The lecturer discredits the claim in the reading passage that bottled water is better than tap water. First, she refutes the assertion that bottled water is healthier by pointing out that 40 percent of all water in bottles comes from city water sources. In other words, it is just tap water in a bottle. Furthermore, she contends that bottled water is actually less healthy than tap water because it contains a lower level of fluoride, a mineral that retards tooth decay.
Second, she maintains that minerals actually make the water taste better. Sodium, calcium, magnesium, and fluoride keep water from tasting flat. She backs up this statement by citing a taste test by Good Morning America in which 45 percent of the participants chose New York City tap water over bottled water.
Third, she concedes that it would be possible to recycle the plastic bottles used for bottled water, but she points out that only 15 percent of all water bottles are ever recycled, which means that 59. 5 million of the 70 million bottles used daily in the United States are thrown into landfills.
