本計畫乃屏東縣環境保護局(以下簡稱環保局)依據「土壤及地下水污染整治法」第六條之規定，針對轄區內土壤及地下水品質狀況進行定期檢測，檢測結果若有污染物濃度達土壤或地下水污染監測標準或管制標準者，均應採取適當之措施。工作項目包括地下民井水質採樣分析、簡易自來水採樣分析、監測井外部維護修繕及洗井作業、以及農地土壤採樣分析作業。本計畫執行之效益乃掌握屏東縣土壤及地下水之環境現況，以確保本地土水品質及人民健康。 地下水檢測方面於林邊鄉鎮林段附近擇5口地下水民井，分析地下水中8項重金屬（銅、汞、鋅、鉛、鉻、鎘、砷、鎳）之含量。檢測結果顯示5口地下水民井銅、汞、鋅、鉛、鉻、鎘、鎳均為ND(未檢出)，僅砷測得濃度於0.008~0.107 mg/L之間，因為此區域並非第一類飲用水水源水質保護區內之地下水，乃為第二類為第一類以外之地下水，砷之法規管制標準為0.500 mg/L，因此均符合法規標準。 簡易自來水檢測乃於鹽埔鄉久愛村、振興村、高朗村進行採樣，水質檢測項目為：二氯甲烷、1,1-二氯乙烷、1,2-二氯乙烷、1,1-二氯乙烯、三氯乙烯等，共6口次。分析結果顯示，水中二氯甲烷、1,1-二氯甲烷、1,2--二氯甲烷、1,1-二氯乙烯、三氯乙烯濃度均為ND (未檢出)。 屏東縣內75口監測井維護及洗井作業方面，監測井外部維護，監測井共統計以下之設備缺失：警示柱斷裂共5根 (新圍國小、橋德國小、海鷗公園)、警示柱遺失1根 (以栗國小)、保護套管帽及井鎖遺失2處 (麟洛國小、河濱公園)、標示牌井號錯誤2處 (潮州國中、玉光國小)、現場施工中 (高樹國小)，有關監測井外部設備缺失部分已全部修繕完成。監測井洗井作業之執行，共發現6口無法洗井之監測井，分別為加祿國小、後庄國小、土庫國小、四林國小、崁頂國小、及高樹國小，異物種類以樹根居多，其次為手套、塑膠管等異物，上述6口監測井均已完成異物排除，並均已完成洗井作業。 本計畫進行潮州鎮農地土壤60區塊採樣分析作業，土壤8項重金屬分析結果顯示，S40區塊汞測得6.64 mg/Kg超過農地土壤管制標準5 mg/Kg，其餘區塊之重金屬濃度均符合農地土壤監測標準。 崁頂鄉農地8點位進行土壤採樣，分析結果顯示砷測得最小值 11.8 mg/Kg，最大值100 mg/Kg，平均值33.6 mg/Kg。土壤監測標準(農地)為30 mg/Kg，土壤管制標準(農地)為60 mg/Kg，檢測結果S4區塊表土測得48.8 mg/Kg、S6區塊表土測得54.2 mg/Kg，超過土壤監測標準(農地) 30 mg/Kg，而S8區塊表土測得87.1 mg/Kg，裏土測得100 mg/Kg，超過土壤管制標準(農地) 60 mg/Kg。 本計畫為持續性之計畫，由本年度執行成果針對後續年度之工作進行建議，有關執行地下民井及簡易自來水採樣分析作業，後續計畫可依法規之管制項目增加檢測項目。監測井內部發現有若干破壞現象或是樹根穿過，由於樹根將對井篩造成破壞，後續應進行微水試驗並評估其監測井之功能適用性。農地土壤檢測結果顯示有多處土壤中汞或砷濃度超過法規標準之場址，均為在地農民之損失，建議參考學術單位研究，提出適宜種植之農作物建議以提供農民參考，並訂定類同案件行政程序應變作業程序。

The plan is that the Pingtung County Environmental Protection Bureau (hereinafter referred to as the Environmental Protection Agency) conducts regular inspections on the soil and groundwater quality in the area under the provisions of Article 6 of the Soil and Groundwater Pollution Remediation Law. Those who have reached monitoring standards or regulatory standards for soil or groundwater pollution should take appropriate measures. Work items include underground water quality sampling analysis, simple tap water sampling analysis, monitoring wells external maintenance repair and well cleaning operations, and agricultural soil sampling and analysis operations. The benefits of the implementation of this project are to grasp the current conditions of soil and groundwater in Pingtung County to ensure the quality of local soil water and people's health. For groundwater detection, five groundwater wells were selected near the township of Linbian, and 8 heavy metals in groundwater were analyzed ( Content of copper, mercury, zinc, lead, chromium, cadmium, arsenic, and nickel. The test results showed that the five groundwater miners copper, mercury, zinc, lead, chromium, cadmium, and nickel were all NDs (not detected). The arsenic concentration was only measured between 0.008 and 0.107 mg/L, because this area is not the first The groundwater in the Class I drinking water source water quality protection zone is the groundwater of the second type except the first type. The regulation standard for arsenic is 0.500 mg/L, and therefore all meet the regulatory standards. Simple tap water testing was conducted at the Jiuai Village, Zhenxing Village and Gaolang Village in Yanpu Township. Water quality testing items were: dichloromethane, 1,1-dichloroethane, 1,2-dichloroethane, 1, 1-dichloroethylene, trichloroethylene, etc., 6 times in total. The analysis results showed that the concentrations of dichloromethane, 1,1-dichloromethane, 1,2-dichloromethane, vinylidene chloride, and trichloroethylene in water were all ND (not detected). In the maintenance and well-washing operations of 75 monitoring wells in Pingdong County, the external maintenance of the monitoring wells, the monitoring wells counted the following equipment missing: a total of five warning column breaks (Shin Wai Junior College, Bridge German Small, Seagull Park), warning One column was lost (by Li Guoguo), the protective casing cap and the well lock were lost (Langluo Elementary School and Hebin Park), and the signboards were wrong in two places (Chaozhou National High School, Yuguang Elementary School), on-site During the construction (Gaoshu Elementary School), the missing parts of the related monitoring well external equipment have all been repaired and completed. A total of six monitoring wells that could not be well-washed were found in the monitoring wells' well-washing operations. They were Jialu Elementary School, Houzhuang Elementary School, Tujia Elementary School, Silin Elementary, Xiaoding Elementary, and Gaoshu Elementary School. The most common types of foreign bodies are roots, followed by gloves, plastic tubes, and other foreign materials. The above six monitoring wells have been cleared of foreign bodies and all have been well-washed. The project carried out sampling and analysis operations in Block 60 of Chaozhou Township's agricultural soil. Eight soil heavy metals analysis results showed that the mercury in S40 block measured 6.64 mg/Kg exceeded the soil control standard of farmland 5 mg/Kg, and the concentrations of heavy metals in the remaining blocks were Meet the soil monitoring standards for agricultural land. Soil sampling was carried out at 8 o'clock on the agricultural land in the Panding Township. The analysis showed that the arsenic measured a minimum of 11.8 mg/Kg and a maximum of 100 mg/Kg with an average of 33.6 mg/Kg. The soil monitoring standard (farming land) was 30 mg/Kg, and the soil control standard (farming land) was 60 mg/Kg. The results of the test were 48.8 mg/Kg for the top soil in the S4 block and 54.2 mg/Kg for the top soil in the S6 block, exceeding the soil. The monitoring standard (farmland) was 30 mg/Kg, while the top soil in the S8 block measured 87.1 mg/Kg, and the soil measured 100 mg/Kg, exceeding the soil control standard (farmland) 60 mg/Kg. The plan is a continuous plan. The implementation results for the current year will be used for the recommendations for the follow-up work. The implementation of submerged manholes and simple tap water sampling and analysis operations will enable the follow-up projects to increase inspection items according to regulations and regulations. A number of damages are found inside the monitoring well or the roots pass through. Because the roots of the monitoring wells will damage the well screens, follow-up tests should be conducted to evaluate the functional applicability of the monitoring wells. Agricultural soil test results show that there are many sites where the concentration of mercury or arsenic in the soil exceeds the regulatory standards. All of them are losses of land-based farmers. It is recommended to refer to academic units for research and propose crops suitable for planting in order to provide farmers with reference and set the class. With the case of administrative procedures for operational procedures.
