PFAS FAQs - Common Questions About PFAS, Testing, and Remediation

PFAS, per- and polyfluoroalkyl substances, are a growing environmental concern that affects communities, businesses, and industries nationwide. As new information and regulations emerge, many people have questions about PFAS contamination, testing, and cleanup methods. To help you better understand these persistent chemicals, Advanced Environmental Services (AES) has compiled answers to some of the most frequently asked questions about PFAS.

Our goal is to help clients across Missouri and the Midwest make informed decisions about protecting their property, water supply, and compliance status through expert PFAS testing, remediation, and treatment services.

What Are PFAS?

PFAS are a group of synthetic chemicals used since the 1940s in manufacturing and consumer products due to their resistance to heat, oil, and water. Common PFAS compounds include PFOA, PFOS, and GenX chemicals. They’re found in products like nonstick cookware, stain-resistant fabrics, food packaging, and firefighting foam (AFFF). Unfortunately, PFAS are extremely persistent and can remain in soil, water, and the human body for decades, which is why they’re often called “forever chemicals”.

How Do PFAS Contaminate Soil and Water?

PFAS enter the environment through industrial discharge, landfill leachate, and the use of firefighting foam. Once released, they migrate easily through soil and groundwater. Over time, this leads to widespread contamination of drinking water sources and agricultural areas. Even trace amounts can pose health and regulatory risks.

What Are the Health Effects of PFAS Exposure?

Studies by the EPA and CDC have linked PFAS exposure to various health effects, including:

  • Increased cholesterol levels
  • Liver and kidney disease
  • Hormonal disruption and immune system suppression
  • Developmental effects in infants and children
  • Elevated cancer risk, particularly kidney and testicular cancers

Because PFAS accumulate in the body over time, long-term exposure, even at low levels, can increase the likelihood of health impacts.

How Can I Tell If My Property Has PFAS Contamination?

The only reliable way to detect PFAS is through professional environmental testing. AES performs PFAS site assessments and laboratory analysis for soil, groundwater, and drinking water using EPA-approved methods. Our testing helps determine contamination levels and the best treatment strategy.

What Are the Most Effective PFAS Treatment Technologies?

PFAS are resistant to traditional treatment methods, so specialized technologies are required. AES utilizes several proven PFAS treatment technologies, including:

  • Granular Activated Carbon (GAC): Removes long-chain PFAS compounds.
  • Ion Exchange (IX): Captures both short- and long-chain PFAS.
  • Reverse Osmosis (RO): Physically separates PFAS from water.
  • Thermal Destruction: Destroys concentrated PFAS waste safely.

Each technology is selected based on the site’s conditions and regulatory requirements.

Read about these methods on our PFAS Treatment Technologies page.

What Regulations Govern PFAS Contamination?

The EPA and many states have enacted strict PFAS regulations to limit exposure and ensure cleanup compliance. The EPA’s 2024 drinking water standards set Maximum Contaminant Levels (MCLs) of 4 parts per trillion (ppt) for PFOA and PFOS. Additional reporting and cleanup obligations apply under federal laws such as the Clean Water Act and CERCLA.
