Groundwater Pollution by Trace and Secondary Elements in Alton Kupri Basin. N. Iraq

Abstract

The secondary group (Nitrate NO3, Boron B and Fluoride F) with group of Trace elements (Cadmium Cd, Lead Pb, Manganese Mn, Iron Fe, Cupper Cu, Zinc Zn, Nickel Ni and Chromium Cr) of Inorganic category are tested in water wells of Alton Kubri Basin to get suitability for human and agricultural consumption. Result shows the concentration of No3 is more than recommended limits at Nabi- awa, kuchuk bibani, qalwazi and Buyuk- hisar groundwater wells. The concentration of Boron in water wells of Nabi-awa and Zardic shows enrichment above the recommended limits in some months of year. The concentration of Nickel is also higher than the recommended limit in water wells of Dobozni, Qalwazi and Buyuk-hisar wells. Study is illustrated enrichment in the concentration as above reputation of water wells at local area only. The source of enrichment for Nitrate NO3, Boron B and Nickel Ni is originated from the agricultural activities and the natural occurrence of these elements in the rocks consists aquifer.
