    Chemical Remediation Using: ISCO Remediation and ISCR Remediation

    Remediation of contaminated soil and groundwater through the use of chemical reagents is effective for a variety of contaminants and geologic site conditions.  Landshark Environmental (LSE) has both the expertise and technology for a wide range of options including: In Situ Chemical Oxidation (ISCO Remediation) and In Situ Chemical Reduction (ISCR Remediation).

    The safe implementation of chemical oxidants requires specialized, compatible equipment and change management administrative controls.  We have the capabilities to mix oxidants in small batches or through bulk feed systems. We have also developed injection tool strings that minimize exposure to our operators during injection.  LSE has developed the unique capabilities to support you with dosing and distribution designs.  This ensures contact while taking into consideration oxidant residence times, kinetics and site hydraulics.  Our custom mixing and injection equipment offer safe and effective delivery for optimal contact with subsurface contaminants.

    Chemical reduction, either by itself or utilized in a combined biotic remedy, provides the reactivity and persistence needed for effective treatment of metals and solvents in both source areas and plumes. Due to the physical characteristics of these chemistries, delivery to the subsurface is accomplished through injection, emplacement or shallow mixing.  LSE has supported numerous projects associated with PFOS, PFOA and PFAS soil and/or groundwater contamination.
