PFAS Testing: What It Is, Why It Matters, and How to Stay Compliant

PFAS Testing: What It Is, Why It Matters, and How to Stay Compliant

PFAS testing has become essential for companies that manufacture, package, or distribute products that may come into contact with water, food, or consumer goods. As awareness of per- and polyfluoroalkyl substances (PFAS) grows, regulators and consumers are demanding proof that products are safe and compliant.

This guide explains what PFAS testing is, how it works, and how businesses can meet regulatory expectations while protecting brand reputation.


What Are PFAS?

PFAS are a large group of synthetic chemicals used for their resistance to heat, water, and oil. They have been widely used in:

  • Food packaging materials

  • Nonstick coatings

  • Firefighting foams

  • Textiles and surface treatments

  • Industrial manufacturing processes

Because PFAS persist in the environment and the human body, they are often referred to as “forever chemicals.”


Why PFAS Testing Is Important

Regulatory Compliance

Governments worldwide are tightening limits on PFAS levels in water, food-contact materials, and consumer products. Businesses must verify compliance through accredited laboratory testing.

Public Health Protection

PFAS exposure has been linked to various health concerns, increasing scrutiny across industries.

Supply Chain Accountability

Brands are increasingly responsible for verifying that suppliers and materials are PFAS-free or within legal thresholds.

Risk Management

Early PFAS analysis helps prevent recalls, legal liability, and reputational damage.


Industries That Require PFAS Testing

PFAS contamination testing is commonly required in:

  • Food and beverage manufacturing

  • Packaging and paper products

  • Water utilities

  • Cosmetics and personal care

  • Textiles and apparel

  • Environmental remediation

Companies operating in regulated markets should integrate PFAS testing into routine quality control.

Liquid Chromatography–Tandem Mass Spectrometry (LC-MS/MS)

The gold standard for PFAS analysis. This method identifies and quantifies individual PFAS compounds at extremely low concentrations.

Total Organic Fluorine (TOF) Testing

Measures total fluorine content to detect the presence of fluorinated compounds, often used for screening.

Targeted vs. Non-Targeted Analysis

  • Targeted testing measures specific PFAS compounds.

  • Non-targeted testing screens for unknown or emerging PFAS chemicals.

Selecting the right method depends on regulatory requirements and product type.


PFAS Testing in Water and Food Contact Materials

PFAS Water Testing

Water systems must meet strict concentration limits. Routine monitoring helps ensure safe drinking water and environmental compliance.

Packaging and Food Contact Materials

Manufacturers must confirm that packaging materials do not introduce PFAS into food products. Migration testing evaluates whether PFAS transfer from packaging to food.


Regulatory Landscape for PFAS

In the United States, the Environmental Protection Agency has established health advisories and enforceable limits for certain PFAS in drinking water, with additional rules evolving rapidly. Many states and international authorities have adopted stricter standards for consumer products and packaging.

Because PFAS regulations continue to expand, businesses should monitor updates and conduct periodic testing.


How to Choose a PFAS Testing Laboratory

When selecting a PFAS lab testing partner, consider:

Accreditation

Choose laboratories with recognized certifications and validated analytical methods.

Detection Limits

Ensure the lab can detect PFAS at levels required by regulation.

Experience With Your Industry

Industry-specific knowledge improves accuracy and compliance.

Turnaround Time

Fast results help maintain production schedules and regulatory timelines.

Data Reporting Quality

Clear, traceable reports are essential for audits and compliance documentation.


Best Practices for PFAS Compliance

  • Audit raw materials and suppliers

  • Implement routine PFAS analysis

  • Maintain testing documentation

  • Stay updated on regulatory changes

  • Conduct risk assessments for new products

Proactive monitoring reduces compliance risk and supports consumer trust.


The Future of PFAS Testing

PFAS testing is expected to expand across industries as regulations tighten and detection methods improve. Companies that implement robust testing programs now will be better positioned to adapt to future requirements.

PFAS testing is no longer optional for many industries. It is a critical component of product safety, regulatory compliance, and brand protection. By understanding testing methods, regulatory expectations, and best practices, businesses can manage PFAS risk effectively and maintain consumer confidence.
