  • Planning For Total Resiliency In Fighting Contaminants Of Emerging Concern

    In the constant flow of drinking water and wastewater treatment systems, operators have precious little time to skip a beat. When unexpected changes arise — such as being mandated to reduce contaminants of emerging concern (CECs) — the ability to maintain balance throughout the treatment process becomes a driving factor. For decision-makers faced with remaining resilient despite CEC concerns, here are some key points to consider.
  • Fight Contaminants Of Emerging Concern With A Pipeline Of Innovation

    Water treatment challenges are never-ending — from source water availability, to seasonal upsets, to new contaminants of emerging concern (CECs). The best way to stay ahead of such issues is to cultivate a pipeline of innovative solution development ready to address the next challenge. Here are some key insights for evaluating suppliers that are best positioned to do exactly that.
  • Testing Better Paths To Contaminant Control

    As a utility, it is tough enough to be notified that you need to remove a new contaminant of emerging concern (CEC). It’s even harder without having a complete picture of what is involved. For water treatment plants (WTPs) and wastewater treatment plants (WWTPs), here is how choosing the right testing regimen is essential to quantifying the degree of the problem and evaluating the optimum treatment alternatives.
  • Proposed Defense Bill Includes Improved Focus On PFAS Control

    The U.S. House of Representatives’ version of the National Defense Authorization Act (NDAA) for Fiscal Year 2021 (H.R. 6395) includes some positive developments for communities and community water systems impacted by contamination from per- and polyfluorinated substances (PFAS) used at nearby Department of Defense (DoD) installations. Here are some insights on potential benefits for water consumers in those areas.
  • Innovation And Teamwork To Address PFAS Treatment

    When you need to solve a pressing problem, one that is complicated and requires out-of-the-box thinking, you need to focus your attention, minimize distractions and barriers, and work with others to come up with innovative ideas. That’s exactly what EPA’s PFAS Innovative Treatment Team (PITT) is doing to help address PFAS.
  • States Roll Out New PFAS Rules For Water Treatment, Wastewater Monitoring

    As consumers become increasingly concerned about per- and polyfluoroalkyl substance (PFAS) contamination in their source and drinking water, and federal regulators continue to delay implementing stricter limits, states are taking their own actions to curb the problem.
  • ICYMI: EPA, State, And Local Partners Team Up To Address PFAS Across The Country

    Aggressively addressing per- and polyfluoroalkyl substances (PFAS) continues to be an active and ongoing priority for the U.S. Environmental Protection Agency (EPA).
  • States Struggle To Dispose Of 1 Million Gallons Of PFAS Foam

    As states across the U.S. attempt to dispose of major sources of PFAS, delays caused by the pandemic may be increasing the likelihood of exposure.
  • Trump EPA Continues To Aggressively Address PFAS On The Federal, State, And Local Level

    Aggressively addressing per- and polyfluoroalkyl substances (PFAS) continues to be an active and ongoing priority for the U.S. Environmental Protection Agency (EPA).
  • EPA, Federal Family, And The National Academies Collaborate On Public Workshop To Review Federal Research On PFAS

    Today, the U.S. Environmental Protection Agency (EPA) in partnership with the U.S. Department of Defense (DoD), U.S. Department of Agriculture (USDA), and U.S. Department of Health and Human Services (HHS) announced that it has engaged the National Academies of Sciences, Engineering, and Medicine to coordinate a Workshop on Federal Government Human Health Per- and Polyfluoroalkyl Substances (PFAS) Research.

  • 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.
  • Carbon Systems

    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.
  • 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.

How "Forever Chemicals" Polluted America’s Water

North Carolina’s Cape Fear River is a massive water system. It stretches across the lower half of the state, collecting runoff from 29 counties and providing water to millions of people. But in the city of Wilmington, where the river meets the Atlantic Ocean, the water has residents worried.

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.
