When blue and red point phlot point On the diagram to have the piper hydrochemical evolution (red line) to point out the change of chemistry of water by Cation exchange reaction (Appelo and Postma, 2005).
When the plot blue point and red point on the piper diagram are lines that show hydrochemical evolution (red line) which indicates the changes in the chemical composition of water by Cation exchange reaction (Appelo and Postma, 2005).
When the physical slot blue and point red point on Piper diagram to the line that shows hydrochemical evolution (red line) indicate the change of the chemical components of water. By Cation exchange reaction (Appelo, and Postma 2005).
