Quality data of rivers

Quality Data Archive The quality of water in the main rivers of the Adour-Garonne basin is regularly measured in networks established since 1971. This measuring device is based on: • Monitoring of chemical and biological status to ensure the good condition of watercourses • Operational controls to identify pollution that prevents the achievement of good condition and to monitor the evolution of watercourses following actions taken • Monitoring checks to ensure specific monitoring of protected areas such as catchments for drinking water or bathing A network of reference stations makes it possible to define the reference conditions for the different types of water bodies that can be considered in good ecological status. __Origin__ Measurements carried out in the framework of networks established since 1971 __Partner organisations__ Agency of l'eau Adour-Garonne __Links annexes__ * [data 2000-2005 in CSV format (20 MB)](http://adour-garonne.eaufrance.fr/upload/DATA/THEMATIQUES/QUALITE/donnees_qualite_2000_2005.zip) * [data 1990-1999 in CSV format (26 MB)](http://adour-garonne.eaufrance.fr/upload/DATA/THEMATIQUES/QUALITE/donnees_qualite_1990_1999.zip) * [data 1980-1989 in CSV format (24 MB)](http://adour-garonne.eaufrance.fr/upload/DATA/THEMATIQUES/QUALITE/donnees_qualite_1980_1989.zip) * [data 1971-1979 in CSV format (20 MB)](http://adour-garonne.eaufrance.fr/upload/DATA/THEMATIQUES/QUALITE/donnees_qualite_1971_1979.zip) * [archives 1971-2016 according to l' Decree of 27 July 2015](http://adour-garonne.eaufrance.fr/upload/DATA/THEMATIQUES/QUALITE/DCE-27JUL2015) [See this page on geo.data.gouv.fr](https://geo.data.gouv.fr/fr/datasets/5a3bfb08ce37de663133c8c19034231b4fc6d76c)
