| Abstract | ||
| An attempt was made to study Sawa Lake, Samawah, Al-Muthanna Governorate during the period from October, 2015 to September 2016. The objective was to determine the effect of the fluctuation of lake water levels on the fluctuation and quality of the surrounding groundwater. Monthly samples were taken from lake water, pizometers and a quarterly from other wells and aquatic eyes. Additionaly, samples of the lake water column at depths of 1 m, 3 m, 4 m and 13 m. Water level of the lake and the control wells corresponded to the water level of the lake and the water levels in the wells west of the lake were resembled. The results also showed variations in the values of EC, TDS, positive and negative ions between the water of the lake bed and the observation wells and the aquatic eyes. These differences were attributed to chemical analyzes of the surface water layer of the lake. The water pulled down in one part of the West Lake may be responsible for the movement of the water at the bottom of the lake and its rotation and the maintenance of the values of electrical conductivity is fixed to the depth of 1 m at the rate of 19.30 dm -1 despite the high evaporation conditions of a free water surface. The results also indicated a high concentration of boron and lead and a low concentration of nitrates and cadmium in the lake water. | ||
