The New Jersey Department of Environmental Protection posted interim soil remediation standards for several per- and polyfluoroalkyl substances (collectively PFAS) to include perfluoro nonanoic acid (PFNA), perfluorooctanoic acid (PFOA), perfluoro octane sulfonate (PFOS), and hexafluoropropylene oxide dimer acid and its ammonium salt (GenX). Posted in the October 17 NJ Register, the interim standards pertain to the direct contact and migration to groundwater exposure paths, and apply immediately.
Given there are thousands of PFAS compounds, additional interim and final standards for various exposure routes are anticipated for various media — soil, groundwater, surface water, and sediment.
