  1. Water Quality Image Analysis

  2. Leaching Images: Use rectangle tool: RGB values => excel => graph

  3. Treatment Images: Use rectangle tool: RGB values => excel => graph OR: Calculate % removal: for a specific rgb value % Removal = 100 * Concbefore - Concafter Concbefore Where… Concbefore = log _(Intensitycontrol)_ (Intensityleachate before) Concafter = log _(Intensitycontrol)_ (Intensityleachate after)

  4. Red: 45 Green: 38 Blue: 11 Red: 53 Green: 54 Blue: 55 Alum Treatment Red: 53 Green: 52 Blue: 49

  5. Treatment Images: Use rectangle tool: RGB values => excel => graph OR: Calculate % removal: for a specific rgb value % Removal = 100 * Concbefore - Concafter Concbefore Where… Concbefore = log _(55)_ = .699 (11) Concafter = log _(55)_ = .050 (49)

  6. Treatment Images: Use rectangle tool: RGB values => excel => graph OR: Calculate % removal: for a specific rgb value % Removal = 100 * .699- .050 = 93% .699 Where… Concbefore = log _(55)_ = .699 (11) Concafter = log _(55)_ = .050 (49)
