Abstract

The purpose of this experiment was to compare levels of phosphorus and total dissolved solids (TDS) in city water and well water. It was hypothesized that well water would have higher levels of phosphorus and TDS, because well water is not treated but is pumped directly from the ground to pipes. Water samples were collected from city sources and well sources from the Columbia SC area in 40 mL vials. The phosphorus test relied on color to determine the amount present in the water sample, while TDS were measured using a digital tester. The data partially rejected the hypothesis, with the statistical analysis showing a statistically significant difference in phosphorus levels and a very slight significant difference in TDS levels, with city water having higher levels of both.
