The average RPI of the Tamsui River system in 2022 was in the category of slight pollution, with no stations showing severe pollution on an annual average basis. In addition, the overall water quality of the Nankan River and Laojie River Basin showed a trend of improvement compared to 2021. This project will focus on the improvement of river sections and the development of water quality improvement strategies and remediation measures for three important rivers in the northern region. The project will also organize three river remediation tracking and review meetings or local research conferences. By conducting meetings, it can gather all units' opinions and achieve a consensus on remediation strategies and improvement actions.
For the revised pollution reduction plan for severely polluted stations, this project aims to meet the goal of leaving the category of severe pollution in 2030 in line with the national environmental protection plan objectives. The project proposes improvement strategies and suggestions, evaluating the results of five stations, including Cinhi Bridge… etc. These stations need to add new reduction facilities or increase the strength of existing reduction strategies to meet the target of leaving the category of severe pollution. Meanwhile, the measures currently in progress (such as sewer users connecting to sewage systems) and various water quality improvement facilities under construction, such as Dakwai River Bridge…etc. are expected to meet the target of leaving the category of severe pollution if completed on schedule.
This project collects and summarizes the international trend of water environmental management development, concluding that sustainable water environmental development in our country can be oriented towards 6 aspects: clean water, water use, water stability, water culture, water recreation, and water ecology. The project focuses on the "clean water" aspect of the Environmental Protection Administration's responsibilities and plan to manage water quality classification based on surface water bodies and water quality standards. BOD is selected as the water quality assessment item, adjusting the classification expression method. Using the Tamsui River and Erren River as examples, the results are more sensitive than the RPI assessment, and the water quality status can be further subdivided. At the same time, it echoes the water quality classification of water bodies, which can be more discriminative in water quality management.
In order to promoting total pollution control in domestic water bodies, the agricultural authorities and environmental agencies closely cooperate to monitor and inspect the quality of irrigation water and investigate pollution sources. This project reviews the monitoring and inspection results regularly through the inter-agency platform meetings of the Ministry of Agriculture, Land and Water Conservation. The 44 canals with high potential for pollution previously managed by the Council of Agriculture have been completely deregulated, and significant improvements in water quality have been achieved. In line with the strategy to reduce ammonia nitrogen pollution from industrial wastewater, a total of 60 stations across the country affected by industrial pollution have been identified. Due to the large amount of wastewater discharged from industrial areas and scientific industrial parks, downstream river monitoring stations are easily affected. Follow-up evaluations are still needed to assess the effectiveness of ammonia nitrogen reduction measures and conduct a complete investigation of all ammonia nitrogen pollution emissions to further evaluate the necessity of strict ammonia nitrogen control.
To promote the next stage of river quality improvement work, this project compiles relevant policy plans of various agencies, inventories the problems of water quality protection work, sets policy goals and implementation strategies, and drafts a plan for sustainable public water environment construction. Multiple expert consultations and discussions were held to complete the plan content. The Environmental Protection Administration submitted it to the Executive Yuan for review and approval in November of 2022.
The Environmental Protection Administration approved funding for 77 capital projects for local governments. As of December of 2022, 60 projects have been completed. The program also provided subsidies for 15 clean river projects in 15 counties/cities, removing 878.28 metric tons of garbage from rivers in 2022. This project has completed three forward-looking meetings, including three on-site engineering inspections and local government discussions to assist the Environmental Protection Administration in tracking the status of local government forward-looking engineering plans and progress. One business review meeting was held, and through business reports, special presentations, and demonstration highlights, participants exchanged ideas and learned from each other, making it easier to promote forward-looking businesses smoothly. To effectively raise public awareness of local water environment improvement and achieve the effect of environmental policy dissemination, aerial and image recordings of 5 completed water purification facilities and 1 video of a forward-looking project have been completed. In addition, 3 promotional materials, including special articles and promotion cards, have been provided for the use of the Environmental Protection Administration. A survey shows that the public has a positive attitude towards the improvement of water environment facilities and the improvement of nearby water bodies.
To assist the Environmental Protection Administration in understanding environmental protection policies and water quality improvement performance, this project produces several reports, including a national report on the performance of the Water Environment Improvement Plan, a report on the results of the national plan for controlling the total amount of waste water discharge, a national report on river water quality analysis, a report on the implementation of the Water Pollution Prevention and Control Plan for the year 2021, and an inventory analysis of drinking water and tap water intake points in all counties and cities nationwide. These reports enable continuous monitoring of water quality improvement progress.
