ECHA announced publication of an updated PFAS restriction proposal package under REACH, reflecting evaluation of 5,600+ comments received during the 2023 consultation and updates to the background document used by RAC/SEAC in forming opinions. Compliance teams should review whether updated sector descriptions, derogation concepts, and alternatives/conditions discussed in the revised background documentation change internal impact assessments, data-gathering needs, and positions for upcoming committee opinion/consultation stages.
EPA published a guidance/fact sheet on requirements and best practices for collecting and analyzing PFAS samples to support compliance with the PFAS National Primary Drinking Water Regulation (NPDWR). The document highlights method-use boundaries under 40 CFR 141.901 (including that EPA Method 537.1 v1.0 is allowed for initial monitoring only) and provides field/lab QA/QC practices intended to prevent PFAS contamination and ensure defensible monitoring data for compliance determinations.
EPA published a technical guidance document, “Requirements and Best Practices for the Collection and Analysis of Samples for the PFAS National Primary Drinking Water Regulation,” to support implementation of the PFAS National Primary Drinking Water Regulation (NPDWR). Compliance teams at public water systems, labs, and state primacy agencies should review sampling and analytical expectations described in the document to align monitoring programs and quality assurance practices with EPA’s recommended approaches.
EPA published a technical guidance document for the PFAS National Primary Drinking Water Regulation (NPDWR) describing requirements and best practices for collection and analysis of drinking water samples for regulated PFAS. The document covers approved methods and practical considerations (e.g., sample handling and quality controls) that can affect compliance monitoring results. Drinking water compliance teams and laboratories can use this to align sampling plans and QA/QC procedures with EPA expectations.
EPA published a technical fact sheet providing requirements and best practices for collection and analysis of samples for the PFAS National Primary Drinking Water Regulation (NPDWR). The document provides operational guidance on sampling handling, quality control, and laboratory analysis expectations to support compliance monitoring for regulated PFAS in drinking water.
EPA published implementation support materials for the PFAS National Primary Drinking Water Regulation (NPDWR), including a technical document on requirements and best practices for PFAS drinking water sample collection and analysis. This guidance is relevant for public water systems, laboratories, and state primacy agencies supporting monitoring and compliance activities under the NPDWR, and should be incorporated into sampling plans, chain-of-custody procedures, and laboratory method selection/QA controls.
EPA announced it intends to retain the existing NPDWR maximum contaminant levels (MCLs) for PFOA and PFOS, while pursuing additional rulemaking to extend the compliance timeline (EPA stated intent to move the compliance date to 2031) and to rescind/reconsider determinations for other PFAS components (PFHxS, PFNA, HFPO‑DA (GenX), and the Hazard Index mixture). For compliance teams, this signals potential changes to implementation timelines and potentially revised scope/requirements for PFAS drinking-water compliance; affected entities should monitor forthcoming proposed and final rulemaking steps described by EPA.
EPA announced it will retain the National Primary Drinking Water Regulation (NPDWR) maximum contaminant levels (MCLs) for PFOA and PFOS, but intends to pursue future rulemaking to extend the compliance date to 2031 (described as an extension from 2029). EPA also stated its intent to rescind and reconsider regulatory determinations/regulations for PFHxS, PFNA, HFPO-DA (GenX), and the Hazard Index mixture approach. For compliance teams at drinking water systems and impacted stakeholders, this signals a forthcoming amendment process that could change project schedules, compliance planning, and the scope of regulated PFAS parameters; however, the changes are not yet final and require tracking through the upcoming rulemaking.
EPA announced its intent to pursue SDWA rulemaking to extend the compliance deadline for the PFAS NPDWR MCLs for PFOA and PFOS to 2031 while keeping the existing MCL values. EPA also stated its intent to rescind and reconsider portions of the drinking water rule affecting PFHxS, PFNA, HFPO-DA (GenX), and the Hazard Index mixture approach (including PFBS). Compliance teams for public water systems and impacted upstream industries should monitor the forthcoming proposal/final action and evaluate how a potential compliance-date shift and scope changes would affect monitoring, treatment, and customer communications.
