default units for water type calculations in GSS and piper plots in Gtplot


Recommended Posts

  1. Is the water type calculation based on conventional units of meq/L? What is the classification criteria? I assume the dominant cation and anion even is less than 50% of total positive or negative charge?

The water type calculation shows the single most abundant cation and anion species, based on concentrations in meq/kg fluid. There is no requirement that a cation or anion must contribute 50% of the total positive or negative charge.


Piper diagrams, along with the other specialty plots, are plotted in meq/kg fluid.
