  1. A Comparative Analysis Of UCMR 3 And UCMR 5 Of The Top U.S. Water Systems And Their Capital Improvement Projects For PFAS Remediation 1/22/2024

    This article compares the PFAS contaminants present in the third and fifth cycles of the U.S. EPA's Unregulated Contaminant Monitoring Rule (UCMR) for some top water systems in the U.S., based on the population served, to examine the changes in their occurrence and levels over time. We will also discuss the projects by the water systems in their capital improvement plans for PFAS remediation in its water sources and to prevent further contamination.

  2. Destroying PFAS In Wastewater To Help Safeguard Waterways 1/10/2024

    Technologies for the destruction of per- and polyfluoroalkyl substances (PFAS) hold promise, but also face challenges.

  3. Complying With The EPA's First Limits On Toxic 'Forever Chemicals' For Public Drinking Water 1/3/2024

    Monitoring and reporting software helps utilities meet compliance requirements.

  4. Aqueous Vets® Quick Response Keeps Critical Stoneridge Well In Service In Northern California 12/21/2023

    Zone 7 Water Agency is a water wholesaler in Northern California that serves more than a quarter million residents. Blending water from both surface and groundwater sources has enabled Zone 7 to address many emerging contaminant concerns over the past several years.

  5. UK Legionella Risk In RAAC-Affected Buildings 11/29/2023

    One of the UK’s biggest news stories of 2023 centered on RAAC, or reinforced autoclaved aerated concrete. Used widely from the mid-1950s through to the early 1990s, the predicted lifespan of this type of concrete was 30 years, which is why the issue hit the headlines — and why water systems could be at risk.

  6. How PFAS Are Getting Into Miami's Biscayne Bay 11/14/2023

    PFAS, the "forever chemicals" that have been raising health concerns across the country, are not just a problem in drinking water. As these chemicals leach out of failing septic systems and landfills and wash off airport runways and farm fields, they can end up in streams that ultimately discharge into ocean ecosystems where fish, dolphins, manatees, sharks, and other marine species live.

  7. What Is Seawater Intrusion? A Hydrogeologist Explains The Shifting Balance Between Fresh And Salt Water At The Coast 10/13/2023
    Fresh water is essential for drinking, irrigation, and healthy ecosystems. When seawater moves inland, the salt it contains can wreak havoc on farmlands, ecosystems, lives, and livelihoods.
  8. The Do-Nothing Approach To Algal Blooms 10/5/2023
    As a concept in engineering and environmental management, in parallel with solution-proposals, consideration is also given to the consequences of inaction and leaving a challenge unmet with solutions. The "do-nothing" approach to managing algal blooms, therefore, involves taking minimal or no action to actively control or mitigate the effects of algal blooms in natural bodies of water such as lakes and reservoirs. This approach essentially allows nature to take its course, without human intervention.
  9. Invasive Species Cause Billions Of Dollars In Damage Worldwide: 4 Essential Reads 9/29/2023
    Invasive species — including plants, animals, and fish — cause heavy damage to crops, wildlife, and human health worldwide. Some prey on native species; other out-compete them for space and food or spread disease. A new UN report estimates the losses generated by invasives at more than $423 billion yearly and shows that these damages have at least quadrupled in every decade since 1970.
  10. How CERCLA Complicates The PFAS Problem 8/29/2023

    As states and the federal government attempt to crack down on the proliferation of PFAS and their health consequences with a spate of new regulations, there is one significant upcoming ruling that will have tremendous impact for compliance and costs: the final rule on PFAS CERCLA designation.
