Abstract
Sanitary-bacteriological state of the Arpa and its tributary – Yeghegis rivers was assessed based on the bacteriological parameters (aerobic, coliform and Escherichia coli (E. coli) bacteria). Water sampling for the quantitative analysis of aerobic, coliform and E. coli bacteria was performed seasonally in May, July and November of 2016. The results of the study showed the deterioration of water sanitary-bacteriological state along the rivers. Fecal pollution degree in the midstream and downstream of the rivers may have posed serious pathogenic risks, in case of water used for recreational purposes.
