103 Hsinchu soil and groundwater pollution investigation and verification work program
Absrtact |
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
