Global regulatory drivers

PFAS are increasingly recognised as a global concern and priority. Regulatory frameworks are accelerating across regions to address their persistence and potential human and environmental impacts.

The European Union continues to advance coordinated restrictions and monitoring through the Drinking Water Directive and REACH processes, while the United States is advancing federal standards through the US EPA alongside varied state-level limits. Canada applies national health and environmental guidelines supported by provincial controls, and Australia implements national guidance for site assessment and remediation.

Across markets, recognised analytical standards – including ISO methods and US EPA reference methods – are essential to help ensure reliable, comparable and defensible PFAS data.

FAQ

PFAS (per- and polyfluoroalkyl substances) comprise a large class of fluorinated organic chemicals characterised by strong carbon–fluorine bonds, which make them highly persistent in the environment. Their mobility, potential for bioaccumulation and association with adverse health outcomes have led to increasing regulatory control in drinking water, environmental media, consumer products and industrial applications.
Our analytical scope includes more than 80 individual PFAS, covering long-chain and short-chain perfluoroalkyl acids (PFAAs), precursors, fluorotelomer-based substances and replacement chemistries. Compound lists are continuously reviewed and aligned with regulatory frameworks such as EU REACH proposals, US EPA priority listings and national monitoring programs.
We provide PFAS determination in a wide range of matrices including drinking water, groundwater, surface water, wastewater, soil, sediment, biota (tissue/blood), food, consumer products, industrial intermediates and process materials. Method selection and preparation are matrix-specific to help ensure accuracy and minimise interferences.
PFAS sampling requires strict contamination control. We supply matrix-appropriate sampling kits, certified containers and documented field protocols. Materials that may contain PFAS, including certain PTFE-based components, waterproof clothing and sampling tubing, must be avoided. Chain-of-custody procedures and field blanks are recommended to help ensure data defensibility.
Analyses are performed using LC–MS/MS protocols aligned with recognised standards such as ISO methods and US EPA reference methods (including EPA Method 1633, where applicable). All testing is conducted under ISO/IEC 17025 accreditation with full QA/QC, including calibration verification, matrix spikes, laboratory blanks and control samples.
Achievable limits vary by compound and matrix. For water matrices, method detection limits are typically in the low ng/L (ppt) range. For solids and biota, limits are generally in the ng/g (ppb) range. Detection levels can be tailored to meet regulatory thresholds or project-specific decision criteria.
Turnaround times depend on matrix type, analyte list, sample volume and reporting requirements. Standard lead times are offered, with expedited analysis available for priority investigations, compliance deadlines and incident response scenarios.
Yes. We offer data evaluation relative to regulatory criteria, guideline values and site-specific action levels. Interpretation can include temporal trend assessment, mass distribution profiling, precursor/transform analysis and lines-of-evidence evaluation to support site characterisation and risk management.
We support both discrete investigations and multi-phase monitoring programs, including sampling coordination, logistics, large dataset management and reporting standardisation across client assets or geographical regions.
