Abstract
With many parameters by which water can be measured, it can be difficult to understand whether water is high quality or low quality. To solve this problem, many water quality indices have been developed over the last 60 years. The UNI Hydrology Lab uses the National Sanitation Foundation Water Quality Index (NSFWQI). This index provides a methodology by which Dissolved Oxygen, Fecal Coliform, pH, Biochemical Oxygen Demand, Temperature Change, Total Phosphate, Nitrate, Turbidity, and Total Solids can be combined to provide a single number indicative of the overall water quality. In previous years, when WQI calculations were needed, the bulk of the work was done either by hand, aligning rulers on printed NSF graphs or one at a time with online calculators. This process is extremely time and labor intensive. This project sought to make a high-volume calculator with which thousands of data could be calculated in a matter of minutes.
