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.
