I am trying to get at something here. There can be different pollutants and different causes but I am referring specifically to waste water treatment plants or sewage treatment plants which are along the coast or which possibly are non-existent because there is only primary treatment of effluent. In general, has Mr. O'Mahony encountered this as a recurring problem, a problem that he has identified of that type of pollution or causing problems within water?
