EnviroInsite training workshop - geochemistry visualization tools

  1. 1. Geochemistry Tools EnviroInsite Training Workshop March 2013
  2. 2. What do we mean by geochemistry tools? • Specialized graphics for assessment of dominant aquatic ions • Useful in characterizing ground-water source areas • What are the dominant aquatic ions? Anions – HCO3, CO3, SO4, NO3, Cl, Fl Cations – Ca, Mg, Na, K, Fe EnviroInsite Training
  3. 3. What do we mean by geochemistry tools? • Concentrations plotted as milliequivalents per liter • Conc. in meq/L = Conc. in mg/L divided by equivalent weight • Equivalent weight – ion’s atomic weight divided by its valence Carbonate CO3 Molecular Weight 60 amu Valence -2 Equivalent Weight -30 amu Carbonate CO3 Concentration 1200 mg/L Concentration 4 milliequivalents/L EnviroInsite Training
  4. 4. Entering Data for Geochemistry Tools • Equivalent weight entered in the Constituents table • Anion equivalent weight entered as negative values Ion Equivalent Weight Cl -35.45 HCO3 -61.01 SO4 -48 Mg 12.15 Na 22.99 K 39.1 Ca 20 Fl -19 EnviroInsite Training
  5. 5. Conventional Stiff Diagram • Cations on left / Anions on Right • Plotted in concentration units of meq/L EnviroInsite Training
  6. 6. Piper Diagram EnviroInsite Training
  7. 7. Durov Diagram EnviroInsite Training
  8. 8. Schoeller Diagram EnviroInsite Training
  9. 9. Geochemistry Tools Hands-on Exercise
