Evaluation of Ground Water Quality and Suitability for Irrigation Purposes in Alagilat Area, Libya
Journal Title: International Journal of Engineering and Science Invention - Year 2017, Vol 6, Issue 5
Abstract
The current study aims at evaluating the ground water quality in Alagilat area, Northwest Libya, for irrigation application. Sixty-fife samples were collected from ground water wells at different depths. The samples were analyzed for Ca2+, K + , Mg2+, Na+ , Cl- , HCO3 - , CO3 2- , SO4 -2 , NO3 - , EC, TDS and TH. For classification purpose, some chemical indices like EC, Sodium percent (SP), Sodium adsorption ratio (SAR), residual sodium carbonate (RSC), Permeability index (PI), Magnesium ratio (MR) and Kelly`s ratio (KR), were calculated. The results indicated that the 83.1% and 12.31 % of the samples EC level fall under doubtful and unsuitable category. This in turn implies to the importance of carrying out a pre-treatment and monitoring of the studied samples if they were to be utilized in irrigation. One option is to grow salt tolerant crops to overcome this issue. Regarding the remaining indices, the results showed that more than 95% of the samples were found to be within the safe limit and likely suitable for agricultural irrigation purposes.
