AFFF Contamination — A Precursor To Long-Term Environmental Hazards
Although aqueous film-forming foam (AFFF) has been used to save lives, it may be impairing the health of many more. The persistent and pervasive nature of PFAS is again the culprit.

PFAS Found In Sediment And Surface Water At Milwaukee Estuary Area Of Concern
The Wisconsin Department of Natural Resources has received results from surface water and sediment sampling performed in November 2019 to determine if per- and polyfluoroalkyl substances, commonly called PFAS, are present in areas that are targeted for potential cleanup-related dredging across the US EPA-designated Milwaukee Estuary Area of Concern (AOC).

White House Steps In To Weaken EPA PFAS Regulation
The White House has reportedly taken steps to diminish a rule proposed by the U.S. EPA to curb the presence of per- and polyfluoroalkyl substances (PFAS), one of the country’s most prevalent and contentious drinking water contaminants.

PFAS Regulations: What You Need To Know
As states and the federal government march toward PFAS regulation, it’s only a matter of time before most municipal water systems will be required to address the contaminant. And with the constantly changing patchwork of proposed regulations, meaning the earliest imposed rules will likely evolve, PFAS promises to be a moving target for a long time. Preparing now is the key to be in the best position to maintain compliance.

Activated Carbon For PFAS Treatment: Why Base Material Matters
Granular activated carbon (GAC) is an effective and proven technology for the removal of PFAS and many other harmful organic compounds. But, not all products are the same and using the right GAC can make the difference between success and failure.

How To Cost-Effectively Remove Multiple Contaminants From Water Simultaneously
Water utilities must protect the public health by producing a final product that meets all regulatory requirements. In addition, the water must be pleasing to the customer, with no taste or odor issues. And finally, utilities must stay abreast of emerging contaminants, health advisories, and new regulations. It’s a constant challenge to shoulder these responsibilities while staying within tight budgets. Utilities need a technology that helps them achieve multiple goals cost-effectively.

Ultrapure Water For Determination of Toxic Elements In Environmental Analyses
In this paper the importance of reagent water quality for toxic element environmental analyses is discussed, and the suitability of fresh ultrapure water produced using MilliporeSigma water purification systems for ICP-OES and ICP-MS trace element analyses in environmental laboratories is demonstrated.

GAC vs IX For PFAS Removal
Protecting the public health and ensuring water is safe to drink is the highest goal of water system managers. Negative health effects are indicated from exposure to per- and polyfluoroalkyl substances (PFAS), such as perfluorooctanoic acid (PFOA) and perfluorooctyl sulfonate (PFOS). Based on lab studies, the U.S. EPA has issued a health advisory for PFOA and PFOS in drinking water of 70 parts per trillion. While health advisories are not enforceable, they offer a margin of safety for consumers.
PFAS MULTIMEDIA
PFOA and PFAS are organic synthetic chemicals used in the manufacturing of many products. Over several decades they have contaminated the environment, specifically our drinking water sources. Watch the full video to learn more about PFAS, and how to treat it.
ABOUT PFAS
Per- and polyfluoroalkyl substances (PFAS) are a group of man-made chemicals that have sometimes been called “forever chemicals” for their persistent nature in the environment, difficulty to remove through treatment, and bioaccumulation in humans and animals. Two types of PFAS — perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA) — have been identified as toxic by the U.S. EPA, while many more of the nearly 5,000 PFAS formulas are either suspected contaminants or have yet to be studied thoroughly. Originally developed for non-stick coatings, stain-repellant fabric treatments, and firefighting foams, PFAS are especially prevalent near former areas of high use — such as manufacturing facilities, airports, military bases, or the sites of large fires — yet widely problematic.
In February 2020, the EPA issued preliminary determinations to regulate PFOA and PFOS under the Safe Drinking Water Act (SDWA) and establish the first national PFAS monitoring and treatment requirements for drinking water utilities (see EPA’s PFAS Action Plan). Numerous U.S. states, however, have already developed rules and guidance for PFAS.
This solution center addresses the topics and questions most important to drinking water professionals as the PFAS issue evolves — How does PFAS get into drinking water? How do utilities monitor for PFAS? What treatment technologies remove PFAS? What are the regulatory limits for PFAS? — with answers provided through breaking news stories, editorial insight, and technical discussions.
