My understanding is that the testing for bromates is relatively new. As a visitor who doesn’t cook, brushes my teeth with bottled water, and only drinks bottled water, I’m not concerned. As to French-side restaurants, who are only supposed to cook with bottled water, whether they do or don’t, I’m only there a few weeks a year.

St Barth, which also uses desalinated water, has been under a similar “temporary” ban since last August. If they can’t fix the problem in a hurry then I have less hope for St Martin.
