The purpose of this proposal is to do the research for ‘The Handbook of General Waste Sampling” that sdopted since 1984 in Taiwan and the difference of sampling methods between the handbook and the practical execution. Also, the sampling and analysis methods of the general solid waste announced in USA and Japan will be examined to provide the application reference for revising ‘The Handbook of General Waste Sampling”. There are two parts of general waste sampling methods in this proposal. The first one is about general solid waste. The second one is about the fly-ash, bottom residue and solification substance. In the first part, the deficiency and incompletion of ‘The Handbook of General Waste Sampling” will be added and corrected according to the stastic results of investigation of the practical execution in Taiwan and the criteria announced in USA and Japan such as the sampling method requirement abd the procedure guidance of project execution. In the second part, the general standard of sampling methods in Taiwan are similar to the standards adopted in USA. Therefore, the code 7035.2910 (December, 2001) of Minnesota, USA is the important reference to set the detail specifications of sampling methods in this proposal. The appendix A of this proposal is as the operation menu of sampling that includes the standard sampling methods and the execution specifications. The execution specifications are set after solving the execution problem, revising the data sheet of sampling and selection of alternative based on the execution experience of the sampling units and the results of this project. Therefore, the operation menu presented in this proposal could be used in sampling methods training and practical operation.
