Drinking Water

Abstract

The assessment of drinking water quality is one of the main applications of UV-visible spectrophotometry. From the quality of resources to tap water, UV sensing is used for the characterisation of water resources (freshwater or groundwater) and drinking water even during rainfalls or floods, for water treatment assistance or as early warning system in case of accidental or intentional contamination. On the other hand, UV measurement is more and more considered as a surrogate parameter for the monitoring or the prediction of disinfection by-products. Finally, UV spectrophotometry remains a good tool for the chemical characterisation of drinking water either in the distribution system or packed in bottles.
