Comprehensive PFAS Testing
for Environmental Safety
and Compliance

At Teklab, we offer cutting-edge testing for Per- and Polyfluoroalkyl Substances (PFAS), a group of man-made chemicals that have raised growing concerns due to their persistence in the environment and potential health risks.

Our comprehensive PFAS analysis utilizes state-of-the-art technologies to detect and quantify these harmful substances in water, soil, air, and other environmental samples. With regulatory limits for PFAS continuing to evolve, Teklab’s precise testing ensures your samples meet the latest standards, providing you with reliable data for compliance, risk assessment, and environmental protection.

Whether you’re a municipality, industry, or environmental consultant, our team’s expertise in PFAS testing supports your efforts to safeguard public health and preserve the environment. Our PFAS testing services employ advanced analytical techniques, including High-Performance Liquid Chromatography (HPLC) coupled with Mass Spectrometry (MS), to identify and measure the presence of various PFAS compounds, including the most commonly studied substances like PFOA, PFOS, and their precursors.

✳️With the ability to detect PFAS at ultra-low concentrations, our testing ensures that even trace amounts are accurately quantified, helping you assess potential risks.

Teklab adheres to rigorous quality control standards and utilizes EPA-approved methods, ensuring that your results are both scientifically sound and legally defensible. Additionally, we offer comprehensive reporting, interpreting the findings to help you understand the full scope of contamination, comply with regulatory requirements, and implement effective remediation strategies.

Trust Teklab’s expertise to guide you through the complexities of PFAS testing, from initial screening to detailed analysis and compliance reporting. For years now Teklab has been at the forefront of PFAS analysis by investing heavily into the new instrumentation required from the genesis of researching and implementing testing methodology. Likewise, our new facility will expand our capabilities for testing and enhance the services we offer even further.

What Are PFAS?

PFAS are synthetic organic chemicals composed of carbon and fluorine bonds, which are among the strongest in chemistry. This unique structure gives PFAS their highly desirable properties, including resistance to heat, water, grease, and stains. However, these same properties also make PFAS extremely persistent in the environment, leading to their accumulation in water, soil, air, and living organisms over time.

Key PFAS Compounds:

• PFOA (Perfluorooctanoic acid) and PFOS (Perfluorooctane sulfonate) are the most widely studied and regulated PFAS chemicals.
• Emerging PFAS: Thousands of other PFAS compounds are now being investigated, with new regulations targeting specific compounds.

Why PFAS Testing Matters:

PFAS contamination has been linked to adverse health effects, including:

• Health Risks: Increased cholesterol levels, developmental effects in fetuses, reduced vaccine response in children, liver and kidney damage, and increased risk of certain cancers.
• Environmental Impact: PFAS contamination affects drinking water supplies, ecosystems, and wildlife.

➡️Due to their widespread use and environmental persistence, PFAS testing is crucial for:

• Identifying contamination sources (industrial facilities, landfills, and firefighting sites).
• Protecting drinking water and food supplies.
• Ensuring regulatory compliance with evolving standards, such as the EPA’s National Primary Drinking Water Regulation (NPDWR).

It is our mission to always utilize the latest EPA-approved methods to ensure precise and defensible results. Our investments in state-of-the-art instrumentation and ongoing training reflect our dedication to staying ahead of emerging PFAS detection methodologies.

Teklab specializes in PFAS testing using solid phase extraction (SPE) methodologies 537.1, 533, and 1633.

Please select a sampling guide below to view information regarding best practices for PFAS sample collection.

1. EPA Method 537.1 (View Sampling Guide for 537.1):

• Designed for monitoring PFAS in drinking water.
• Covers 18 PFAS compounds using solid-phase extraction (SPE) and liquid chromatography-tandem mass spectrometry (LC-MS/MS).
• Approved for compliance with the Unregulated Contaminant Monitoring Rule (UCMR 5).

2. EPA Method 533 (View Sampling Guide for 533):

• Specifically designed for drinking water analysis of 25 select PFAS, with a focus on shorter-chain compounds not always captured by EPA Method 537.1.
• This method expands the list of detectable PFAS for a more comprehensive assessment of drinking water quality.
• Offers flexibility in LC column and conditions but mandates specific procedures for sample preservation, quality control, and the SPE extraction process, including the type of SPE cartridge (WAX) and the prohibition of reducing the sorbent mass to aqueous sample volume ratio.

3. EPA Method 1633 (View Sampling Guide for 1633) | (Sampling Guide for 1633 Soil):

• Developed for non-drinking water samples, including wastewater, surface water, and soil.
• Uses SPE and LC-MS/MS to detect a wide range of PFAS compounds.
• Recommended for individual permits and remediation site characterization.

Applications of PFAS Testing

Teklab offers comprehensive PFAS analysis services tailored to a wide range of applications. This includes ensuring the safety of drinking water sources, such as municipal systems and private wells. We support industrial monitoring efforts by identifying potential contamination stemming from manufacturing processes, wastewater treatment facilities, and landfills. Our expertise extends to environmental remediation, providing crucial soil, groundwater, and sediment analysis to guide cleanup strategies. Furthermore, Teklab conducts air quality assessments to detect PFAS in both ambient and indoor environments. Finally, we assist with product safety evaluations by testing commercial goods and food packaging for the presence of PFAS.

Regulatory Updates on PFAS

The EPA has finalized new Maximum Contaminant Levels (MCLs) for PFOS and PFOA in drinking water at 4 parts per trillion (ppt), with additional limits for other PFAS compounds. These regulations are part of a broader effort to mitigate PFAS exposure for an estimated 100 million people in the U.S. The Bipartisan Infrastructure Law has allocated $1 billion to support PFAS testing and remediation projects nationwide.
