The project contains five major subjects. The first subject is to conduct the environmental, soil and groundwater monitoring of public landfills in Yunlin County. The implementation results are as follows: 1. Conduct the soil samples collected from 4 landfill sites which rented land from Taiwan Sugar Corporation for the detection of heavy metals such as arsenic, cadmium, chromium, copper, mercury, nickel, lead and zinc. The test results meet the soil pollution monitoring standards. 2. Monitor groundwater in the landfill sites. The results reveal that all testing results meet the Secondary Groundwater Pollution Control Standard specification; While, most exceed items are as the background and indicator water quality project, in order of ammonia nitrogen > manganese > iron > total hardness > TDS > chlorine Salt > Sulfate and other items. 3. Conduct the environmental monitoring in the Huwei Town Landfill Site. The measured value of ambient hydrogen sulfide in Huwei Town meets the 0.1ppm limit of the perimeter standard; the measured value of ammonia nitrogen, iron, and COD are high in the surface water pollution monitoring; the concentration of the ammonia nitrogen and iron had exceed the groundwater pollution monitoring standards. The second subject is to conduct monthly (quarterly) regular supervision of the operating (closed and rehabilitated) landfills within the jurisdiction. Need to enhance the backfilled in the buried area, the maintenance of the biogas pipe and increase the human resource in the operating landfill sites which in Dongshi Town, Sihu Town, Lunbei Town and Erlun Town, etc. Need to improve the cleanliness in the transfer area and the work of waste water collection in the closed landfill sites which in Huwei Town, Linnei Town, Gukeng Town and Dounan Town.
