ABSTRACT
Taipei ShanChu Keng Landfill Place，cost up to 7.4 billions NTD, capacity 6.17 millions m3，was constructed to treat the wastes from Taipei City. The treatment object was major in raw wastes until Neihu、Mucha、Petiou refuse incineration plant completed. The treatment quantity reached 522,410 meter ton by end of 2000.
The defected construction has been denoted by audit system. However, it has caused leachate leached out water collection system、landfill section seal failed、 paved-clothes breached
etc. for these years. Hazardous、 dissolved、 heavy metal wastes、ash dumped up on the site and without treatment. The leachate from the waste contained lead、cadmium、arsenic, which contaminated the underground water when leached out water collection system.
Sewage flooded into ShanChu Keng and Da-An river, it caused downstream serious pollution. For these years, the suspending solid and heavy metal content were over the control index. The index from monitor well also proved the fact. The real pollution situation may be even more serious than the figures from the reports because the monitor system is not completed.
To prohibit the contamination continuously, plant should revise the performed procedure and restrain hazardous wastes buried on site. The ash should be solidified and stored in closed buried section. The organic compounds could be treated by biological methods. After plant site take such captioned operations that the pollution can be controlled.
