Introduction
PFAS testing has become one of the most critical environmental and public health concerns in North America and worldwide. Per- and polyfluoroalkyl substances (PFAS), often called “forever chemicals,” persist in the environment and accumulate in living organisms, raising serious health concerns. With increasingly stringent regulations from Health Canada, the EPA, and international bodies, accurate PFAS testing is no longer optional—it’s essential for compliance, risk assessment, and public safety.
Per- and polyfluoroalkyl substances (PFAS) are synthetic chemicals extensively used in various industrial and consumer applications. While their stability and resistance to degradation make them valuable, these properties have also led to their classification as “forever chemicals.” PFAS contamination poses significant environmental and health risks, prompting stringent regulatory oversight. Accurate PFAS testing is critical to ensure compliance with environmental regulations and safeguard public health.
In this comprehensive guide, we will delve into the essential aspects of PFAS testing and explain why choosing the right laboratory is crucial for long-term success in your project. We’ll also highlight why ResolveMass Laboratories Inc. is a leading choice for PFAS testing in Montreal, Canada, the United States, and internationally.

1: What Are PFAS?
PFAS are a large group of synthetic fluorinated compounds known for their strong carbon-fluorine bonds, which confer exceptional chemical and thermal stability. Common PFAS include:
- PFOA (Perfluorooctanoic acid)
- PFOS (Perfluorooctanesulfonic acid)
- GenX chemicals
Sources of PFAS
- Industrial Processes: Used in non-stick coatings, stain repellents, and firefighting foams.
- Consumer Products: Present in textiles, food packaging, and cosmetics.
- Environmental Contamination: Found in soil, groundwater, and air due to industrial discharge and landfill leachate.
Health and Environmental Impact
PFAS exposure has been linked to various health risks, including:
- Cancer
- Hormonal disruptions
- Immune system impairments
- Developmental delays in children
Their persistence in the environment and bioaccumulation in humans and animals necessitate stringent PFAS environmental testing protocols.
2: Understanding PFAS: Why Testing Matters
PFAS are a group of over 9,000 synthetic chemicals that have been used since the 1940s in various industrial applications and consumer products. They include:
- PFOA (Perfluorooctanoic acid)
- PFOS (Perfluorooctanesulfonic acid)
- GenX chemicals
- PFBS, PFHxS, and many others
Health and Environmental Impacts
Research links PFAS exposure to multiple health concerns:
- Increased cholesterol levels
- Liver damage
- Thyroid disease
- Decreased fertility
- Increased risk of certain cancers
- Developmental effects in children
Because PFAS contamination affects drinking water, groundwater, surface water, soil, and even food products, comprehensive PFAS is critical for protecting public health and ensuring environmental safety.
Key Factor #1: Laboratory Accreditation and Certifications for PFAS Testing
The first and most important consideration is proper accreditation. A reputable PFAS laboratory should hold internationally recognized certifications that demonstrate competence and quality assurance.
Essential Accreditations to Look For:
| Accreditation | Significance | Geographic Relevance |
|---|---|---|
| ISO/IEC 17025 | International standard for testing laboratory competence | Global recognition |
| CALA (Canadian Association for Laboratory Accreditation) | Canadian laboratory quality standard | Canada-specific |
| NELAC/NELAP | National Environmental Laboratory Accreditation Program | United States |
| EPA Method Approval | Approval for specific EPA testing methods | U.S. and international |
| Health Canada Recognition | Compliance with Canadian health standards | Canada-specific |
Why accreditation matters: Accredited laboratories undergo rigorous third-party audits, maintain documented quality systems, participate in proficiency testing, and demonstrate technical competence. This ensures your PFAS results are defensible in regulatory proceedings and legal contexts.
Key Factor #2: Analytical Methods and Detection Capabilities
Not all PFAS methods are created equal. The laboratory’s analytical capabilities directly impact the quality and reliability of your results.
Standard EPA Methods for PFAS Testing:
- EPA Method 537.1: Drinking water analysis (18 PFAS compounds)
- EPA Method 533: Expanded drinking water analysis (25 PFAS compounds)
- EPA Draft Method 1633: Multi-matrix analysis (40+ PFAS compounds)
- Modified EPA 8000 Series: Soil, biosolids, and tissue analysis
Critical Detection Capabilities:
Modern PFAS laboratories should offer:
- Ultra-low detection limits: Capable of detecting PFAS at parts per trillion (ppt) or ng/L levels
- LC-MS/MS technology: Liquid Chromatography-Tandem Mass Spectrometry provides superior sensitivity and specificity
- Comprehensive compound coverage: Analysis of 20-40+ individual PFAS compounds, not just PFOA and PFOS
- Quality control measures: Method blanks, laboratory control samples, matrix spikes, and replicate analyses
Key Factor #3: Sample Matrix Expertise
PFAS contamination occurs in various environmental media, and each requires specialized testing protocols and expertise.
Common Sample Types for PFAS Testing:
- Drinking water and groundwater
- Surface water (rivers, lakes, streams)
- Wastewater and biosolids
- Soil and sediment
- Air and stack emissions
- Biological tissues (fish, wildlife)
- Consumer products and materials
The right laboratory will have documented experience with your specific sample type. Different matrices present unique challenges:
- Water samples require appropriate preservation and contamination prevention
- Soil samples need proper extraction techniques for accurate recovery
- Biosolids require specialized preparation to handle complex organic matter
- Tissue samples demand expertise in fat content and biological matrices
Ask potential laboratories about their experience with your specific sample matrix and request case studies or references from similar projects.
Key Factor #4: Turnaround Time and Capacity
Project timelines often depend on laboratory turnaround times, especially when regulatory deadlines or time-sensitive decisions are involved.
Typical PFAS Testing Turnaround Times:
Standard analysis: 10-15 business days after sample receipt Expedited service: 5-7 business days (usually at additional cost) Rush analysis: 3-5 business days (for urgent situations)
Important considerations:
- Turnaround time begins when samples arrive at the lab in proper condition
- Complex sample matrices may require additional time
- High sample volumes may extend processing times
- Holiday periods and peak seasons can affect scheduling
When evaluating laboratories, inquire about:
- Current workload and capacity
- Ability to handle your sample volume
- Flexibility for expedited requests
- Communication protocols if delays occur
Key Factor #5: Geographic Location and Logistics
Laboratory location impacts shipping costs, sample integrity during transport, and communication convenience.
Advantages of Choosing a Local Lab (Montreal/Canada):
