The City of Tucson Water Department presents real-time water quality information on their web site for use by the public and the press. City residents use the map-based interface to zoom in to their neighborhood, view the nearest distribution sampling point and details of its water quality, or view a summary of the water quality in their neighborhood or the whole city. The water quality information is updated daily, and results are posted for a dozen analytes the day after the data is collected. The intent of the project was to develop an interface that would allow utility personnel and consumers in the Tucson area to access data of high quality in near-real time. The initial requirements of the system included the ability to quality-assure data in an automated fashion using statistical methods, and a map-based interface that could access a database and perform aggregations and analysis upon request. The system was implemented using a customized ESRI ArcIMS interface for the map-based components. All of the data presentation is accomplished via Java servlets and applets on an IBM WebSphere Application Server accessing data from an Oracle database server. The system is designed to allow users to specify which analyte they wish to investigate from a list established by the utility. The utility specifies the period of record, how the data should be aggregated and also the data is presented (tabular, graphical or maps). This paper discusses the challenges encountered, solutions applied and applicability to other drinking water utilities. Includes figures.
