I hate to say this but I am pretty sure that's how the have always done it on SXM and for fact many other islands. For years I have seen these septic trucks going to the island land fill to unload (no pun meant) and I guess it filters through the other trash and sand. SXM has many ecological and SXM Pride organizations that kinda watches over this type of thing. Maybe a few but MOST Resorts do NOT just dump in the ocean, most likely what you see came for one of them or the have there own septic septic systems like you see in the USA. Very sandy, it soaks away very fast. I am not that worried or alarmed. It will be interesting to see what GOV has to say if they reply.
