• 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.

  • 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.

  • 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.
