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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
As technology improves, contaminants can be measured in ever-smaller quantities. Pollutants formerly undetected are now becoming emerging contaminants of concern. Water utility managers must stay abreast of potential new regulations and plan for ways to address these contaminants.
Most industries are required to remove contaminants from wastewater systems before discharge to a receiving stream or municipal facility. Depending on the industry, contaminants may be numerous or difficult to treat. Finding the most effective, cost-efficient treatment method is critical for both business and the environment.
As our ability to measure contaminants at ever smaller concentrations improves, “emerging contaminants” are on the rise. Per the U.S. Environmental Protection Agency (EPA), emerging contaminants are chemicals or materials characterized by a perceived, potential, or real threat to human health or the environment.
When the Cobb County-Marietta Water Authority (CCMWA) anticipated the need to upgrade the Hugh A. Wyckoff water treatment plant, they turned to granular activated carbon (GAC) technology after vetting several alternatives. The plant, a wholesaler in a two-plant system, processes up to 72 million gallons per day and serves about 350,000 people. Comprising of Wyckoff and the James E. Quarles treatment plant, CCMWA is the second largest water provider in Georgia.
Over the past two years, no groundwater issue has perhaps received as much community focus and attention as polyfluoroalkyl and perfluoroalkyl substances like PFOA and PFOS, often referred to as perflourinated compounds (PFCs). The U.S. EPA issued a health advisory, limiting the amount of these compounds to 70 parts/trillion which kicked off a nationwide evaluation of local water sources.
No water contamination issue is grabbing more headlines these days than that of perfluorinated chemicals, commonly referred to as PFCs or PFAS. Concerns over the chemicals have sprung up all over the country, prompted by contamination from industrial wastewater and military firefighting foam. Regardless of where the issue has come up or what caused it, everyone who has been affected wants the same thing: an effective treatment solution. To discuss such a solution, Water Online spoke with Calgon Carbon Corporation.
Behind the terrifying headlines of contaminated water exists an effective, affordable solution. No one wants to be without drinking water, yet many communities around the country are being told their water is unsafe. Watch this video to learn more.
Algae is always present in surface water. However, under the right conditions Harmful Algal Blooms (HABs) can develop. Some HABs, such as cyanobacteria can release toxins such as microcystin that can enter public drinking water systems as well as kill other natural marine life.
Municipal water treatment plants must disinfect the water delivered to homes and businesses.
For more than 60 years, Calgon Carbon has led efforts to make drinking water safer.
As a leading manufacturer of activated carbon, with broad capabilities in ultraviolet light disinfection, Calgon Carbon provides purification solutions for drinking water, wastewater, pollution abatement, and a variety of industrial and commercial manufacturing processes. This animation takes you through the process of manufacturing activated carbon.
Chemical, petrochemical, and oil-reﬁning plants are process-intensive operations with regulatory requirements to protect the surrounding water and air from the effects of industrial pollution. These external demands are matched by equally compelling internal pressures to address product puriﬁcation needs, ﬁnd alternatives to utilizing costly fresh water in production processes, reduce the carbon footprint, and operate efficiently and proﬁtably.
After an activated carbon’s adsorptive capacity has been exhausted, it can be returned to Calgon Carbon for thermal reactivation. With high temperature reactivation followed by off-gas treatment, the adsorbed organic compounds are destroyed and reactivated carbon can be safely and cost-effectively recycled back to facilities for continued use.
PFCS are manmade fully fluorinated compounds which are not naturally found in the environment, are used in a variety of products such as fire fighting foams, coating additives as a surface-activeagent. PFOS (perfluorooctane sulfonate) and PFOA (Perfluorooctanoic acid) are the most commonly produced PFCs, and large amounts of PFCs have been produced during past manufacturing processes and released to the air, soil and water.
The Town of Guilderland and its water treatment plant are located in east-central New York, approximately 7 miles northwest of Albany, and about 125 miles north of New York City. In 2010, officials for the Guilderland Water District authorized a full-scale pilot program to determine the impact on cost and water quality associated with using reactivated carbon as a filtration media instead of virgin granular activated carbon.
