  1. Fate of Arsenic and Trace Elements in Deep Aquifer water of Bangladesh: Experimental Measurement and Chemical Equilibrium Model Mohammad Alauddin Wagner College, NY, USA

  2. WATER QUALITY ANALYSIS

  3. WATER QUALITY ANALYSIS

  4. Deep Tube Well Water Samples

  5. SPECIES DISTRIBUTION WHEN ALL IRON PPT OUT AND ACT AS SURFACE COMPLEXING AGENT

  6. J1 more realistic

  7. Assume oxic condition and all Fe(II) to Fe(III) Without surface complexation or Adsorption

  8. Conclusions *Under anoxic condition Ba helps precipitation of As *Fate and speciation of As and other component are linked to formation of HFO. *Adsorption and surface complexation are responsible for species immobilization *Arsenite,Arsenate,Phosphate are believed to be fully adsorbed on the HFO. *Deep aquifer water seems to be a safe drinking water option at least for a short term
