台南市三爺溪、二仁溪段非法棄置不明廢棄物緊急調查及清理規劃計畫（環保局）
| 中文摘要 | 本計畫是配合依二仁溪污染整治及再生願景計畫，完成台南市南區二仁溪北側三爺（宮）溪(與台南縣交接處)至出海口旁之河岸棄置不明廢棄物分布調查工作。已完成調查範圍界定、電磁波探測、採樣計畫規劃、現場開挖30點與鑽探10點工作、以及採集44組樣品、完成其XRF篩選、TCLP重金屬檢測、廢棄物數量估算與清理工作規劃等工作。 調查結果顯示A區TCLP重金屬檢測結果超過溶出標準，超標項目為鉛、銅及鎘，且A區戴奧辛樣品亦超過法規標準，顯示此區掩埋物除重金屬污染外，亦有戴奧辛污染之問題。 B、G、H等三區域，經調查並未發現埋有廢棄物。D、E兩區域則發現有一般（事業）廢棄物而未發現有害事業廢棄物。C區則在河堤道路旁發現大量營建廢棄物棄置之情形，雖多屬回填土，但其中夾雜少量有害事業廢棄物；F區及G區經重金屬溶出檢測發現有害事業廢棄物，另I區除重金屬有害事業廢棄物外，戴奧辛檢測含量在法規值之下，但其數值偏高，顯示此區廢棄物亦有戴奧辛污染之問題。在過去地下熔煉廠分佈之A區有戴奧辛含量超過標準之情形，顯示過去人為的活動確實造成此區域之污染仍存在。 總計8區域調查出約有70,930立方公尺之一般（事業）廢棄物，與20,460立方公尺之有害事業廢棄物，清理期程以16個月規劃，預估清理所需費用約為6億4千多萬元。後續為保障居民生活安全與環境品質，建議主管單位儘速責成相關人員，負責廢棄物清理與後續整治之工作。 | ||

Term Report of the “Emergent Site Investigation and Cleanup Planning of the Illegal Disposal Site along San-Yeh River and Erren River in Tainan City” sponsored by Tainan Environmental Protection Bureau
| 英文摘要 | This project was to conduct with the Er-Jen River Remediation and Reclamation. It finished the investigation work of unidentified disposed wastes between Sanye Gong Xi of the north side of the Er-Jen River to the river mouth to the sea, including investigation perimeter allocation, ground radar detection, sampling plan, 30 locations of on-site excavation and 10 locations of soil profiling, 44 sets of sampling, XRF screening, TCLP heavy metal tests, wastes volume estimation, and clean-up planning. The results showed that the concentration of the TCLP test for Zone A was over the legal limit, and the specific metals were lead, copper, and cadmium. The dioxin concentration in Zone A was also over the limit. This concluded that Zone A contained heavy metal and dioxin contaminations. Among Zones B, G, and H, the investigation results did not show the evidence of wastes. Zones D and E contained general industrial wastes but not hazardous ones. Zone C was found large amount of waste building materials containing majorly backfill soil and small amount of hazardous wastes. The TCLP test results of Zones F and G showed containing hazardous wastes, as well as Zone I. Zone I also showed some concerns regarding dioxins concentrations that were close to the legal limit, although they were not over it. Zone A results showed dioxins concentration over the limit, and it was operated by several unregistered metal extracting plants, indicating the contamination caused by business activities in the past still existed. In conclusion, the 8 investigated zones contained about 70,930 m3 of general industrial wastes and 20,460 m3 of hazardous wastes. If the cleanup work lasts about 16 months, the estimated cost for cleanup is about NT$ 644,000,000. In order to safe guard the residents’ living and surrounding quality, it is suggested to group relative personnel responsible for the later-on waste cleanup and site remediation works. | ||
