Dataset on wastewater quality monitoring with adsorption and reflectance spectroscopy in the UV/Vis range

This dataset was collected during a 25-week monitoring campaign designed to evaluate the performance of a novel hyperspectral imaging system compared to state-of-the-art UV/Vis sensors. The dataset consists of 5801 hyperspectral images of raw wastewater taken at a 30-minute resolution, as well as measurements of temperature, ammonium, flow, turbidity, pH, and UV-vis absorbance spectra taken at a 2-minute resolution. In addition, we collected 533 grab samples and analyzed them in the laboratory for conventional pollutants, including ammonium, total suspended solids, total nitrogen, dissolved organic carbon, and phosphates. Notably, we gathered 86 of these samples after four rain events and subsequently analyzed them for twenty organic chemicals, which provided valuable insights into the impact of wet weather on pollutant levels.
