What we’re doing
At SCG Remediation Services, we specialize in advanced in-situ injection techniques to remediate contaminated soil and groundwater plumes. Our tailored solutions effectively address a wide range of pollutants, from petroleum hydrocarbons (PHCs) to chlorinated solvents, ensuring environmental safety and regulatory site closure across various commercial and industrial industries.
Our team employs state-of-the-art in-situ remediation methods designed to treat contaminants directly within the subsurface environment, whether in overburden soils or fractured bedrock. These techniques minimize surface disruption and are cost-effective alternatives to traditional excavation or long-term pump-and-treat systems.
Our Chemical Injection Techniques
Custom-tailored injection solutions designed to meet your project life cycles, reducing risk and liability.
Carbon Injection and Permeable Reactive Barriers (PRB)
Ideal for treating dissolved-phase plumes from petroleum hydrocarbons or chlorinated sources, our carbon injection services use colloidal and non-colloidal carbon amendments. By forming a permeable reactive barrier (PRB), we “trap and treat” contaminants, allowing them to break down over time without migrating off-site. The barrier is strategically placed downgradient of the contamination source, aligning with groundwater flow for maximum efficiency and long-term plume management.
Biochemical Injection and Enhanced Bioremediation
Our biochemical injection involves introducing cultured microorganisms, electron donors, and nutrients into the contaminated environment to enhance anaerobic or aerobic bioremediation. This method promotes the propagation of bacteria that naturally degrade pollutants. Often utilized alongside carbon barriers and nutrient loading, success is measured through bench-scale testing, pre- and post-injection analytics, and ongoing monitoring of contaminant levels.
In-Situ Chemical Oxidation (ISCO)
We employ in-situ chemical oxidation (ISCO) by injecting powerful oxidants like permanganate, persulfate, or hydrogen peroxide into the subsurface via direct-push technology or permanent injection wells. This process rapidly breaks down a wide range of contaminants, including chlorinated solvents (such as TCE and PCE) and petroleum hydrocarbons. Selecting the appropriate oxidant is crucial, as not all compounds respond equally to every oxidant. Our experts tailor the oxidant choice to specific site conditions, soil lithology, and contaminants.
In-Situ Chemical Reduction (ISCR)
Utilizing in-situ chemical reduction (ISCR), we deploy chemical reductants such as zero-valent iron (ZVI) or proprietary materials to transform contaminants through abiotic reactions. Effective for treating chlorinated compounds and halogenated dense non-aqueous phase liquids (DNAPLs), ISCR addresses both soil and groundwater contamination comprehensively, often providing long-lasting treatment for stubborn source zones.
