  • U.S. Military Bases With Cancer-Linked Contaminated Water Are Undercounted Online

    Per- and polyfluoroalkyl substances (PFAS) are a group of an estimated 5,000 man-made fluorinated chemicals that have been used, since the 1940s, in the manufacturing processes of various consumer products and industries. PFAS are widely used, especially because of their oil and water repellency and temperature and chemical resistance.

  • Mine Waste Dams Threaten The Environment, Even When They Don't Fail

    Scars from large mining operations are permanently etched across the landscapes of the world. The environmental damage and human health hazards that these activities create may be both severe and irreversible.

  • 4 Benefits Of Electrocoagulation For Arsenic Removal From Water

    In water and wastewater treatment, arsenic is classfied as a heavy metal. It is well known for its toxicity and it can cause numerous health problems in humans if consumed at high enough doses. Arsenic can affect the skin, liver, kidneys, bladder, and prostate as well as the nervous, respiratory, cardiovascular, immune, and endocrine systems. Due to the many health risks associated with arsenic, the U.S. EPA has set the drinking water standard at 10 ppb as the maximum allowable concentration in drinking water. Therefore, this is the goal of all treatment systems for arsenic removal from water.

    Plastic has had tremendous impact on society in ways both large and small, such as with microplastics — tiny substances creating a huge problem.

  • Bushfires Threaten Drinking Water Safety. The Consequences Could Last For Decades

    Bushfires pose serious short- and long-term impacts to public drinking water quality. They can damage water supply infrastructure and water catchments, impeding the treatment processes that normally make our water safe to drink. Several areas in New South Wales and Victoria have already been issued with warnings about the quality of their drinking water. Here’s what we know about the short- and long-term risks.

  • Understanding PFAS’ Impact On Remediation Strategies

What are the practical options for community water systems currently confronting this challenge? Here is an overview of several treatments and their relative successes against a wide variety of PFAS compounds.

  • EPA Continues To Update Its Environmental Sampling And Analytical Methods (ESAM) Program

    EPA’s Homeland Security Research Program (HSRP) aims to increase the United States’ capabilities to prepare for and respond to environmental disasters involving chemical, biological, radiological, and nuclear substances (CBRN). As part of this effort, EPA researchers develop scientific data, methods, and tools that can be used by various stakeholders, including laboratories and on-scene coordinators, to increase the effectiveness of response.

  • Nutrient Sensor Action Challenge Winners: Data And Decisions To Manage Excess Nutrients

    Nutrients in the environment from excess nitrogen and phosphorous can result in negative impacts on water quality. EPA is improving nutrient management by incentivizing the development of low-cost technology solutions, such as nutrient sensors, in collaboration with USGS, USDA, NIST, NOAA, and the U.S. Integrated Ocean Observing System (IOOS).

  • WRF Hosts Capitol Hill, State-Of-The-Science Briefing On Harmful Algal Blooms

    To make informed decisions about how to limit exposure to cyanotoxins, utilities need information to select and implement a comprehensive and technically sound management approach. The Water Research Foundation (WRF) has been actively involved in developing effective innovative solutions to help utilities address this challenge and protect public health.

  • How Giving Legal Rights To Nature Could Help Reduce Toxic Algae Blooms In Lake Erie

    August and September are peak months for harmful blooms of algae in western Lake Erie. This year’s outbreak covered more than 620 square miles by mid-August. These blooms, which can kill fish and pets and threaten public health, are driven mainly by agricultural pollution and increasingly warm waters due to climate change.

  • Preparing To Tackle The Hydra Of LCR Revisions

    As a journalist serving the water industry — but not yet a seasoned technical veteran — I attended a recent Lead In Drinking Water Forum sponsored by AWWA NJ to learn about the challenges of complying with the proposed Lead and Copper Rule Revisions (LCRR). What I heard impressed upon me the technical, administrative, and logistical challenges of delivering safe, lead-free drinking water all the way to user taps. Here are my takeaways.

  • New RO And Other Techniques Lead To Improved Performance

    For water utilities facing various water contamination issues, there is no single catch-all treatment. That is why in this recent Water Talk interview Ronit Erlitzki and Doug Craver of AdEdge Water Technologies share treatment options that can be used alone or in combination to address diverse challenges. They introduce a new reverse osmosis (RO) treatment technique capable of raising recovery rates by 20 percent and reducing concentrate volume up to 70 percent vs. conventional RO (depending on water quality). They also explore biological processes for removing nitrate, VOC, ammonia, etc. and treating high brine concentrations in wastewater, plus techniques for resolving ammonia problems in water with high TOC concentrations.

  • Forward-Looking Technology Anticipates Compliance Needs

    When a company stakes its reputation on delivering innovative technologies, products, and services, the specter of a changing regulatory landscape is considered more an opportunity than an obstacle. In this Water Talk interview, Mirka Wilderer, CEO of De Nora Water Technologies, discusses varying topics such as pharmaceuticals and nutrients in wastewater, the synergy of the company’s new MIOX and Neptune acquisitions, and how to address the growing concern over chlorate disinfection byproducts (DBPs) in drinking water. For example, De Nora’s new ClorTec Gen III onsite hypochlorite generators generate up to 3,000 lbs./day of chlorine-based disinfectants while reducing chlorate formation and cutting operating costs by 15 percent as compared to previously available models.

  • Know Your Options For Mag Meter Installation Cost, Care, And Calibration

    Electromagnetic meters (mag meters) are well established in terms of highly accurate performance for a variety of municipal and industrial water applications. Differences in their construction formats, however, dictate how easy they can be to install, maintain, and calibrate. Compare these three options to see the value of full-profile-insertion (FPI) mag meters and their associated advantages in real-world use.

  • Peaking Factors And Hydraulics In Wastewater Screen Sizing

    Dealing with fine particulate matter, nutrients, and pathogens is essential for wastewater treatment plants (WWTPs) striving to meet Clean Water Act (CWA) effluent standards. Before that stage, however, come important considerations about removing larger debris that can clog pumps, overload clarifiers, or disrupt other downstream processes — especially during periods of elevated flow and debris loading.

  • Climate Change And Nutrients: Forewarned Is Forearmed

    Rising temperatures and precipitation combined with increasing nutrient runoff from human activity are elevating challenges in water treatment efforts. In some cases, that means increased threats to drinking water quality. In others, it means increasingly stringent nutrient discharge levels. Either way, taking the nutrient monitoring battle out to the field can help in waging a better fight at the treatment plant.

  • A Guide To Selecting UV Technology For Drinking Water Disinfection

    Selecting the proper lamps to perform disinfection, either low pressure or medium pressure, is at the core of an effective and economical UV implementation. The problem is that a lingering misconception that low pressure is a better choice simply because it is more energy efficient typically sends decision-makers down the wrong path.

  • Achieving Level Pressure At Challenging Points In Distribution Systems

    When drinking water leaves a treatment plant through giant pipes, with the help of huge pumps, the pressure can exceed 200 psi. The high pressure is a necessity because water must travel a long distance in some cases. Water towers scattered throughout the distribution system aid in the process so it can reach all utility customers. The problem is that not all distribution points in a water system are created equal.

  • Flexible Rental Solutions Fulfill Food And Beverage Air Demands

    Some food and beverage operations have been resigned to accepting downtime due to blower failure as inevitable.
