Remediation
Oxidation/Reduction/pH Stabilization/Nutirents/Biologicals Relevant Soil and Groundwater Contaminants:
• Petroleum Hydrocarbons
• Polycyclic Aromatice Hydrocarbons (PAHs) • Solvents • Heavy Metals • pH altering chemicals Chemical injection is a remedial technology that Nichols Environmental has developed and used since the companies inception. The istar TM technology (in-situ treatment and remediation) is a patent pending delivery system for injecting various inoculants into the soil and groundwater at varying depths. Inoculants include oxidants, reducing agents, pH adjusters, oxygen/air, water, nutrients, and biological organisms. The technology can be used to remediate contamination below a concrete slab, around a tank farm or beneath a rail line without demolition - meaning minimal disruption to our client's daily operations. istar™ can be used as a stand alone treatment system, or to augment other remediation programs such as vapour extraction, dual phase vacuum extraction, bio-venting, pump and treat, and/or bio-piles; The technology provides an alternative for areas with complex, inaccessible or expensive contaminant problems by eliminating costs associated with excavating, hauling and landfilling or extended pump and treat programs. The istar™ treatment unit is a self-contained, trailer mounted, mobile unit consisting of pumps, compressors and stainless steel injection lances. Nichols Environmental has treated contaminated sites across Canada using this process, with the largest in-situ chemical oxidation program being completed in Alberta, covering an area of 7,000 m2 to depths of greater than 10 metres. |
