Objective:

The overall objective of the present study is to use sonic energy provided by pneumatic transducers coupled with soil fracturing to enhance the remediation of volatile organic contaminants in-situ from soil and rock in the vadose zone. During the past few years, laboratory tests with a siren and a whistle have shown an enhancement for in-situ soil remediation. The whistle, in particular, has demonstrated a contaminant mass removal rate of 1000 percent more than the control. In addition, the time required to reduce an initial contaminant weight of eleven pounds in the bed to one pound was reduced by a factor of at least 7 with the whistle. These results suggest that remediation time can be reduced leading to substantial savings in operational costs. In addition, it is believed that the proposed in-situ sonic process will be an effective "polishing" technique for removal of residual contamination not accessible with current in-situ techniques and enable site owners to reach regulatory levels at difficult sites, in-situ.

The principal objective of the current study is to scale up the laboratory versions of the pneumatic transducers to full pilot scale and to perform definitive field tests. McLaren/Hart Environmental Engineers have agreed to cooperate in field testing of a site in Hillsborough, NJ containing trichloroethylene. The principal deliverable of this project will be the development of a full scale, operational, low cost, in-situ, sonic detoxification process. This study will provide the "leap" from bench scale to field scale which is a crucial step in technology development, training, and transfer.

In addition to the field tests, the laboratory studies will continue with the siren to investigate the effect of sonic frequency on the removal rate of the decontaminants.

Approach:

A laboratory prototype of the ultrasonic siren device was designed and constructed at NJIT, and is currently being utilized in bench scale tests. With some modification, this device can be converted into field use for the proposed pilot test. In addition, a second sonic device based on the Hartman whistle with no moving parts has been developed for bench scale and field test as an alternate design. The siren can operate at variable frequency, and is currently being tested in the laboratory to measure the effect of sonic frequency on removal rate of the contaminants. A laboratory prototype of the stem jet whistle was designed and constructed at Applied Ultrasonic Inc., Bethel, CT., and is currently being utilized in bench scale tests and in the field demonstration test. The whistle proved superior to the siren in our laboratory tests because it operated at a higher sound intensity, had no moving parts, and the sound energy is more focused. The initial field studies were, therefore, made using the whistle.

Expected Results:

Soil fracturing technologies, both pneumatic and hydraulic, coupled with Vapor Extraction have enhanced the remediation of soil contaminated with volatile organic compounds. Furthermore, ultrasound technology has been proven in a variety of industrial applications for enhancing both liquid phase and vapor phase reactions and in cleaning and drying operations. When remediating contaminated soil and groundwater at industrial sites, an in-situ approach is preferred. It is the least costly, and it also minimizes potential contaminant exposure routes. The effectiveness of in-situ remediation technologies is highly dependent on the transport characteristics of the geologic formation under treatment. In formations such as sand and gravel with high permeabilities, in-situ treatment can be highly successful. However, in-situ remediation in geologic formations containing silt, clay, or tight bedrock is more difficult due to the characteristics of low permeability and high adsorption potential of these geologic materials.

Thus, soil fracturing coupled with focused sonic energy and vapor extraction can enhance remediation of contaminated soil and can be a "polishing" technique to enable site owners to reach regulatory levels at difficult sites in-situ.
