Under the conditions used in these experiments, the use of low-level energy acoustic energy did not result in improvements in the biodegradation of PAHs in a PAH-contaminated soil compared to an untreated control. Expected impacts on biodegradation rates by the acoustic energy could not be evaluated as the data were not conducive to this determination. The acoustic energy was only supplied to the treated samples during 10 minutes per day (0.6944 % of a day). It is possible that using longer treatment times, more exposure to the acoustic energy, and alternate types of contamination might have been able to demonstrate the purported ability of acoustic energy to desorb nonpolar contaminants and improve their biodegradation rate and endpoint
