1. Introduction

Per- and Polyfluoroalkyl Substances (PFAS) have emerged as a significant environmental and public health concern due to their persistence in the environment and potential adverse health effects. The EPA's new National Primary Drinking Water Regulation for PFAS represents a pivotal shift in addressing this challenge, setting legally enforceable limits for several PFAS chemicals in drinking water.

This white paper will..

Provide a detailed analysis of the new regulation
Explore its implications for various professional fields
Offer strategies for compliance and adaptation
Discuss available resources and funding opportunities
Examine potential challenges and opportunities arising from this regulatory change

2. Overview of the New PFAS NPDWR

The EPA has established Maximum Contaminant Levels (MCLs) and Maximum Contaminant Level Goals (MCLGs) for several PFAS compounds:

Chemical    MCLG    MCL
PFOA    0    4.0 ppt
PFOS    0    4.0 ppt
PFNA    10 ppt    10 ppt
PFHxS    10 ppt    10 ppt
HFPO-DA (GenX chemicals)    10 ppt    10 ppt
Additionally, the EPA has introduced a Hazard Index approach for mixtures of PFNA, PFHxS, HFPO-DA, and PFBS, with a Hazard Index limit of 1.

Key aspects of the regulation:

Approximately 100 million Americans served by public drinking water systems will see reduced PFAS exposure.
Public water systems have three years to complete initial monitoring for these chemicals.
Systems detecting PFAS above the new standards have five years to implement solutions.
Water systems must notify the public if levels of regulated PFAS exceed the new standards.

3. Implications for Professional Fields

The new PFAS NPDWR has far-reaching implications across various professional fields. Here, we examine the key considerations and recommendations for each sector:

3.1 Water Utility Managers and Operators

Key Considerations:

Compliance with new monitoring and reporting requirements
Implementation of PFAS removal technologies
Public communication strategies

Recommendations:

Begin planning for PFAS monitoring immediately
Assess current treatment systems for PFAS removal capabilities
Explore funding options through EPA programs for necessary upgrades
Develop clear communication strategies for informing the public about PFAS levels and mitigation efforts
For guidance on PFAS treatment technologies, visit: EPA's Drinking Water Treatability Database

3.2 Environmental Engineers and Consultants

Key Considerations:

Familiarity with PFAS removal technologies
Understanding of the Hazard Index approach for PFAS mixtures
Site assessment and remediation planning

Recommendations:

Stay updated on emerging PFAS treatment technologies
Develop expertise in designing and implementing PFAS removal systems
Offer services for PFAS site assessments and remediation planning
Collaborate with water utilities on compliance strategies

3.3 Public Health Officials

Key Considerations:

Understanding health impacts of PFAS exposure
Communicating PFAS risks to the public
Monitoring local health outcomes related to PFAS exposure

Recommendations:

Develop educational materials on PFAS health risks and exposure reduction
Collaborate with water utilities on public notifications and risk communication
Monitor local PFAS levels and health outcomes to identify potential correlations
Provide guidance on interpreting PFAS test results for individuals and communities

3.4 Legal Professionals

Key Considerations:

Enforcement of new MCLs
Potential litigation related to PFAS contamination
Regulatory compliance advice for clients

Recommendations:

Familiarize with the new PFAS regulations and their legal implications
Advise clients on compliance strategies and potential liabilities
Monitor developments in PFAS-related case law
Stay informed about state-specific PFAS regulations and how they interact with federal standards

3.5 Laboratory Managers and Analytical Chemists

Key Considerations:

Capability to detect PFAS at parts per trillion (ppt) levels
Analysis of multiple PFAS compounds
Quality assurance and control for PFAS testing

Recommendations:

Invest in advanced analytical equipment capable of low-level PFAS detection
Develop and validate methods for analyzing the regulated PFAS compounds
Participate in proficiency testing programs for PFAS analysis
Stay updated on EPA-approved methods for PFAS analysis
For information on EPA methods for PFAS analysis, visit: EPA's PFAS Analytical Methods Development and Sampling Research

3.6 Municipal and State Government Officials

Key Considerations:

Ensuring local water systems comply with new regulations
Managing public concerns about PFAS
Coordinating with state and federal agencies on PFAS issues

Recommendations:

Assess the impact of new regulations on local water systems
Explore federal funding opportunities for PFAS mitigation
Develop local policies and programs to address PFAS contamination
Establish clear communication channels with water utilities, health departments, and the public

4. Funding and Resources

The Biden-Harris Administration has dedicated significant funding to address PFAS contamination:

$9 billion through the Bipartisan Infrastructure Law for communities impacted by PFAS pollution in drinking water
Additional $12 billion in Bipartisan Infrastructure Law funding available for general drinking water improvements, including addressing PFAS
Nearly $1 billion announced for states and territories through the Emerging Contaminants in Small or Disadvantaged Communities Grant Program
Other funding sources include:

Water Infrastructure Finance and Innovation Act (WIFIA) program
State Revolving Funds (SRFs)
For more information on funding opportunities, visit: EPA's Water Infrastructure Funding

5. Implementation Timeline

Key deadlines for compliance with the new PFAS NPDWR:

Public water systems have 3 years to complete initial PFAS monitoring
Systems detecting PFAS above new standards have 5 years to implement solutions
Annual Water Quality reports must include PFAS results
Water systems and related professionals should begin preparing for these deadlines immediately to ensure timely compliance.

6. Adaptability to Regulatory Changes

To ensure ongoing compliance and effectiveness in addressing PFAS contamination, professionals should:

Establish a regular review process of EPA updates and scientific literature on PFAS
Create a system for quickly disseminating regulatory changes to relevant stakeholders
Develop potential future scenarios based on emerging PFAS research and policy trends
Foster interdisciplinary collaboration to address complex PFAS challenges
Implement continuous education programs to keep professionals updated on PFAS developments

Challenges:

Technical difficulties in achieving low PFAS detection limits
High costs associated with PFAS removal technologies
Public concern and potential mistrust regarding
