Standard Guide for PFAS Analytical Methods Selection
SIGNIFICANCE AND USE
4.1 This guide provides an overview of analytical methods, techniques, and procedures that may be used in determination of PFAS in environmental media.
4.2 This guide provides considerations relevant to the selection and application of PFAS analytical methods, techniques, and procedures, including the limitations of published analytical methods and the potential benefits and challenges of non-standard analytical approaches.
4.3 This guide presents comparisons of published analytical methods and approaches, including tabular comparison of target analyte lists and method features, to aid users in the selection and application of analytical methods and techniques for project-specific applications.
4.4 This guide describes qualitative techniques available to determine total PFAS, including explanation of terms, discussion of techniques, conceptual overview schematic, and summary comparison table.
4.5 This guide provides current information on research trends in PFAS determination techniques applied to environmental media.
4.6 This guide provides an integrated framework that results in efficient, cost-effective decision-making for timely, appropriate response actions for PFAS-impacted environmental media.
4.7 This guide is not intended to replace or supersede federal, state, local, or international regulatory requirements. Instead, this guide may be used to complement and support such requirements.
4.8 This guide may be used by various parties involved in response actions for PFAS-impacted environmental media, including regulatory agencies, project sponsors, environmental consultants and contractors, site remediation professionals, analytical testing laboratories, data reviewers, data users, academic institutions, research institutes, and other stakeholders.
4.9 The users of this guide should consider assembling a team of experienced professionals with appropriate expertise to scope, plan, and execute PFAS environmental data acquisition activities...
SCOPE
1.1 This guide discusses the selection and application of analytical methods and techniques used to identify and determine per- and polyfluoroalkyl substances (PFAS) in environmental media. This guide provides a flexible, defensible framework applicable to a wide range of environment programs. It is structured to support a tiered approach with analytical methods, procedures, and techniques of increasing complexity as the user proceeds through the evaluation process. This guide addresses key decision criteria and best practices to aid users in achieving project objectives. There are numerous technical decisions that must be made in the selection and application of analytical methods and techniques used during environmental data acquisition programs. It is not the intent of this guide to define appropriate technical decisions, but rather to provide technical support within existing decision frameworks.
1.2 This guide informs practitioners on the considerations relevant to the selection and application of analytical methods and techniques for the quantitative and qualitative determination of per- and polyfluoroalkyl substances (PFAS) in a variety of environmental sample media. This guide encourages user-led collaboration with stakeholders, including analytical laboratories, data evaluation practitioners, and regulators, in the selection and application of analytical methods and techniques used to support project-specific decision criteria and objectives as applied within a particular environmental regulatory program. This guide recognizes the complexity and diversity of environmental programs and project objectives and provides technical support for a range of project applications.
1.3 This guide is intended to complement, not replace, existing regulatory requirements or guidance. ASTM International (ASTM) guides are not regulations; they are consensus-based standards that may be followed as needed.
