INTEGRATED REAL-TIME GROUND-WATER/SOIL-GAS MONITORING SYSTEM FOR ANALYSIS OF VOLATILE ORGANIC CHEMICALS

AN INTEGRATED GROUND-WATER/SOIL-GAS MONITORING SYSTEM WILL BE DESIGNED, CONSTRUCTED AND TESTED. THE BASIS OF THE INTEGRATED SYSTEM WILL BE TO PLACE THE VOLATILE ORGANIC CHEMICALS (VOCS) INTO THE SAME SAMPLE FORM, I.E. VOCS IN AN INERT GAS SUCH AS NITROGEN, FOR ANALYSIS. TO ACCOMPLISH THIS A GROUND-WATER SAMPLER WILL BE DESIGNED WHICH WILL COLLECT A GROUND-WATER SAMPLE WITHOUT PURGING THE WELLS. THE WATER SAMPLE WILL BE STRIPPED OF VOCS USING A STREAM OF NITROGEN GAS WITHIN THE BODY OF THE SAMPLER. THE VOCS IN A STREAM OF NITROGEN WILL BE CONDUCTED BY PIPING TO THE SURFACE FOR REAL-TIME ANALYSIS BY A GAS CHROMATOGRAPH. THE SAME GAS CHROMATOGRAPH WILL BE USED TO ANALYSIS SOIL-GAS. THE FIRST PART OF THE WORK PLAN WILL INCLUDE DESIGNING, CONSTRUCTING AND TESTING THE GROUNDWATER SAMPLER. THE SECOND PART OF THE WORK PLAN WILL INTEGRATE THE GROUND-WATER SAMPLER WITH SOIL-GAS MONITORING WELLS TO CREATE A REAL-TIME MONITORING SYSTEM IN WHICH SOIL-GAS DATA MAY BE DIRECTLY CORRELATED WITH GROUND-WATER DATA.
