PFAS in Wastewater: 2025 Regulations, Treatment Challenges, and Compliance Strategies for New Jersey, Pennsylvania, and New York

What Are PFAS and Why Do They Matter in Wastewater Operations?

PFAS, or per- and polyfluoroalkyl substances, are a group of synthetic chemicals used since the 1940s for their resistance to water, oil, and heat. They are found in industrial coatings, nonstick cookware, stain-resistant fabrics, firefighting foams, and numerous other products.

PFAS are often called “forever chemicals” because they do not degrade naturally in the environment. They accumulate in soil, water, and living organisms. In wastewater systems, PFAS pass through traditional treatment processes and remain in effluent and biosolids.

These compounds have been linked to health risks such as certain cancers, immune system effects, developmental issues, and environmental persistence. For wastewater operators in NJ, PA, and NY, PFAS represent both a regulatory compliance challenge and an operational cost driver.

How Do PFAS Enter Wastewater Systems in the Tri-State Region?

In New Jersey, Pennsylvania, and New York, PFAS contamination in wastewater comes from multiple sources:

  1. Industrial Discharges

    • Chemical manufacturing plants

    • Textile mills producing stain-resistant fabrics

    • Metal plating operations using PFAS-based surfactants

  2. Firefighting Foam Runoff

    • Airport facilities

    • Fire training centers

    • Industrial fire suppression systems

  3. Landfill Leachate

    • PFAS-containing waste in municipal and industrial landfills

    • Leachate sent to treatment plants without PFAS pretreatment

  4. Domestic Wastewater

    • Consumer products containing PFAS washed into the sewer

    • Laundry from clothing treated with PFAS-based coatings

    • Cleaning and personal care products with PFAS

  5. Stormwater Infiltration

    • Runoff from PFAS-impacted sites entering combined sewer systems

What Are the 2025 PFAS Regulations in New Jersey, Pennsylvania, and New York?

New Jersey PFAS Rules (2025)

The New Jersey Department of Environmental Protection (NJDEP) has some of the strictest PFAS regulations in the country.

Pennsylvania PFAS Rules (2025)

The Pennsylvania Department of Environmental Protection (PA DEP) is expanding PFAS oversight.

New York PFAS Rules (2025)

New York’s Department of Environmental Conservation (DEC) and Department of Health (DOH) are coordinating enforcement.

What Operational Challenges Do PFAS Regulations Create?

  1. Testing Costs and Complexity

    • Certified laboratory analysis for PFAS can cost $300–$500 per sample

    • Special handling requirements increase labor needs

  2. Sludge Management Restrictions

    • Land application bans or limits for PFAS-impacted biosolids

    • Higher landfill tipping fees for sludge disposal

  3. Treatment Process Adjustments

    • Additional filtration or adsorption steps

    • Increased chemical usage in some processes

  4. Staff Training Requirements

    • Specialized sampling protocols

    • Understanding new permit conditions

  5. Regulatory Scrutiny

    • Higher frequency of inspections and reporting

What Treatment Technologies Can Remove PFAS from Wastewater?

While no single solution fits every facility, these technologies have proven effective for certain PFAS removal goals:

  1. Granular Activated Carbon (GAC)

    • Widely used for PFAS adsorption

    • Requires periodic media changeouts

  2. Ion Exchange Resins

    • High selectivity for specific PFAS compounds

    • Can complement GAC systems

  3. Reverse Osmosis (RO)

    • Removes broad range of PFAS

    • Generates concentrated brine waste

  4. High-Temperature Incineration

    • Used for PFAS destruction in solids

    • Limited availability and high cost

  5. Emerging Technologies

    • Electrochemical oxidation

    • Plasma-based treatments

    • Novel sorbents

How Much Does PFAS Compliance Cost?

Costs vary by facility size, PFAS levels, and treatment needs. Approximate annual cost ranges for a mid-sized municipal facility in NJ, PA, or NY:

Case Example: PFAS Monitoring at a Mid-Sized NJ Facility

A municipal wastewater treatment plant in central New Jersey, processing 4 MGD, was required to begin quarterly PFAS sampling in January 2025. Initial results showed elevated PFOA and PFOS from industrial sources.

Actions taken:

  • Conducted industrial pretreatment inspections for all permitted users

  • Identified a metal finishing facility as the primary contributor

  • Required installation of on-site ion exchange pretreatment

  • Reduced influent PFAS levels by 60% within two quarters

Step-by-Step Checklist for PFAS Compliance in NJ, PA, and NY

  1. Review your current NJPDES, SPDES, or NPDES permit for PFAS conditions.

  2. Establish baseline PFAS levels in influent, effluent, and biosolids.

  3. Identify potential PFAS sources in your service area.

  4. Engage with industries on source control measures.

  5. Evaluate treatment technologies for feasibility.

  6. Train staff on PFAS sampling and handling.

  7. Budget for testing, treatment, and disposal costs.

  8. Maintain detailed PFAS monitoring records.

  9. Communicate regularly with regulators.

  10. Update your PFAS plan annually.

Why Local Expertise is Critical

Each state has unique permit structures, enforcement approaches, and disposal rules. A compliance strategy that works in Pennsylvania may fall short in New Jersey or New York. Local experience is essential to avoid costly missteps.

O&M Solutions specializes in wastewater operations and maintenance across the tri-state region. We help facilities navigate PFAS regulations, design effective compliance programs, and manage treatment solutions.

Conclusion

PFAS regulation is reshaping wastewater operations in New Jersey, Pennsylvania, and New York. Facilities that take early, decisive action will be better positioned to meet evolving permit requirements, control costs, and maintain regulatory compliance.
