Thanks for the update on this. In all honesty there's only one place on earth that I had an issue with the tap water and that was Mexico. Montezuma's Revenge came to visit me for about 36 hours or so once. Last time in Mexico I took probiotics for one month prior to our vacation and for two weeks after we returned. For those who may be sensitive to tap water conditions that may be something worth trying on French St. Martin, or you can just drink bottled water instead. Been to SXM many, many times in the past and never had an issue with any water I consumed from any source.
