Excitation-emission spectra from raw wastewater and stream samples

Example excitation-emission spectra from analysis of raw wastewater and stream samples using a laboratory-based instrument. Differences in the response shown in these graphs illustrates differences in the optical properties of water from these two sources that can potentially be used to develop field sensors for detection of wastewater contamination in in environmental waters.
