You may never have heard of PFAS, but they are a class of toxic chemicals that are everywhere.

These manmade chemicals have traveled through the environment into the far reaches of the world, and they don’t break down and go away, which is why they are called “forever” chemicals.

PFAS are a crisis in California. Virtually all of us have one or more PFAS in our bodies. While we do not make the chemicals in this state, limited testing to date has already detected 9 PFAS in the drinking water supplies of 16 million in California.  This can be attributed to the manufacture and use of a wide array of products containing PFAS, including personal care and cleaning products, textiles, firefighting foams, industrial lubricants, and even pet medications.

Because of the threat posed by PFAS, Clean Water Action launched a campaign in 2018 to achieve two things:

  1. Stop the use of PFAS at the source to avoid further environmental contamination and human exposure
  2. Address the chemicals that are already in our water, air, and soil

What Are PFAS?

The acronym PFAS stands for perfluoroalkyl and polyfluoroalkyl substances, a class of between 12,000 and 14,000 human-made chemicals that are made by combining fluorine and carbon in one of the strongest chemical bonds on Earth.  This makes them very useful in a wide variety of products. Many places in California can be impacted by manufacturing-related PFAS contamination because PFAS are or have been used in electroplating, firefighting foams, and other industrial processes. In terms of consumer products, PFAS are generally found in non-stick, water, stain and grease-resistant items.  

While we do not know the true extent of PFAS use in consumer products, common applications include food packaging, textiles, cosmetics, dental floss, cookware, outdoor gear, medications and medical devices, paint and building materials, car and floor waxes, and other cleaning products.

Unfortunately PFAS persist in the environment and have been linked to serious health impacts. The use of older forms of PFAS, called PFOA and PFOS have been phased out in the US due to an increased awareness of their harmful effects. Yet newer versions which are replacing them in consumer products which are equally as persistent in the environment, more difficult to remove from water, and are also toxic.

PFAS Conference Logo

On February 4, 2022 Clean Water Action co-hosted an innovative conference on PFAS in San Francisco Bay Fish with the San Francisco Estuary Institute and the California Indian Environmental Alliance.  The conference brought together 250 people representing at risk fishing communities, regulators, scientists, waste water professionals, and other interested stakeholders to discuss what we know about PFAS in the Bay (some of the highest levels in wildlife in the world!) and the human and environmental justice implications, as well to explore next steps.

Why Are They Harmful?

PFAS are bio-accumulative, meaning that they gradually build up in humans, as well as the environment over time. In fact, they can be found in 97% of human blood samples.

PFAS have been linked to several serious health issues, including:

•    kidney and testicular cancer
•    liver malfunction
•    thyroid diseases
•    delayed puberty
•    early menopause in women
•    reduced immune system responses in children
•    birth defects in newborns
•    elevated cholesterol for both producers and consumers of goods containing PFAS 

According to the US Agency for Toxic Substances and Disease Registry, primary exposure routes are from drinking contaminated drinking water or eating fish caught in PFAS polluted water, eating food contaminated from packaging, ingesting dust, and using certain consumer products. 

Environmental Concerns

PFAS chemicals not only bioaccumulate in our bodies, they are impacting soil, water, and even wildlife across the planet. While there are numerous ways PFAS get into the environment, industrial spills and the use and ultimate disposal of PFAS-containing products are major causes. Consequently, removing PFAS from these products not only protects consumers but prevents environmental harm as well.  

California In The Lead

Given the number of PFAS in commercial use, the current scope of the problem in the state, and the variety of contamination sources, California needs a comprehensive strategy that 1) reduces the use of PFAS chemicals in products and industrial processes and 2) develops the technology to address the chemicals already in our environment. Fortunately, as an innovator state, we are in a unique position to take this on.  That is why Clean Water Action has launched a PFAS campaign aimed at educating decision makers and the public about the impacts of these chemicals and calling for action on products, water monitoring and treatment, and the leaching of PFAS into our air, soil, or water.

What We Have Accomplished So Far:

Since the launch of our campaign, Clean Water Action has co-sponsored or actively advocated for several successful state initiatives to eliminate significant uses of PFAS in products.  These include:

SB 1044 (2020) Banned the use of PFAS containing firefighting foams for non-federally required uses by 2022.  Firefighting foam is a major source of PFAS in water.  See for details.

AB 1200 (2021) Banned PFAS in fiber or paper-based food packaging by January 1, 2023.

AB 652 (2021) Banned PFAS in specified products designed for use by infants and children under 12 years of age by July 2023.

State regulation on PFAS in carpets, rugs, and after-market fabric sprays (2021 and 2022) Requires all manufacturers selling such products in California to report the presence of PFAS to state regulators and then remove the PFAS, stop selling the products in this state, or provide the state with a plan to find a safer alternative to the chemicals.  This action has been supported by the decision by major retailers to stop selling carpets or rugs containing PFAS.

AB 1817 (2022) Banned PFAS in clothing and household textiles by January 2025 (with a short extension for outdoor gear meant for extreme conditions).  

What can you do?

The first thing you can do is to educate yourself about the issue. To learn about water pollution in the state, as well as the various products PFAS are commonly used in and what Clean Water Action is doing about them, please click on the sections below.
