Abstract:
Sirte is a city that lies on the coast of the Mediterranean Sea being overwhelmed by the arid or the semi-arid climate. Across the extension of this city, there are several valleys descending from south to the north to be pouring into marshes across the long coast. The collected samples are subjected to different analyses, in order to conduct hydrochemical and bacteriological study of the study area, Chemical analyses have been conducted on those wells samples in terms of determining the concentration of main ions (Chloride Cl-, potassium K+, sodium Na+, sulfate SO42-, carbonate CO32-, bicarbonate HCO3--, Silicon Si4+, manganese Mn2+, Barium Ba2+, magnesium Mg2+, calcium Ca2+, nıtrate NO3-, NH4+, Alkalinity, electrical conductivity, acidity, pH and total dissolved solids TDS) and bacteriological analysis .For drinking, this groundwater are classified as very poor and unsuitable, furthermore, all analyzed samples for bacteriological content classified as contaminated and classified as unsafe too. Results showed that the concentration of (TDS) has been higher in wells. The increase in (TDS) in wells extending from south to the north, since (TDS) concentration and other ions were increasing the more we are coming close to the sea being a result of the sea waters' invasion. The study has come to the results that these waters are not suitable for drinking before treatment, because the rate of the total dissolved solids and ions are critically high. The wells ones which is an outcome of seawater leakage.
