PFAS Forensic Tools: TOP, BLT, Non-Target Analysis (NTA) & TOF, Part 4

Why attend this webinar? As PFAS investigations mature, identifying specific contamination sources becomes critical for liability allocation, remedial strategy, and cost recovery. Advanced forensic tools provide the chemical fingerprinting evidence needed to strengthen your multiple lines of evidence approach.

What you'll learn:

The PFAS Forensics Framework
Effective source identification requires more than standard analytical methods. Discover how to integrate historical records, conceptual site models, chemical forensic tools, and data analytics into a comprehensive investigative strategy.

Expanding Detection Beyond the Standard 40 PFAS
Thousands of PFAS may exist, but conventional methods detect only a fraction. Learn which advanced techniques reveal the "hidden" PFAS that strengthen forensic conclusions and site characterization.

Total Oxidizable Precursor (TOP) Assay
This powerful technique identifies PFAS precursors that convert to persistent PFAS over time. We'll explain how TOP Assay works, how to interpret results, and when oxidation testing provides crucial source discrimination evidence.

Branched vs. Linear Isomer Profiling (BLT)
Isomer ratios create unique chemical signatures indicative of specific manufacturing processes and products. Understand how BLT analysis differentiates between potential sources.

Non-Target Analysis (NTA) and Total Organic Fluorine (TOF)
NTA identifies unknown PFAS compounds without predefined target lists, while Combustion Ion Chromatography quantifies total fluorine content (AOF, EOF, TF). Learn when these techniques add investigative value and their practical limitations.

Making Strategic Decisions
Not every investigation requires advanced forensic tools. We'll provide guidance on when specialized techniques are cost-effective and how to build defensible forensic conclusions.

Who should attend: Environmental consultants, attorneys, corporate environmental managers, regulators, and remediation specialists involved in PFAS liability assessment and source identification.
