  • Wastewater Nitrogen Is Causing Ecological Havoc, But The Necessary Innovative Solutions Exist

    The water quality damages associated with excessive nitrogen discharges to our surface and groundwaters that result in life-threatening harmful algae blooms (HAB), the loss of shellfish and finfish, and the degradation of our groundwater drinking water aquifers are now ubiquitous in the U.S. and worldwide. Wastewater nitrogen discharges are typically the elephant in the room when the sources of nitrogen are quantified. Septic nitrogen discharges, in particular, are the primary cause of water-quality/ecological degradation in many, especially coastal, areas.

  • Plastic Pipes Pollute Drinking Water Systems After Wildfires; It's A Risk In Urban Fires, Too

    When wildfires swept through the hills near Santa Cruz, California, in 2020, they released toxic chemicals into the water supplies of at least two communities. One sample found benzene, a carcinogen, at 40 times the state’s drinking water standard. Our testing has now confirmed a source of these chemicals, and it’s clear that wildfires aren’t the only blazes that put drinking water systems at risk. In a new study, we heated plastic water pipes commonly used in buildings and water systems to test how they would respond to nearby fires.

  • 50 Years Of Drinking Water Research

    For nearly 50 years, EPA scientists have done research to support drinking water standards and protect America’s drinking water. However, drinking water systems are increasingly facing new challenges, such as emerging contaminants in source waters that can adversely impact health, including algal toxins from harmful algal blooms (HABs) and per- and polyfluoroalkyl substances (PFAS).

Less than three weeks before the end of the comment period, the EPA’s webpage for feedback displayed only 131 public submissions regarding the proposed regulations.

  • Understanding PFAS’ Impact On Remediation Strategies

    For more than 16.5 million water-utility customers in 33 different states, contamination caused by per-and polyfluoroalkyl substances (PFAS) is a source-water issue that will not go away for a long time. 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.

  • 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.

    The breadth of digital PCR (dPCR) applications continues to grow and fulfill critical scientific needs. One of the major advantages the technology confers is the ability to count nucleic acid molecules directly, rather than extrapolating quantity based on standard curves as with many other methods. By harmonizing diagnostic procedures on dPCR platforms, the scientific and medical communities can become more coordinated and efficient than ever before.

  • How Community Growth And Other Changes Are Driving The Need For Expert Ongoing Field Support

    The process of launching a municipal drinking water treatment operation can take years. In the end, a community is left with a complex system, an operations and maintenance manual, and a well-trained staff. Many communities are extremely well versed in the functions and operation of their treatment for the specific parameters for which it was built. However, as time goes on, plant managers and operators increasingly have a need for outside assistance.
