Ex Situ chemical treatment is accomplished by applying treatment chemistries to soils removed from the contaminated site and piled nearby or at a remote location.  Soils are mixed using a variety of earth moving equipment and mixing attachments.  Treatment chemistry can be applied simultaneously with soil mixing activities, or can be top dressed on static piles.  These application methods afford ORIN the capability to apply treatment chemistry in a precise manner, targeting contaminated soils directly.  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 cutting edge mobile dosing trailers afford efficient and precise mixing of necessary treatment chemistries on site, delivering cost savings and on schedule completion of ex situ treatment projects.
