The plan was signed on March 3, 105 and the implementation date was until 31 December 105. The total planned expenditure was NT $ 5,980,000. The program was staffed as a project manager, one engineer and one full-time assistant engineer 1; as of the end of October 2005 the implementation of the results are as follows:
First, groundwater wells water quality monitoring
The sampling and monitoring operations of this operation were completed in October 2005, including six riverside sports park and six riverside sports park 101 and other two wells detected chloroform and trichlorethylene in the dry season exceeded the control standard, the It was found that the raw material, process or waste contained trichlorethylene, and that the flow rate of the single well in 104 years could be found to be 76.6 degrees in the well of C00032 and in the well of C00033 The flow of 297.4 degrees, the flow of two wells of a difference of more than 220 degrees, presumably due to the location of the two wells in the corner of the Keelung River, the Keelung River turbulence may cause the slow movement of contaminants or even accumulated in the vicinity of C00032 wells, according to the concentration In this regard, the trichlorethylene is still in continuous slow degradation, and since the concentration of trichlorethylene in the C00033 has been reduced to 0.0005 in the peak period, it is judged that there is no continuous injection of contaminants, ; Other groundwater wells water quality sampling test results show that in addition to iron, manganese and ammonia nitrogen, there are no more than groundwater control and monitoring standards.
Second, monitoring wells maintenance
The operation was completed in November 2005, and the appearance of the 25-well monitoring wells was not significantly damaged. Eleven wells were replaced and a total of 10 re-paint operations were carried out. According to the well assessment results, The recovery rate of the two wells is increased, but the recovery rate of the six sewage treatment plants is still slow, suggesting that the geological environment may be caused by factors The The following are the same as the "
Third, soil and groundwater pollution site pollution remediation improvement during the supervision and inspection work
The project completed at least one of every two weeks of inspection work at Quan Yi Gas Station, Daewoo Iron ＆ Steel (Tai Wulun Factory) and Taizhuang Keelung Gas Station at the end of October. The site is in line with the specifications and remediation period.
Quanyi gas station remediation period until November 25, 105, although the concentration of pollutants has been substantially reduced, but still can not reach the approved date of the regulatory standards, the proposed industry to assess whether the excavation method for remediation, the work team continued Follow the inspection work.
The Environmental Protection Agency of Daewoo Iron ＆ Steel (Tai Wulun Factory) agreed to prepare the "Soil Pollution Control Plan (Finalized Edition)" at the site on November 3, 2003 and complete it within 24 months from the next day Remediation, including self-verification and submission of the completion of the completion of the report; the industry after the completion of remediation construction and self-verification, on October 15, 104 to the Keelung City Environmental Protection Agency proposed soil pollution control site completion report and apply for verification; (Cu) and total petroleum hydrocarbon (TPH) were detected by sampling at 5-point sampling from Dawu Iron ＆ Steel Co., Ltd. on November 2, 104. The maximum weight of copper (Cu) was 14.3mg / kg (Soil pollution control standard 400 mg / kg); total petroleum hydrocarbon (TPH) measured as ND (soil pollution control standard 1,000 mg / kg), 2 did not exceed the soil pollution control standards, the investigation site has completed pollution To improve the operation, it is recommended that the Environmental Protection Agency report on the results of the administrative procedures in the "Keelung City Soil and Groundwater Pollution Improvement Team" to explain the effectiveness of remediation, follow-up to follow the regulations to lift the tube.
During the implementation of the project, the Taizhuang gas station will perform the ground excavation, earth excavation, environmental monitoring, landfill backfill, pollution earthmoving and ground restoration during the implementation of the project, and completed on March 24, Self-verification work, the test results are below the soil pollution control standards below, then on April 29 to submit the necessary measures to improve the completion of the soil plan to complete the report, after the review of the work team is correct, in June to implement the entry verification work, The results showed that the total oil and hydrocarbon (TPH) measurements were ND at the 5-point soil test and did not exceed the soil pollution control standard (1,000 mg / kg). Follow-up procedure was to follow the procedure.
The following are the same as the "
Fourth, emergency response
April 27, 2005 by the people in the city under the new mountain reservoir (wheat road 715 Lane) land was abandoned to build the remaining earth and the mixture (including asphalt).
The site is located at the discharge below the embankment of the new mountain reservoir, near the tributary of the Great Wuling River. To check whether the remaining earthwork and the mixture (including asphalt) in the site cause soil pollution or toxic substances, the work team arranged for soil sampling operations.
The sampling operation was completed on June 3, 105, the test results show that the points are not volatile organic compounds and semi-volatile organic matter, only S02 and S05 have a trace of TPH value; in eight heavy metals, All the laws and regulations are in line with the standard value, follow-up will be related to the relevant administrative procedures.
5, underground storage tank declaration check
The team was completed in September 2005 this year, the gas station on the line to declare the declaration, no reporting overdue industry; and in October to complete the 21 sub-station site inspection operations, including seven gas stations, the success of all the way to the gas station and anchor The gas station in the first half of the PID and FID measured in the first half of the follow-up in the second half of the follow-up and the implementation of GC / FID detection, 3 stations are measured methane value, but n-decane, MTBE and BTEX are ND, Will be the national seven gas stations classified as pollution potential B2 level, every 3 months to track 1 times, for 3 consecutive times abnormal, the implementation of soil survey; successful all the way gas stations and anchorage gas stations classified as pollution potential B1 , Every 2 months to track 1, continuous 3 times abnormal, the implementation of soil water survey.
In the second half of the gas station check found in Xiangfeng Street gas station leak detection tube P16 measured PID value of 3,549ppmv and FID value of 68,500ppmv; implementation of soil sampling GC / FID detection, testing items in methane 19.5ppmv and xylene 10ppmv, others are ND, the proposed classification for the B1 level, every 2 months to track 1, continuous 3 times the exception, the implementation of soil water survey.
