Because of the result of crops analysis were all lower than Sanitation Standard for Contaminants and Toxins in Food, the project didn’t analyze heavy metal of soil. 3) Completed collecting 19 area of high contamination potential sites. 4) Completed 2 times patrol of 16 monitoring wells, appearance maintenance of well number Z00016 and Z00075, facility repairing of well number Z00018, well condition assessment of well number Z00005, Z00077, and Z00093. 5) Monitoring 6 times of groundwater, and ammonia nitrogen of Z00077 were higher than groundwater pollution monitoring standards. 6) The project has completed detection gas in leak detection tube of Meisui gas station, the PID/FID result showed that leak detection tube number A04, A05, A06, A08 were higher than 500 ppmV. 7) The project has completed Meisui gas station and Zhongshan Gate gas station soil interstitial gas analysis, and the gas measured Methyl tert-butyl ether, benzene, toluene, ethylbenzene and xylene. 8) Completed 12 places of underground storage tank counseling and auditing, the result was as same as previous years. 9) Completed examined underground storage tank on-line return of third time in 2022, first time in 2023, and second time in 2023, only Dongyin Shuangzhu gas station didn’t do pipeline sealing test in time, and has had repair. 10) Completed 2 places, including Taipower Zhushan unit and Nangan complex building of CHT, ground storage tank system improve tracking and review, both of the places conform to regulations 11) Completed one announcement of business land verification of the Zhongshan Gate gas station, and the results show that the total petroleum hydrocarbons (TPH) are all higher than the soil pollution control standards. 12) Completed 4 soil and 4 irrigated water sampling of farm soil steady monitoring, and 1 irrigated water re-sampling. The result showed all of them were lower than standard. 13) Three of underground storage tank near, Z00018, Z00092, and Z00093, had sampling groundwater. The result showed that Z00018 and Z00093 have TDS, Cl-, SO42-, total hardness higher than standard, and Z00092 has ammonia nitrogen higher than standard. 14) Completed 1 time information session and 1 place examining of team B, and 1 place examining of team C. 15) Completed 8 sites patrol with 1 time each month, and 6 sites verified. The result showed 2 of them did not pass. 16) Completed 3 publicity briefing session on storage system laws and regulations, 1 training session for seed instructors and 3 publicity briefing sessions on good land management personnel. 17) Negotiation matters - The groundwater sampling and analysis of Houwo Reservoir has been completed 1 time each season. 18) Negotiable matters - the inspection of 16 monitoring wells in the first and fourth seasons has been completed. 19) Emergency Response - Simultaneous sampling of site verification of Beigan abandoned gas station have been completed. 20) The first to fourth quarter quarterly reports and the military site contact meeting have been completed.
