Abstract

 The aim of this study was to investigate the microbial and physicochemical parameters of Neur Lake water. Five stations (studied stations according to geographical location, water elevation, flows to the lake) were selected. Sampling was done twice in year, once in spring and summer and Autumn 1395. The microbial tests were performed including counting the total number of bacteria, total Coliform and fecal coliform, Streptococcus and sulfite Reducing Bacteria. The highest density of Heterotrophic Bacteria was in summer and at station 1 (50, 000 cfu / ml). The highest levels of Fecal coliforms were at station 1 and 3 (110 cfu / ml) in autumn. The highest incidence of Streptococcus was at station 3 (110 cfu / ml) in summer. The highest frequency of sulfite reduction Bacteria was at station 1 in the spring at PO4mg / l, NH4mg / l and NO3mg / l in all seasons in the EPA standard. The COD, BOD and pH in some seasons were higher than the standard EPA standard The amount of Heterotrophic bacteria, total Coliform and streptococus in some seasons and stations was higher than the standard, due to the increase of environment and water temperature, Passing livestock in the region, and some tourist and agricultural activities in the warm seasons. Wind and water turbulence and sediment increase in the autumn were the causes of microbial contamination in Neur Lake. The lake is not desirable for fish species, especially cold water, due to the high parameters of physical and chemical properties of water.
