This project includes four subprojects. The first subproject is focus in inspecting public landfill sites, groundwater sampling and analysis, and revising the data of public landfill sites. The second subproject is evaluating the benefit of the electrical leaching monitor system for monitoring water proof structures of landfill sites. The third subproject assessed the feasibility and advanced the basic planning of the bottom ash reuse plant. The fourth subproject assessed the practicability of the waste transported by railway in Yunlin County, Hualien County and Taitung County. The first subproject inspected 30 public landfill sites(included the professional engineer guidance, which is 60 professionals were invited to participate in the inspection). And also completed the sampling and analysis of upstream and downstream groundwater wells of 35 landfill sites(total of 70 groundwater wells). More than 500 public landfill sites data were revised and updated in this subproject. The second subproject set up the electrical leaching monitor system in both Homei and Shengang landfill sites, and monitored the leaching water proof structure of both landfill sites. According the result of monitoring, had provided the 2D diagram for leaching water proof structure without any break hole, and the 3D diagram for leaching water proof structure with any break hole. The third subproject experimented with washing the bottom ash. However, according the conclusion of the experiment, there is no economic benefits for washing the bottom ash as the first class reused standard of bottom ash which was notified by EPA. But this subproject still advanced the basic planning of the bottom ash reuse plant. The fourth subproject assessed the practicability of the waste transport by railway by the equipment cost, the environment protection, the administration of government, and the will response of the people. By explored 8 railway stations and 1 refuse incineration plant, canvassed with local environmental bureaus and Taiwan railway administration, waste transported by road is better than transported by railway in present Taiwan.
