This API provides monitoring data on the quality of watercourses across the departmental network in Loire-Atlantique, France, published by the Département de Loire-Atlantique. It records physico-chemical parameters collected at monitoring stations since 2007, including ammonium, Kjeldahl nitrogen, organic carbon, chlorophyll a and chlorophyll a plus phaeopigments, chlorides, conductivity at 25°C, and related biochemical and demand-related indicators. The dataset supports tracking of surface water quality trends over time and can be used for environmental monitoring, research, and public information on river water conditions within the department.”Suivi de la qualité des cours d’eau sur le réseau départemental avec les informations sur les composants physico-chimiques depuis 2007 Les différents paramètres analysés sont : Ammonium Azote Kjeldahl Carbone Organique Chlorophylle a Chlorophylle a + phéopigments Chlorures Conductivité à 25°C Dem...
