Study Of Sampling About Treatment In Soil Contaminated By Volatile Organic Compound

China's rapid economic development brought about the unexpected deterioration of the environment in recent years. The contaminated soil and groundwater have a direct impact on our healthy. Our country is also focusing on the pollution of soil and groundwater. Investigate the polluted soil, define the scope of the contamination, survey the geological conditions of the pollutants is necessary before rehabilitating the contaminated soil and groundwater. We could have a remediation by physical, chemical and biological methods due to the survey. We could monitor and track the pollutants during and after remediation. So we acquire the effect of the soil cure engineering. Typically, sampling and indagation in polluted soil is the key in the remedion.Combine with drilling engineering, and soil environment monitoring and rescuing, it's indispensable to do some research in sampling. This paper rely on the horizontal wells in the soil solution-oriented pollution control method. Arming at the volatile organic contamination in soil, introducing the soil vapor extraction which inosculates physical, chemical and biological methods. Drilling rigs and tools, technics applied in sampling in China and other countries is specialized in this article too. Otherwise, we could upgrade this sampling technique to construct monitoring well. Design the sampling drilling tools came after the comparison of many tools. These tools could pick up soil, ground water and gas. They could have sample in horizontal direction as well. We test these drilling tools in fieldwork after manufactured. These tools is good at in sampling. However, we find some problems about them. We hope to do something to consummate them.
