This study looks at the possible presence of total dissolved solids (TDS) in drinking water from various locations on a college campus and surrounding areas. Increased TDS levels can cause undesirable taste, odor, and color in water. Increased levels can also cause corrosion, staining, scale and sediments in plumbing and household fixtures. Water samples were taken from a local water treatment plant, local well water, a local creek and from buildings on campus. These samples were tested using a gravimetric method. The gravimetric method was chosen as it is able to measure anything that passes through a 2 μm pore sized filter while a TDS meter only measures the amount of ions in the water by measuring the conductivity. The TDS levels were then compared to national recommended limit provided in order to determine if the TDS levels in the water samples had undesirable properties.
