Abstract

Water samples were collected from three different sites of the Biga Stream (Canakkale, Turkey) in the months of October 2007 - September 2008 for the analyzing of some physico-chemical and microbiological parameters of the stream. In the present investigation, the mean average value (mean +/- SD) of the stream temperature, dissolved oxygen (DO), biochemical oxygen demand (BOD(5)), pH, electrical conductivity (EC), total coliform (TC) and faecal coliform (FC) were noted as 15.533 +/- 0.199 degrees C, 8.332 +/- 0.253 mg/L, 136.60 +/- 2.51 mg/L, 7.5078 +/- 0.0427, 869.93 +/- 3.72 mu S/cm, 39381 +/- 7952 MPN/100 mL and 42500 +/- 7072 MPN/100 mL, respectively. Based on results of comparison of data with WPCR, it is seen that waters of Biga Stream at the sites 1, 2 and 3 belonged to Class 4, for parameter BOD5 and faecal coliform and belonged to Class 3 for parameter total coliform. We conclude that there is a great potential risk of infection of waters from the Biga Stream.
