AST Environmental delivers specialized remediation services for per- and polyfluoroalkyl substances (PFAS), addressing impacts to soil, groundwater, and surface water at industrial, municipal, and military sites. Known for their persistence and mobility, PFAS compounds require precise characterization, proven mitigation technologies, and careful regulatory navigation to achieve effective, long-term results.
High-Resolution Site Characterization
PFAS remediation starts with understanding the full scope of contamination. Using our Remedial Design Characterization process, we integrate historical data with high-density sampling of soil, groundwater, and surface water. This data is compiled into a Quantitative High-Resolution Conceptual Site Model, identifying contaminant sources, transport pathways, and potential receptors to guide targeted approach.
Proven PFAS Treatment Technologies
AST designs and implements PFAS remediation strategies using field-proven products and delivery methods, including:
- FLUORO-SORB® – A specialized adsorbent media engineered to bind and immobilize a broad range of PFAS compounds from groundwater and soil.
- Permeable Reactive Barriers (PRBs) – Installed to intercept and capture migrating PFAS plumes, protecting downgradient receptors and property boundaries.
- In-Situ Remediation – Direct emplacement of treatment media in contaminated zones to immobilize PFAS and reduce leaching potential.
- Soil & Waste Excavation – Removal of highly impacted materials for secure offsite disposal when necessary.
Integration with Other Remediation Efforts
PFAS often co-occurs with other contaminants such as petroleum hydrocarbons or chlorinated solvents. AST can develop Combined Remedies to address multiple contaminant classes in a single remediation strategy, reducing project costs and timelines.
Regulatory Compliance and Documentation
Our PFAS remediation services are designed to align with evolving state and federal standards. We provide detailed reporting to satisfy regulatory agencies, support litigation or insurance needs, and facilitate site reuse or redevelopment.
Protecting Communities and Resources
From industrial discharge sites and landfills to fire training areas and airports, AST’s PFAS remediation projects are built on data-driven designs, precise reagent delivery, and rigorous field quality control. Our solutions safeguard drinking water sources, protect ecological systems, and restore impacted land for safe, productive use.
