The official trials were conducted the same way as the pre-trials; the same processes were followed. In the end, 75 commercial trials were conducted. The commercial apples were bought from Yates and Meijer. It may seem odd that Yates is classified as commercial, but not all of their apples are from their orchards. Often times places like Yates outsource to meet their demand. A total of 91 noncommercial apples were tested. The noncommercial apples were acquired from Mr. Grobbel (a local independent produce seller), and Farmer Rick (a friend of the researcher's family). Right away some differences in the trials could be seen. The commercial apples from Meijer had a waxy coating. This not only raised the TDS contamination in the water, but it also did not look appealing. However, some trials from Yates appeared to have little to no contamination at all. Examples of the commercial trials can be seen below. The non commercial apples were relatively consistent with the amount of dirt in the beaker. They also had no drastic change in appearance. Examples of the remnants left in the beaker are shown below.
