The project period spans from January 1, 2021 to December 20, 2021. The results of three regular soil inspections revealed the arsenic and copper concentrations at four land numbers, including number 948, in the Jincheng section in Pingtung City to be lower than that of Soil Pollution Monitoring Standards. The regular groundwater inspection in the Xinkailiao region revealed no figure exceeding the Groundwater Pollution Monitoring Standards. The concentration of the pollutant concerned (i.e., the pollutant to be risk assessed), 1,1-Dichloroethene, exceeded the recommended baseline value of confirmation (0.006mg/L). For dug wells in the seven illegal dumping sites, one site with pollution potential, and the surrounding environment of these sites, no water quality inspection result exceeded the Groundwater Pollution Monitoring Standards.
This study completed external inspections on 328 monitoring wells (356 if including double-layered wells), maintained the appearance of 21 wells, repaired 5 wells, maintained the internal functions of 29 wells, and removed foreign objects from 5 wells. These wells were of satisfactory conditions after maintenance. In addition, the abandonment of 4 standard monitoring wells and 2 simple wells was completed.
For underground storage tanks, this study completed inspections on soil gas monitoring wells of 35 gas stations, among which wells at 4 gas stations with irregular concentrations of gasoline vapor. The soil gas in the well was collected in a gas sampling bag and subjected to a gas chromatography¬–flame ionization detection analysis. Jian Guo Gas Station’s pollution potential was determined to be at level A, and an inspection revealed no concern of pollution. No irregular concentration of gasoline vapor was observed for the other gas stations. On-site inspections were conducted on 282 gas stations; defects revealed in the inspections mainly involved the inconsistency between on-site conditions and those they reported online. Subsequent corrections were made when providing assistance to on-site operators, and functional inspection of soil gas monitoring wells yielded satisfactory results for all gas stations. Overground storage tank and container inspections were also completed at 107 sites, among which 17 were not under the scope of the management regulations; for the remaining 90 sites, improvement work was needed in 75 sites.
This study completed 13 verifications/inspections along with emergency response drills. Nine were confirmations along with emergency drills, and four were inspections, whose results were all lower than the inspection target.
In terms of administration and promotion-related tasks, this study offered 2 training sessions for seed teachers; held 12 on-campus promotion events; held 3 public meetings on relevant legal regulations; held 1 symposium on pollution inspection technology; held one nationwide conference for exchange on soil and groundwater pollution remediation efforts; published two press releases; sent out 300 picture books, 150 promotional gifts, and 150 promotional flyers; assisted in 4 audit meetings for the sites under monitoring; reviewed 8 site reports, 2 documents of management regulations for underground storage tanks, and 9 data reports published by businesses; and inspected sites on the monitoring list.
