Hello Benoit

As well as the Palintest/Wagtech kits, Delagua kits (https://www.delagua.org/delagua_kits) should be able to cover most of the common field measurable parameters. I think all of their Bacteriological Kit's No 1, 2 & 3 all include conductivity meters so you can check the groundwater salinity. You would also be wise to add an Arsenic test kit as the other Martin suggests.

As James says if there is a risk of chemical contamination you can't beat lab analysis. Either full suite, or as directed by a water quality expert in the field. I'd suggest that you first test for conductivity (very quick and easy, no reagents needed once you have a meter). If your water is saline there is little point in proceeding with further tests on it if you are able to find a suitable non-saline alternative source. After salinity, I'd check for turbidity, pH & arsenic (and any other parameters that you have field tests for and know may be problematic) then if all looks good move on to the bacti checks. You can then send samples from your best source for lab analysis.

Kind regards

Martin
