AbstractA tracer monitoring program was designed and implemented to monitor water movement through experimental trench caps, and to examine fluorinated aliphatic compounds for use as tracers. Trenches were constructed in Tucson, Arizona and on Mt. Lemon 40 miles northeast of Tucson. The tracers used were fluorinated aromatic and aliphatic organic acids, inorganic halide salts and dyes. Soil water samples were collected using porous cup suction lysimeters placed at various levels inside and outside the experimental trenches. Samples were analyzed for tracers using HPLC and GC methods. Soil moisture was generally low at both sites. Tracer data indicated movement in the cap and through the bottom of several trenches. The fluorinated aliphatic tracers proved useful and reliable to monitor water movement in the unsaturated zone in and around the trenches. Trifluoroacetic and chlorodifluoroacetic acids require further quantitative analytical technique development prior to commercial usage.
