Abstract

The present study aimed at analyse a comprehensive descripton of physicochemical parameters and heavy metals in groundwater from Hajjah Governorate, Yemen: Six ground water samples were collected in the area of Hajjah city during the period from December (2017) to February (2018). Physicochemical parameters were analyzed (pH, temperature, EC, TDS, HCO3, SO4, NO3, total hardness, nitrogen and phosphorous, essential minerals and turbidity) which were important for water quality of groundwater. The heavy metal analyses of Cr, Zn, Fe, Co, Cu, Mn, Ni, and Cd, As, Cn, Al and Pb were performed for the water samples. The obtained results indicate a high significant differences in all Physicochemical parameters (p<0.001), except water temperature and ammonia among different water sources of Hajjah city (p>0.05). Concerning heavy metals, results indicated very highly significant differences in the levels of iron, manganese and zinc among the studied water sources (p<0.001), but all of them did not exceed the permissible levels suggested by WHO/YAMSO. Hence great attention must be paid to drinking water systems in the area of Hajjah city. Because to improper management, overpumping can deplete groundwater aquifers and lower water table.
