The execution period of the 2013 Taipei City Soil and Groundwater Pollution Investigation and Verification Work Plan is from January 1, 2020 to December 20, 2020. A summary of the completed work of the plan is as follows.
1. Monitoring well maintenance management and monitoring
Completed annual monitoring well inspection, 5 secondary well condition assessments, 3 secondary monitoring well appearance maintenance, 2 secondary monitoring wells abandoned wells, 1 secondary well body facility repair and 6 secondary monitoring wells groundwater monitoring operations, including A00046 monitoring well The arsenic measurement value exceeds the groundwater pollution monitoring standard; the arsenic measurement value in the A00047, A00048 and A00049 monitoring wells exceeds the groundwater pollution control standard.
2. Storage system review and management
Completed the inspection of underground storage tank systems at 15 stations, among which the P04 FID detection value of leak detection pipes at civil rights gas stations nationwide was 5,230 ppmV; another 8 stations had failed cathodic anti-corrosion functions, and 5 stations were not equipped with cathodic anti-corrosion systems; completed inspections of 20 storage systems During the inspection, a total of 13 locations were found to be non-compliant with laws and regulations; 29 storage system improvement review operations were completed, and the review results showed that 6 locations still did not comply with laws and regulations.
3. Investigation and verification of announced enterprises, other enterprises with pollution potential, or land with suspected pollution
Completed 2 on-site inspections of notified enterprises and conducted soil surveys for Xieji Gas Station. The survey results showed that they all met soil pollution control standards.
4. Agricultural land and business pollution prevention operations
Completed farmland sampling and XRF screening operations for 26 irrigation groups in pollution early warning areas, completed 6 sets of preliminary irrigation water quality inspections and 1 set of water quality re-inspections, completed 44 sets of resin package survey operations; completed 2 group A preventive management operations pre-departure instructions meetings and on-site inspection operations, completed 1 group B independent prevention management publicity briefing and 8 on-site inspection operations, and completed on-site inspection operations for 11 group C businesses.
5. Site management and inspection operations
There are 3 control sites and 4 necessary response measures sites in this city every year, among which the Songshan Airport gas station has been delisted.
6. Sediment survey operations
Three water body sediment investigation operations have been completed that are higher than the upper limit of the sediment quality index. Among them, the heavy metal zinc in the Yide Pumping Machine Zhen sediment exceeded the upper limit of the sediment quality index, and the heavy metal copper in the Dashijiao Zhen sediment exceeded the sediment quality index. The upper limit value is that although the heavy metals in the sediment of Shuiqianzhen do not exceed the upper limit value of sediment quality, the heavy metals chromium, nickel and zinc exceed the lower limit value of sediment quality; the bottom processing of water bodies that does not exceed the upper limit value of sediment quality has been completed. During the mud survey operation, the heavy metal zinc at point M01 (near Wanban Bridge in Shuangyuan Riverside Park) exceeded the upper limit of sediment quality.
7. Simultaneous sampling survey of soil in edible crop farmland and sampling survey of specific edible crop planting bases
14 simultaneous sampling surveys of soil in edible crop farmland have been completed, of which 3 crops in land numbers exceeded the food heavy metal arsenic limit standard, and the soil XRF screening results did not exceed the soil pollution control standards in edible crop farmland; 40 specific plantings of edible crops have been completed The XRF screening operations at the base showed that the screening results were all lower than the soil pollution monitoring standards for edible crop farmland.
8. Soil and water conservation publicity activities and briefings, as well as promoting the installation of solar photovoltaics and promoting green and sustainable renovation
Completed 2 regulatory publicity briefings, 2 seed teacher training and campus publicity activities, 3 BMPs inspection meetings, optoelectronic equipment matching meetings and purchased promotional materials.
9. Emergency response and handling of public complaints
Completed 1 emergency response operation, and the soil test results were all lower than the soil pollution control standards.
