  29. Asg. 1.1 Subsurface migration of DNAPL Attached is a contour map of the aquitard (confining formation at the base of an aquifer at Operable Unit No. 2 in Hill Air Force Base in Utah. The ground level is approximately 4694 ft. The water table is seasonal and can vary from 20 to 30 ft below the ground surface. Disposal trenches in the vicinity of U2-33 was used to dispose unknown quantities of trichloroethylene (TCE) bottoms from the solvent recovery unit and sludge from the vapor degreasers from 1967 to 1975. Dense nonaqueous phase liquid (DNAPL) has been found in a number of wells and borings. Suppose 6 ft of DNAPL was discovered in U2-635. Shade in the areas of the contour map where pools of DNAPL can be expected to be pooled. Also using the attached graph, prepare a plot of a cross-section along the deepest part of the channel. Plot the following: (1) elevation of the aquitard, (2) elevation of the expected DNAPL pools, and (3) location of wells along the deepest part of the channel where DNAPL is expected. Shade the intervals expected to be saturated by DNAPL in these wells.
