Arizona Department of Environmental Quality (ADEQ) officials announced today an Environmental Services Agreement (ESA) with the Air Force Civil Engineer Center of $1.7M in U.S. Air Force funding for the Central Tucson PFAS Project (CTPP).
Study: PFAS Present In Almost 42,000 Sites Around U.S.10/21/2021
Federal legislators are still coming to grips with a class of drinking water contaminants that has long been top of mind for treatment operations around the country — one that has just been found at tens of thousands of additional sites throughout the U.S.
Urban Wastes Used As Fertilizers Contain Higher PFAS Than Livestock Manure10/20/2021
Because of their useful surfactant properties, per- and polyfluoroalkyl substances (PFAS) have been massively produced for non-stick coatings, water-repellant fabrics and firefighting foams. However, scientists have detected these highly stable “forever chemicals” throughout the environment, prompting toxicity concerns.
Broad Coalition Of Advocates, Community Leaders, And Officials Praise EPA’s New Roadmap On PFAS10/20/2021
This week, EPA Administrator Michael S. Regan announced the agency’s new strategic Roadmap on PFAS, and it was met with wide praise across government, as well as the environmental and public health community. Here is a snapshot of what they are saying:
EPA Administrator Regan Announces Comprehensive National Strategy To Confront PFAS Pollution10/18/2021
Today U.S. Environmental Protection Agency (EPA) Administrator Michael S. Regan announced the agency’s comprehensive Strategic Roadmap to confront PFAS contamination nationwide.
New Study May Shed Light On Safety Of Biosolids As Crop Fertilizer10/15/2021
Removing PFAS from drinking water has increasingly been a focus for municipal water utilities, but the contaminant’s impact on wastewater is a relatively new area of concern. Most notably, there have been questions about the safety of using biosolids — a byproduct of wastewater treatment that may contain PFAS — as a crop fertilizer.
Best Practices For PFAS Removal In Gravity Filters10/13/2021
PFAS is a growing problem for municipal water utilities. The contaminant continues to show up in more water sources and regulations are a moving target that will likely involve more compounds and lower acceptable limits. As a result, crafting a long-term strategy to address PFAS can be problematic. However, those utilities using conventional gravity filters with anthracite as the filtering media have an opportunity to continue organic removal while adding PFAS removal with a simple conversion.
EWG Study: Almost 42,000 Sources Of Toxic 'Forever Chemicals' Could Be Polluting Surface Or Drinking Water Across The U.S.10/12/2021
A new study by Environmental Working Group scientists finds almost 42,000 potential sources of the toxic “forever chemicals” known as PFAS that could be polluting surface water or drinking water in communities across the U.S.
MSU Receives EPA Grant To Explore Biosolid Treatments And Effects Of Chemical Pollutants9/30/2021
The nearly $2M grant will help the group investigate the impact of current biosolid treatment methods used by wastewater treatment facilities on a variety of pollutants in soil, water and plants.
PFAS HPLC Column8/17/2021
The new Ascentis® Express PFAS HPLC column, with its Fused-Core technology and a particle size of 2.7 μm, delivers fast and high-resolution separations with excellent selectivity, peak shape, and necessary retention to perform in EPA methods 537.1, 533 and 8327.
PFAS Reference Materials8/17/2021
Per- and polyfluoroalkyl substances (PFAS) are man-made chemicals that have been used in industry and consumer products worldwide since the 1950s.
PFAS can be found in:
ALTRA PFAS Solution1/14/2021
Reliable PFAS extraction in water at a fraction of the cost and risk of solutions that rely primarily on adsorption media (activated carbon or ion exchange resins).
Activated Carbon For PFAS Treatment: Why Base Material Matters11/4/2019
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.
Loprest designs and manufactures granular activated carbon (GAC) treatment systems for taste and odor applications, chlorine removal, PFC’s, 1 2 3 TCP, PCE/TCE, 1 4 dioxane, and many other contaminants. Loprest has a long, successful history in the selection and application of the proper carbon media for the application.
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.
