PFAS articles
On April 10, 2024, the US Environmental Protection Agency (USEPA) finalized the National Primary Drinking Water Regulation (NPDWR) for six per- and polyfluoroalkyl substances (PFAS), together with their isomers and various salts.1 In this article, we summarize implications for water companies and municipalities. We also look beyond the NPDWR to discuss broader potential implications of the MCLs.

Sampling for 29 per- and polyfluoroalkyl substances (PFAS) under Unregulated Contaminant Monitoring Rule 5 (UCMR5) is being performed in 2023-2025. The US Environmental Protection Agency (USEPA) recently released the first batch of results from approximately 4,600 samples collected from 2,000 public drinking water supplies in January-June 2023.

The US Environmental Protection Agency (USEPA) has issued notice that it plans to submit a data collection request to textile manufacturing facilities to collect information relating to the potential presence of per- and polyfluoroalkyl substances (PFAS) in process wastewater discharges from these facilities. In this article, we provide a summary of the proposed textile mills industry data collection plan.

A new final rule adds PFAS subject to Toxics Release Inventory (TRI) reporting to the list of ‘chemicals of special concern’, thus eliminating the de minimis exemption as well as the option to report using the abbreviated Form A. Haley Ahlers looks deeper into the rule and the implications for supplier notification and TRI reporting.

Air emissions, deposition, and subsequent stormwater runoff are emerging as important pathways for PFAS to the environment. However, guidance on addressing PFAS-impacted stormwater is thin on the ground. This article uses a real-world project to demonstrate developing a threshold for PFAS in stormwater and identifying activities to mitigate PFAS concentrations in the facility stormwater.
