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

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 = Water from the faucet (tap water) will most likely be the unhealthiest and have the most contaminants because of the area I live at. While running some of the contaminated waters through the filters will result in better drinking water.

Table 1: Ammonia Test Results
Water Sample	Test Results (mg/L)
Tap Water	30mg/L
Dasani® Bottled Water	100 mg/L
Fiji® Bottled Water	60mg/L

Table 2: Chloride Test Results

Table 3: 4 in 1 Test Results
Water Sample	Total Alkalinity (mg/L)	Total Chlorine (mg/L)	Total Hardness (mg/L)
Tap Water	120mg/L	0mg/L	0mg/L
Dasani® Bottled Water	240mg/L	0.2 mg/L	0mg/L
Fiji® Bottled Water	180mg/L	0mg/L	0mg/L

Tap Water	50ppm
Dasani® Bottled Water	50ppm
Fiji® Bottled Water	50ppm

Table 5: Iron Test Results
Water Sample	Test Results (ppm)
Tap Water	0.15ppm
Dasani® Bottled Water	0.3ppm
Fiji® Bottled Water	0.15ppm

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 = I would most likely reject my hypothesis because I was only correct about the tap water. Living in the area that I live at in Florida, we have been told that some parts of the tap water is not always safe and it’s always better to go with bottle water.

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

Answer = If I am correct, the Dasani water would be the healthiest but the fiji water contains the better PH balance than the other two.

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 = I realized that all three of these waters have containments in it but it doesn’t mean that it could cause health problems.

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

Answer = I never did and still do not believe that bottled water is worth the price. However, I still only pay for it because we are recommended to not drink any of the tap water here.

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