The EPA just announced final PFAS Drinking Water MCLs (maximum contaminant levels).

EPA released an updated Interim Guidance on Destroying and Disposing of Certain PFAS and PFAS-Containing Materials. The guidance contains a new technology evaluation framework that enables technology developers to assess emerging innovative destruction and disposal methods.

The final version of EPA 1633 was released by the U.S. EPA on January 31, 2024. EPA encourages laboratories, regulatory authorities, and other interested parties to review and use these methods, and EPA recommends their use now in NPDES permits. Eurofins has thoroughly reviewed the final version of method 1633 and determined what is needed for implementation across our network of PFAS laboratories.

There are two sides to RCRA, the regulation of hazardous waste that you probably know as the cradle to grave law. Under Subtitle C of this law, EPA has the authority to control and regulate hazardous waste from the cradle to the grave, requiring tracking of hazardous waste from generation to disposal.

Scientists are urging further testing of a hazardous toxin affecting residents in Rome, Georgia, following an Atlanta News First investigation that uncovered elevated levels of perfluoroalkyl (PFAS) compounds in some residents' blood.

Draft 4 of EPA Method 1633 has been published with the note that this method is now finalized for the aqueous matrices.

The American Chemical Society’s Environmental Science and Technology journal recently published a study, “A Self-Collection Blood Test for PFASs: Comparing Volumetric Micro-Samplers with a Traditional Serum Approach” which reports a test developed by Eurofins Environment Testing is a viable self-collection tool for assessing human exposure to PFAS.

A simple equilibrium passive sampler, consisting of water in an inert container capped with a rate-limiting barrier, for the monitoring of per- and polyfluoroalkyl substances (PFAS) in sediment pore water and surface water was developed and tested through a series of laboratory and field experiments.

In this community-led pilot study we sought to investigate the utility of expanded per- and polyfluoroalkyl substances (PFAS) testing for drinking water, using a targeted analysis for 70 PFAS and the Total Oxidizable Precursor (TOP) Assay which can indicate the presence of precursor PFAS.

In December 2022, the 3rd Draft of EPA Method 1633 was released which includes quality control criteria that was produced from a multi-laboratory validation study conducted for wastewater.
