Abstract
TEXAS RESEARCH INSTITUTE, INC., RECENTLY CONCLUDED A SUCCESSFUL EXPERIMENTAL INVESTIGATION OF A MODEL SYSTEM FOR VENTING UNDERGROUND GASOLINE SPILLS. THE RESULTS INDICATE THAT VENTING PROVIDES A VIABLE WAY OF REMOVING THE CONTAMINANT WHILE PREVENTING VAPORS FROM ESCAPING ABOVE GROUND. IT IS PROPOSED THAT THESE RESULTS BE USED AS A BASIS FOR THEDEVELOPMENT OF A MATHEMATICAL MODEL WHICH RELATES THE RELEVANT OUTPUT PARAMETERS OF THE PROBLEM (EG., FLOW RATES, CONCENTRATION PROFILES) TO THE GIVEN VENTING CONDITIONS (EG., SOIL CONDITIONS, DEPTH OF WATER TABLE, BOUNDARY CONDITIONS). THE MODEL WILL BE DEVELOPED FROM THE FUNDAMENTAL LAWS FOR DIFFUSION AND FLOW THROUGH POROUS MEDIA. PROVEN NUMERICAL METHODS WILL BE EMPLOYED TO SOLVE THE EQUATIONS FOR THE VARIETY OF CONDITIONS ENCOUNTERED IN FIELD VENTING APPLICATIONS. REFINEMENTS TO THE MODEL WILL BE MADE ON THE BASIS OF COMPARISONS BETWEEN PREDICTED AND MEASURED CONCENTRATION PROFILES. THE GOAL OF THIS RESEARCH IS TO PRODUCE A TRACTABLE MODEL WHICH CAN PREDICT THE OUTCOME OF A VARIETY OF VENTING DESIGNS FOR CONTROLLING VAPORS EMITTED BY UNDERGROUND SPILLAGE OF TOXIC MATERIALS.
