Conclusion
My predictions that the pH of the waters would be different was correct. The average pH of the houses were 7.34, 7.46, 7.21 while the average pH of the Artesian well was 7.96, showing that the pH of water is higher at the Artesian well. Another thing to notice is that house 2 had a significantly lower average pH then both tests at house 1. This is expected since the water for the houses is treated to have a neutral pH, while the Artesian well is straight from the ground. These results could be more accurate if more tests were done. Also the pH tester may have been incorrect in its readings.
