EPA Report on Toxic ‘Forever Chemical’ PFNA Stalled,Sparking Controversy

Washington D.C. – A extensive scientific assessment of perfluorononanoic acid (PFNA), a persistent and possibly dangerous “forever chemical” contaminating water supplies for approximately 26 million Americans, has been held back for months, igniting fears of political maneuvering within the Environmental Protection Agency. The delay raises questions about the agency’s commitment to public health and environmental safety, especially as it considers weakening existing regulations.

What is PFNA and Why is it a Concern?

PFNA, a member of the per- and polyfluoroalkyl substances (PFAS) family, does not naturally degrade in the surroundings, earning it the moniker “forever chemical.” Scientific studies have linked PFNA exposure to a range of health problems, including reduced birth weights and potential damage to the liver and reproductive systems. Recent research indicates possible connections to immune deficiencies and neurological issues.

According to the Environmental Working Group, PFNA contamination has been detected in drinking water across 28 states, originating from sources like firefighting foam and industrial discharge. The chemical has infiltrated not only water sources but also food, air, and even human blood and breast milk.

The Delayed Report and Allegations of Interference

Scientists within the EPA’s Office of Research and Growth completed the PFNA toxicity assessment as early as mid-April. However, the report has remained unpublished, despite being finalized and ready for public release. Sources familiar with the assessment confirm that the delay is unusual, as similar reports have historically been published within weeks of completion.

The timing of the delay coincides with the EPA’s consideration of rescinding stricter drinking water limits on PFNA and other PFAS chemicals established by the Biden

What specific actions has the EPA *not* taken regarding PFNA regulation, despite internal recommendations adn the PFAS Action Plan?

What is PFNA and Why is it a Concern?

perfluorononanoic acid (PFNA), a member of the per- and polyfluoroalkyl substances (PFAS) family, is a synthetic chemical known for its extreme persistence in the environment and the human body. often called “forever chemicals,” PFAS don’t break down naturally,leading to widespread contamination of water,soil,and even human blood.ProPublica’s recent investigative reporting has highlighted the Environmental Protection Agency’s (EPA) slow response to regulating PFNA,despite mounting evidence of its health risks. This delay leaves communities vulnerable to continued exposure.

PFNA was historically used in the manufacturing of non-stick cookware, stain repellents, firefighting foam (AFFF), and various industrial processes. Its unique properties – resistance to heat, water, and oil – made it incredibly valuable, but also incredibly problematic.

The Health Impacts of PFNA Exposure

Exposure to PFNA, even at low levels, has been linked to a range of adverse health effects. Research indicates potential connections to:

* Immune System Suppression: PFNA can weaken the body’s ability to fight off infections.

* Liver Damage: Studies have shown PFNA can cause liver enzyme abnormalities and possibly more severe liver conditions.

* Thyroid Disruption: PFNA can interfere with thyroid hormone production, impacting metabolism and advancement.

* Increased Cholesterol Levels: Exposure is associated with elevated cholesterol, increasing the risk of cardiovascular disease.

* Certain Cancers: Some studies suggest a link between PFNA exposure and kidney and testicular cancer.

* Reproductive and Developmental Effects: PFNA can impact fertility and fetal development.

these health concerns are notably alarming for vulnerable populations,including pregnant women,children,and individuals with pre-existing health conditions.

EPA’s Delayed Response: A Timeline of Inaction

ProPublica’s investigation reveals a concerning pattern of delays from the EPA regarding PFNA regulation. Key points include:

1. 2013: The EPA began internal assessments of PFNA’s toxicity.
2. 2016: Agency scientists recommended establishing a health advisory level for PFNA in drinking water.
3. 2019: The EPA released its PFAS Action Plan, promising to address these “forever chemicals,” but specific action on PFNA remained stalled.
4. 2021-2023: Further internal memos highlighted the risks of PFNA, yet no federal regulation was implemented.
5. 2024: ProPublica publishes its findings, prompting renewed calls for EPA action.

The reasons for this delay are complex, involving political pressure, industry lobbying, and internal disagreements within the agency.Critics argue that the EPA prioritized other PFAS compounds while downplaying the specific dangers of PFNA.

The Role of AFFF and military Installations

A significant source of PFNA contamination stems from the use of aqueous film-forming foam (AFFF) at military bases, airports, and fire training facilities.AFFF is highly effective at extinguishing fuel fires, but it contains high concentrations of PFAS, including PFNA.

* Widespread Contamination: Runoff from these sites has contaminated groundwater and surface water sources, impacting drinking water supplies for nearby communities.

* Military Involvement: The Department of Defense (DoD) is a major user of AFFF and is facing increasing scrutiny for its role in PFAS contamination.

* Ongoing Remediation Efforts: While some remediation efforts are underway, they are frequently enough slow and expensive, and may not fully address the extent of the contamination.

State-Level Action and the Fight for Federal Regulation

In the absence of strong federal regulation,several states have taken action to address PFNA contamination. These measures include:

* Setting Drinking water Standards: States like michigan, New Jersey, and Massachusetts have established their own enforceable drinking water standards for PFNA and other PFAS.

* Implementing Testing Requirements: Many states now require testing of drinking water sources for PFAS contamination.

* Banning PFAS in Certain Products: Some states have banned the use of PFAS in firefighting foam,food packaging,and other consumer products.

Though, a patchwork of state regulations is insufficient to address the national scope of the problem. Advocates are pushing for the EPA to:

* Establish a National drinking Water Standard: A federal standard would provide consistent protection across the country.

* Designate PFNA as a hazardous Substance: This would trigger cleanup requirements under the Superfund law.

* Increase Funding for PFAS Research and Remediation: More resources are needed to understand the full extent of the problem and develop effective solutions.

Protecting Yourself from PFNA Exposure: Practical Tips

While waiting for regulatory action, individuals can take steps to minimize their exposure to PFNA:

* Test Your Drinking Water: If you live near a military base, airport, or industrial facility, consider having your drinking water tested for PFAS.

* Use Water Filters: Activated carbon filters can effectively remove PFAS from drinking water. Look for filters certified to NSF/ANSI Standard P473.

* Avoid Stain-Repellent Products: Choose products that don’t contain PFAS.

* **Be Mindful of Non
