Investigation For Escherichia Coli In The Water Wells In The Northwest Region Of Syria

Abstract

 The importance of this research comes from being the first research conducted in the northern region of Syria to investigate the presence of contamination in well water with Escherichia coli bacteria and to know the extent to which well water matches the standard specifications. A total of 50 samples of well water were collected from the beginning of the third month of 2019 until the first month of 2020. The bacteriological analysis was carried out for these samples where the standard qualitative analysis of water was performed by the method of the most probable number on well water samples. The results showed the presence of contamination in well water with coliforms by 28% and the presence of E. coli contamination that grows at a temperature of °44.5 C and it was positive for the indole test by 18%.
