Technology & treatment-train selection
Compare remediation options against source strength, hydrogeology, receptors, and regulatory drivers — and design the combination that actually fits the site.
PFAS remediation
PFAS remediation for contaminated soil and water
Independent, evidence-led support for the hardest contamination problem in the industry — from treatment-technology selection and feasibility testing to remediation design and defensible reporting.
The challenge
PFAS don't behave like other contaminants.
Their persistence and mobility make source zones at airports, fire-training grounds, and industrial sites a long-term liability — and conventional methods struggle, especially with mobile short-chain compounds.
The value of good PFAS work is not picking a single technology — it's matching the right combination of methods to the site, then proving it will hold up to scrutiny.
What we do
Specialist PFAS support, from first question to defensible decision.
Bench-scale testing & feasibility
Column and bench experiments to test desorption, mobilisation, and treatment performance before committing to a field programme.
Analytical interpretation
PFAS quantification, suspect screening, and data interpretation across soil, water, foam, and treatment streams — turning results into decisions.
Monitoring & site strategy
Conceptual site models, sampling and monitoring design, exposure pathways, and risk-based decision support for impacted sites.
Fate & transport modelling
Contaminant transport, desorption, and mass-balance modelling to support remediation design and scale-up from bench to field.
Regulator-facing reporting
Clear assumptions, transparent interpretation, and recommendations a technical team, regulator, or project board can act on.
Treatment methods we assess
The full PFAS toolkit — matched to your site.
Aquentis evaluates and combines these approaches rather than defaulting to any one of them.
Air sparging with foam capture
In-situ mobilisation of surface-active PFAS from saturated source zones, with foam as a dedicated capture pathway.
Foam fractionation
Concentrating PFAS from water by air–water interfacial enrichment, reducing the volume that needs destructive treatment.
Soil washing
Ex-situ source treatment to separate and concentrate PFAS mass from excavated soil.
Granular activated carbon & ion exchange
Adsorption and polishing for treated water, with media selection informed by chain-length and matrix.
Pump and treat
Hydraulic containment and above-ground treatment where plume control is the priority.
Phytoremediation
Nature-based uptake as part of a longer-term or lower-intensity management strategy.
Destructive treatment of concentrates
Evaluation of destruction options for the concentrated streams that separation technologies produce.
Short-chain polishing
Dedicated steps for the mobile short-chain PFAS that ride with water and evade foam capture.
Research-backed
Grounded in peer-reviewed PFAS research.
Our recommendations are built on published, open-access research — including a controlled column study on air sparging and foam fractionation for AFFF-impacted soil.

Who we work with
Specialist PFAS input, wherever the site is.
Aquentis works with international clients — site operators and industry, engineering consultancies needing specialist PFAS depth as a subcontractor, and regulators and agencies building guidance and reviewing evidence.
