This plan is based on the Pingtung County Government Environmental Protection Bureau (EPB) in accordance with the provisions of Article 6 of the "Soil and Groundwater Pollution Remediation Law" to conduct regular inspections on the quality of soil and groundwater in the jurisdiction. The work items include sampling and analysis of water quality in underground civilian wells, sampling and analysis of monitoring wells in the potential area of volatile organic compounds (VOCs) in Yanpu Township, and sampling and analysis of 10 sites for the potential of pollution of agricultural soil and agricultural tools in Jiuru Township. The benefit of the implementation of this project is to monitor the environmental status of soil and groundwater in Pingtung County to ensure the quality of local soil and water and the health of the people. The groundwater sampling was performed at 3 underground water civilian wells near 391, 392, 399, 400, etc. of Xinyang Section of Xinyuan Township, and 2 underground water civilian wells near 984 of Liucuozhuang Section of Chaozhou Town. The analysis items are 8 heavy metals (copper, mercury, zinc, lead, chromium, cadmium, arsenic, nickel), The results of the dry season and the wet season showed that the groundwater heavy metal detection items of the 5 civilian wells were all lower than the second-category groundwater monitoring standards; and additional testing, including 3 underground water civilian wells #1 (Lunzi Dinglunxing Palace, Chaozhou Town), #2 (No. 32, Pengcheng 1st Lane, Chaozhou Town), and #3 (No. 86, Pengcheng Road, Chaozhou Town) of the 984 site in the Liucuozhuang section of Chaozhou town, the groundwater heavy metals (mercury) testing results are all lower than the second type groundwater monitoring standard of 0.01 mg/L. Water quality testing of 8 monitoring wells in the potential area of VOCs in Yanpu Township was performed at groundwater monitoring wells T00256, T00257, T00258, T00414-1, T00414-2, T00415-1, T00415-2 and T00469 in Yanpu Township. The test results in the dry season showed that 1,1-Dichloroethylene (1,1-DCE) was detected in 5 groundwater monitoring wells, which the measured values were T00256 (0.00084 mg/L), T00414-1 (0.00323 mg/L), T00414-2 (0.00330 mg/L), T00415-1 (0.00222 mg/L) and T00415-2 (0.00306 mg/L). In the wet season, the measured values of 1,1-DCE were T00256 (0.00099 mg/L), T00414-1 (0.00361 mg/L), T00414-2 (0.00356 mg/L), T00415-1 (0.00275 mg/L) and T00415-2 (0.00348 mg/L). The values all were lower than the second type of groundwater monitoring standard value (0.035 mg/L) and the recommended value for the verification of VOCs detected in groundwater (0.006 mg/L). The 1,1-dichloroethylene of the remaining 3 groundwater monitoring wells are all ND. Sampling and analysis of 8 heavy metals (copper, mercury, zinc, lead, cadmium, chromium, nickel, arsenic) in 60 blocks of agricultural soil in Jiuru Township, the analysis results showed that the zinc concentrations measured by sampling in blocks S34 and S39 are 311 mg/kg and 358 mg/kg respectively. which exceeded the edible crop soil monitoring standard of 260 mg/kg; blocks S34 and S37 samples measured copper concentrations of 121 mg/kg and 187 mg/kg respectively, which exceeded the edible crop soil monitoring standard of 120 mg/kg. The test results of the remaining blocks were all lower than the edible crop soil monitoring standard. In addition, based on the review opinions of the interim report, the heavy metal copper and zinc content of the biogas slurry was tested for the agricultural land in Jiuru Township (S05) where the biogas slurry was used as fertilizer. The analysis result showed that the copper content was 0.028mg/L; the zinc content is 0.11 mg/L. The project implemented the sampling and analysis of heavy metals (copper, zinc or arsenic, cadmium) in soil of 10 potential pollution areas of agricultural land. The analysis results showed that the zinc concentration at T10298 (No. 565, Guang'an Section, Wandan Township, Pingtung County) was 306 mg/kg; T10300 (No.389, Huarong Section, Changzhi Township, Pingtung County) was 348mg/kg; T10302 (No. 116-2, Yonglong Section, Yanpu Township, Pingtung County) was 385mg/kg, which all exceeded the edible crop soil zinc monitoring standard of 260mg/kg. The copper concentration of T10300 (No.389, Huarong Section, Changzhi Township, Pingtung County) was 170mg/kg, which exceeded the edible crop soil monitoring standard of 120mg/kg. It is recommended that follow-up monitoring should be carried out regularly. The concentration of copper and zinc heavy metals in the remaining farmlands did not exceed the soil monitoring standards for edible crop farmland. The prospect of this project is to maintain the safety of local people's water use by performing soil and groundwater testing in areas with potential for pollution, and to ensure the safety of crops for food consumption. The relevant results implemented by the team have met the requirements of this plan.
