Preliminary Investigation of the Decommissioning Site Environment (Soil, Groundwater) in the Storage Area of Anhui Jinbang Medicine Chemical Co., Ltd.

Basic profile:

The storage area of ​​Anhui Jinbang Medicine Chemical Co., Ltd. is located in the northeast of the intersection of Huancheng West Road and Yongyang West Road. The storage area was part of the Lai’an Grease Factory before 2009. It is mainly used for refining oil and storing edible oil. Since 2009, it has been the storage area of ​​Anhui Jinbang Pharmaceutical Chemical Co., Ltd., which is mainly used as a metal sodium warehouse, a temporary storage site for hazardous waste, and a storage tank area.

In accordance with the country's further strengthening of the safety management requirements for the special development of chemical parks and chemical concentration areas, chemical companies outside the parks should move into the park in batches according to steps. Anhui Jinbang Pharmaceutical Chemical Co., Ltd. will relocate as a whole to the West Chemical District of Lai'an County to dismantle the existing production equipment, storage tanks, workshops and warehouses. Among them, the storage area is demolished first, and the plot has another purpose. Therefore, in accordance with relevant national regulations, the decommissioned production area and storage area need to be surveyed on the status of soil and groundwater pollution, and based on the survey results, it is necessary to determine whether the land needs to be repaired. This time, a preliminary investigation of the current status of soil and groundwater pollution in the storage areas that were first demolished was conducted.

In order to fully grasp the status of the soil and groundwater in the company's storage area, on February 20, 2020, Anhui Jinbang Pharmaceutical and Chemical Co., Ltd. commissioned Chuzhou Zhishuo Environmental Technology Development Co., Ltd. to carry out preliminary investigations of the decommissioning site environment (soil, groundwater) in the storage area. According to the "Soil Environment Management Measures for Industrial and Mining Land (Trial)", "Technical Specifications for Soil Environmental Monitoring", "Technical Specifications for Groundwater Environmental Monitoring", refer to "Technical Guidelines for Site Environmental Investigation", "Technical Guidelines for Site Environmental Monitoring", and "Key Technical Regulations for the Investigation of Suspected Contaminated Plots for Land Use by Industries and Enterprises (for Trial Implementation), etc. Chuzhou Zhishuo Environmental Technology Development Co., Ltd. conducted on-site surveys on March 10, 2020 and consulted relevant materials provided by the construction unit, and compiled Anhui Golden The preliminary investigation plan of the decommissioning site environment (soil, groundwater) in the storage area of ​​the State Pharmaceutical Chemical Co., Ltd., and on-site sampling was carried out from March 13th to 15th, 2020. On the basis of on-site survey, sampling and analysis, Chuzhou Zhishuo Environmental Technology Development Co., Ltd. compiled the "Preliminary Investigation Report on the Decommissioning Site Environment (soil, groundwater) of the Jinbang Pharmaceutical Chemical Co., Ltd. Storage Area."

Survey conclusions and recommendations:

1, conclusion

The survey results show that:

The average value of each monitoring index of soil monitoring in the storage area of ​​Anhui Jinbang Pharmaceutical Chemical Co., Ltd. is lower than the "Soil Environmental Quality Construction Land Soil Pollution Risk Control Standard (Trial)" (GB 36600-2018) screening value land limit, indicating that the current site The soil meets the land requirements for the construction school.

The monitoring results of groundwater samples in the storage area showed that the various index values ​​of groundwater were lower than the Class III standards in the "Groundwater Quality Standards" (GB/T14848-2017), indicating that the groundwater in the plot is not currently polluted.

2, suggestion

In the later stage of the site demolition, the "Technical Regulations for Pollution Prevention and Control of Enterprise Demolition Activities" should be strictly followed to prevent the demolition activities from polluting the original site soil and groundwater.

If new pollution is found in the later demolition process, it is recommended to stop the demolition immediately, and then conduct further site environmental investigation and risk assessment before deciding on the next step.
