The project has conducted the following items: 1.Groundwater Monitoring Wells: (1)218 wells had been inspected twice in 2019. (2)Various maintenance and repair had been completed. 2.Laws and technical seminars related to the prevention of soil and groundwater pollution : 12 briefings on laws and regulations, storytelling activities on elementary school campuses ,and seed lecturer meetings have been held in 2019. Two additional high school seminars had been held this year. The participation of high school students did have better interaction and learning effects. 3.Four emergency response work on soil and groundwater pollution had been completed. (1)The waste sampling and testing results of the high-pollution potential factory investigation showed that total chromium and total lead in the extract of the waste exceeded the business waste identification standard. (2)The sediment of No.1209 in Yongzhen Section, which still exceeded the upper-limit quality of the bottom sediment. The results had been transferred to the destination business authority for source tracing according to rights. (3)The detection result of the leakage incident of associated oil production in Tiejianshan, the soil and groundwater had exceeded the control standard of Soil and Groundwater Pollution Remediation Law. The site was announced as a control site on May 16, 2019. The site ’s total pollution potential assessment (TOL) ) with a score of 1200 or more, it was announced as a remediation site on August 30 of the same year. (4)The sediment of No.798 in Water Plant Section, which did not exceed the upper and lower limits of quality of the bottom sediment. 4.Site Verification work: (1)There are 3 soil and 2 sediment samples of K10238 site have been analyzed, and there is no abnormal. This site is the second verification, and the related expenses are paid by the improvement unit. (2)There are 10 soil and 2 sediment samples of K10008 site have been analyzed, and there is one soil sample has been reached the monitoring standard of arsenic. (3)There are 25 soil samples in heavy metal pollution area and 25 soil samples in BTEX pollution area of K10247 site have been analyzed, and there is no abnormal. (4) There are 25 soil samples of farmland site(K10249,K10243,K10244,K10245,K10246) have been analyzed, and there is no abnormal. 5.Completed the source tracing and progress of polluted sites (set up 2 standard wells and perform sampling and analysis 4 times), and some of the measured results of the analysis results reached the groundwater pollution monitoring standards. 6.Investigation of high-pollution potential factories. The heavy metal arsenic S02 at the soil sampling point in Wuqi glass yard reached 84.8mg/kg, exceeding the soil pollution control standard by 1.41 times. It is recommended to announce the control site according to Article 12 of Soil and Groundwater Pollution Remediation Law. 7.Completed the survey of land use of the three businesses announced in Articles 8 and 9 of Soil and Groundwater Pollution Remediation Law, and there is no abnormal. 8.Completed the tracking of the underground storage tank system of 10 gas stations. Ther were two gas satation exceeded the pollution potential grading warning value. According to GC spectrum screening conditions and interpretation instructions, belong to B2 classification, should be included in the follow-up continuous monitoring and tracking list. 9.Additinal activities: completed 1 regulatory orientation and 2 promotional activities on campus(high school).
