I know this diagram which is often used and cited but to be honest, as an economic and environmental geologist, I have not yet found any results which would have catered for one of the two geo-disciplines of mine and where an attempt has been made to interlock it with one of its neighboring disciplines geology and mineralogy that should be used prior to it. I can imagine it might be good for a nice paper but what else? Where has it been used with reasonable results obtained for that scope I referred to above. I am open for some hints so as to brush away my skepticism of such narrowminded chemical philosopher´s stones.

Hello Gundala Vijayakumar , Please refer to the following paper for HFE Diagram.

Giménez-Forcada E (2019) Use of the Hydrochemical Facies Diagram (HFE-D) for the evaluation of salinization by seawater intrusion in the coastal Oropesa Plain: Comparative analysis with the coastal Vinaroz Plain, Spain. HydroResearch 2:76-84. https://doi.org/10.1016/j.hydres.2019.11.007.

Hi Gundala Vijayakumar ,

If you need a platform to prepare HFE-D, i think you can use the excel file prepared by Gimenez-Forcada from University of Salamanca at this page:

But again, I think it's better to consider the suggestion from Prof. Harald Dill.

Dear Saefudin Thank you for your suggestion.
