Get in the boot with a torch and get someone to hose it from all angles,you might be lucky and see where it's coming from.
I think it's unusual for a 1999 model,,just a thought though,it might be that the boot lid isn't closing onto the seal fully,you can adjust it with the rubber posts by screwing them in a bit,,but this may also alter the locking position,,a bit of trial and error I'm afraid.
