本計畫的主要工作目標有六項：(1) 針對高雄市(原高雄縣)境內具高污染潛勢加油站進行初步污染調查工作，並辦理土壤及地下水污染整治法相關法規說明會，以宣導土壤及地下水相關法令規定；(2) 監督及查核各列管土壤及地下水污染場址之相關工作計畫書，並執行定期監測及後續相關檢驗複驗事宜，以評估污染改善成效；(3) 辦理土壤及地下水污染事件之緊急應變工作，以有效控制污染影響，並減輕或避免場址對環境的可能危害；(4) 針對二仁溪流域地下水質監測井之設置暨監測；(5) 針對具高污染潛勢農地進行污染調查，以掌握農地土壤之現況；(6) 針對鳳山圳流域鄰近農地土壤及底泥進行污染調查及追蹤工作，以掌握農地遭收污染灌溉水影響程度。各項工作的執行成果，分別簡述如下: 加油站污染潛勢調查工作共分為三階段執行，第一階段調查係針對土壤氣體濃度進行普查工作(包括測漏管及貫入式土壤間隙氣體調查)，共完成25站次加油站之459支測漏管基本功能測試及油氣之LEL、PID及FID檢測，20點土壤間隙氣體之PID及FID檢測。測漏管油氣濃度測值的評估結果，具高污染潛勢(B級)僅有1站。第二階段調查對象係根據第一階段調查結果進行篩選，並配合環保局指示，共計有7站加油站。 第二階段調查共完成7站加油站之20點土壤採樣及檢測分析、12口簡易井設置及地下水採樣與檢測分析。檢測分析結果顯示，計有3站加油站之土壤污染物濃度達土壤污染管制標準；有4站加油站之簡易井地下水污染物濃度達地下水污染管制標準。於第三階段調查之4站加油站中，計有4站加油站之地下水污染物濃度達地下水污染管制標準。 總結本計畫加油站調查結果，共計有4站加油站之土壤污染物濃度或地下水污染物濃度超過管制標準，後續均應依土壤及地下水污染整治法相關規定進行管制。本計畫於執行期間亦已於本洲工業區垃圾資源回收廠及高雄市環保局各舉辦1場次之「高雄縣環保局土壤及地下水污染防治工作」法規說明會，共計2場次。 針對已公告控制或整治場址之監督查核工作，本計畫於8處地下水污染控制或整治場址，完成豐、枯水期共計54口次的監測井採樣與地下水分析工作。地下水調查結果顯示，除了3處場址並未檢測出高於污染管制標準之污染外，其餘5處場址仍含有高於污染管制標準之污染物，其中，統一精工(鳳山二站)含有高於管制標準值20倍之苯(GW1)，最高污染物濃度為4.45 mg/L。於10處土壤污染控制或整治場址，總計完成51組土壤樣品之調查作業，結果顯示，共有6處場址測出含有高於土壤污染管制標準之污染物，其中，以統一精工加油站(鳳山二站)的污染濃度最高，其總石油碳氫化合物濃度為20,000 mg/kg(超標20倍)。此外，本計劃按月進場執行現場巡察工作，共已完成190場次。 緊急應變工作係協助辦理台塑仁武廠廠址內及廠址外共20口監測井之地下水檢測工作，於99年8~9月間完成4次地下水採樣作業，共計61口次地下水樣品。地下水水質分析結果顯示，台塑仁武廠廠址內的地下水污染物濃度較廠址外高，其中，廠外MW-07及MW-12含有超標之污染物，分別是1,2-二氯乙烷及氯乙烯。 二仁溪流域地下水質監測工作共完成2口監測井之設置及調查，由豐、枯水期的地下水檢測結果，顯示2口監測井均含有高於地下水污染監測標準之項目及污染物，包括總溶解固體物、氨氮及重金屬錳，其中，氨氮及重金屬錳高於第二類地下水監測標準值，研判可能是上游河川氨氮污染導致地下水中氨氮濃度偏高，或因周遭的生活污水、農作肥料入滲至地下水，造成地下水中氨氮濃度偏高。 本年度計畫調查結果顯示，10筆地號中除大寮區磚子嗂段3998地號無調查出高於監測標準之重金屬濃度外，其餘9筆農地皆調查出高於監測標準之污染濃度，主要污染物為重金屬鋅。此外，大寮區磚仔嗂段3997地號重金屬鉻濃度(311 mg/kg)超過土壤污染管制標準值(250 mg/kg)。 鳳山圳農地污染調查於美山路30巷測站流域上下游鄰近6公頃農地進行調查(A~F區)，共完成農地土壤60組樣品XRF篩測及25組重金屬樣品細密分析，結果顯示，下游F調查區域的6組土壤樣品重金屬鉻皆高於土壤污染管制標準，相關超標農地地號，環保局後續已進行相關列管工作。為追蹤F區農地污染的可能來源，本計畫依鳳山圳農地土壤調查結果，進行鄰近農地灌溉渠道之底泥重金屬含量調查，結果顯示，除了重金屬砷，其餘重金屬濃度均達底泥品質指標下限值，其中部分採樣點位的重金屬鉻、鎳、銅及鋅濃度高於底泥品質指標上限值，又以重金屬鉻為主要污染物質。綜合上述，鳳山圳鄰近農地(包括F區農地) 研判已遭受到重金屬鉻之污染。

The project objectives mainly include the following six contents: (1) The investigation of farmlands with high potential concern to obtain the current farmland soil quality. (2) The investigation and tracking the farmland soil and sediments quality near Feng-Shan canal to obtain the contamination extent through irrigation. (3) Preliminary investigation of the gas stations in Kaohsiung City with high potential concern and held public meetings relevant to “Soil and Groundwater Pollution Remediation Act” to advocate the act. (4) Supervision and review on remediation proposals of contaminated sites and execution of periodic monitoring and confirmation to evaluate the effect of remediation. (5) Conduct emergency responses to soil and groundwater contamination to reach effective pollution control and to alleviate the potential harm to the environmental. (6) The installation of monitoring well in Erhjen Basin to monitor the groundwater quality. The results from all gas stations investigated concluded that, 4 stations showed concentrations of soil or groundwater pollutants over standards, being restrained by “Soil and Groundwater Pollution Remediation Act” in the future. A total of two public meetings of “Prevention from Soil and Groundwater Contamination” were held at Resources Recover Factory, Ben-Jhou Industrial District and Kaoshing EPB, respectively. Regarding the supervision of announced control or remediation sites, a total of 54 groundwater samples from monitoring wells at eight groundwater control or remediation sites were collected and analyzed during seasonal groundwater fluctuations. The groundwater investigation showed that three sites were not found concentrations of groundwater pollutants over control standards but the other 5 sites were otherwise. Benzene was detected at a station Fengshan no.2, Mech Smile Inc. with over 20 times of control standards, up to 4.45 mg/L. A total of 51 soil samples from 10 soil control or remediation sites were collected and analyzed. The results showed that 6 sites were found concentrations of soil pollutants over control standards. The highest concentration of TPH was detected at a station Fengshan no.2, Mech Smile Inc. , over 20 times of control standards, up to 20,000mg/L. The work of conducting emergency responses is to assist Kaohsiung EPB by analyzing groundwater from 20 monitoring wells inside or outside the Jenwu plant, Formosa Plastics Corporation, implementing 4 events of groundwater sampling, with 61 samples collected in total during August and September, 2010. The groundwater results showed that the concentrations of pollutants inside the Jenwu plant are higher than the pollutants outside., Execeeding concentrations of 1,2-dichloroethane and Chloroethene were detected in MW-07and MW-12, respectively. A total of two monitoring wells in Erhjen Basin were installed and investigated. The results obtained from seasonal groundwater fluctuations indicated that both 2 wells were found concentrations of groundwater pollutants over monitoring standards, including Total Dissolved Solids, Manganese, and Ammonium Nitrogen. Ammonium Nitrogen, and Manganese exceeded groundwater Type II monitoring standard.
