I am working on a hydro-geochemical analysis part of my project. We are working in an area were we have more than 150 boreholes tested for their levels of geochemical parameters (major and minor ions and physico-chemicals). We want to conduct an analysis using PHREEQC to see the possible sources (minerals) of the parameters above the maximum contaminant standard and the extents of ion exchange. So, do I have to analyse each well individually, or there is a way to import the whole data (excel or any format) to PHREEQC for analysis? Can PHREEQC be used for multi-well analysis?

Your contribution is much appreciated.
