FIELD-SCALE TRACER TESTS FOR EVALUATING AIR SPARGING AND IN-WELL AERATION SYSTEM PILOT STUDY

 
G.P. Cobb, T.W. LaPoint, S.T. McMurry, and M.J. Hooper, Department of Environmental Toxicology and The Institute of Wildlife and Environmental Toxicology, Clemson University, Pendleton, SC 29670 Tracer tests were conducted in support of a field-scale pilot study to evaluate the effectiveness of air sparging and in-well aeration for bioremediation of a gasoline contaminated site. Multiple tracers, including sulfur hexafluoride, helium, bromide, and fluorescein, were used to allow for multiple testing without background interference.

Bromide and fluorescein were monitored in the saturated zone; sulfur hexafluoride was monitored in both the saturated and unsaturated zones; and helium was monitored in the unsaturated zone. Tracer data from the field study were used to determine flow patterns, flow rates, and volumes of influence for the treatments.

Key words: tracers, ground water remediation, air injection, in-well aeration, air sparging
