Evaluation of Groundwater Quality and its Suitability for Drinking Purposes in the Seiyun Area, Hadramout, Yemen

Abstract

The present study evaluates the groundwater quality for drinking purposes and determines physicochemical characteristics of groundwater in the Seiyun in Hadramout. In order to investigate the water quality, sampling was done, the chemical parameters were analyzed, and water quality index was determined. The analyzed physicochemical parameters such as pH, electrical conductivity, total dissolved solids, calcium, magnesium, sodium, potassium, bicarbonate, carbonate, sulfate, chloride, nitrate, and fluoride are used to characterize the groundwater quality and its suitability for drinking uses Results showed the pH range of 7.5-7.78, TDS 624-450 mg/L, CaCO3 364-305 mg/L calcium 98-66.8 mg/L, magnesium 25- 43.7 mg/L, bicarbonate 415 -317 mg/L, chloride 124-190 mg/L, iron 0.03- 0.99 mg/L, Nitrate 3.4-9.3mg/L, sulphate 170-105 mg/L. Most of the physicochemical parameters of the samples were within acceptable limits for human consumption purposes recommended by the WHO standard.
