تقييم الوضع المائي في المنطقة الممتدة من ساحل البحر بمدينة صبراتة إلى منطقة عقار

الملخص EN

This study was conducted to the area of Sabrata.

The study is to assess the water situation in the area extending from the north sea coast to the southern region by taking a longitudinal sector estimated to be about 20 km long and 2 km wide.

A number of wells in the studied area were surveyed in the total of 39 wells selected randomly in different depths.

The most important analysis were the chemical and biological as well as statistical analysis, all are based on the field and laboratory data carried out on the samples compared with Libyan specification standard No.

82 of 2013.

In terms of chemical or biological content, as well as the classification of irrigation water according to the classification of the US Salinity Laboratory 1954.

The most important chemical analysis conducted Total Dissolved Salts (TDS), calcium ion (Ca++), magnesium ion (Mg++), sodium ion(Na++),(SAR),residual carbonate (RSC) and modified adjuvant sodium (adj-SAR) ratio, and the analysis of sodium chloride (K-), chloride ions, sulphate ions, bicarbonate ion and (NO-3), (Coliform bacteria), and bacteria (Escherichia coli).

After obtaining the results from the previous analyzes and discussing and represent them graphically, whether in the form of maps or other forms of graphical access to logical and scientific analysis of those results found that all the wells of the study area is not suitable for drinking either the total dissolved salts or other reasons for example the total dissolved salts higher It is permissible for several reasons that differ from one well to another, whether the cause is sea water intrusion, geological structure, gravity or other causes.

Biological pollution results indicated that most of the wells are biologically polluted due to the potential contamination of wastewater.

The wells are suitable only for irrigation of some crops that tolerate high salinity due to the high content of sodium or high salinity.
