دراسة بعض الخواص الكيميائية للمياه الجوفية في منطقة ضاهر(جادو) وعلاقتها بمياه الشرب والري

Abstract

The study was conducted on 9 wells in the Daher Jado area, distributed in the shape of a crescent, all of them located about 30 km from the foot of the mountain to the south. The water of the wells subject to the study was subjected to the following tests. Total dissolved salts (T.D.S) , PH, cations (K++, Mg2,Ca2+,Na) and anions (O3-,SO4-,HCO3-,CO3-2,Cl-). The results obtained also showed that the average total dissolved salts (TDS) for underground well samples is 2479 mg/L with a range ranging from (1859- 2998). Therefore, these wells are not suitable for drinking, because the permissible limit according to the Libyan standard specification is 1000 mg/L, and some models indicated their suitability for irrigation. in general, the results obtained indicated that the water is not suitable for drinking.
