300 contaminants in our water tables - datasets of threshold values and measurements (2016-2023)
Description
Le Monde publishes the datasets produced as part of its survey ["300 contaminants in our water tables: polluting by pollutant, our analysis of groundwater in France"](https://www.lemonde.fr/les-decodeurs/visuel/2024/05/15/300-contaminants-dans-nos-nappes-polluant-par-our-analyse-des-eaux-souterraines-en-france_6233361_4355770.html).
You will find three datasets in csv format:
- ````list_contaminants```` : the 300 parameters we analysed, with their typology by family of use and their threshold value if applicable.
- ````dataset_map``` : aggregated data for [our mapping](https://www.lemonde.fr/les-decodeurs/article/2024/05/15/explorez-our-carte-inedite-de-la-pollution-des-eaux-souterraines-en-france_6233388_4355770.html) of groundwater pollution in France.
- ````dataset_whole```` : all our data (parameters sought, quantifications, exceedances of threshold values, measurements, dates ...)
Ces données sont librement réutilisables à condition de faire référence au Monde et à [cette page](https://www.lemonde.fr/les-decodeurs/article/2024/05/15/comment-le-monde-a-cartographie-la-pollution-des-eaux-souterraines_6233362_4355770.html), et de nous en informer aux adresses sanchez[@]lemonde[.]fr et aubert[@]lemonde[.]fr.
Our analyses cover the period 2016-2023 (inclusive), for nearly 24700 control stations spread over the entire French territory. They are the result of a data extraction carried out on the [Groundwater Data Access Portal] (https://ades.eaufrance.fr/) on 16 April 2023.
Our methodology [is available here](https://www.lemonde.fr/les-decodeurs/article/2024/05/15/comment-le-monde-a-cartographie-la-pollution-des-eaux-souterraines_6233362_4355770.html).
