The purpose of this investigation was to determine which sample offers the most balanced pH water, making it the most ideal for human consumption. Would it be bottled water or tap water? The hypothesis to be tested states that Nestle Pure Life bottled water would be the most balanced because of the purifying process used, and therefore, the most beneficial for human consumption. Ten tap water samples were collected from around my neighborhood, compared and tested for pH levels. Ten samples of three different brands of bottled water were also purchased and tested for pH levels. Data was recorded in logbook and analyzed. The Control sample was snow melt as it is the most naturally occurring water source. Three different methods for testing water pH were used and averaged for a more accurate analysis. The data was collected using pH test papers, a GO Direct Vernier pH probe, and a LaMotte pH chemical field test kit. Protocols for properly administering each test were carefully followed and results written in log book. The data did prove the hypothesis, although a much larger sample would have been more supportive.
