Expert Insights On PFAS Treatment

41. PFAS Contamination At Airports Is A Rising Concern 6/24/2022

    When aqueous film-forming foam, or AFFF, was introduced 50 years ago, its effectiveness at firefighting made it popular with emergency personnel at airports and military bases. Chemical compounds called perfluorooctane sulfonic acid (PFOS) and perfluorooctanoic acid (PFOA) found in AFFF repelled both oil and water and smothered the flames quickly. AFFF created a foam blanket that put out fires and provided additional protection by suppressing fuel vapors and preventing reignition. Its use quickly spread, not just to put out fires but in equipment testing, training exercises, and during fuel spills as a preventative measure.

42. Taking The "Forever" Out Of PFAS: The Future Of PFAS Remediation 5/5/2022

    As PFAS treatment technologies continue to emerge, CDM Smith reviews some considerations for the existing options — and introduces a new one.

43. Multidistrict Litigation Suit For PFAS Contamination Gains Momentum 4/13/2022

    Water system providers across the U.S. have joined a multidistrict litigation (MDL) suit claiming that their water supplies are contaminated with per- and poly-fluoroalkyl substances (PFAS) from aqueous film-forming foam (AFFF). These chemicals have been used for decades to extinguish chemical or petroleum fires at military bases, airports, and industrial facilities. 

44. New Hampshire Puts $350 Million To Work From A Successful Lawsuit Over MTBE Contamination 1/25/2022

    From cleaner water to infrastructure upgrades, good stories are easy to find after the state of New Hampshire set out to hold polluters accountable for contaminating groundwater with methyl tertiary-butyl ether (MTBE), a gasoline additive now banned or limited in several states. Through private well testing, watershed protection and new water facilities, the people of the Granite State are turning the tide on water contamination and restoring the safety and reliability of their drinking water supplies thanks to bold action to make sure polluters pay for damage.

45. How To Truly Eradicate PFAS From Our Drinking Water 1/12/2022

    As so-called “forever chemicals” get more attention from regulators and the public at large, the pressure is on to eliminate these pervasive contaminants — forever.

46. State AG Enforcement As EPA Finds PFAS More Toxic Than Previously Thought 11/29/2021

    According to a new study conducted by the U.S. EPA, “forever chemicals” are far more harmful than previously believed.

47. Addressing Challenges Of PFAS: Protecting Groundwater And Treating Contaminated Sources 9/27/2021

    Groundwater is a vital resource across the United States and throughout the world. Over 50 percent of people in the United States depend on groundwater for safe drinking water. Groundwater is also one of our most important sources of water for irrigation and food production.

48. Impact Of Congressional Ruling On PFAS 8/16/2021

    The ability of per- and polyfluoroalkyl substances (PFAS) to contaminate everything in their wake and resist degradation in nature has propelled these “forever chemicals” into a serious public health concern over the past two decades, galvanizing calls for sweeping federal legislation.

49. Implementing Granular Activated Carbon Systems: Important Design And Start-Up Considerations 7/6/2021

    As granular activated carbon (GAC) is increasingly employed to treat PFAS, new practitioners can improve their results by knowing what to expect — thanks to data and experience acquired from prior installations.

50. PFAS In Our Water Supply: Treatment vs. Destruction 5/3/2021

    As per- and polyfluoroalkyl substances (PFAS) demand increasing attention due to health, environmental, and regulatory concerns, the pros and cons of available treatment options should be thoroughly evaluated.
