Dear Sir,
As a Dane living in Majorca I have just read a study from the World Wildlife Foundation - WWF regarding sewage from cruise ships in the Baltic.  
According to this study less than a third of the cruise ships in the Baltic use the on-land facilities to dispose of their raw sewage in the harbours they visit.
Instead the raw waste is dumped at sea during the night.
I doubt the case is any different in the Med but have not located any studies to confirm this.
If the cruise ships in the Med behave like they do in the Baltic, I find this very disturbing (and why wouldn’t they - the owners are mostly the same).
Many of the ships hold up to 5000+ passengers and 2000+ crew which is the same as towns on land, where sewage must be treated by law.
 However the dumping is legal as long as you are 12 NM from the coast and thus in ‘international waters’.
The Med is an enclosed sea like the Baltic but the frequency of cruise ships is much, much higher.
I hope this information could be a basis for an article or two once researched.
