Sea water quality monitoring in Rhodes and Cos (Greece)

During the years 1983–1986, a program aiming at monitoring water quality of the most crowded beaches, as well as assessing and minimizing pollution from certain land based sources was carried out in Rhodes and Cos. The program was directed towards inspections of treatment plants as well as laboratory analyses of treated effluents from large hotels. As a result, almost one in four hotels was obliged to construct a new treatment plant. In order to help personnel to improve plant efficiency through day‐to‐day maintenance a three day seminar was held in June 1985. Sea water quality parameters (total coliforms and E. coli) were found to be well below the limits set by E.E.C. directives.
