Our probe points consist of a four foot slotted rod driven approximately 5 feet below the water table. This places the top of the screen approximately 1 foot below the water table, and the center of the screen approximately 3 feet below the water table. Our plume diving calculations indicate that the top of the plume is 7.75 to 8.73 feet below the water table; 4.75 to 5.73 feet below the center of our sampling point. Had we used a typical 10 foot screened monitoring well we would not have faired much better since the concentration from the well would be the average of the entire 10 foot vertical section which would include 7.75 to 8.73 feet of relatively clean water.
