Earth observation methodology possesses great potential to support water quality monitoring programmes, particularly in remote and inaccessible areas. However, thorough calibration of the associated algorithms is required to ensure reliable observations. GEO Aquawatch is an initiative which aims to establish and develop global applications of water quality data based on earth observation.

Water quality monitoring data are continuously collected in local, national and multinational databases, which need to be linked to provide information on a global scale. The OGC Water Quality Interoperability Experiment is testing the interoperability and connectivity of existing water quality platforms, using a framework developed from the OGC WaterML suite of standards, the OGC SensorThings API and the OGC standard on Observations, Measurements and Sample.

The World Water Quality Alliance (WWQA) is a global multi-stakeholder network. It promotes the recognition of the central role for freshwater quality to increase prosperity and sustainability worldwide. The alliance provides a cooperative platform for water quality assessment and the design of custom-made services driven by demands. Particular attention is given to the involvement of local communities and younger generations.
