In recent years, PFAS chemicals have become a major concern in both public health and environmental discussions, and for good reason. These contaminants, often called “forever chemicals,” have been discovered in everything from non-stick cookware to firefighting foam, and most critically, in our drinking water supplies. If you live in Southern California, understanding the dangers of PFAS and knowing how to protect your home or business is essential.
At SoCal Water Solutions, we are California’s water experts. With over 50 years of combined experience, our licensed team provides custom water treatment systems, designed to address your unique water quality challenges. When it comes to PFAS and other harmful substances, we bring proven solutions to keep your water safe.
What Is PFAS?
PFAS stands for Per- and Polyfluoroalkyl Substances, a large family of more than 12,000 synthetic chemicals first developed in the 1940s. PFAS have been used in a wide variety of consumer and industrial products because of their resistance to heat, grease, oil, and water. This chemical durability, however, is precisely why they are problematic: PFAS do not easily break down in the environment or in the human body.
Because of their persistence, PFAS are often referred to as “forever chemicals.” Once released into the environment, they can contaminate soil, groundwater, and surface water for decades.
Common products that may contain PFAS include
Non-stick cookware (like Teflon)
Food packaging materials (fast-food wrappers, microwave popcorn bags)
Stain-resistant carpets and upholstery
Water-repellent clothing
Firefighting foam (especially used around airports and military bases)
For a deeper overview, see the Environmental Protection Agency’s PFAS explanation.
Why PFAS in Water Is Dangerous
Over the past decade, scientists have grown increasingly concerned about PFAS exposure through drinking water. Because these chemicals accumulate in the body over time, even low levels of exposure can lead to health risks.
According to the Centers for Disease Control and Prevention, PFAS exposure has been linked to:
Increased risk of certain cancers (kidney and testicular cancer)
Liver damage and impaired liver function
Hormonal and immune system disruption
High cholesterol levels
Lower infant birth weight and developmental issues in children
Reduced vaccine effectiveness in children
Unfortunately, PFAS contamination is not just a problem near industrial zones. The Environmental Working Group has identified thousands of sites across the U.S. where PFAS has been detected, including in multiple counties in Southern California.
How Do PFAS Get Into Drinking Water?
PFAS contamination can occur in several ways:
Industrial discharges: Factories that manufacture or use PFAS release them into waterways.
Firefighting foam runoff: Foam used in training and emergency situations often seeps into groundwater.
Landfill leachate: As PFAS-containing products break down in landfills, chemicals can leach into surrounding soil and water.
Once in the environment, PFAS are extremely difficult to remove and can spread quickly through groundwater sources, eventually making their way into municipal drinking water supplies.
How to Remove PFAS From Drinking Water
The good news is that effective solutions exist. If you are concerned about PFAS in your water, it is important to understand that not all filters are created equal. Basic pitcher filters or fridge filters do not remove PFAS.
Proven Methods to Remove PFAS
Activated Carbon (GAC) FiltersGranular activated carbon can trap and reduce PFAS levels significantly, though filter replacement is crucial to maintain effectiveness.
Reverse Osmosis (RO) SystemsRO systems force water through a semi-permeable membrane, blocking contaminants including PFAS, arsenic, lead, and more.
Ion Exchange ResinsThese resins work by swapping ions in the water with safer alternatives, effectively capturing PFAS and reducing concentrations.
According to the EPA’s guidance on PFAS treatment, these technologies can reduce PFAS by over 90%.

Frequently Asked Questions (FAQ)
What does PFAS stand for?
PFAS stands for Per- and Polyfluoroalkyl Substances, a group of synthetic chemicals known for their persistence in the environment.
What are the health effects of PFAS exposure?
PFAS exposure has been linked to cancer, immune suppression, hormone disruption, and developmental issues. More details are available from the CDC.
Do common water filters remove PFAS?
No. Basic carbon filters in pitchers or refrigerators do not remove PFAS. You need reverse osmosis, activated carbon, or ion exchange systems.
What is the best water filter for PFAS?
The most effective options are reverse osmosis systems and whole house activated carbon filters. Both are offered by SoCal Water Solutions.
Can I test my water for PFAS?
Yes. PFAS testing requires specialized labs. SoCal Water Solutions can guide you on how to get your water tested and interpret the results.
Is bottled water safer than tap water with PFAS?
Not necessarily. Some bottled water brands may also contain PFAS. A home filtration system ensures long-term safety and reduces plastic waste.
