| Abstract | ||||
| The present study is concerned with the chemical composition of water at twelve springs and wells selected from Ninevah district and adjacent area at northern Iraq. Clear Variation is noticed within the analytical data and reflect differences in location and stratigraphy of the studied springs and wells. It seems that the abundance of highly soluble rocks of Fat’ha Formation (Evaporites and to lesser extent Carbonates) and the formation of Mishraq Sedimentary Sulfur are most effective factors shaping the chemistry of Alradhwania spring water with EC reaches (2.64 µs/cm) at the southern part of the studied area, while the assumed continuous replenishment of aquifer in addition to the fore-mentioned factors, may account for the low EC (around o.4 µs / cm) in wells water drilled in Fat’ha Formation at the southern limb of Bashiqa Anticline .Oxidation of pyrite content of rocks of Shiranish Formation may explain the maximum EC (3.0 µs/cm) of spring water at Germawa Wadi , north west plunge of Bekhair Anticline / Dhuk Area. On the other hand, the low soluble reefal dolomitised limestone of Aqra Formation would accounts for the minimum EC (0.2 µs/cm) of spring water at Abdullazziez Gully / Aqra area. The same remarks may applied to the relatively moderate EC (0.94 µs/cm) of spring water within Pila Spi Formation rocks at the plunge of Bekhaire Anticline / Zawieta / Dhuk Area. Variable effects of rocks of Kolosh And Gercus red bed are noticed in other springs and wells at Bekhaire Anticline / Dhuk Area. Classification of type of spring and well water samples were achieved by plotting the analytical data on Piper trilinear diagram and proper discussion were made backed by the result of calculation of the proposed salt formula phases. Further discussion were extended to cover the environmental significant of analytical data by comparison with world health organization limits. | ||||
