Equipment

Keep in mind that equipment needs to be calibrated on a regular basis (depends on the equipment)

Open hardware water tester

Not tested, unknown what parameters it tests and how accurately.

Research

From a request to test well water (Vlaamse Milieu Maatschappij)

Original Dutch

The sample is taken from the tap in the kitchen
The sample is then tested in a laboratory on a number of parameters, namely:
1. Acidity (pH)
2. Total organic carbon (TOC)
3. Ammonium
4. Nitrates
5. Nitrites
6. Fluorides
7. Iron
8. Lead
9. Cadmium
10. Arsenic
11. Chrome
12. Mangane
13. Total viable (or bacterial) count
14. Total coli bacteria
15. E. coli
16. Intestinal enterococci
