  • Top 5 Drinking Water Issues To Be Resolved

    These comments address five major current topics that U.S. EPA has on its agenda: the Lead and Copper Rule (LCR) proposal, perchlorate, per- and polyfluoroalkyl substances (PFAS), Legionella, and distribution systems. The latter two, Legionella and distribution systems, provide the greatest public health risks associated with drinking water and warrant the highest priorities for management, investments, and health and safety improvements.

  • Wastewater Treatment Plant Realizes The Importance Of Using Genuine Replacement Parts In Its UV Disinfection System (Case Study)

    The UV system installed at the Lucas County Water Resource Recovery Facility includes a total of four banks, with 48 UV lamps per, for a total of 192. The facility was experiencing disinfection inefficiencies and, even after repeated inspection and analysis, staff couldn’t figure out why. They started to question if the issues were stemming from the use of non-OEM, non-genuine UV lamps, quartz sleeves, and ballasts.

  • 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.

  • 4 Benefits Of Sodium Zeolite For Drinking Water Treatment

    Use of treatment systems that effectively target and treat toxic and undesirable contaminants is essential to drinking water production. There are typically four stages in a standard drinking water treatment system process, coagulation/flocculation, sedimentation/clarification, filtration, and disinfection. Sodium zeolite is typically utilized in the filtration systems within the filtration stage for optimal treatment performance.

  • 2020 Industry Forecast: Treatment Moves Down The Line

    It’s no secret that safe and readily available water is important for public health, can boost economic growth and help reduce poverty. But factors such as climate change, growing populations, natural disasters, increasing water scarcity, and urbanization continue to challenge water systems around the world. 

  • 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.

  • PWSA Reduces Customer Request Fulfillment From 4 Months To 14 Days

    Due to recent LCR exceedances, PWSA faced skyrocketing customer requests on top of the order to replace 7% of their roughly 18,000-33,000 lead service lines every year. In addition, their Lead and Copper Compliance (LCR) and Lead Service Line Replacement testing program (LSLR) required immense amounts of manpower. These two events combined to require thousands of point-of-use kits to be collected and tested every year. They looked to 120WA to solve the challenges of siloed data sources, kit delivery and pickup, lab coordination, and distribution of results.

  • The Elected Official's Guide To Understanding The US Lead Effect

    “The water crisis in Flint is the Cuyahoga River fire of our generation: an event that thrust a widespread but underappreciated problem into the national consciousness.”

  • Lead Sampling Program Structures

    We reviewed lead sampling efforts around the country and provide a simple overview to assist as states create or expand lead testing programs for schools and childcare facilities.

  • How Is Zeolite Water Treatment Media Used In Water And Wastewater Treatment?

    Technology is constantly evolving and changing to meet the needs of humanity, and one of those needs is for clean water. The water treatment industry is always researching, testing, and developing new and improved ways in which to treat wastewater and drinking water in ways that are both efficient and environmentally friendly. Zeolite water filtration media is a sustainable, natural treatment solution for drinking water, grey water, and wastewater treatment.

  • Chlorine Method For UKAS Accreditation And DWI Compliance At Welsh Water

    In 2013 the Drinking Water Inspectorate for England & Wales announced that water samples collected in England and Wales must be tested in a laboratory that meets specific standards for drinking water sampling and analysis. At the time of the new instruction, the chlorine method employed at the Welsh Water Bretton laboratory was unable to meet these requirements, notably for the prescribed limit of detection. This prompted the laboratory to investigate new analytical options for monitoring residual chlorine.
