The present invention relates to a soil sampling apparatus and a method for monitoring soil groundwater purification using the apparatus and a method thereof, and more particularly, to an adsorption module capable of easily separating or mounting a specific adsorption cell, And to a method for monitoring groundwater purification and in situ contamination characteristics using the apparatus.
The present invention was derived from a study conducted by the Ministry of Environment and the Korea Institute of Science and Technology as part of the project for the development of soil water pollution prevention technology. [Assignment number: The GAIA Project-2013000540005, Title: Development of evaluation and evaluation technology of soil and groundwater micro-environment for optimum pollution purification]
Recent rapid urbanization and industrialization have resulted in increased pollution of soil and groundwater. Various NT (Nano Technology), BT (Bio Technology), and ET (Environment) technologies have been developed to treat oil and heavy metal contaminants in contaminated soil around railway sites, Technology is being developed.
Prior to applying this purification technology, the first thing to consider is to accurately understand the characteristics of pollution and physical, chemical and biological characteristics of soil and groundwater contamination sites.
However, up to now, the scope and extent of pollution sources have been confirmed through a rough survey of soil and groundwater pollution. Many problems arise from the application of the purification method based on the simple index, which is the result of the outline survey, and there are many difficulties in applying the technology due to the very heterogeneous nature of the domestic soil and groundwater.
It is very difficult to observe the extent of contamination and the degree of pollution and to predict the behavior of the pollutants because of the underground nature of the pollutants in the environmental medium, which are invisible and complex and various structures. In addition, because it is controlled by various physical, chemical and biological characteristics of soil and groundwater, physical (density, permeability, water content, diffusion, flow rate, etc.) of soil and groundwater environment are predicted for prediction of pollutant behavior and successful soil / groundwater purification. , A sampling technique capable of accurately understanding the characteristics of a chemical (pH, electrical conductivity, redox potential, cation exchange capacity, organic carbon / nitrogen, organic matter content, etc.), biological (microbial species / community distribution, biomass amount, etc.) have.
Conventionally, sampling of soil and groundwater samples at the stage of starting the purification business follows a formalized method. In order to quantitatively evaluate soil pollution level (pollutant type, contamination range, etc.) in soil, Method, depth of sampling, sampling and storage of the sample.
The sampling points are selected based on the three-dimensional distribution of the target soil contamination considering the point where the contamination is confirmed, the point where the contamination is likely to occur, the hydraulic lipid condition, and the like. After the selection, samples are taken based on seven depths of 0.5m, 1m, 2m, 3m, 4m, and 5m below the topsoil and topsoil. Sampling methods can be selected appropriately according to the purpose, but rotary, striking, And mechanical sampling methods are mainly used.
In situ soil sampling methods are available for striking, manual, and mechanical sampling methods. However, these methods are susceptible to external contamination or microbial contamination. There is a problem in that it is not possible to use the existing borehole and it is inefficient and uneconomical to drill another ball every time.
In addition, due to the inhomogeneity of the underground environment, the pollutants and physico-chemical properties of the soil obtained even in the case of newly drilled in the vicinity are different from those in the samples obtained in the drilled holes, It is necessary to develop a sampling technique for analyzing the soil and groundwater environment without disturbing the pollution purification site.
Especially, it is necessary to develop a sampling technique that can reflect on - site conditions and analyze physical and chemical characteristics during or after the application of the purification method.

Most microorganisms adhere to the soil. Therefore, the microorganism irradiation method that performs the filtering after the conventional sampling of the ground water, which has been used for the investigation of soil and groundwater microorganisms, has a problem that most of the microorganisms attached to the soil can not be reflected.
Therefore, the present invention solves the problems of conventional soil and groundwater sampling, and devises a multi-core soil and groundwater sampling device and method using on-site media (in-situ filling material) for soil and groundwater sampling to represent the in- .
