WATER INDUSTRY FEATURES, INSIGHTS, AND ANALYSIS

  • EPA Researchers Explore Technology To Destroy PFAS

    Per-and polyfluoroalkyl substances, otherwise known as PFAS, are a large group of human-made organic compounds with properties that make many of them toxic and persistent in the environment. PFAS have been manufactured and used since the 1940s in items such as fire-fighting foams, adhesives, cosmetics, paper products, and stain and water repellants. Until now, researchers have been unable to destroy PFAS in a way that has potential for larger scale use. 

  • A New Perspective On Funding Nonpoint-Source-Pollution Solutions

    While municipal wastewater treatment facilities fight hard to keep waterways clean, other (“nonpoint”) sources contribute greatly to environmental pollution. But there is funding, and now guidance, available to help solve the problem.

  • In 2022, Water Quality Gets The Attention It’s Due

    With the funding brought forth by the bipartisan infrastructure bill passed late last year, as well as aggressive policies and regulation to rid water supplies of per- and polyfluoroalkyl substances (PFAS) and lead, 2022 shapes up as the year we finally address our industry’s most troubling and challenging contamination issues in a meaningful way.

  • How To Truly Eradicate PFAS From Our Drinking Water

    As so-called “forever chemicals” get more attention from regulators and the public at large, the pressure is on to eliminate these pervasive contaminants — forever.

  • Treating Deep Aquifer Contamination With Phytoremediation

    EPA’s Superfund program is responsible for cleaning up some of the nation’s most contaminated sites. Thousands of contaminated sites exist nationally due to hazardous waste being dumped, left out in the open, or otherwise improperly managed. Superfund sites often have contaminated groundwater in aquifers hundreds of feet below land surface. Deep groundwater contamination can be the result of actions like improper waste disposal or large fluctuations of the water table.

  • Plastic Trash In The Ocean Is A Global Problem, And The U.S. Is The Top Source

    Plastic waste of all shapes and sizes permeates the world’s oceans. It shows up on beaches, in fish and even in Arctic sea ice. And a new report from the National Academies of Sciences, Engineering, and Medicine makes clear that the U.S. is a big part of the problem. As the report shows, the U.S. produces a large share of the global supply of plastic resin — the precursor material to all plastic industrial and consumer products. It also imports and exports billions of dollars’ worth of plastic products every year.

  • State AG Enforcement As EPA Finds PFAS More Toxic Than Previously Thought

    According to a new study conducted by the U.S. EPA, “forever chemicals” are far more harmful than previously believed.

  • Sewage Pollution: Our Research Reveals The Scale Of England’s Growing Problem

    The UK has around 1,500 individual river systems, totaling over 200,000 km, or roughly 124,274 miles, in length. It’s common for sewers here to accept both untreated human waste and rain water in a combined system. Water and sewerage companies are permitted to release this wastewater into inland and coastal waters without treatment under exceptional conditions, such as following heavy rainfall.

  • Extreme Weather, Droughts, And The Impact On Our Water Supply

    Drinking water is obviously affected by the persistent drought plaguing the U.S. — but not just in terms of its supply. Learn the other effects, including degraded water quality, and how to combat them.

  • Addressing Challenges Of PFAS: Protecting Groundwater And Treating Contaminated Sources

    Groundwater is a vital resource across the United States and throughout the world. Over 50 percent of people in the United States depend on groundwater for safe drinking water. Groundwater is also one of our most important sources of water for irrigation and food production.

VIEWS ON THE LATEST REGS

  • With more than 50,000 community water systems (CWS) in the U.S., it is amazing that only 285 individuals had logged public comments on the U.S. EPA’s proposed Lead and Copper Rule (LCR) Revisions by the February 12, 2020 deadline. Yet, what those respondents had to say could have a big impact on how we deal with lead in drinking water moving forward. Here is a cross-section of the industry’s response.

  • Are you completely ready to implement the scores of changes in the U.S. EPA’s Lead and Copper Rule Revisions (LCRR), exactly as proposed? If not, act quickly, because time to register constructive feedback before the February 12th deadline is running out. 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.

  • 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.

  • 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.

  • 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.

  • While it’s well and good to track the known Critical Quality Attributes (CQAs), this industry needs to do a better job to diminish the impact of “unknown” outputs i.e., through stringent process control over “knowns” via the process. Through this control, certain downstream attributes would be less inclined to wreak havoc.

  • I recently wrote an open letter to President Joe Biden requesting a commitment to make the funding of U.S. water infrastructure a priority in his Build Back Better program. I sent a similar open letter to president-elect Donald Trump back in 2016.

  • McCrometer’s Dura Mag flow meter has gained a reputation as a robust tool for flow measurement within irrigation and other markets because of its accuracy and ruggedness while being an economical solution. Several technology limitations prevented the Dura Mag from widespread adoption in municipal water applications, but those issues are about to be addressed as McCrometer is preparing to launch the Dura Mag with expanded capabilities this year, enabling water utilities to take advantage of its benefits.

  • ALTRA Proven Solutions experts believe there are two key areas where they can have a positive impact in helping to eliminate PFAS from our environment: Advocacy and Innovation through ALTRA PFAS solutions.

  • In this application note we consider the issues and describes a test protocol developed to measure the particulate contribution of three different types of insulation during typical cutting and fitting operations within a cleanroom.

  • Historically, OHRP has said that the Common Rule reporting requirements apply to all nonexempt human subjects research covered by an FWA, regardless of funding source. In other words, institutions must follow the Common Rule reporting requirements for activities supported by a Common Rule department or agency, or for "check the box" research. Learn why it is critical for FWA-holding institutions to know whether the box is checked on their FWA and to understand what that means for research at their institution.

  • The identification and quantitation of process-related impurities during biotherapeutic development is critical to demonstrating the quality, efficacy and safety of the therapeutic agent. In this application note, we focus on the accurate detection of four candidate contaminants that may be present during various stages of the therapeutic protein and vaccine development processes: host cell protein (HCP), Protein A, green fluorescence protein (GFP) and bovine serum albumin (BSA).

  • The City of Durham is committed to providing safe drinking water to a service population of more than 289,000.  The City’s Department of Water Management (DWM) ensures the delivery of water to approximately 99,000 service connections through 1,400 miles of watermains. Lake Michie and Little River Reservoir are the two sources that deliver raw water to the City’s two treatment plants, using a combination of gravity flow and electric and hydro-powered pumping systems. Together, these plants have the combined treatment capacity of 64 million gallons per day (MGD) with an average demand is 28 MGD.

  • Granular activated carbon (GAC) and ion exchange (IX) resin have long histories in removing a variety of per- and polyfluoroalkyl substances (PFAS), known as ‘forever chemicals.’ But finding optimal treatment vessel and media efficiency depends on the specifics of the application. Here are some performance considerations of evolving options that can pay dividends for first-time and experienced PFAS removal operators alike.

  • Here we explain explain how passage number and population doubling level are related and provide guidance and tools to help labs adopt the best practice of tracking PDL of cell cultures to help bring standardization to their own experimental protocols as well as to the field.

  • Due to the Revised Lead and Copper Rule and the (eventual?) passing of the Infrastructure Investment and Jobs Act (IIJA), utilities are now required and incentivized to better assess and replace lead pipes within their networks.

  • Mechanical flow meters have always been a dependable option for drinking water treatment and distribution. However, the adoption of ultrasonic devices for these applications is growing steadily as water managers realize that advancements make them a better choice in many cases.

  • Municipal water utilities throughout the U.S. are increasingly grappling with the need to address PFAS once it is detected in source water. Because standards are a moving target while treatment options are limited and can represent a massive expense, addressing PFAS can be especially challenging for small water systems. The key to finding an optimal solution requires a thorough investigation of solutions.
