  1. Selecting The Best Solution 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.

  2. How To Prevent GenX Leaching From Filters

    Water professionals must plan and budget to meet new regulations on the horizon. They must find the best technology for removing emerging contaminants, such as perfluorinated compounds. Above all, they want to ensure the health and safety of their customers.

  3. EPA’s Six-Year Review 3: How To Prepare For Potential Rule Revisions

    Staying on top of new regulations is a never-ending responsibility for water professionals. Each new rule may require huge dollars in capital and operating costs. Operators and technicians may need training on new technologies, sampling, and testing methods.

  4. UV Oxidation For Dummies

    As regulatory requirements become more stringent, utilities and businesses look for more effective ways to remove contaminants. Technological improvements in water treatment include various forms of advanced oxidation processes. Calgon Carbon is a global leader in the activated carbon industry with complementary expertise in ultraviolet light (UV) technology. Water Online interviewed Steven Day, Director Product Management/Marketing, to find out more about UV oxidation and how the technology can help to improve water quality.

  5. How To Fight 1,4-Dioxane

    1,4-Dioxane is a contaminant that is known to linger in groundwater and have adverse health effects when consumed. Worse still, it can pose some significant treatment challenges to the operations tasked with eliminating it.

  6. Weighing Carbon For Industrial Wastewater Treatment

    Industrial wastewater operations have to tangle with myriad regulations and countless contaminants every day, making their work some of the most complicated that the treatment sector has to offer. Wrapping one’s head around these challenges can be difficult, but finding the solutions for them can be near impossible. Luckily, there’s an age-old technology that continues to offer industrial wastewater treatment operators salvation.

  7. Remove Perfluorinated Compounds From Drinking Water — Without Creating A Toxic Waste Stream

    Water utility managers have a lot of responsibilities, not the least of which is to keep up with the latest in the industry—contaminants, regulations, technology, and trends. And perfluorinated compounds (PFCs) are on the horizon as contaminants that may affect the public health. Water Online spoke with Calgon Carbon about these important emerging contaminants and how best to remove them.

  8. Granular Activated Carbon Removes PFOA From Drinking Water

    In the fall of 2015, a small village on the border of Vermont in New York State, tested positive for Perfluorinated Compounds (PFCs), specifically Perfluorooctanoic Acid (PFOA), in the municipal drinking water. The influent levels of PFOA in the water were above 600 ng/L, and thus considered harmful to village residents. Realizing that PFOA was on the U.S. EPA Contaminant Candidate List, the Village solicited the services of engineering firm CT Male Associates to investigate treatment options and provide a treatment system.

  10. Granular Activated Carbon Removes 1, 2, 3 – TCP

    What is 1, 2, 3 - TCP? 1, 2, 3 - TCP is a man-made, colorless, chlorinated hydrocarbon that is used as a degreasing and cleaning agent and industrial solvent. It was also used as a chemical in pesticides for low growing crops such as potatoes, tobacco, and beets. 1, 2, 3 - TCP passes through soil and leaches into ground water, contaminating drinking water sources. 1, 2, 3 - TCP is a non-aqueous liquid that is more dense than water, making it difficult to remove from ground water wells. This compound is currently unregulated by the USEPA, although it is on the Contaminant Candidate List 4 (CCL4) for future regulation.
