This paper introduces some experiences with developing mobile phone demonstrator applications for water quality information management using the Google Android platform. The work presented is part of an EU research project named LENVIS (Localised ENVironmental and health Information Services for all). The applications are focused on delivery of water quality information related to outdoor bathing waters in two case study areas in the Netherlands. Both monitored and modelled water quality information is delivered via mobile phone applications that are integrated with web applications. The applications also have functionalities for collecting user feedback on bathing water quality from the field and integrating it with the information provided by the water management authorities. Initial test results of the applications with targeted user groups are also presented, which demonstrate the promising potential of this technology for water quality information management applications and they indicate potential use in other application areas.
