Soil and Groundwater Contamination Investigation Project in 2013 Environmental Protection Bureau, Kaohsiung City

This project was contracted by the Environmental Protection Bureau of Kaohsiung City (Kaohsiung EPB) to control the soil and groundwater contamination in Kaohsiung. The scope of this project was to investigate and identify the soil and groundwater contamination in Kaohsiung, prevent the expansion of any contamination, and to conduct oversight and verification of gas station standard operating procedures. All of the work specified in the contract has been completed. In accordance with the contract, starting from April 2013, the soil and groundwater contamination webpage of Kaohsiung EPB was updated on the 5th of each month, so that the public can regularly receive new information and understand the effectiveness of the work performed. In addition, we continuously updated project content in the soil and groundwater information management system to reflect the status of every monitored site. In overseeing ongoing decontamination programs and verifying completed decontamination programs, we completed 349 points of soil sampling and 252 groundwater sampling, as well as 42 additional groundwater samples for TPH-d analysis and 12 additional groundwater samples for analysis of 8 metals. During this calendar year, we completed 17 site contamination investigations and 19 decontamination verifications, performed oversight of 8 sites with ongoing decontamination, and monitored the groundwater early warning systems at 5 industrial parks. During this year, we inspected the external appearance of 865 groundwater monitoring wells; any minor defects were immediately corrected on-site after the inspection. Twenty-five wells with external damage were repaired. Eleven wells had structural damage and were also repaired. Video inspections were performed on five wells. Seven standard monitoring wells were found unusable and removed from the monitoring list. Sixteen temporary wells and sixteen standard monitoring wells were installed. We hired a registered, qualified lawyer with the relevant expertise to provide legal consulting services in eight cases. Four training sessions in soil and groundwater pollution and remediation issues were held for EPB personnel. Three regulatory guidance meetings were also held to inform business and gas station owners about legally mandated soil and groundwater remediation practices. There were approximately 100 sites in Kaohsiung city; we inspected all sites once a month and assisted in the review of the various contaminated sites report, and provided a total of 115 review comments. We assisted the gas stations with their quarterly reporting, achieving a reporting rate of 100% for the first and second seasons, and also assisted in the review of four gas station equipment plans or completion reports. We completed 32 gas station inspections and preventive inspection work at 20 gas stations.
