The Project analyzes the changes in 54 rivers that have been under EPA’s regular monitoring for the last ten years and investigates the water changes at the monitoring stations based on the improving actions taken. The Project, in consideration of the probable distorted reports on the pollution in certain rivers due to the influence of natural factors, also makes suggestion for applicable indicators for water assessment based on the characteristics of pollution in the rivers. Also, after summarizing and analyzing the background data on 28 designated rivers, and considering the capacity of polluting source control in the counties and cities where these rivers run, this project proposes strategies for pollution control in the river basins covering five aspects. The aspects are how clean the water is, ecological conservation, effectiveness of waterfront environment regeneration/total administration, government administration and private sector involvement. While the agencies are promoting the pollution control plans, this project extends assistance in urging the county/city governments to operate and maintain the in-situ water cleansing facilities properly to fulfill the object of autonomous site management and to be comprehensive of the efforts and effectiveness of the local water improvement in waters. While the effectiveness of control is being seen in the counties and cities, the responsibility for water quality at monitoring stations that straddle multiple counties/cities has yet to be attributed. Hence this project uses the survey on the effluent quality and volume in the branches or the data on controlled businesses that might affect the inter-city monitoring stations to analyze the pollution load in the counties and cities, which results serve as reference in determining the responsibility for the water quality at inter-city monitoring stations. This project also completes the preparation of the 2013 Green GDP to provide EPA as reference in its administration and for the Directorate-General of Budget, Accounting and Statistics, Executive Yuan to do the environmental accounting with. General affairs of environmental water quality improvement carried out in the project also include the formulation of total reduction at polluting sources and control measures for the river sections with non-conforming heavy metals; giving recommendation for actions to prevent suspended solids in river from causing abnormal water quality after summarizing the environmental protection specifications regarding river dredging works in Taiwan; and analysis in the operations of offshore industrial parks.
