Abstract
Garyllis river basin is located south of Troodos mountain, adjacent to the wasteland at the area of Vati and is charged for nearly three decades with the disposal of solid and liquid waste.
Thus, the changes on the environment have a direct connection with human activities. Various techniques have been developed to monitor the magnitude of the pollution, with the collection and analysis of samples from specific locations playing an important part.
In this thesis, the geology, hydrologic characteristics and the pollution of Garyllis river basin from Vati wasteland area until Polemidia dam is studied. The surface waters and the pollutants are carried to the dam and as a result the aquifers are polluted too.
In total, 24 water samples were collected from five defined sampling locations through the watershed. On-site measurements and laboratory chemical analyses were used for ten physicochemical parameters to determine the pollution level of the area of interest.
The results were collected and analyzed with the appropriate diagrams to draw conclusions as to the quality of the surface waters and for the state of the pollution that expands around the landfill of Vati.
Based on the grading limits for surface waters established by the Republic of Cyprus, the majority of the parameters analyzed exceed the acceptable limits and in general the physicochemical condition of the surface waters in this basin is considered “bad”.
The degradation of water quality is intense and it is connected directly to the wasteland in Vati and its leachate, proven by the elevated recorded concentrations of ammonia, nitrate, nitrite and phosphate ions, high conductivity, chemical and biochemical oxygen demands in the positions downstream of the disposal site of sewage and garbage.
According to the Water Framework Directive 2000/60/EC, Cyprus should implement a series of monitoring and management programs to achieve at least “good” surface water status by 2015.
A complete study and protection of the Geo-environment includes monitoring evaluation and restoration, for maintaining a good quality of soil, water, flora, fauna and man-made environment from any kind of pollution and restore the balance between the physical chain of lifecycles.
