Abstract

The present study aimed to evaluate some of microbial and
chemical qualities of water samples collected from three wells in SebhaLibya. The microbiological and chemical analysis were carried out on
water samples collected from three wells located at different Sebha
regions namely; El Thanawia well (ThW), Alminshia well (MW) and Al
korda well (KW). The microbiological analyses included heterotrophic
plate count (HPC), total coliform (TC), fecal coliform (FC), Escherichia
coli (EC) and fecal Streptococci (FS). Chemical analyses included
hydrogen ion concentration (pH), electrical conductivity (EC), total
dissolved solids (TDS) and total alkalinity. Results of this study
indicated that water of the three studied wells is not acceptable for
human drinking since the number of FS exceeds the permissible limit
recommended by WHO, however pH, EC, TDS and total alkalinity of all
collected samples were acceptable. Water of the three studied wells
should be treated against microbes contamination for human use with no
risk. It worthy to mention that water of the studied could be safety used
in irrigation of all crops.
