Q&A: Understanding State-Specific Requirements
This Q&A is adapted from the planning and research conducted by our team for episode 2 of our Challenge Accepted podcast about PFAS. The article includes questions from Adam Hackenberg and responses from Brandi Gray (Mid-Atlantic/New Jersey), Beattie McNeal (Gulf Coast/Texas), Christina Rain (California), and Michael Spievack (Florida).
PFAS regulations vary significantly across the country. Why is it important to understand state-specific requirements before developing a strategy?
PFAS are not regulated through a single national playbook, instead requiring compliance with regulations determined state by state. While federal standards continue to evolve, states have developed their own requirements that influence site investigations, reporting obligations, cleanup standards, and closure pathways. What is considered a low-priority site in one location may trigger additional investigation or remediation in another. As a result, site owners must understand current standards and how regulators apply them in practice.
How do cleanup standards and screening criteria differ from state to state?
Each state has established its own framework for evaluating PFAS risk, which creates a complex regulatory landscape for organizations managing potential impacts. Regulatory agencies may apply different screening levels, cleanup criteria, reporting thresholds, and investigation requirements depending on the location, even when evaluating similar site conditions. As a result, the same PFAS detection could lead to a range of regulatory obligations and response strategies, making it essential to understand local requirements before making project decisions.
When does a site investigation become necessary?
The answer depends heavily on the site’s location. In New Jersey, regulators frequently require investigations and closure evaluations even when PFAS impacts are only suspected. Potential source areas, historical uses, and available site data can all trigger further review.
Other states focus more on documented impacts on drinking water or environmental media before requiring extensive investigations. California, for example, may consider proximity to impacted wells, groundwater sensitivity, and environmental justice considerations when determining whether additional evaluation is warranted.
Regardless of location, successful investigations rely on developing a sound conceptual site model and understanding how state-specific screening tools will be applied to collected data.
How important is data evaluation in a PFAS investigation?
Data evaluation is one of the most vital components of a PFAS project, as regulators often scrutinize both the quality and interpretation of the data. Identifying potential background conditions, evaluating potential migration pathways, and distinguishing between on-site and off-site sources can significantly influence the outcome of an investigation. However, acceptance of these approaches varies by state.
What are some state-specific reporting requirements when PFAS is identified?
Reporting obligations can differ dramatically between jurisdictions. In some states, any discharge of a hazardous substance may trigger reporting requirements, creating a lower threshold for notification than many other states.
Elsewhere, reporting requirements are often based on specific concentration thresholds, media impacts, or risk-based criteria. Understanding these obligations before sampling is critical because findings may create immediate regulatory responsibilities.
Another important consideration is identifying alternative sources. Demonstrating that PFAS originated from off-site facilities often requires a combination of forensic analysis, database reviews, historical research, and upgradient sampling. Regulators expect a thorough evaluation of these possibilities before accepting alternative-source arguments.
Bottom Line
PFAS management is not a one-size-fits-all process—regulatory requirements, reporting obligations, cleanup standards, and closure pathways vary significantly from state to state. It’s crucial to engage PFAS experts early in a project to confirm compliance with all applicable regulations. No matter where a project is located, developing a successful PFAS strategy requires understanding the local regulatory framework and tailoring solutions to meet state-specific expectations.
