本研究場址位於屏東縣九如鄉，主要污染物為總石油碳氫化合物（TPH）。 計畫自101 年起執行迄104 年，主要目的在於以生物復育法(蚯蚓與石化分解菌) 改善污染。在場址內共設置六個試驗區，除對照區外，另設有三個生物復育區與 二個為植生復育區。在三年餘的試驗後發現，各復育區之TPH 濃度多呈現降低 趨勢，三個生物復育區土壤中之TPH 濃度減量百分比介於33％～97％，植生復 育區則為19％～81％；不過，多數土層中之TPH 濃度仍高於土壤污染管制標準。

The contaminated site proposed in this study is located at Jiuru Township, Pingtung County, According to previous investigations, the major contaminants in soils were total petroleum hydrocarbon (TPH). The objective of this research project is to conduct remediation in the contaminated site. Five treatment plots were designated in the highly contaminated area, in which three were designed for bio-phytoremediation (BP1, BP2, and BP3) and two for phytoremediation practice (PR1 and PR2). One control plot was used for comparison purposes. Since the initiation of this study in 2012, earthworm (E. fetida) and petroleum-degrading bacteria (Pseudomonas sp. NKNU01) have been utilized for bioremediation, The results of soil analysis showed a trend of decreasing TPH concentrations in most treatment plots, and the removal rate of TPH within the three bio-phytoremediation plots ranged from 33％～97％ and from 19％～81％ in the two phytoremediation plots. However, TPH concentrations were not significantly reduced and thus most soils were still highly contaminated.
