Table 2 Summary of issues and responses

From: Feasibility and costs of water fluoridation in remote Australian Aboriginal communities

Issue Impact Response
Fluoride probes Under reporting of fluoride levels More reliable probes now standard in new plants
Fluoride bags partially undissolved Fluoride saturation and injection inhibited Mesh baskets to collect undissolved bags now standard in new plants
Fluoride scaling Fluoride saturation and injection inhibited Redesign of flow circulation to prevent scaling – now standard in new plants
Air in injection pumps Pumps cease operation Redesign of flow circulation to prevent air injection – now standard in new plants
Air conditioning in containers Environment uncomfortable and unsuitable temperature for instruments Future plants to be installed in more permanent structures which provide better insulation from heat
Fluoride concentration monitoring Ineffective system New supplier commissioned to install monitoring equipment
