Description:
The long-term performance tests provide information on the first follow-up sampling and analysis on the SITE program demonstration of the International Waste Technologies additive, and the Geo-Con deep soil mixing equipment. he samples containing PCBs, were collected one year after the demonstration, and the chemical and physical test results were compared to those obtained during the demonstration. his was the first part of a 5-year monitoring program on this in-situ stabilization/solidification process. he demonstration was performed in April 1988 at an electric service shop in Hialeah, FL. olume III discusses the results of the long-term monitoring tests and how they compare to the results of the demonstration. he technical criteria used to evaluate the effectiveness of the in-situ process were contaminant mobility--based on leaching and permeability tests--and the potential long-term integrity of the solidified soils--based on physical tests and microstructural studies. his sampling analysis work provides additional evidence on the long-term integrity of the treated soil as well as on contaminant mobility. he overall conclusions obtained, when comparing the long-term and demonstration results, are that the PCB mobility appears to be unchanged and the potential for long-term durability appears to have increased.
