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 = I Believe that the water that will contain the most contaminants will be my tap water because I haven’t changed my water filters in over two years.

Water Sample	Test Results (mg/L)
Tap Water	0
Dasani® Bottled Water	0
Fiji® Bottled Water	0

Table 2: Chloride Test Results

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 reject the hypothesis bases on the results from my test samples.

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

Answer = I mostly noticed the PH levels we different in all three waters. Other than that Fuji had more phosphate and tap water had the most alkalinity and chlorine.

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 =

PH levels - Considering that “the EPA recommends that public water systems maintain pH levels of between 6.5 and 8.5,” and my tap water is 5 I am a bit concerned. The information tells me that ph below 7 means that acid is present in my water and the Dasani water. The effects can be staining my laundry, and sinks or damaging my water pipes over years. Drinking the water can lead to zinc and copper remnants being ingested.

Phosphate - According to our readings phosphate is not toxic to animals or humans unless found in large quantities.

Alkalinity- Helps keep the PH stabilized. If humans have an overload of Alkalinity their bodies can shut down because the body doesn’t need alkalinity at all to survive.

Chlorine - Reports show that drinking water with chlorine can increase the chances of bladder cancer.

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 do not believe that bottle water is worth the price. I will only buy spring water because what is the sense of buying filtered tap water but now I see that the spring water may the same as all the rest. My only issue with my tap water is that Radium 226 and 228 were reported in my tap water about three years ago so I had to install a three-stage water filter. Because of the water issue in the town, I would rather drink bottled water then my own tap water.

**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.**
