EFFECTS OF GUMUSHANE MUNICIPAL WASTEWATERS ON THE STREAM HARSIT WATER QUALITY, TURKEY

The aim of this study was to examine effect of municipal wastewaters of the city of Gumushane within the Eastern Black Sea Basin on the stream Harsit water quality. For this reason, a study was fortnightly conducted during the four seasons between March 2009 and February 2010. The water samples collected in three monitoring stations along the main branch of stream Harsit were analyzed for six parameters, nitrite-nitrogen (NO2--N), nitrate-nitrogen (NO3--N), ammonium-nitrogen (NH4+-N), total nitrogen (TN), orthophosphate phosphorus (o-PO43--P), chemical oxygen demand (COD), in laboratory. Four parameters, dissolved oxygen (DO), water temperature (T), pH, electrical conductivity (EC), were also determined in situ. According to the Turkish Water Pollution Control Regulation (TWPCR), the stream Har?it was classified and the obtained results were evaluated.
