Assessment Of Some Physicochemical And Biological Characteristics Of Spring Water In Al Qayqab, Libya

الملخص

Drinking water to be consumed safely should be qualified by applying physical, chemical, and biological tests on a routine basis. This study aims to evaluate the portability of the water in both eastern and western springs in Al Qayqab ( El-Ghegab) town located in the eastern north of  Libya, by assessing some physic-chemical and microbiological parameters including; PH, Total dissolved solids (TDS), Turbidity, sodium (Na), and potassium(K); identify some heavy metals like Lead (Pb), Cadmium(Cd), Arsenic (As), and Mercury (Hg) and microbial contents including Total coliform count (TCC) and E coli as indicating to sewage pollution and comparing with guideline standards set by WHO and identify the differences in characteristics between the two spring. The analysis of selected samples at both eastern and western springs presented the average values of physical-chemical parameters; pH, turbidity, TDS, and K fall within the permissible limits set by WHO. Na means concentrations in both springs, eastern and western are 58.8 mg/l and 54 mg/l respectively, which slightly exceeded the permissible limits. We did not detect heavy metals of As, Cd, Pb, and Hg in all evaluated samples. The biological analysis detected total coli form and E coli in samples of the eastern spring indicating fecal contamination in this spring.
