NJDEP Formally Adopts PFAS Site Remediation Standards: Numerical Cleanup Levels for PFOA, PFOS, PFNA, and GenX
On June 15, 2026, the landscape of New Jersey real estate development and environmental compliance shifted fundamentally. The New Jersey Department of Environmental Protection (NJDEP) formally adopted final enforceable site remediation standards for four prominent per- and polyfluoroalkyl substances (PFAS): PFNA, PFOA, PFOS, and GenX (HFPO-DA). What was previously a murky world of interim criteria […]

NYSDEC Part 375 Soil Cleanup Objectives: Where PFAS Rulemaking Stands in 2026
For over five years, New York’s remediation community has been operating in a state of "regulatory limbo" regarding Per- and Polyfluoroalkyl Substances (PFAS). We’ve navigated a thicket of interim guidance documents, draft policies, and sampling protocols, all while waiting for the New York State Department of Environmental Conservation (NYSDEC) to codify formal Soil Cleanup Objectives […]
NJDEP Finalizes PFAS Remediation Standards: What LSRPs and Site Owners Need to Know
On June 15, 2026, the New Jersey Department of Environmental Protection (NJDEP) officially adopted final, enforceable remediation standards for per- and polyfluoroalkyl substances (PFAS) under N.J.A.C. 7:26D, alongside critical amendments to N.J.A.C. 7:9C (Ground Water Quality Standards) and N.J.A.C. 7:26E (Technical Requirements for Site Remediation). For years, Licensed Site Remediation Professionals (LSRPs), property owners, and […]
NYSDEC Proposes Landmark Landfill Leachate PFAS Pretreatment Rules (Part 360/363)
On July 1, 2026, the New York State Department of Environmental Conservation (NYSDEC) published a sweeping Notice of Proposed Rulemaking in the State Register that fundamentally alters how solid waste management facilities handle leachate. Targeting 6 NYCRR Parts 360 and 363, the proposed amendments establish first-in-nation pretreatment standards specifically designed to eliminate per- and polyfluoroalkyl […]
NYSDEC Proposes Landmark Landfill Leachate Treatment Rules: PFAS and 1,4-Dioxane in the Crosshairs
On July 1, 2026, the New York State Department of Environmental Conservation (NYSDEC) signaled a seismic shift in waste management policy. The department officially proposed landmark amendments to 6 NYCRR Parts 360 and 363, targeting the systematic treatment of emerging contaminants in landfill leachate. For active Municipal Solid Waste (MSW) and Construction and Demolition (C&D) […]
Managing PFAS in Recycled Biosolids: NYSDEC’s 2026 Regulatory Overhaul
As of August 2026, New York’s PFAS framework for biosolids is no longer limited to wastewater treatment plant residuals. NYSDEC now requires a broader data and management approach covering biosolids sources, commercial biosolids-derived products, land application, and: through separate proposed rules: landfill leachate. The practical message for municipalities, wastewater utilities, agricultural operators, product manufacturers, and […]
NJDEP’s Expanded 2026 PFAS Remediation Standards: What Developers and LSRPs Must Know
On June 15, 2026, the New Jersey Department of Environmental Protection (NJDEP) adopted amendments to N.J.A.C. 7:9C, 7:26D, and 7:26E. The rule converts interim remediation criteria for GenX, PFNA, PFOS, PFOA, and methanol into enforceable requirements and expands required analytical coverage when site contaminants are unknown or […]
PFAS Soil Leachate Standards: The New Compliance Floor for NJ Remediation
If you’ve been tracking environmental regulations in New Jersey, you know the "interim" grace period for PFAS is officially over. As of June 15, 2026, the New Jersey Department of Environmental Protection (NJDEP) has formally adopted numeric soil and soil leachate remediation standards for four major per- and polyfluoroalkyl substances (PFAS). This isn't just another […]
The GenX Standard: NJDEP Finalizes PFAS Remediation Rules (0.02 µg/L Groundwater)

On June 15, 2026, the New Jersey Department of Environmental Protection (NJDEP) finally stepped out of the interim period and into a hard-coded regulatory reality. With the formal adoption of amendments to the Ground Water Quality Standards (N.J.A.C. […]
Phase I ESA 2026 Checklist: Integrating the New NY Environmental Justice and NJ PFAS Standards
If you’re developing in New York or New Jersey right now, the ground just shifted. As of June 2026, the "standard" Phase I Environmental Site Assessment (ESA) you’ve relied on for years is no longer enough to protect your investment or keep your project on schedule. Understanding compliance is only half the battle; for a […]
The New NJDEP Technical Requirements: Why Your AOC Sampling Must Now Include PFAS and Dioxins
If you are developing property in New Jersey, the goalposts just moved. For years, when you encountered an "unknown" Area of Concern (AOC): maybe an old pipe with no records or a patch of stained soil in a corner of the lot: the standard operating procedure was to run a "full suite" of Target Compound […]
