ORIN utilizes two primary methods of in situ soil blending, rotary mixing and excavation. Generally speaking, in situ treatment of contaminants avoids regulatory challenges associated with removing soil from a site as well as cost savings associated with transportation and disposal. Use of a rotary mixer or excavator allows for continuous direct application of the treatment chemistry onto the contaminated soil as it is exposed. This control allows ORIN to dictate precisely where the treatment chemistry is applied to insure contaminant destruction. Further, available on site mobile laboratory services provide real-time confirmation of contaminant destruction, reducing the potential for over dosing or unnecessary treatment. ORIN’s proprietary mobile dosing trailers afford efficient and precise mixing of necessary treatment chemistries on site, delivering cost savings and on-schedule completion of in situ soil treatment projects.
