The 14th Five-Year Plan for the Prevention and Control of Soil and Groundwater Pollution in Guangzhou was issued

Recently, the 14th Five-Year Plan for the Prevention and Control of Soil and Groundwater Pollution in Guangzhou (hereinafter referred to as the Plan) was officially issued by the Municipal Bureau of Ecology and Environment
.
It is clearly proposed to carry out the investigation of the groundwater environmental status around key pollution sources, and by 2023, complete the groundwater environmental investigation and assessment of a number of industrial agglomeration areas, hazardous waste disposal sites and landfills led by the chemical industry; Strengthen the supervision and management of quality and safety in grain processing and operation, increase the intensity of grain sampling inspections, and dispose of grain with excessive heavy metals found through supervision and inspection or spot checks in accordance with relevant national and provincial policies, so as to prevent grain with excessive heavy metals from entering the ration market
.

Establish a centralized treatment and resource utilization and disposal center for contaminated soil

The goals put forward in the "Plan" are: by 2025, the city's soil and groundwater pollution sources will be basically controlled, the environmental quality will remain stable on the whole, and some parts will be improved, the safe use of agricultural land and key construction land will be consolidated and improved, and the people will be further guaranteed to "eat and live with peace of mind", and soil and groundwater environmental risks will be further controlled
.

In terms of soil pollution risk management and control, further clarify the status of
soil environmental quality.
From 2022, focus on contaminated arable land of edible agricultural products such as rice and vegetables, and cooperate with the province to carry out agricultural product encryption investigations
.
In accordance with the deployment of the province, cooperate in carrying out the investigation of the
land used by enterprises in typical industries and the surrounding soil pollution status.
Carry out the city's forest land soil survey, and cooperate with the establishment of Guangdong Province forest land soil information database
.
From 2022, according to the unified deployment of the country and provinces, select typical areas to carry out the analysis of the
causes of cadmium pollution in cultivated land.
Where the source of pollution has been identified, the relevant district shall formulate a work plan for source control (source cutting) and implement it
.

Continue to promote the prevention and control
of the sources of soil pollution.
In areas where permanent basic farmland is concentrated and around residential areas, schools, medical and elderly care institutions, avoid the establishment of new persistent organic pollutant enterprises
such as heavy metals and polycyclic aromatic hydrocarbons.
Combined with new-type urbanization, industrial restructuring and resolving excess capacity, orderly relocate or close existing enterprises
that cause soil pollution in accordance with the law.

It is strictly forbidden for grain exceeding the standard of heavy metals to enter the ration market
.
Strengthen the safety supervision and management of grain procurement, storage and policy-based grain management
.
Supervise and urge grain business operators engaged in grain procurement and storage activities to carry out testing of heavy metals in grain, establish grain quality archives, and implement a quality inspection system
for grain entering and leaving the warehouse.
Strengthen the supervision and management of quality and safety in grain processing and operation, increase the intensity of grain sampling inspections, and dispose of grain with excessive heavy metals found through supervision and inspection or spot checks in accordance with relevant national and provincial policies, so as to prevent grain with excessive heavy metals from entering the ration market
.

Explore a new model
of risk management and remediation of contaminated land.
Continue to promote the pilot demonstration of typical plots, explore the "environmental remediation + development and construction" model of polluted plots, carry out project pilots and gradually form an experience model
.
For plots that meet the conditions of "pure land development" and clarify the main body responsible for restoration and development, encourage the development entity to adopt the "environmental restoration + development and construction" model, improve the efficiency of project utilization, reduce the waste of resources, and achieve coordinated carbon reduction in pollution reduction
.
Promote the construction of a centralized treatment and resource utilization and disposal center for contaminated soil in Guangzhou, explore the formulation of environmental regulatory requirements for the centralized disposal of contaminated soil in different places, promote centralized closed-loop monitoring of contaminated soil remediation, and ensure environmental safety
.

Orderly implementation of groundwater pollution risk control and restoration

In terms of the prevention and control of groundwater pollution, carry out investigations
on the environmental status of groundwater around key pollution sources.
Focusing on chemical production enterprises and industrial agglomeration areas, landfills and hazardous waste disposal sites led by the chemical industry, promote the investigation and assessment of
groundwater environmental conditions.
According to the unified work deployment of the state and the province, by 2023, complete the groundwater environmental investigation and assessment of a number of industrial agglomeration areas, hazardous waste disposal sites and landfills led by the chemical industry; By the end of 2025, complete the investigation and assessment of the environmental status of groundwater from a number of other pollution sources
.

Establish a groundwater ecological environment management system
.
According to the national groundwater quality assessment points, analyze the environmental quality status of groundwater and check the surrounding pollution factors
one by one.
Where the water quality target requirements are not met due to non-geological background, a groundwater quality standard or maintenance (rectification) plan shall be formulated, and prevention and control measures and completion time limits
shall be clarified.
In accordance with the unified deployment of the state and provinces, promote the delineation of key areas for the prevention and control of groundwater pollution, gradually implement regional management and hierarchical prevention and control of groundwater environment, and clarify differentiated environmental management requirements
such as environmental access, hidden danger investigation, risk management and control, and restoration.
According to national and provincial requirements, implement the recording degree of key pollution discharge names for groundwater pollution prevention and control, and guide and urge enterprises to implement relevant statutory requirements
for groundwater pollution prevention and control.

Orderly implementation of groundwater pollution risk control and restoration
.
According to the deployment of the province, implement groundwater pollution risk management and control for chemical parks, hazardous waste disposal sites and domestic waste landfills where groundwater pollution exists, and prevent the spread of
groundwater pollution.
Explore groundwater pollution risk management and control and treatment and restoration models
in accordance with local conditions.
Strengthen the assessment and later supervision
of groundwater pollution risk management and control, and the effect of restoration.

Optimize the environmental monitoring network
.
Strengthen the monitoring of irrigation water in farmland, carry out long-term monitoring in irrigation areas of more than 100,000 mu, and increase the frequency of monitoring of irrigation water for safe use and strict control of cultivated land when necessary
.
According to the requirements of the state and the province, establish a groundwater environmental monitoring network combining regional supervision and "dual-source" monitoring, standardize the construction of groundwater environmental monitoring wells, strengthen the operation, maintenance and management of existing monitoring wells, and promote the management of groundwater "one map"
.
