In order to improve the quality and the safety as well as hygiene of construction sites of the “improvement construction of water quality”, the “Orientation of Inspection for Water Quality Improvement Construction” was held on June 4, 2008, the “Learning of Water Quality Improvement Construction” was held on October 17, 2008, and the “Review of Water Quality Improvement Construction” was held on November 6, 2008. Committee meetings of inspection for construction were held for 19 times and there were 3 inspection reports. The sample (format) of ‘Work Plan”, “Quality Control”, and “Plan of Direct” were also established
Up to November, 2008, Water Quality Improvement and Renovate Project for all of the five metropolitan rivers are undergoing. 21 water quality monitoring stations have moved from moderate polluted to slightly polluted, which surpasses the goal of 15 water quality monitoring station. The river length of slightly polluted has reduced to 74.2%, which is still 0.8% more than the goal. WQI is 71 and CTSI is 43.76, both have achieved the goal of 2008.
The green accounting for 2007 of the point pollution for 30 river basins showed that, BOD is 156,303 ton, COD is 372, 508 ton, SS is 151, 648 ton, and NH4+－N is 30,112 ton. From the estimation, it is shown that 8781.36 kg/day of BOD discharge and 14296.3 kg/day of NH4+－N discharge are required to reduced for Dong-Gang river. The downstream of the A-Gong-Dian River is categories D, therefore, there are no BOD and NH4+－N standard. For the upper stream of the A-Gong-Dian River, the discharge of BOD is under the limit, however, reduction of 273.2kg/day of NH4+－N is required, which is 1bout 75.3% of the total discharge.
The expansion of function of the establishment of data in the “Protection of Water Quality Management System” has been accomplished. New functions required by EPA, such as progress report, project holding, and assessment of project have been included.
