What Are PFAS and Why Is Testing Important?
PFAS are a group of over 12,000 synthetic chemicals known for their resistance to heat, water, and oil. Commonly found in non-stick cookware, firefighting foams, and waterproof coatings, these “forever chemicals” persist in the environment and pose significant health risks.
Regular PFAS testing is essential because:
- PFAS can contaminate drinking water sources.
- Health risks include cancer, liver damage, and immune system disruption.
- New regulations demand precise detection and documentation.
ResolveMass Laboratories Inc. provides full-spectrum PFAS testing services, adhering to EPA methods (such as EPA 537.1 and EPA 533) and provincial compliance protocols. For complete details, view our PFAS testing services.
Most Common PFAS Testing FAQs – Answered by ResolveMass Laboratories Inc.
1. What types of PFAS compounds does ResolveMass test for?
ResolveMass tests for over 40 targeted PFAS compounds using LC-MS/MS (Liquid Chromatography-Mass Spectrometry). These include:
- PFOA (Perfluorooctanoic acid)
- PFOS (Perfluorooctanesulfonic acid)
- GenX chemicals
- Short-chain and long-chain PFAS
For a complete list of detectable compounds, review our PFAS method capabilities.
2. What is the detection limit for PFAS in water?
Our standard PFAS testing method achieves detection limits in the low parts-per-trillion (ppt) range—often below 2 ppt. This sensitivity is crucial for compliance with Canadian and U.S. health advisories.
3. How are PFAS samples collected?
Samples must be collected using PFAS-free containers, with no Teflon, waterproof materials, or food packaging contact. We offer guidance on correct sampling procedures.
4. How long does it take to get PFAS testing results?
Our average turnaround time is 10 business days. Expedited testing (5 days or fewer) is available on request.
5. What’s the difference between EPA Method 537.1 and Method 533?
EPA 537.1 focuses on long-chain PFAS compounds, while 533 targets short-chain PFAS. ResolveMass offers both methods, allowing for comprehensive analysis.
6. Are PFAS regulated in Canada?
Yes. Health Canada has issued drinking water quality guidelines for total PFAS levels. Provinces like Ontario and BC are also implementing their own regulations. Learn more on our PFAS regulations insight page.
7. Can PFAS be tested in soil and air?
Yes. We provide PFAS analysis for:
- Soil and sediment
- Groundwater and surface water
- Stack emissions and ambient air (via TO-13A and TO-17 methods)
8. How does ResolveMass ensure data quality and reliability?
Every PFAS testing result undergoes:
- Internal QA/QC checks
- Certified reference standards
- Blanks, spikes, and duplicates
- Chain-of-custody documentation
Our lab is ISO/IEC 17025 accredited, ensuring scientific integrity.
9. What is the cost of PFAS testing?
Testing prices vary based on sample type and turnaround time. Typical costs range between $200–$600 per sample. Request a custom quote on our contact page.

Real-Time Case Study: PFAS in Groundwater Near Industrial Landfill
Project Overview:
A municipality in Ontario engaged ResolveMass to assess PFAS levels near a decommissioned industrial landfill.
Sample Volume & Method:
- 12 groundwater wells tested
- EPA Method 533 and 537.1
- Sampling at 3 depths per well
- Detection limit: 1.8 ppt for PFOS
Key Results:
- 8 out of 12 wells exceeded the Canadian drinking water limit (70 ppt combined PFAS)
- PFOS detected at 145 ppt in a deep-well sample
- Leachate found to be the primary source
Impact:
- Immediate notification to Ministry of Environment
- Remediation plan initiated
- Local advisory on well water issued
This project illustrates our practical expertise in detecting, analyzing, and interpreting PFAS data. Scientists across Canada rely on our data to inform real-world decisions.
10 Scientifically Informed FAQs on PFAS Testing
1. How stable are PFAS samples during transport?
PFAS are chemically stable, but sample preservation is critical. Refrigeration at 4°C is mandatory. Field blanks and cooler blanks are used to ensure no cross-contamination.
2. What are emerging PFAS compounds?
New-generation PFAS like HFPO-DA (GenX) and ADONA are being tested due to regulatory changes. ResolveMass regularly updates compound libraries to stay compliant.
3. Can PFAS be detected in food packaging?
Yes. We test paper and plastic packaging via methanol extraction and LC-MS/MS, crucial for food safety compliance.
4. What is Total Oxidizable Precursor (TOP) assay?
TOP assay identifies PFAS precursors that convert into terminal PFAS in the environment. We offer this for full exposure assessment.
5. Are fire training grounds high-risk PFAS zones?
Yes. Firefighting foam residues contain AFFF-based PFAS. We’ve done high-resolution mapping for many such locations across Canada.
6. How does PFAS affect biological systems?
PFAS disrupt liver enzymes, immune response, and are linked to reproductive toxicity. Testing is often required in ecotoxicological studies.
7. Are PFAS tests admissible in court?
Absolutely. Our reports include chain-of-custody logs, accredited methods, and legally defensible QC documentation.
8. What matrix interferences affect PFAS detection?
High organic content in soil or water can affect results. We use matrix-matched calibration to minimize interference.
9. Can PFAS testing be combined with other analytes?
Yes, but only with non-interfering methods. We advise separate extraction for VOCs or metals to maintain PFAS integrity.
10. How often should PFAS be monitored?
Quarterly testing is recommended for high-risk areas. Annual testing is acceptable for baseline risk assessments.
