Qualitative analysis of macro-environmental factors affecting soil venting efficiency
- Ohio Univ., Athens, OH (United States). Dept. of Civil Engineering
The efficiency of any soil vapor extraction operation has always been related to micro-environmental factors such as vapor flow rate, vapor flow path, and contaminant distribution and composition. However, it is not clear to what extent macroenvironmental factors such as barometric pressure, rainfall, temperature, and water table affect the operation of soil venting systems. The majority of research conducted to this date involves short term tests (less than one week), and the analysis assumes that the macro-environmental factors are constant over time. To assess the importance of macro-environmental factors, long term tests are necessary. Field tests using air extraction in vertical wells are evaluated in conjunction with the macro-environmental factors. Seven venting wells were installed at an uncontaminated sandy site. An automatic data acquisition system was set up to record the change of those macro-environmental factors and the pressures in the venting wells. The primary method of this qualitative study is to conduct long term tests (weeks or months duration) such that the effect of the environmental change can be characterized during the test.
