Conceptual model Use words, diagrams, tables, etc. to systematically and comprehensively describe pollution sources, pollutant migration pathways, and exposure of the human body or ecological receptors to polluting media Process and contact methods, etc. 3.6 Receptor Environmental factors such as soil and groundwater in the assessment area and its surrounding environment that may be affected by environmental pollution or ecological damage, and People, biological groups and ecosystems. 3.7 Theoretical treatment cost The governance cost calculated by the governance cost function. The governance cost function takes governance costs as the dependent variable, and uses processing technology and processing Factors such as scale and pollutant removal efficiency are function models constructed by independent variables. When the concentration of pollutants and governance objectives are determined, the The above variables are brought into the governance cost function, and the corresponding theoretical governance costs can be obtained.4 Work content and procedures4.1 Work plan formulation Grasp the basic situation of ecological environmental damage involving soil and groundwater, and understand the natural environment and social conditions of the damaged area and surrounding areas; Preliminarily judge the damage scope of soil and groundwater, clarify the content of the ecological environment damage identification assessment involving soil and groundwater, and determine the identification Evaluation methods, preparation of appraisal and evaluation work plans. 4.2 Damage investigation confirmation Through conducting geological and hydrogeological surveys, soil and groundwater pollution status surveys, soil and groundwater ecological service function surveys, soil The baseline level survey of soil and groundwater environmental quality and its ecological service function, to determine whether the soil and groundwater environment and its ecological service function got damage. 4.3 Causality analysis Through pollution source analysis, migration and transformation process analysis and verification, analyze whether there is a relationship between environmental pollution behavior and soil and groundwater damage Causal relationship. By analyzing the mechanism of ecological damage caused by soil and groundwater damage, determine ecological damage and soil and groundwater damage Whether there is a causal relationship between harms. 4.4 Physical quantification of soil and groundwater damage and development of restoration plans Screen soil and groundwater damage assessment indicators to determine the extent and scope of damage. When the damaged soil and groundwater can be restored, the study determines the base For this restoration goal, formulate alternative basic restoration plans, estimate restoration time, calculate period damage, determine the scale of compensatory restoration, and formulate alternatives Compensatory restoration plans, conduct comprehensive comparison and selection of restoration plans, and determine the best plan. 4.5 Quantification of soil and groundwater damage value Based on whether the soil and groundwater damage has been restored, whether it needs to be restored, whether it can be restored, etc., the restoration cost method and actual Governance cost method, theoretical governance cost method, virtual governance cost method, resource value method and other environmental value evaluation methods Quantify. 4.6 Preparation of soil and groundwater damage assessment report Compile ecological environmental damage assessment reports (opinions) involving soil and groundwater, and establish a complete Water ecological environment damage identification and assessment work files. The evaluation of the effect of ecological environment restoration shall prepare an independent evaluation report of the effect of ecological environment restoration. 4.7 Evaluation of soil and groundwater restoration effect Regularly track the restoration of soil and groundwater damage and evaluate whether the restoration effect has reached the expected goal. When the expected goal is not reached, the design And implement a supplementary restoration plan; when it is judged by the risk assessment and other processes that no supplementary restoration is needed, the environmental value assessment method Should loss calculation. See Figure 1 for the identification and assessment procedures of ecological environmental damage involving soil and groundwater. In practice, you can appropriately simplify the The above-mentioned related work shall be carried out selectively. When necessary, special topics should be carried out in response to key issues in the assessment of ecological environmental damage the study. The basic situation of soil and groundwater ecological environmental damage, understand the natural environment and social conditions of the damaged area and surrounding areas, analyze the soil and ground The scope of possible damage to the launching water, clarify the main content of the ecological environment damage identification and assessment work involving soil and groundwater, and study to determine the assessment Specific methods of work, preparation of appraisal and evaluation work plans. 5.1 Basic situation survey a) Information related to the source of damage. pollution source, production history, production process and pollutant generation link, location, pollutant discharge, Stacking, landfilling and disposal areas, historical pollution accidents and their handling conditions; for environmental emergencies, the incident should be ascertained Time and location, the type and nature of pollutants that may be produced, the discharge amount (volume, mass), pollutant concentration, etc. Circumstances; for ecological damage incidents, understand the nature of the incident, damage mode, time, location and other basic information; b) Information related to the damage process. pollutant discharge method, discharge time, discharge frequency, discharge destination, characteristic pollutant category, concentration Degree, possible secondary pollutant type, concentration and other information and conditions; damaged forest land, cultivated land, grassland, wetland and other ecological The natural state of the system, as well as the time, method and process of damage to animals and plants; c) Information related to preliminary treatment and disposal. control measures such as pollutant clean-up, prevention of pollution spread, or relevant information on the implementation of ecological restoration measures Materials and conditions, including implementation process, implementation effect, cost and other related information; d) Historical and current monitoring related information. monitoring work development and monitoring data, including monitoring data of soil and groundwater environmental quality According to survey data such as the number, density, abundance, structure, community composition and structure of indicative biological species; e) The current status and recoverability of the ecological environment damage in the area where alternative restoration may be carried out. 5.2 Natural environment and socio-economic information collection Investigation and collection of natural environmental information in the assessed area, including. a) Topography, geomorphology, hydrology, climate and weather data; b) Geological and hydrogeological data; c) The history, current situation and planning information of land and groundwater utilization; d) The distribution of existing groundwater wells; e) Information on the distribution of environmentally sensitive areas such as residential areas, drinking water sources, ecological protection red lines, nature reserves, wetlands, and scenic spots Information and the distribution of major biological resources; f) Distribution of factories, mines, reservoirs, structures, ditches, underground pipe networks, seepage pits and other non-point source pollution.
