Abstract:

The aim of this study was to evaluate the quality of freshwater resources of Balkan Arboretum Area located in Trakya University (Güllapoğlu Stream, Artificial Pond and Güllapoğlu Well) by a statistical approach using Pearson Correlation Index (PCI), Factor Analysis (FA) and Cluster Analysis (CA). For this purpose, total of 9 water quality parameters (dissolved oxygen, temperature, conductivity, pH, nitrate, nitrite, phosphate, sulphate and cyanide) were measured in water samples, which were collected monthly from 5 stations between the dates of June 2013 – October 2013. According to results of PCI, significant relations were recorded between temperature – nitrate and nitrate – sulphate parameters (p<0.01). According to results of FA, 2 factors named as "Agricultural Factor" and "Climatic Factor" explained 56.66% of the total variance. According to CA, 3 statistically significant clusters were formed, which were corresponded to Lentic and Lotic 1; Lotic 2 and Lotic 3; and Well stations.
