Sonic validates PCB destruction process in regulatory tests

PCB in soils remediated to less than 2 ppm using Sonic's proprietary technology)

CANADA, Jun. 21 -/E-Wire/-- Adam Sumel, President and CEO of Sonic Environmental Solutions Inc. (SNV.TSX Venture) is very pleased to report that all tests conducted as part of the regulatory approval process for the BC Ministry of Land, Water and Air Protection (Ministry) resulted in the successful remediation of Polychlorinated Biphenyl (PCB) contaminated soil samples to residual levels of less than two parts per million (less than 2 ppm PCB). These results will be incorporated into a formal report to the Ministry to assist them in the consideration of our request to commercially deploy Sonic's proprietary PCB destruction process.

Sonic conducted four (4) tests which were independently witnessed by URS Corp. consultants and staff from the Greater Vancouver Regional District (GVRD). These tests were conducted to demonstrate the efficacy and environmental performance of Sonic's proprietary process for the remediation of PCB contaminated soils. The efficacy of our process was confirmed by analysis of the PCB levels in the soil samples before and after our process treatment utilizing Sonic's PCB destruction facility. The four tested soil samples were from a PCB contaminated site in British Columbia and all had initial PCB levels in excess of 400 ppm PCB. These were all successfully remediated to less than 2 ppm using Sonic's proprietary PCB destruction process. Cost-effective destruction of PCB in contaminated soils to less than 2 ppm without the use of high temperature incineration is a breakthrough in environmental remediation.

The first of the four tests was conducted as a scoping test to allow Sonic to determine a test methodology for the analysis of any potential air emissions from our process. Sonic's air emission permit from the GVRD required the Company to measure and report air emissions and at the anticipated low levels of emission from the Sonic process, the monitoring method had to be confirmed. Results from the scoping test confirmed acceptable air emissions in an abbreviated analysis. Air emissions from subsequent testing will be independently analyzed in more detail and reported to the GVRD and the Ministry.

Sonic will also test and report on process water and solvent used in our tests in order to confirm final design criteria for treatment and disposal of these materials. These materials were re-circulated and re-used in all four tests. Initial results confirm that all used solvent had PCB levels below the analytical detection limit of 2 ppm.

Adam Sumel stated "Sonic's proprietary PCB destruction process using our patented Platform Technology has now been demonstrated under the most rigorous conditions. We expect to have all the results ready to report to the Ministry within a month. Now that we have completed these regulatory tests we can concentrate on process and design optimization of Plant Two, which will be deployed commercially later in the year. Although Sonic has met many significant milestones in the last three years, this is the independent validation that many potential clients and investors have been anticipating."
