Datasets
The list of PFAS Known users was established manually by the FPP project using diverse sources. Methodological notes from the FPP project:
List of potential PFAS producers and users provided by Ian Cousins
Ian Cousins (Stockholm university) shared a research spreadsheet listing 108 potential producers and users in the world, including 25 in Europe.This list was the starting point to create a “Known PFAS users” category.
The list by INDITEX
The fashion group Inditex (Zara, Pull&Bear…) has developed a document named “The List by INDITEX” which classifies a dozen commercially available chemical families used for textile and leather manufacturing processes (such as dyestuffsor water & oils repellents), according to their level of compliance with Inditex’s own “product health standard” and “manufacturing restricted substance list”. Products including fluorocarbons are tagged with #7. We looked up fluorocarbon-containing products and included their manufacturers in our “PFAS know users” category.
Manufacturers of aqueous film-forming foams (AFFF)
We identified and located 23 type B (AFFF) firefighting foam manufacturing facilities using lists and information from the ECHA restriction report on firefighting foams, KEMI 2015, and IPEN 2018.
Google Maps
We entered the keyword “PTFE” in Google Maps and identified dozens of PTFE (Teflon) downstream users in Europe.
Serendipitous findings
Luck is part of research. Some locations were found by chance. For example, we were able to identify a few PFAS users while hovering over industrial zones and chemical parks in Google maps.

The European Pollutant Release and Transfer Register (EPRTR) lists most of the industrial sites in Europe. The FPP project used the list of activities established by Salvatore et al. (https://doi.org/10.1021/acs.estlett.2c00502) and transposed these into the NACE system to filter the sites of the EPRTR. The list of NACE codes used is in a csv file here: https://gitlab.com/pfas-data-hub/pdh-data/-/tree/main/data/raw/1__EPRTR/eprtr_nace.csv

The EEA provides a list of 21,488 WWTP in Europe. This data was filtered according to the methodology from Salvatore et al. (2022) This means it was filtered “to include only “major” WWTPs, which have a design flow of ≥1 million gallons per day or an industrial pretreatment program.” We filtered the dataset to include WWTPs which treat the equivalent quantity of water, i.e. a minimum 3,700 cubic metres per day. We used the field uwwWasteWaterTreated, but this is not very satisfactory since it is more or less filled in different countries. This excludes almost all italian WWTPs for example. If you know of a more clever way to proceed, please reach out to us. For France this field (uwwWasteWaterTreated) clearly has daily values instead of yearly ones, so we corrected the threshold accordingly.

The list of european facilities producing PFAS was established during the FPP, using OSINT techniques. A first list of 25 facilities was established, then each company was asked to comment before publication. The answers led to remove 5 locations from the list. From the remaining 20 facilities, 3 were no longer in use as of 2023 (indicated in an extra field "comments"). As far as we know this list was not established by anyone else, if you think there is a mistake please contact us.

In 2009, the French Agency for Food, Environmental and Occupational Health & Safety (Anses) conducted a monitoring
campaign of PFAS in drinking water. The locations were not made public. The FPP project obtained the full dataset
with de-anonymised locations through a "freedom of information" request.

To obtain or refresh the raw data:
go on https://www.elwasweb.nrw.de/elwas-web/index.xhtml Chose "Daten" > Oberflächengewässer > Auswertungen > Messstellen Chemie und Biologie Fachbereich: Chemie Auswertung: Einzelwerte Chemie, dann start
Messstellentyp: Fließgewässer (for dataset 48) Pick the widest time range possible Pick all Matrix Stoffgruppe: PFC, then Auswählen (this select all PFAS params) Pick all stations (Messstellen) click "Suchen"
you should see at least 26108 lines for fließgewässer (that was on 18/10/2024, the number should only go up), 1183 for stehende Gewässer
----- There is another CSV describing the params here: https://www.opengeodata.nrw.de/produkte/umwelt_klima/wasser/stoffliste/ We use it to add the cas id to the param names, so that they are recognised automatically during normalise.

The data was obtained by press request during the Forever Pollution Project Since they are all samplings in the output water of the Zentrale Abwasserbehandlungsanlage (ZARA) of the Gendorf Chemie Park, the same lat / lon was used for all points (loc was determined using Google Maps and a photo of the company website)
This dataset is for now disabled
The data was received as a printed report during FPP, then manually typed in a spreadsheet. The number format of the values is not the same on all lines, likely typing errors. I'm waiting for a image of the printed data to come back to the source and correct the data. (20/11/2024)Source

This dataset has an api in the Socrata format, so we use a dedicated python API that makes everything very simple. The data contains data about all substances, so we filter on the CAS_IDS that we have on our list. Strangely the PFNS is listed with cas_id 474511-07-4, which seems to be a mistake. We corrected it to 68259-12-1.

Water quality monitoring data from the UK Environment Agency. The data is updated from time to time. Some points have name of locations, some are marked redacted, in which case the localisation is rounded (easting and northings rounded before lat/lon are calculated).

Data form the UK Water Industry Research, from the program "Chemical Investigations Programme Phase 2" The data was manually downloaded from the WIR website (free account needed) I extracted one file per year 2015-2020, with no restrictions on substances, stations or companies. The data is then filtered on all parameter names that are in our synonym list.
We then proceed to 3 corrections: 1: The data has 1 location (Stoke St George) where the coordinates are in EPSG 27700 (all the rest being in lat / lon directly). 2: The data has various locations where for some rows, the lat or the lon is 0, although other rows at the same location have the values. We take the values from complete rows. 3: Olivia.Mair@defra.gov.uk sent us a correction request by email on 2023-02-23, so we manually correct the position of 1 water treatment plant.

This is data from the NRW , like datasets 47 and 48, but here the data is directly published via a CSV file. The CSV files come zipped, but in a weird way: the zipped and uncompressed files are the same size and I cannot automate the unzipping at all. For now, I just added the CSV files, but this is a bit sad, since it mean it wont update alone. I will try to contact them to solve it.
The data of the messtellen is available in a separate CSV. The coordinates are in UTM 32, with the last 2 digits often replaced by XX, not sure why (maybe safety reasons) I replaced these XX by 50: this is not perfect, but the difference is max 20 meters, so they still provide value on the map.

This data was given to us by the NGO Pesticide Action Network (PAN), who conducted their own study. Some lines had no coordinates and were removed. We don't have the precise date, but they confirmed the samplings were done in 2024.

Data from the drinking water monitoring from the Spanish Basque country (Euskadi). Data is freely available by download, only data from 2023 on has PFAS data. The X and Y coordinate are switched in their data, if at some point they correct it we will need to update the normaliser or the extractor.

The data is manually donwloaded from https://www.gkd.bayern.de/en/downloadcenter/wizard The GDK confirmed the data is updated once a year and there is no API. So we can update it manually once a year. Select all time period, individual values, then a program (multiple program fails, so one by one): Groudwater - chemie, Rivers - chemie (biota program), Rivers - chemie (water program), lakes -chemie we get 4 zips, 2 of them will uncompress in the same folder "fluesse - chemie", but that is not a problem. Once unzipped, The files are single files per sampling, which is as far as I know, unique among our data, but not hard to parse. Each file has 6 to 8 info lines, a blank line, then 2 data lines, one with headers, then with data, csv style. Some exceptions files have no data

Dataset 141 is about groundwater.
There is no API, it's a manual download, so it could be nice to update it from time to time.
Surprisingly, the lat and lon of the stations are not given in the download, but I found the data of all german
stations for groundwater here: https://umwelt.info/de/artikel/karte_grundwasser
I joined using the Messtelle-nummer and got almost all the data points.
