The major goal of this project was to check the whole processes that influenced the monitoring data quality obtained from the “The Environment Monitoring of the Water Quality in the Northern, Middle, and Southern Area of Taiwan” program. This year, the monitoring data quality had already been reviewed and the related reports were submitted to Environmental Protection Administration (EPA) each month. The implementations of management, evaluating and analysis of data quality of environmental water were also finished, including stipulating the quality goals of monitoring data, reviewing and audition of the Quality Assurance Project Plans (QAPPs) and Standard Operation Procedures (SOPs) for the proposal “The Environment Monitoring of the Water Quality in the Northern, Middle, and Southern Area of Taiwan”. Also attending the working conferences of the plan, execution of monitoring on site sample collection works 168 times / 415 stations of monitoring on site sample collection works, 156 times / 171 personal-count in 2018, 200 times / 497 stations of monitoring on site sample collection works, 172 times / 176 personal-count in 2019, 184 times / 469 stations of monitoring on site sample collection works, 171 times / 177 personal-count in 2020, 137 times / 363 stations of monitoring on site sample collection works, 107 times / 115 personal-count in 2021, of verifying laboratory works so far this year (2021), standard tests for 14 times, among them standard sample test were 15 sessions items in 2018, 22 sessions items in 2019, 22 sessions items in 2020, 16 sessions items in 2021, assessed the expertise of sample collection staffs and set up the list of qualified personnel, setting up the tabular forms for qualified measuring instruments used in sampling field. For the establishment of environmental water quality monitoring annual report and information-services with updates of the check list operating manual, we have already submitted our 2018, 2019 and 2020, environmental water quality monitoring annual reports, as for the check list operating manual ,data are being summarized and compiled, and a water quality conference was held on 2018/9, 2019/11 and 2020/11. During the executive process of this plan, it was requirement that the improvement and the necessarily processing program should be implemented by the contractors while a fault that might influence the quality of monitoring data was made from them. Moreover, from the executive result of this work, it revealed that the quality of data could be held effectively while personnel's technology and instrumental quality had been required rationally in advance. Generally speaking, besides of cooperating with this plan, if the contractors could strengthen self-checking even more, the promotion of the quality of monitoring data would be more efficient.
