Experiment 3: Drinking Water Quality

Bottled water is a billion dollar industry within the United States alone. Still, few people know the health benefits, if any, 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 water and a few types of bottled water to determine if there are health benefits in drinking bottled water.

  1. Label three 250mL beakers Tap Water, Dasani and Fiji. Pour 100 mL of the each type of water into the corresponding beakers.
      Ammonia Test Strip
  2. Locate the ammonia test strips. Begin by placing the test strip into the tap water sample and vigorously moving the strip up and down in the water for 30 seconds, making sure that the pads on the test strip are always submerged.
  3. Remove the test strip from the water and shake off the excess water.
  4. Hold the test strip level, with the pad side up, for 30 seconds.
  5. Read the results by turning the test strip so the pads are facing away from you. Compare the color of the small pad to the color chart at the end of the lab. Record your results in Table 2 .
  6. Repeat the procedure for both Dasani and Fiji Bottled Water. Record your results for both in Table 2.
