This study is done to investigate the quality of water in Sodri in North of Kordfan and to see the effect of traditional mining on it’ s quality. Three samples of groundwater were collected according to standards methods:- One sample from the hafir and two samples from the wells. Samples were analyzed for physical and chemical parameters. A number of analytical techniques were used. Atomic Absorption Spectroscopy was used for quantification of elements namely iron, zinc, manganese and copper. Spectrometry was used for measuring nitrate and nitrite. Flame photometer was employed for analysis of sodium, potassium, calcium and magnesium.

The pH results were found to be 7.69, 7.89 and 8.19; the electric conductivity 250 µs/cm , 2400 µs /cm and 2500 µs /cm; the total dissolved solid 150 mg/l, 1445 mg/l and 1500 mg/l; nitrate mg/l, 74 mg/l and 230 mg/l; chloride 14 mg/l, 115 mg/l and 170 mg/l.The results were recorded for the major elements; sodium 39.12 ppm, 507.7 ppm and 539.6 ppm; potassium 19.89 ppm, 20.69 ppm and 47.82ppm; calcium 91.05 ppm, 110.4 ppm and126.3ppm; magnesium 0.046 ppm, 0.332 ppm and 44.33ppm.
