 involves planting seeds, and if the work is not started this week, your plants will not have time to grow and the lab will not be finished on time.**
