    What Is The Future Of Source Water Protection?

    Water utility managers and municipal leaders have long struggled amid the convergence of several threats to public water supplies. During a recent Water Online Live event, I sat with a panel of industry experts to examine the transition from reactive crisis management to a proactive, adaptive resilience framework.

    Drinking Water Contaminated With 'Forever Chemicals' During Pregnancy Linked To An Increased Risk Of Childhood Asthma

    While most of us are routinely exposed to low levels of PFAS, some communities are exposed to far higher levels from nearby pollution sources. A new study shows that in one of these at-risk communities, children were more likely to develop asthma if their mothers were exposed to very high PFAS levels during pregnancy.

    The Pragmatic Shift In Source Water Protection: Moving From Symptom Management To Root-Cause Accountability A shift in how we approach source water protection is long overdue. Currently, we are trapped in a cycle of escalating costs, forced to treat symptoms like algae and invasive weeds expediently with chemicals while the underlying risk in the reservoir compounds. True risk management requires breaking this cycle.

    The AWWA Said $2.4 Trillion. It Missed The Compound Interest. Einstein once said of compound interest, "He who understands it, earns it. He who doesn't, pays it." The same logic of compounding applies to the organic sediment accumulating on the floor of your drinking water reservoir. The longer you wait to address it, the more exponentially expensive it becomes to fix.

    The Future Of In Situ Chemical Oxidation For Targeted Solvent Destruction

    The U.S. EPA’s 2026 trichloroethylene (TCE) compliance deadlines are now forcing a concrete shift toward source-zone destruction. In situ chemical oxidation (ISCO), sequenced with enhanced bioremediation, is proving to be the most credible path to groundwater contaminant rebound mitigation.

    Opinion: Why PFAS Policymakers Should Read Past The Abstract When it comes to drinking water, sound public policy requires sound scientific research. Publication in a prestigious, peer-reviewed journal helps establish legitimacy for scientific claims in public discourse. But science is a social process, scientific standards of evidence vary across disciplines, and peer review does not guarantee validity. For readers who stop at the abstract, these distinctions can be easy to miss.

Water Reuse: Solutions For Sustainability, Efficiency, And Resilient Water Systems

What is water reuse?

Water reuse is the process of treating and reclaiming water from various sources for practical purposes, including groundwater recharge, industrial applications, wetland restoration, agricultural irrigation, public access area uses, as well as drinking water applications. By reusing water, communities can reduce dependence on traditional water supplies, avoid costly imported water from 3rd party providers, and improve resilience in water systems. Thanks to progress in water treatment technology, along with economic and regulatory incentives, water recycling has become a cost-effective and sustainable solution to meet the growing demand for highly treated water and overcome supply shortages during droughts.

There are three primary types of water reuse: Indirect Potable Reuse (IPR), Direct Potable Reuse (DPR), and Non-Potable. In IPR reuse systems, advanced treated water is either injected into an environmental buffer (groundwater, river, or reservoir) before being extracted again for use, whereas DPR is directly blended into the drinking water treatment plant or distribution system. Non-potable water is not intended for human consumption and can be used for irrigation, industrial processes, laundry, or toilet flushing.

Advanced treatment technologies, such as membrane filtration, reverse osmosis, ultraviolet disinfection, ozonation, and advanced oxidation processes (AOP), play a crucial role in ensuring the quality and safety of reclaimed water.

Why reuse water? 

As water scarcity continues to rise, water reuse is an essential strategy for creating a more sustainable future. The use of recycled water reduces the demand for freshwater sources, which are becoming increasingly scarce due to population growth, climate change, and other factors.

Here are some key benefits of water reuse:

  • Safeguard quality and resilience: Reused water is purified well beyond drinking water standards, improving resilience and ensuring quality for both potable and even non-potable purposes.
  • Uphold safety: Treatment processes like ozone and ultraviolet light can be used to disinfect or break down complex contaminants, ensuring water is pathogen-free and concentrations are below maximum contaminant levels (MCL).
  • Ensure cost savings and efficiency: After treating a waste stream to discharge level, it may require less treatment to bring it to reuse standards, making reuse not only environmentally responsible but also cost-effective in many scenarios and locations.
  • Conserve traditional water supplies: By reusing water, we can lessen our reliance on conventional water resources like rivers, lakes, and aquifers, thereby conserving them for future generations.
  • Reduce carbon footprint: Water reclamation is often more efficient than treating a raw water resource, which can lessen environmental impact.
  • Enable versatility and customization: Advanced treatment systems are tailored to meet specific needs for a variety of sectors, including industrial, urban, agricultural, and public access area uses.

How to reuse water 

The major aim of every reuse project is to minimize human health risk associated with the use or consumption of reclaimed water. While the exact treatment requirements depend upon the source water quality and the reuse purpose, to be cost-effective, the treatment must be energy efficient and have a high-water yield.

An adequate treatment design plan depends on the application the water will be used in. In non-potable applications, normally filtration and disinfection will suffice, while potable reuse generally requires a combination of advanced treatment processes such as membrane filtration, reverse osmosis, disinfection, and/or advanced oxidation.

Xylem has brands and solutions to fit every stage of the water reuse process: 

  • beginning with the transport of raw sewage and wastewater with Xylem brands like Flygt

OPUS® II Technology - a New Innovation for High Recovery of Water for Reuse

OPUS® II is a proprietary process for high recovery of complex wastewater streams. This new innovation uses CeraMem® ceramic membranes as pretreatment for reverse osmosis to reduce the system footprint. OPUS II can be delivered in modular, containerized units to minimize installation costs.

Like the original OPUS technology, OPUS II effectively removes silica, organics, hardness, boron, strontium and particulates. It generates high quality effluent at a high recovery rate, providing clean water for discharge, recycle or reuse.

Ion Exchange Resins Reduce Pollution From Refineries

A single operational oil and gas refinery produces millions of gallons of contaminated wastewater a year, leading to environmental pollution concerns. Ion exchange resins are a metal- and ion-removal solution to help clean this wastewater for plant reuse or safe disposal. This application guide explains how resins can be used to demineralize refinery water in process, boiler, and cooling water applications.
