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 or immobilize petroleum hydrocarbons without excavation:
In-Situ Remediation with site-specific reagents to promote rapid contaminant breakdown including:
- Overburden Injection to target dissolved-phase hydrocarbons 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 petroleum impacts before reuse or disposal
- Environmental Construction to restore site conditions after excavation and treatment
Contaminants Treated
Our oil and gas spill remediation programs address:
- Gasoline range organics (GRO)
- Diesel range organics (DRO)
- Crude oil and refined petroleum products
- Benzene, toluene, ethylbenzene, xylenes (BTEX)
- Polycyclic aromatic hydrocarbons (PAHs)
Regulatory and Industry Expertise
AST has completed petroleum remediation projects under state and federal cleanup programs, as well as for private oil and gas operators, pipeline companies, and fuel distribution 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 tanker spill or remediating long-term petroleum contamination at a bulk-storage facility, AST delivers cost-effective, technically sound solutions that meet cleanup goals and protect environmental resources. Our combination of field expertise, advanced remediation technologies, and rigorous quality control ensures reliable results for even the most challenging oil and gas spill scenarios.
