Piper diagrams are trilinear representations of the ions found in the water (cations, anions & combined properties) and are used in order to classify water types or chemical facies.

The central field represents the anions and cations in a water sample, and where they lie in terms of mixed-cation-mixed-anion facies and can potentially reveal information about the factors that are controlling the water chemistry plotted.

So you plot your anion and cation TDS on their individual triangles and then extend their lines up onto the diamond diagram, where the two lines intersect is where you would plot that water samples data point. This point tells you about the water sample in terms of its chemistry and the controlling factors.

If multiple data points from different sites are plotted and they form a line, it can be concluded that all the water samples are derived from the same source.
