For the environmental sustainability, the program of “The Survey of Soil and Groundwater Contamination in Changhua county in 2021” has been advanced, which involves groundwater monitoring wells maintenance and groundwater investigation, farmland and non-farmland monitoring, storage tank management, to supervise and verify pollution remediation of contaminated sites, dealing with emergency cases, and administrative assistances. The plan had been executed from December 24th 2020 to November 30th 2021, and the results of implementation are summarized as follows: At first, the task of groundwater monitoring wells inspection has been implemented twice this year and there were totally 10 maintenance works finished. All slug tests of groundwater monitoring wells were completed, and seven purges and five foreign matter exclusion of monitoring well were implemented according to the slug test results. Besides, there were 2 monitoring wells surveys accomplished, the results iron and manganese concentrations over than Groundwater Pollution Monitor Standards and the others are less than Groundwater Pollution Control Standards. In addition, the work team explored 18 factories with pollution potential in Changhua County. According to the exploration, there were 8 plants chosen and sampled, and the results demonstrated 2 factories’ soil samples over the control standards. We surveyed 367 storage facilities and provided consultation. There were 187 farmlands finished sampling for regular monitoring, and the analysis results showed 6 farmlands exceeded Soil Pollution Control Standards. With respect to the mission of to supervise and verify pollution remediation of polluted sites, those sites had been examined at least bimonthly, and there were 19 listed sites completed verification and 4 sites sampled for regular monitoring. There were entirely 8 emergency cases implemented during plan period.
