Remediation engineering has made substantial progress since the days when the only option was removal and disposal. Excavation can still be the right choice for some sites, but when logistics are difficult, ground disturbance is undesirable, time is short, or the cost-benefit is not there, SoundEarth can apply any one of an array of innovative technologies with demonstrated success in targeted, site-specific applications.

To remediate petroleum or chlorinated compounds, consider in-situ chemical oxidation, which involves injecting oxidizing compounds into the subsurface to react with the contaminants. For example, at a dry cleaning site where chlorinated solvents are of concern, treatment with permanganate or other oxidizers may be cost-effective technology and could potentially clean up a property over a period of months instead of years.

Biological processes are also an option. Enhanced reductive dechlorination may be as effective as chemical oxidation at removing chlorinated compounds—the application time line is longer, but the capital costs are smaller.

Consider this: SoundEarth Strategies recently designed a remedial system that uses in-situ oxidation with temperature (actually heating groundwater) as a catalyst to address a Washington State Dangerous Waste (PCP) at a cost that is only 2% of the original multimillion-dollar estimate for remediation. Although excavation still offers more certainty than any other remediation technology—it is inherently subject to fewer unknown variables—these new technologies can provide powerful results and cost savings that make them well worth evaluating.
