Environmental survey method for underground water chlorohydrocarbon pollution

Abstract

The invention relates to the technical field of environmental investigation, and discloses an environmental investigation method for groundwater chlorohydrocarbon pollution, which comprises the following steps: S1, first-stage investigation is made; S2, result analysis is made: if a first-stage survey confirms that there is no possible pollution source in a working area and a surrounding area currently and historical, the survey activity can be ended, and if the pollution source existing inside and outside the working area cannot be eliminated, the second-stage environmental survey is carriedout; S3, second-stage investigation and preliminary sampling analysis. According to the invention, geological and hydrogeological conditions of an investigation area are found in detail; pollution source distribution of an investigation area is found out in detail, types and components of concerned pollutants are determined, the spatial distribution range of main pollutants in soil and underground water is delineated, the pollution degree of the soil and the underground water of the investigation area is evaluated and subjected to risk assessment, and a scientific basis and data support are provided for next-step treatment, restoration and safe utilization work. Development of groundwater pollution dynamic monitoring.

Description

technical field [0001] The invention relates to the technical field of environmental investigation, in particular to an environmental investigation method for chlorinated hydrocarbon pollution of groundwater. Background technique [0002] Water pollution is the reduction or loss of the use value of water caused by harmful chemical substances, water that pollutes the environment, acids, alkalis, oxidants in sewage, and compounds such as copper, cadmium, mercury, arsenic, benzene, dichloroethane, ethylene dichloride, etc. Alcohol and other organic poisons will poison aquatic organisms and affect drinking water sources and scenic spots. However, the water pollution situation in some cities is not optimistic enough and needs to be investigated in detail. [0003] If the detailed investigation and risk assessment of groundwater pollution cannot be carried out, it is difficult to provide a basis for the remediation, safe utilization and scientific management of soil and groundwat...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides an environmental investigation method for groundwater chlorinated hydrocarbon pollution, mainly to solve the existing difficulties in providing basis for soil and groundwater treatment and restoration, safe utilization, and scientific management in the area. It is impossible to delineate the spatial distribution range of major pollutants in soil and groundwater; it cannot provide scientific basis and data support for the next step of treatment, restoration and safe utilization, which seriously affects people's lives.
