At an industrial property in Orange County, California, a focused remediation effort addressed groundwater contamination caused by chlorinated solvents left behind by historical industrial activities.
Over a six-week period, the project targeted 21 injection wells, each 2 inches in diameter, distributed across the contaminated zone. These wells enabled direct delivery of the amendment mixture into the groundwater plume.
Our client selected a combined JRW Bioremediation amendment injection strategy that leverages biological processes to degrade contaminants directly within the subsurface. The Wilclear Plus amendment creates favorable conditions for SDC-9 microbes to transform harmful chlorinated solvents into harmless end products such as ethene and chloride ions.
Wilclear Plus: A proprietary amendment designed to enhance microbial activity by providing essential nutrients and electron donors.
SDC-9: A bioaugmentation culture containing specialized bacteria capable of degrading chlorinated solvents.
Throughout the injection effort, the Legacy Team extracted groundwater from multiple onsite wells using submersible pumps for use as mix water, which was stored onsite in totes.
A portion of the extracted groundwater was treated with Newman Zone OS to create anaerobic conditions required for the SDC-9 bioaugmentation process.
All substrate mixing occurred within one of Legacy’s self-contained injection trailers. This mobile unit provided a controlled environment for the consistent and safe preparation, injection, and tracking of the amendment mixture.
To maintain a safe and secure worksite and to make the field effort less conspicuous to tenants, the Legacy Team installed fencing with privacy screening around the injection trailer, tanks, and equipment.
This project represents another successful effort completed by Legacy Remediation. By using groundwater as the mix and dilution water, the approach added very little volume to the aquifer while also enhancing distribution of the amendment mixture.
