Soil Treatment & Remediation

RESOURCES › ADVANCED MATERIALS & ENVIRONMENTAL REMEDIATION

Restoring Ecosystems, Health, and Land Productivity

Soil remediation and treatment technologies restore contaminated soil and groundwater, converting impacted industrial, legacy energy, and agricultural sites back into productive, safe land. By integrating biological breakdown, chemical stabilization, and bio-based amendments, modern soil treatment mitigates environmental liabilities while protecting Louisiana's freshwater aquifers, working agricultural acres, and coastal watersheds.

Key Remediation Technologies & Pathways

Soil treatment approaches vary based on the specific contaminant matrix across three primary engineering domains:

Bioremediation & Phytoremediation

Leveraging specialized microorganisms or deep-rooted plant species to naturally degrade, absorb, or neutralize organic pollutants (such as hydrocarbons and solvent residues) directly in the soil matrix (in-situ) or in excavated treatment cells (ex-situ).

Chemical Oxidation & Immobilization

Injecting targeted chemical oxidants or specialized stabilizing agents to rapidly break down recalcitrant compounds or bind heavy metals into non-leachable, biologically inert forms.

Soil Flushing, Salinity Management, & Organic Amendments

Utilizing leaching agents, gypsum, and bio-based soil conditioners (such as biochar, compost, or processed organic solids) to reclaim soils degraded by high-salinity brine spills or industrial runoff.
