AqQA - easy-to-use, water analysis consistency checking and plotting (Piper, Stiff, Ternary, Durov and more)

Why use Excel, when you can use AqQA?

  • Create Piper diagram, Stiff diagram, Ternary, and 8 other plot types
  • Instant unit conversion -- shift effortlessly among units
  • Check water analyses for internal consistency
  • Manage water data in a spreadsheet

Still storing your water analyses in Excel? AqQA was created with water engineers and aqueous geochemists in mind - or for that matter, anyone who keeps water chemistry data in a spreadsheet. With the AqQA spreadsheet, you can:

  • Paste data directly from Excel
  • Convert units with a mouse click -- no more keying in mole weights!
Piper Diagram  

  • Use common spreadsheet tools such as copy, paste, transpose, sort, and many others...
  • Compare replicate analyses and check standards
Stiff Diagram  

  • Mix samples
  • Flag exceedances of regulatory limits
Ternary Diagram  

  • Check for internal consistency against AWWA standards
  • Calculate fluid properties such as water type, TDS, hardness, conductivity and carbonate speciation
Durov Diagram  

  • Calculate calcite saturation and CO2 fugacity
  • Quickly create Piper, Stiff, Ternary, Durov, and 7 other plot types
