In-Situ & Ex-Situ Treatment

Clean Harbors has demonstrated experience in providing in-situ and ex-situ treatment systems.  Utilizing chemical oxidation, stabilization and solidification and mobile treatment systems, we provide solutions in the most challenging environments.

Chemical Oxidation

Clean Harbors provides chemical oxidation applications using peroxide (Fenton’s Reagent) and permanganate products, which cause the rapid and complete chemical destruction of many toxic organic chemicals.  Our experience includes direct in situ injection application, ex-situ or off-site applications for successful remediation of soil and groundwater.

Stabilization and Solidification

Clean Harbors provides soil solidification and stabilization applications, which reduce the mobility of hazardous substances and contaminants in the environment through both physical and chemical means.  Solidification and stabilization techniques are used alone or combined with other treatment and disposal methods to yield a product or material suitable for land disposal or in other cases that can be applied to beneficial use.  These techniques have been used as both final and interim remedial measures.

Mobile Treatment Services

Clean Harbors provides mobile treatment systems for routine, scheduled service applications or dispatches them on an emergency basis.  Our capacities range from 10 to approximately 500 gallons per minute and are available in a number of sizes and configurations. All systems are pre-assembled, self-contained, requiring minimal setup time upon mobilization, and are available as trailer-mount, skid-mount or containerized.
