Abstract

The purpose of this study was to test the effect of heat on the water quality within disposable plastic water bottles and to compare popular brands. The starting hypothesis was that Dasani would have the best quality water before and after heating at 55 and 76.6 degrees Celsius. To test the quality of the water, a Baldwin Meadows water test kit was purchased, which allowed for the testing of 14 different qualities of water. These were total alkalinity, pH, total hardness, iron, copper, bromine, lead, nitrite, nitrate, total chlorine, free chlorine, cyanuric acid, fluoride, and carbonate. After the procedures were conducted, the data was recorded and analyzed for final conclusion. Before heating at 55 degrees Celsius, the brands with the most to the least number of chemicals in the ideal range was as follows:1. Deer Park 2. Food Lion 3. Aquafina 4. Dasani. After being heated at 55 degrees Celsius, they were then ranked as: 1. Deer Park 2. Dasani 3. Aquafina/Food Lion. Before being heated at 76.6 degrees Celsius, the order was: 1. Deer Park 2. Food Lion 3. Dasani 4. Aquafina. After being heated at 76.6 degrees Celsius, the order was the same except for the switch of Dasani to #4 and Aquafina to #3. Overall, it can be concluded that Deer Park and Food Lion generally have the most number of chemicals in ideal ranges before and after heating with Aquafina and Dasani almost always at the bottom of the list.
