DETECTION OF MICROBIAL CONTAMINATION IN COLLECTED RAINWATER IN GROUND RESERVOIRS BESIDE MAIN ROADS (ASBAYYA- GHARIAN- MAZDAH)

Abstract

This study is conducted to investigate the extent to which water was contaminated with colon bacteria in ground tanks that extend along the Asbayya-
Gharian and Gharyan- Mazdah roads. 20 samples were collected from the collected water pools in the ground reservoirs along the road and also 20 samples of water collected in ground reservoirs along the (Greian-Mazdah) between March and August. The samples were taken by sterilized glass bottles. The sterilized bottle was sealed in water, then, opened inside the tank to enter the water directly and prevent the possibility of external contamination. The samples were placed in the refrigerated case to prevent undergoing bacterial growth. The samples were taken to the laboratory for further investigation and defined for positive/negative samples containing colon bacteria. Statistical analysis of the study found that 20% of the water samples taken from the tanks along the Asbayya- Gharian road were not suitable for drinking, and 37% of the water samples from the Western Mountain Road area were not suitable for drinking. Because it contains a high percentage of colon bacteria.
