Rafael Olmedo and Luis Burillo, from the Spanish research institute INTA, invented the NEPA application to detect changes in electrochemical water quality indicators and also potential
sources of hazardous pollution. By using the extreme accuracy of EGNOS (European Geostationary Navigation Overlay Service), NEPA can help authorities to uncover illegal wastewater influx
in waterways, identifying both how harmful the pollution is and exactly where it flows into the waterway. This application won the ESA Special Prize in the European Satellite Navigation
Competition 2010.
