This project starts on March 1, 2022. The tasks include the setup of the monitoring system and checking whether the connection conforms to the law, checking the connection figures of the CWMS and onsite inspection, checking and supervising the function of the CWMS, maintaining the operation of the CWMS integration and management platform of the county, maintaining the mobile monitoring of draining ditches, and the setup of the database server, as well as providing proprietary internet for the bureau. The results of the tasks are as the following: (1) Complete checking the conformity of the law for the controlled companies 30 times and giving feedback for the companies to improve. (2) The abnormities in the controlled companies' figures are constant, over-limited, and zero values. And the zero value is often uploaded to the Bureau as normal or over-limited values. This would affect the record of the monitoring and the authenticity of the effectiveness. (3) The abnormities in the figure show the results of 4 companies are abnormal in both the first half and second half of 2022. They are a. Hong Her Leather CO., LTD (P5104671), the second plant: abnormal in SS, Temp; b. Yun Shern Livestock Farm (P6500097): abnormal in pH; c. I Shan Livestock Farm (P5900084): abnormal in pH; d. King Hi Long CO., LTD. (P6001213): abnormal in the pH of D03. (4) Complete 9 reviews of CWMS-controlled companies’ measures description and 21 reviews of RATA test reports. (5) Complete 5 regular inspections for RATA. They are Union Paper Corporation Lin Nei Plant (P5500191), sewage system of Yun Lin Industrial Park Service Centre (Chu Wei Zi District) (P46A1631), Douliu Industrial Park Service Center.Dedicated sewer system (P4601715), Formosa Chemicals And Fibre Corporation. Mai Liao Factory (P5801773), Chang Chun Plastic CO., LTD. Mai Liao Factory (P5805271). The results show they all conform to Annex 3 of Water Pollution Control Measures and Test Reporting Management Regulations regarding the relative error test except Union Paper Corporation Lin Nei Plant which requires a resample of COD. (6) Complete CWMS data parallel comparison of five factories. They are Formosa Sumco Technology Corporation Mai Liao Silicon Wafer Factory (P5801871), Chang Chun Plastic CO., LTD. Mai Liao Factory (P5805271), NAN YA PLASTICS CORPORATION Mai Liao Factory (P5801513),Formosa Chemicals And Fibre Corporation. Mai Liao Factory (P5801773), FORMOSA ADVANCED TECHNOLOGIES CO., LTD. (P4602196). The comparison results show the overall signal analysis conforms to the one of the Bureau without much difference. That means the figures from the monitoring system to the central control are the same. The transmissions to the Bureau are normal. (7) Maintain the CWMS management and integration platform to ensure the information connection is normal and safe. (8) Complete six maintenances of the mobile monitoring station of water resources and monitor them 7/24 hours. And completed the expansion of the monitoring data of the Action Monitoring Water Resources Monitoring Station to the Yunlin County Environmental Information Integration APP. (9) Hotspots for complaints (Dou Liu Industrial Park): the abnormally high value often reflects on pH and electrical conductivity. The dissolved oxygen is affected by the water fluidity difference in the monitored location. Besides, precipitation also affects water quality. pH and electrical conductivity are diluted and decline when it rains while the dissolved oxygen grows. (10) Hotspots for complaints (Mai Liao Township): the results of monitoring show all tests during the monitoring are normal without particularly high values. Besides, due to the monitoring locates in the estuary, the dissolved oxygen and electrical conductivity are affected by the water temperature, salt concentration in the water and the microbial decomposition of the livestock wastewater. The figures are relatively higher or with no dissolved oxygen. In addition, there are odours of pigs and unidentified floating objects in patrols. (11) Hotspots for complaints (Ko Hu Township): the monitoring results show there are no particularly high values for all items during the monitoring. Besides, due to the monitoring locates in the estuary, the electrical conductivity is affected by ebbs and tides and the salt concentration of the water. The figures are relatively higher. (12) Hotspots for complaints (Hu Wei Township): the monitoring results show that the electrical conductivity and dissolved oxygen of the monitoring spot are affected by the upstream plant, water temperature and microbial decomposition in the water. There is a high pH value occasionally after rain.
