Evaluation of Natural Treatment Sysetems (NTS) executed from July 11, 2009 to March 31, 2010. A summary of working items are as follows: 1. There were total 118 on-site patrols for four sites in this project. Among those patrols, there were 41 defects which reported for further improvement.

The result is shown as follows: Table 2: Patrol Details of Guan-Yin-Ting and Communication Barrack of Army Item Guan-Yin-Ting Communication Barrack of Army Total Patrol 24 21 Reported Defects 12 9 Improved Cases 12 9 Period: July 11, 2009 to March 31, 2010 2. Water samples for Non-Point Sources from the NTSs sites have been analyzed. According to water-quality report, the improving results have been evaluated.

Samples of sediments and Aquatic Plants collected from Hong-Lo and North-Eastern Converging Entrance have been examined twice. Result of the analysis provided better understanding for the surrounding environment. 4. The previous two-year database on ecological investigation from four NTS sites has been arranged: Hong-Lo, The North-Eastern Converging Entrance, Tong -Xin -Hu and Huo-Shaso-Ping. Moreover, the illustrated handbook of variety organisms and Ecological-Magnet-Billboard for educational propose were made during this project. 5. Top-Seed Teacher Training Conference was held twice at demonstration sites. 6. This project also completed the following contain of work: A. Purchased 30 sets of Water Monitoring (WWMD) Test Kit B. Completed Top-Seed Teacher Training Conference C. Proceeded 5 series of Water Monitoring activities D. Assisted EPB in arranging the “World Monitoring Day Carnival, 2009” on Sep. 17, 2009. 7. This project was not only maintained contracted sites but also assisted EPB at Gun-Yi-Ting’s and Communication Barrack of Army’s NTS facilities’ Educational Training in order to cooperate with EPA’s achievement inspection. In Addition, we gave suggestions to correct error and consult on improvement plan. On Aug. 24, 2009, we have completed the self-checked procedure by inviting Prof. Lee and Prof. Huang to give professional comments, and the EPA on-site checked and accepted on Sep. 4, 2009.
