High-Resolution Site Characterization
Accurate data drives effective remediation. Using our Remedial Design Characterization process, we collect high-density soil and groundwater samples and evaluate hydrogeologic conditions to develop a Quantitative High-Resolution Conceptual Site Model.
In-Situ Treatment Options
AST applies in-situ remediation technologies to degrade and/or immobilize chlorinated solvent impacts without excavation.
In-Situ Remediation with site-specific reagents to promote rapid contaminant breakdown including:
- Overburden Injection to target dissolved-phase chlorinated solvents in unconsolidated soils
- Bedrock Injection to address impacts in fractured bedrock formations
- GeoTAP™ (Pre-Drill Methodology) for in-situ treatment of contamination in lithology that is difficult to access using direct push technology alone
- Permeable Reactive Barriers (PRBs) installed to prevent contaminant migration and protect downgradient receptors
Ex-Situ Cleanup Methods
Where direct removal is required, AST offers:
- Soil & Waste Excavation for heavily impacted source material
- Soil Mixing with chemical or biological amendments to treat chlorinated solvent impacts before reuse or disposal
- Environmental Construction to restore site conditions after excavation and treatment
Contaminants Treated
Our chlorinated solvent remediation programs address:
- Chlorinated ethenes
- Chlorinated ethanes
- Chlorinated methanes
- Chlorinated benzene
- Some pesticides and herbicides
- Wood treating chemicals
- Polychlorinated biphenyls
Regulatory and Industry Expertise
AST has completed chlorinated solvent remediation projects under state and federal cleanup programs, as well as for private clients that own dry cleaning or manufacturing facilities. We provide full documentation to meet regulatory requirements, support insurance claims, and facilitate site reuse.
Proven Outcomes
Whether cleaning up soil and groundwater impacts from a solvent spill or remediating long-term chlorinated contamination at a manufacturing facility, AST delivers cost-effective, technically sound solutions that meet cleanup goals and protect environmental resources. Our combination of field expertise, advanced technologies, and rigorous quality control ensures reliable results for even the most challenging remediation scenarios.
