Interrelationship between major, minor and trace elements in Kalabsha wells and in high dam lake waters

Abstract

Major, minor, physical (electrical conductivity) & chemical components (HCO^‐ ₃ ,SO^2‐ ₄,Cl^‐ ,Ca, Mg, Na, K, pH, TDS) and trace elements (Ag, Cd, Co, Cu, Cr, Fe, Mn, Ni, Pb, Sr, and Zn) were determined in Kalabsha wells and in the High Dam Lake water. The water characteristics were followed up in the years 1991, 1992, 1993 and 1994. The results showed higher values for Cond. HCO^‐ ₃ , Cl^‐ , SO^2‐ ₄, Ca, Mg, Na, K, TDS, Ag, Cd, Co, Cu, Cr, Fe, Mn, Ni, Pb, Sr and Zn in the water wells of Kalabsha area than in the Lake water. The pH values of the Lake water were higher than those of the wells water. There is no irregular interrelationship of major, minor and trace elements between the water of Kalabsha wells and the water of the High Dam Lake. However, Lake water is suitable for human consumption. The statistical analysis of the database of wells and Lake water shows positive and significant correlation coefficient values (r=0.665–0.986) between pairs: N: & Co, N. &Zn, Ni&Fe, Mn&Sr,etc.) standard deviation (SD) and coefficient of variance (C.V.%) of the wells and Lake water are in the range 0.19–75 and 0.7–53, respectively.
