Trace elements are rarely distributed in earth's crust and they are invariably in low concentrations. Due to this low concentration they are not analyzed by conventional hydrochemical methods but by rather special techniques with great care. The trace elements are especially useful in detecting the origin of the groundwater in an area. Their regional distribution helps to obtain significant clues on the groundwater movement and mixture processes. It is proposed, herein to assess the trace element concentration available at far distant points by employing the cumulative semivariogram models. These models furnish further systematic interpretations about trace element areal extends, concentration directions, groundwater movement and its continuity.
