The relationship between water quality characteristics and spectrum photometric properties of water was investigated. Different sample types were taken to conduct the study (well, river, wastewater and synthetic samples). Chemical properties of samples were tested in addition to the absorbance of filtered samples at a range of visible and UV wavelength (200-220-300) and (400-500-700-1000) ηm. The work showed that there are significant effects of the quality parameters on the absorbance at a selected wavelength i.e. for well samples; nitrate, sulfate and chloride can be estimated with an acceptable precision through the absorbance at selected wavelengths. Furthermore organic, Nitrate and Alkalinity in the wastewater can be estimated via the absorbance measuring at a selected wavelength for the filtered samples. The same way can be followed for river samples. Finally, this work may be beginning of new aspects of a water quality monitoring that brings a great benefits and easy ways to those working with this field in the site or even in the lab.
