The progress of the work program completed by the work team as of the end of the reporting period in December 2003 was summarized as follows:
1, Xiangshan District, 19 mouth field monitoring wells, abundance, dry season test results:
(A) the dry season commissioned by the United States and the United States and Ying-chen technology testing analysis, Yingguo scientific and technological analysis results only Wu Pu Road 568 Lane lead more than the control standards.
(W102-03 Chinese roadside) total organic carbon over groundwater monitoring standards; abundance and dry season, there are 8 monitoring wells in the dry season, there are seven monitoring wells ammonia nitrogen exceeded groundwater monitoring standards; There are seven monitoring wells in the dry season, and there are seven monitoring wells with more than groundwater control standards.
(C) volatile organic pollutants in the dry season test did not exceed the control standards, including 1,1-dichloroethylene 1,1-dichloroethane, cis-1,2-dichloroethylene, chloroform, trichlorethylene ( The highest for the F010 Oxford Road 568 Lane 0.0362 mg / L), toluene and tetrachlorethylene were detected. The results of the wetting period show that the measured value of the trichlorethylene in the 374 alley of the Wujin South Road is 0.0887 mg / L exceeding the control standard of 0.05 mg / L, F004 Xiangshan Park, F010 Wuantou Road 568 Lane, 207 South Road, Huaihe Road and Hakone Motels and other four monitoring wells have been measured but did not exceed the control standards.
Second, the scientific industrial park 21 mouth field monitoring wells detection, abundance, dry season test results: Feng dry season monitoring results are lower than the regulatory standards.
(1) monitoring results in the area: five monitoring wells in the dry season exceeded the groundwater monitoring standard; three monitoring wells exceeded the groundwater monitoring standard; the VOCs concentrations did not exceed the control standards, but chloroform, trichlorethylene, tetrachlorethylene, Benzene and xylene project are measured in a small amount of concentration, the park all the way, bamboo village road, meditation lake and experimental secondary school chloroform, trichlorethylene have measured. There were 7 monitoring wells in the wet season exceeding the groundwater monitoring standard; there were 6 monitoring wells with more than groundwater monitoring standards; VOCs concentrations did not exceed the control standards, but 1,1-dichloroethylene, chloroform, trichlorethylene, tetrachloro Ethylene project has detected a small amount of concentration, but does not exceed the regulatory standards.
(B) the results of monitoring the well pattern
1. Bamboo # 9, Bamboo # 10 and Bamboo # 12 monitoring wells are set in the school, and bamboo branch Hsinchu Park monitoring wells are densely populated areas, groundwater ammonia detection value of 0.47 ~ 24.6 mg / L , Exceeding the groundwater monitoring standard 0.25 mg / L.
2. Iron and manganese have 9 and 8 monitoring wells over groundwater monitoring standards.
The measured values of lead in the W100-2 Aimin Park and W101-1 Jinshan Street (Jifu Palace) were 0.123 mg / L and 0.106 mg / L, respectively, exceeding the groundwater monitoring standard 0.10 mg / L
4. VOCs concentration did not exceed the control standards, but W101-3 people enjoy the street, W102-11 wind and air, bamboo # 7, bamboo # 8, bamboo # 9, bamboo # 10 and bamboo Hsinchu Park (Hsinchu Sewage plant) monitoring results of trichlorethylene has a small amount of estimates, estimates may be affected by the proliferation of pollution sites in the scientific park, other chloroform, 1,1-dichloroethylene, trans-1,2-dichloroethylene, tetrachloro Ethylene, trichlorethylene, 1,1-dichloroethane, toluene and xylene and other projects are measured in a small amount of concentration.
Third, the national park gas station due to the Environmental Protection Agency "gas station soil and groundwater pollution investigation plan (seventh) (B)" detection of the National Park Station easy to find TPH concentration exceeded, and then set the standard wells, the test results in line with groundwater control standards , So transferred to the Environmental Protection Agency for follow-up monitoring, this year's groundwater are in line with regulatory standards.
Fourth, the education university as a result of the EPD to monitor the requirements of the Environmental Protection Agency continued monitoring, dry season monitoring wells groundwater VOC monitoring and analysis, monitoring results of chloroform 0.00148 mg / L, did not exceed the second type of regulatory standards.
5, benevolent section 920 area around the wells well sampling analysis, this year to monitor five wells, the results of VOCs projects are lower than the groundwater control standards.
Six, Ren love section 920 number in early July for two 30m geological drilling and two monitoring wells set.
Seven, benevolent section 920 to the end of November and early December to carry out four simple wells and groundwater survey sampling.
8, the project on the Science Park No. 19 monitoring wells groundwater pollution area of the five monitoring stations are both monitoring, the test results are lower than the regulatory standards.
Nine, the new Tongguo Iron and Steel Co., Ltd. high pollution earth has left, the plan on May 23 to carry out piling check, the results of heavy metals are lower than the soil pollution control standards.
10, Xiangshan gas station on June 30 for soil validation operations, soil verification points 6 points and groundwater 2 wells sampling analysis, the results of soil and groundwater pollution concentrations are lower than the control standards, but the pollution of the earth is still stacked In the station has not been approved by the approved pollution improvement program book processing, still continued to tube.
Eleven, the bright gas station has been on the June 27 soil validation operations, the soil verification point of 6 points and groundwater 2 wells sampling analysis, which is located in the oil tank and the fuel tank between the R02 TPH 4560mg / kg more than the soil pollution control standards, The concentration of WC02 and WC05 in groundwater benzene standard wells and simple wells were 0.257 mg / L and 0.295 mg / L, respectively, exceeding the standard of groundwater pollution control 0.05 mg / L.
12, in order to strengthen the people and the industry soil and groundwater conservation concept, in May with the Environmental Protection Agency net Creek activities, the scene to posters, prizes and quick answers and other means of soil and groundwater education education. And then on November 4, 2003 for the underground storage tank system briefing, invited the EPD petrol station to declare the system management unit, for the city of the tube industry for system reporting, operation and maintenance and common problems and two-way exchange.
Thirteen, completed the first half of the year, the second half of the monitoring wells to monitor a total of 176 wells and the monitoring of the current year to carry out the maintenance of 12 appearance maintenance, 8 internal functional maintenance and 16 well body photography, well photography in the borehole fouling Monitoring wells, and performing well operations to maintain monitoring wells.
SWB-01, SWB-02 and SWB-03 and Taiwan Wooden Corrosion Protection Co., Ltd. MW130001-02 (reset) and MW130001- 04 unloading wells and unsupervised monitoring wells.
15, the abolition of the management of agricultural land to track the survey, 4 pen on the number of buildings (can not sample), a total of 94 pen survey, 190 points. Of which Xiangya paragraph 0349 and other 9 to the number of chromium, nickel, zinc and copper and other crops over the agricultural land control standards.
