Perfluorooctanoic Acid

About Perfluorooctanoic Acid Issue

Per – and polyfluoroalkyl substances (PFAS) are a family of human-made compounds that are now recognized as one of the world’s greatest threats to human health and ecosystems. Some of the most commonly found PFAS are Perfluorooctanoic acid (PFOA), Perfluorooctane Sulfonate (PFOS), and perfluorononanoic acid (PFNA). There are hundreds of these compounds in use today; the story below explains the beginnings of these chemical compounds, how some of the long-carbon chain substances have been phased out of use in the U.S., and how the worldwide problem of these “forever chemicals” is being tackled by individuals, communities, organizations, and local and state governments, with the federal government shamefully lagging behind.

A Class-Action Lawsuit

Cover of the book titled Exposure
by Robert Bilott

A class-action lawsuit was brought against Dupont at their West Virginia Washington Works Plant by residents represented by attorney Robert Bilott, exposing willful pollution releases by Dupont of PFC to the environment and a cover up of the issue, setting a fire that eventually led to a sensational expose.  PFOA was found in the drinking water in the region, people in West Virginia and Ohio in the region around the factory were found to have excessive amounts of PFOA in their blood (298 to 369 ppb but some had ppb levels in the thousands); stories of local illness and disease were brought to light. To read the entire story of how Rob Bilott’s litigation changed the world of PFAS, starting with Dupont, read his book “Exposure”, a hair-raising page-turner.

Federal Report

A federal report by an independent scientific review panel, the Science Advisory Board, acknowledged in a report dated May 2006 that the compounds are a “likely” cause of cancer.  EPA-SAB-06-006    SAB Review of EPA’s Draft Risk Assessment of Potential Human Health Effects Associated with PFOA and Its Salts  The Centers for Disease Control and John Hopkins reported health impacts in newborn babies such as low birth weight and reduced head circumference (Benjamin Apelberg, Department of Epidemiology, Bloomberg School of Public Health, John Hopkins University, August 2007). The documentation of damning evidence of serious health effects was building.

A Landmark Paper

A landmark paper by New Jersey scientists was published in 2009. Gloria B. Post*Judith B. LouisKeith R. CooperBetty Jane Boros-Russo§ and R. Lee Lippincott, Division of Science, Research and Technology, New Jersey Department of Environmental Protection, P.O. Box 409, Trenton, New Jersey 08625, Department of Biochemistry and Microbiology, Rutgers University, 76 Lipman Drive, Room 218, New Brunswick, New Jersey 08901, and Bureau of Safe Drinking Water, New Jersey Department of Environmental Protection, P.O. Box 426, Trenton, New Jersey 08625, “Occurrence and Potential Significance of Perfluorooctanoic Acid (PFOA) Detected in New Jersey Public Drinking Water Systems”, http://pubs.acs.org/doi/abs/10.1021/es900301s More studies and reports have been and continue to be published, in the thousands at last count. 

Delaware Riverkeeper Network (DRN) Work

Delaware Riverkeeper Network (DRN) has been working on the problems posed by the presence of perfluorinated compounds in our local environment since 2005 when our staff collected tap water samples from homes in the neighborhoods close to DuPont’s Chambers Works facility in Deepwater, New Jersey on the Delaware River. We suspected that there may be a problem because of news reports about the Bilott lawsuit that had been brought in West Virginia against Dupont for releasing PFOA into the environment. Our sampling revealed the presence of PFOA in the drinking water being used by people in the local community. 

NJDEP Occurrence Study for PFOA in New Jersey

NJDEP published its first Occurrence Study for PFOA in New Jersey public drinking water in 2007 and established a PFOA drinking water guidance level of 0.04 ppb (40 ng/L) based on lifetime health effects. 

DRN Letter Urges to Make Information Public

DRN filed a letter with DEP calling for immediate action to address this and to make the information available to the public. DRN published the data on our website with the documents and notified news media. The data revealed the highest level of any PFAS in raw groundwater in New Jersey to be a long chain PFAS, Perfluorononanoate acid (PFNA or “C9”), in the water well that supplies drinking water to the Borough of Paulsboro, Gloucester County, on the Delaware River. DRN brought this to the attention of NJDEP and the public, notifying Paulsboro and the local community. DRN held several local meetings in the area around Paulsboro and West Deptford to raise awareness and spur action by municipalities.  Several letters to DEP, also available on this website, didn’t move DEP to action in the weeks following the expose of the information. But DRN persisted to loudly rung alarm bells.

EPA Sets a Federal Provisional Health Advisory Level

IN 2009, the EPA set a federal Provisional Health Advisory Level for short-term drinking water exposure to Perfluorooctanoic acid (PFOA) of 0.4ppb and perfluorooctane sulfonate (PFOS) of 0.2ppb, two of the most widely distributed PFAS.

Due to widespread presence in the environment and people’s blood and due to the highly toxic and persistent nature of these compounds, EPA took several actions to stop the use of PFAS in the United States. Of importance was the establishment of the stewardship program to phase out the manufacture and use of long-carbon-chain PFAS and the requirement by EPA that PFAS use must be reported by dischargers and users to the agency. 

EPA Adds PFOA & 5 Other PFAS to the List of Contaminants

In 2012, EPA added PFOA and 5 other PFAS to the list of contaminants to be monitored in a selection of public water systems across the nation. See Third Unregulated Contaminant Monitoring Rule.

Taking Action On Their Own

Meanwhile, in 2013/14 Gloucester County municipalities were taking action on their own as a result of DRN’s expose of the Solvay PFNA contamination; people came out by the hundreds to public meetings demanding the pollution be addressed.  

The Biden Administration

In 2022-2023, the Biden Administration started to take actions that have been long overdue regarding PFAS. Policies and regulations based on up to date science have been pushed by public advocacy and federal legislation but the most directly effective changes are still being made at the state level (as of 2023, 10 states have adopted statewide MCLs, for instance), through litigation (see for example July 2023 $13+M 3M settlement of lawsuits brought by water providers – even though this is only a beginning to the huge costs to clean up all PFAS: https://www.theguardian.com/environment/2023/jun/22/3m-settlement-municipal-water-systems-pfas-contamination), and through advocacy to stop the use of PFAS in consumer products (see Safer States: https://www.saferstates.com/toxic-chemicals/pfas/).

Most Recent

Other regulatory action was taken in January 2022 by NJDEP to address Cl-PFPECA. NJDEP established an interim specific ground water quality criterion for ClPFPECAs of 0.002 µg/L. “The ISGWQC applies to the total concentration of CIPFPECA congeners in ground water and will be the enforceable standard for CIPFPECA, until the specific ground water quality standard for CIPFPECA is established by rule at N.J.A.C. 7:9C.” as explained at https://www.nj.gov/dep/dsr/supportdocs/NewSupportDocuments.html. This essential regulatory standard will be used in remediation and sampling of groundwater contaminated with this compound.
