摘要

The objective of this contract modification is to continue compiling leachate data from an actual field disposal site so that the correlation of field and laboratory data required in the original objective can be completed. Groundwater and interstitial water samples from the Center, North Dakota field disposal site are being obtained and analyzed. As indicated in the statement of work, the analytical data from the wet pit field disposal site is to be collected and correlated with existing data produced during the laboratory leaching and extraction portion of the contract. The water analyses from piezometers and interstitial water analyses from both clay and FGD waste are presented. Chemical analyses for specified leaching column pore volume displacements in the laboratory for both gravity and vacuum flow were performed. It is observed that leaching column studies are not dependent on the type of water used or whether gravity or a vacuum are employed. Results of similar chemical analyses for both the ASTM Method A - Water Shake Extraction Procedure and the EPA - Toxicant Extraction procedure (TEP) are presented. As with the leaching columns, the ASTM Method is not dependent on the type of water. There is relatively good correlation between the ASTM extraction data and the analyses for the 0-2 pore volume displacement from the leaching columns. The determination of the validity of laboratory leaching with respect to field leaching will hopefully be done by a comparison of the cumulative concentrations of the various trace metals and major species, expressed as mg/g or mu g/g, for the same pore volume displacements.
