Soil and Groundwater Treatment

Where project goals require in-situ treatment of contaminated media, OP-TECH successfully implements remedial measures involving the treatment of soil and groundwater through both new installations and modifications to existing treatment systems. OP-TECH has completed many innovative projects utilizing redox (reduction/oxidation), solidification/stabilization, soil vapor extraction and carbon scrubbing. 


OP-TECH 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 material suitable for land disposal or beneficial use.  These techniques have been used as both final and interim remedial measures.


OP-TECH has successfully performed in-situ remediation using chemical redox agents such as Zero Valent Iron (ZVI), Fenton’s Reagent, and RegenOx®.  The exact concentrations and specific agents are determined based on site specific factors such as geology, hydrogeology, contaminants, concentrations, current use and planned use.  OP-TECH typically uses direct push equipment to install well points for the introduction of the appropriate agent and monitoring progress. 
OP-TECH provides mobile water treatment systems for routine, scheduled service applications as well as dispatching them on an emergency basis.  The Company’s 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.


OP-TECH routinely fabricates and constructs integrated remediation systems configured to meet designed, site-specific cleanup criteria while satisfying air and/or water quality discharge standards. The Company’s integrated remedial systems address all aspects of surface and subsurface contamination as it exists in groundwater and soil.
