Understanding PFAs In California’s Water Supply

Understanding PFAs In California’s Water Supply

Understanding Pfas In California’s Water Supply

As concerns grow over emerging contaminants in drinking water, PFAS chemicals have gained national attention—especially in California. These persistent chemicals have been linked to health risks and environmental damage, prompting new regulations and testing requirements across the state. If you rely on well water or oversee a commercial facility, understanding PFAS contamination in California water is critical for ensuring safety and compliance.

What Are PFAS?

Known as per- and polyfluoroalkyl substances, PFAS are a group of man-made compounds found in a wide range of consumer and industrial products. PFAS are often referred to as “forever chemicals” because of their resistance to breaking down in the environment. Once released into the environment, PFAS can accumulate in groundwater and drinking water supplies, making water testing services essential for detection and risk management.

According to the National Institute of Environmental Health Sciences (NIH), people are most likely exposed to PFAS by consuming contaminated water or food, using products made with PFAS, or breathing air containing these substances.

PFOA Vs. PFOS: What’s The Difference?

Two of the most studied and regulated PFAS compounds are PFOA (perfluorooctanoic acid) and PFOS (perfluorooctane sulfonate). While both are part of the larger PFAS chemical group, they differ slightly in chemical structure and common uses. PFOA was widely used in non-stick cookware and water-repellent fabrics, while PFOS was commonly found in firefighting foams and stain-resistant materials.

Both substances are highly persistent in the environment and the human body. Due to their toxicity and environmental longevity, PFOA and PFOS have been phased out in many manufacturing processes, but they continue to pose risks in areas with historical contamination.

PFAS Health Risks & Long-Term Exposure Concerns

One of the reasons PFAS chemicals in water have raised alarm is their bioaccumulative nature—they don’t break down and instead build up in both the environment and the human body over time. How widespread and persistent are these substances in modern life? Reports from the Centers for Disease Control and Prevention (CDC) and the National Health and Nutrition Examination Survey (NHANES) show PFAS compounds present in 97% of human blood samples.

According to the US Agency for Toxic Substances and Disease Registry (ATSDR), long-term exposure to PFAS has been linked to a range of serious health conditions.

  • Kidney & Testicular Cancer
  • Liver Malfunction & Damage
  • Thyroid Disorders & Hormone Disruption
  • Delayed Puberty & Developmental Delays
  • Early Menopause In Women
  • Reduced Immune Response, Particularly In Children
  • Birth Defects & Complications In Newborns
  • Elevated Cholesterol In Individuals

How PFAS Enters California’s Groundwater & Wells

PFAS contamination can occur through industrial discharge, landfill runoff, wastewater treatment plants, and even atmospheric deposition. In California, areas near military bases, airports, and manufacturing facilities are particularly vulnerable. Private wells, which are not subject to the same monitoring as municipal supplies, are especially at risk. Detecting PFAS in water early is key to managing contamination in wells and protecting your property’s water source.

Testing Methods For Detecting PFAS In Water

Testing for PFAS contamination requires advanced analytical techniques capable of identifying trace amounts of these persistent compounds. At M3 Environmental LLC, we use approved laboratory testing protocols to measure PFAS levels with precision and reliability. Our contamination testing methods comply with evolving PFAS regulations in California, helping clients meet both safety and reporting standards.

California’s Evolving Regulations On PFAS

California has taken a proactive stance in addressing PFAS in drinking water, setting notification and response levels for specific PFAS compounds. These evolving PFAS regulations in California are designed to reduce public exposure and ensure water providers take prompt action when contamination is detected. Commercial property owners, schools, and institutions must stay compliant to avoid liabilities and protect public health.

Who Should Consider PFAS Water Testing?

If you own or manage a commercial building, residential complex, school, or healthcare facility—particularly one relying on groundwater sources—you may be at risk for PFAS exposure. Real estate developers, insurance providers, and government agencies are increasingly requiring PFAS water testing before property transactions or redevelopment. A proactive approach to detecting PFAS in water can help you avoid future disruptions and health-related concerns.
