Abstract:	環保署於99年修法公告將河川、灌溉渠道、水庫湖泊底泥納入「土壤及地下水污染防治法」規範，並公告相關子法，於103年起執行第一階段5年全面檢測調查，作為日後水體底泥管制啟動點。惟環保署對於底泥品質逾限問題，國內並無明確整治處理機制及配套規範。本研究以桃園市政府水務局於107年完成老街溪底泥調查結果分析，主要為重金屬銅、鉛、鋅污染，對照流域內工業區相關位置，顯示工業區排放口下游為底泥污染較嚴重。透過文獻回顧及整治工法探討後，污染底泥經評估後，對於環境有危害之虞，建議將底泥疏濬後，作為控制性低強度回填材料之原料，除了解決底泥污染問題，亦提供循環經濟最佳應用管道。 ;In 2010, the Environmental Protection Administration announced that rivers, irrigation channels, reservoirs and lake sediments would be included in the "Soil and Groundwater Pollution Remediation Act" and related sub-laws. The first phase of a 5-year comprehensive inspection and survey was implemented in 2014 as the starting point for monitoring the sediment of the water bodies. However, the Environmental Protection Administration has no clear treatment mechanism or supporting regulations for dealing with poor sediment quality. This study is based on analysis of the results of the Lao-Jie River sediment survey carried out by Taoyuan City Government Department of Water Resources in 2018, which focused on heavy metals, copper, lead, and zinc pollution. It shows that, compared with locations in the industrial zone of the basin, sediment pollution is more serious downstream of the industrial zone discharge outlet. After reviewing the literature and discussing the remediation method, the contaminated sediment is assessed to be harmful to the environment. It is recommended that the sediment be dredged and used as raw material for Controlled Low Strength Material. As well as removing the pollution, recycling in this way also provides a more environmental and economic way to dispose of the sediment.
