I don't like the idea of product sellers also doing the testing. Given the current hiatus here, is there an independant lab in the West?
I got my water tested in UCHG. It's an independent lab at the back of the hospital beside the morgue. It cost 50 euro for the bacterial test and 25 euro for the mineral test. They have the bottles needed for both tests and they send out the findings in the post. The water treatment company I used recommended that I get the water checked myself first and that they would treat whatever it shows up.
