Coastal marine environments are particularly exposed to pollutants emanating from human activities such as agriculture. Phytosanitary products follow the path of the water cycle, reaching rivers and aquifers, then coastal waters through run-off, infiltrations and resurgences. « OPALE » is an observatory dedicated to the monitoring of agricultural pollutions at the scale of the rivers Pérou-Père catchment area, located in Guadeloupe (Lesser Antilles). The main objectives of OPALE are to monitor and make available data on contamination levels and study the transfer of pollutants between the different aquatic compartments (surface waters, groundwaters and coastal waters).
