環保署曾於99年委辦「高雄地區大坪頂特定區土壤及地下水品質整體評估及後續管制策略研擬計畫」，初步掌握計畫範圍內270處高污染潛勢區。本計畫係延續前述計畫成果，完成48處場址現勘、13處第一階段淺層調查及7處第二階段深層調查，並完成區域監測井規劃並設置5口區域監測井、執行兩次地下水監測作業，另辦理資訊管理系統初步架構。 兩階段調查結果顯示，計有5處場址發現有害事業廢棄物，超過有害事業廢棄物認定項目為重金屬類之鉛、鎘、鉻與六價鉻，以及戴奧辛，另有部分樣品pH值略高於12.5，顯示為腐蝕性廢棄物，廢棄物種類包含爐碴、集塵灰、廢電石渣等一般事業廢棄物及營建事業廢棄物等。兩次地下水監測並未超過管制標準。另有2處備選場址未辦理第二階段調查，1處場址未發現廢棄物掩埋。 11處完成調查之廢棄物數量估算（1處場址未發現廢棄物掩埋），有害、一般及營建事業廢棄物分別為62,800立方公尺、238,700立方公尺、489,100立方公尺，廢棄物總量為790,600立方公尺。考量離場處理、土木工程及成效評估費用，若符合現行法令規定，有害及一般事業廢棄物一併清理（方案一），清理費用為26億元；若僅清理有害事業廢棄物，一般事業廢棄物轉為資源再利用或原地留置（方案二），清理費用約14.4億元。

The project objectives are to investigate and assess the illegal dumping waste of high pollution contamination potential areas which were marked in “The development plan of soil and groundwater quality overall assessment and the follow-up control strategy in the Depending specific areas of Kaohsiung City” project. Environmental site assessment phase I and preliminary assessments of 48 sites, first phase investigations of 13 sites and second phase investigations of 7 sites have been accomplished. Besides, regional groundwater monitoring plan has been executed and 10 groundwater samplings were implemented to monitor the water quality around the areas. The model of information management system around the areas was also set up. Based on the results of the investigations, 5 sites have identified with burial hazardous industrial waste, 2 sites haven’t been conducted second phase investigations and 1 site hasn’t been found potential of burial illegal dumping waste. The hazardous compounds which were identified include lead, cadmium, chromium, hexavalent chromium, and dioxin. Types of burial illegal waste include slag, (electric arc furnace) dust, carbide slag waste and construction waste. Some of the hazardous waste also was found pH value which is over the standard for defining hazardous waste. Water quality of 10 groundwater samples was qualified with groundwater pollution control standards. 11 sites which have been accomplished investigations also conducted evaluation of burial waste quality and quantity, and cleaning cost estimation (one of 11 sites hasn’t been found potential of burial illegal dumping waste). Sum up the 10 sites evaluations, there are 790,600 m3 of burial waste which contained 62,800 m3 of hazardous industrial waste, 238,700 m3 of general industrial waste, and 489,100 m3 of construction waste. Waste cleaning cost estimation which is included clearance cost, civil engineering cost, and performance evaluation cost. If abiding by laws and regulations is essential, off-site waste included hazardous and general industrial waste, estimated waste cleaning cost is about 2.6 billion (case 1). Or, considering balance of health risk and economic benefits, off-site waste included hazardous industrial waste only, estimated waste cleaning cost is about 1.44 billion (case 2).
