This article discusses an online water quality monitoring system installed by the Wichita (Kansas) Water Utilities District. It consists of a number of online chemical monitors that are linked to remote communications for the detection of abnormal water quality shifts. Continuous chloramine monitoring units were fitted inline just prior to the first customer distribution point to ensure satisfactory residual disinfection. Online turbidity monitoring systems were also installed at each of the utility's 14 filtering points to provide real‐time filter‐efficiency data. The article discusses the technology involved in the JMAR BioSentry® water monitoring system that the Wichita Water Utilities District installed at two locations in its water distribution system. The system uses multi‐angle light scattering (MALS) to detect and classify microorganisms through continuous slip‐stream analysis. The MALS principle provides for the generation of a unique, species‐specific, light‐scattering pattern when a microorganism passes through the flow cell laser beam.
