Abstract
The aim of the present study was to investigate the microbial contamination of Jamishan and Zemkan dams from July 2023 to June 2024. Sampling of Jamishan and Zemkan dams’s water was conducted every 45 days for one year. Searching, identifying, and enumerating the total coliforms and fecal coliforms’ counts was performed according to the method presented in the national standard. According to the results of the present study, the isolation of coliform and fecal coliform bacteria was observed in autumn and spring. The presence of these bacteria indicates fecal contamination of water. The results of the present study showed that fecal contamination due to animal husbandry activities as an important pollutant source in station 1 of Jamishan and Zemkan dams in autumn and spring. The lack of contamination with total coliforms and fecal coliforms in station 2 of Zemkan and Jamishan dams can be caused by the long distance of station 2 from the crest of the mentioned dams.
