The team obtained and tested an online nitrite and ammonia analyzer at a potable water reservoir and interfaced the analyzers with the existing Supervisory Control and Data Acquisition (SCADA) system used by IRWD. These analyzers are being considered for use by IRWD for early detection of nitrification of chloraminated water in the reservoirs, which can lead to rapid bacterial growth and potential coliform outbreaks. Online nitrite and ammonia analysis is a new approach to enhance water quality monitoring and improve reservoir management practices to prevent and reverse nitrification.
