Data — Inventory Plaine d’Alsace quality 2009 — Measurement network

This layer includes all the points d' access of the Alsace plain to the tablecloth used during the measurement campaigns of “l' 2009 inventory of the quality of the water table of the plain of the Alsace” (M.O. Alsace Region) or 717 points. The coordinates of the measuring points are extracted from the basement bank (BRGM). They were checked and remedied with GPS by the collectors during the measurement campaign: In case of significant deviation, the coordinates have been re-checked by APRONA at #x27;GIS tools (Mapinfo, googlemap, geoportal) and if necessary by a field visit. L' maximum uncertainty on coordinates is 25 m. In 2013, an important task of updating the measurement network table was carried out. It was intended to verify that the points taken by the laboratories corresponded to the points originally planned during the preparation of the campaign. All uncertainties are lifted. The associated quality data relate to: — nitrates — chlorides — sulphates — ammonium — arsenic — Trichloroethylene and tetrachloroethylene — atrazine and its metabolites — plant protection products — the quality of the resource in the light of the common criteria of potability — drug residues — other parameters __Origin__ L' maximum uncertainty on the X and Y coordinates is 25 m. __Partner organisations__ APRONA, Alsace Region __Links annexes__ * [2009 inventory of groundwater quality in the plain of Alsace](http://www.region-alsace.eu/sites/default/files/fichiers/environnement/inv_2009_nappe_phr__atique.pdf) * [2009 Inventory of Groundwater Quality in Upper Rhine Fossé](http://www.region-alsace.eu/sites/default/files/fichiers/environnement/inv-2009-complet-light.pdf) * [open license "Etalab "](https://www.geograndest.fr/metadata/region-grand-est/DOCS/Licence-Ouverte-Open-Licence.pdf) [See this page on geo.data.gouv.fr](https://geo.data.gouv.fr/fr/datasets/f51807a8b8182cb7edf903a70227ea549cc50de3)
