ASTM Meetings are attended by a diverse group of industry representatives, including manufacturers, users, distributors, testing laboratories, academicians, consultants and government personnel. ASTM staff members are also present at meetings to provide any needed support or guidance related to ASTM policy. There is no charge to attend ASTM International standards development meetings, and all are welcome. All ASTM meeting attendees have a voice and are encouraged to participate in meeting discussions.
PFAS Concentrations in Water Supplies
ASTM International’s water committee (D19) has approved a new standard that will help address global concerns about the concentration of polyfluoroalkyl substances (PFAS) in water supplies. According to ASTM International member William Lipps, the new standard required testing of nine complex wastewater matrices, each spiked in triplicate at three concentrations spanning the analytical range of the method. “Very good precision and recovery obtained on all matrices, along with precision and recovery obtained on spiked reagent water, were used to calculate the quality control limits included in the method,” says Lipps. “These limits establish criteria that individual laboratories must meet before running samples and criteria that will be used to demonstrate performance of labs when running samples.” Lipps notes the new standard will help to minimize water use in laboratories and help keep water clean by providing new methods for the analysis of trace contaminants in water. “The smaller volumes required for this test are 25-100 times less volume than a typical EPA method, reducing shipping weight and cooler size, resulting in a smaller carbon footprint,” says Lipps. “The minimal extraction, while using plastics, minimizes their use compared to other PFAS

methods; in this method, the sample is extracted in the same vial in which it was sampled.”
Lipps says that all interested parties are invited to join in the interlaboratory study now being planned for the new standard, which will soon be published as D8421.
Earlier this year, ASTM International also announced they are providing no-cost public access to a suite of more than two dozen standards used in the production and testing of personal protective equipment to combat the coronavirus public health emergency. For more information, visit

A new ASTM International standard will help laboratories to better determine the presence of polyfluoroalkyl substances (PFAS) in environmental samples. ASTM’s committee on environmental assessment, risk management and corrective action (E50) developed the new standard. PFAS are a large, complex group of compounds found in water, air, fish, and soil throughout the world. Additionally, some consumer, commercial, and industrial products contain PFAS. These widely used chemicals persist, breaking down slowly. The ongoing, expanding nature of PFAS environmental awareness and the need for more comprehensive investigations have caused increased demand for PFAS environmental sampling and analysis. “The new guide will assist users in navigating environmental sample analytical test methods for both targeted and non-targeted analytical approaches, as well as additional protocols applicable to PFAS,” says ASTM International member Eileen Snyder. According to Snyder, the new standard (E3302) will assist a wide range of users, including testing laboratories, remediation professionals, data reviewers, state and federal regulators, tribes, international organizations, water treatment systems, industrial dischargers, and more. Snyder, regional technical coordinator, Alpha Analytical, says that all interested parties are invited to join in the standard development activities of E50. The committee is working on proposed standards for PFAS data evaluation and sample collection, as well as on PFAS-related topics such as site screening and initial site characterization.
