AN INVESTIGATION OF THE SURFACE AND GROUNDWATER POLLUTION LEVEL IN THE PORSUK BASIN

In this paper, the surface water and the groundwater of the Porsuk creek and its basin were studied in order to determine their pollution levels. The basin waters are commonly polluted by industrial, agricultural and domestic wastewaters. In order to determine the pollution levels, 20 different stations along the Porsuk creek and 20 wells close to the surface water sampling stations in the Porsuk basin were selected and seasonal surface water and groundwater samples were collected for 2 years. For thesurface waters, 18 parameters and for the groundwater, 15 parameters were analyzed. The results were compared with according to the Water Pollution Control regulation and international standards withoutconsidering seasonal variations. The surface water and the ground water of the Porsuk creek and Porsuk basin were found to be in the class of IV water quality.
