Louisiana health officials say two water systems in the state tested positive for traces of the so-called “brain-eating” amoeba, a deadly parasite known for striking and taking lives in summertime.
Is the chemical used to replace perfluorooctanoic acid (PFOA) just as dangerous to drinking water as the original?
A probe into perfluorooctanoic acid (PFOA) levels in Hoosick Falls, NY, groundwater uncovered shockingly high levels of contamination.
Fracking poses little threat to drinking water aquifers, according to a new study by The Academy of Medicine, Engineering and Science of Texas.
Lawmakers in New Hampshire took a stand this year against perfluorinated chemical (PFC) contamination, but the effort ultimately failed to cross the finish line.
Lawmakers are putting heat on the Department of Defense (DoD) to address water contamination linked to military bases in their states and districts.
There’s a new wastewater pump in town. Launched at WEFTEC 2016, the Flygt Concerter integrates control panel intelligence inside the pump. Lisa Riles, North America Flygt Product Manager with Xylem, sat down with Water Online Radio at the show to discuss how the new pump works.
Primary and secondary sewage treatment are designed to improve the quality of wastewater. These processes reduce bacteria, suspended solids, biodegradable organics, and other materials to improve effluent quality.
We all hope that the Flint Water Crisis – where cost-cutting measures led to the drinking water supply to become severely tainted with lead – was an isolated incident. However, it is not impossible that a similar event could happen again, especially in a similarly desperate city with limited financial resources. Here are a few key points that should be considered to avoid repeating such a tragedy.
The burden of the unavailability of replacement parts for the aging generators and the FBD basins' high maintenance motivated the Orlando Utilities Commission's Southwest Water Treatment Plant to update and upgrade the plant’s ozone system.
This new smart, interconnected wastewater pumping system from Xylem’s Flygt brand senses the operating conditions of its environment, adapts its performance in real time and provides feedback to pumping station operators.
Dried up reservoirs, cracked dirt and empty swimming pools are just a few of the visual reminders of the ongoing California drought. But what most people don’t see is the water providers, like Mark Sprague at the City of Fountain Valley, working tirelessly to keep the water running.
More long-term data is available than ever before to help wastewater designers and engineers make accurate estimates of up-front costs and life-cycle costs associated with pressure sewer systems. In addition, incorporating extended equipment warranties into project evaluations, specifications, and contract documents is a pivotal tool to help decision makers reveal the true, long-term equipment costs of various sewer system technologies.
A global scarcity of resources is a compelling reason for businesses and people to use raw materials more responsibly. Modern municipal water supply concepts must therefore not only consider such aspects as the structural development of the region and the population’s quality of life, but must also integrate the sustainable use of water in their policy planning.
Mechanical water meters gradually wear down and lose accuracy, preventing you from realizing full revenue potential. Typically, large meters in commercial and industrial services often represent 40 to 60 percent of your revenue, so maintaining their performance is crucial to your operations.
Despite evidence that often points to the contrary, many bodies of water around the country stand as prime examples of how environmental quality can be improved with the proper will and effort.

The U.S. EPA has updated its sampling guidance for determining and fighting against unknown contaminants in drinking water. Here’s why routine preparation can be a utility’s best friend in case of emergency.
Arizona is taking steps to allow for direct potable reuse throughout the drought-plagued state. With the practice legalized for wide use, its popularity around the world may rise.
Updates to a seminal document for running water and wastewater utilities as efficiently as possible call for review by those facing new obstacles.
With Donald Trump appointee Scott Pruitt helming the U.S. EPA, the National Rural Water Association sees an opportunity to free its members from burdensome regulations and change the perception of the country’s smallest water utilities.
The U.S. EPA’s latest roster of concerning drinking water contaminants offers clues into what may be threatening consumers and the regulations that come next.
For water treatment operators and utility officials, the summer months don’t just mean sunshine, pool parties, and barbecues. The season also brings the peak time for algal blooms, the toxic clouds formed in surface water thanks to increased nutrient contamination and rising temperatures. With rising instances of toxic algae around the country and increased regulations for eliminating it, utilities have had to keep pace.
The U.S. EPA’s Long Term 2 Enhanced Surface Water Treatment Rule (LT2) was adopted in 2006 to modify the Safe Drinking Water Act and more tightly control the spread of Cryptosporidium, a microorganism that can cause gastrointestinal infection if ingested. Since its inception, the rule has posed a treatment challenge to utilities that are susceptible to the tiny contaminant. But which utilities are at risk? And how should they approach treatment?
When is the last time you took a moment to stop, and smell your water? A continuous supply of clean and safe drinking water is something that most people take for granted. We rarely go to the tap doubting that the water will be clean and safe. Recently, the general population and water supply professionals have become concerned about the safety and protection of our drinking water supplies.
There have been many publications lately that claim universal appeal of the ORP sensors and their applicability across the board. This concerns me, because the authors sometimes forget to mention some well-known practical limitations of the method, let alone the realities of water treatment applications potentially influencing the sensor performance.
For years, I’ve been standing on my deck in San Francisco, looking south to Silicon Valley for innovation in water efficiency. But I’m starting to realize that I might have been gazing in the wrong direction. Maybe I need to turn around and look north, over the spires of the Golden Gate Bridge, toward the Emerald Triangle in Humboldt, Mendocino and Trinity counties, the hotbed of California’s newly legalized commercial cannabis production.
Chemical, petrochemical, and oil-refining plants are process-intensive operations with regulatory requirements to protect the surrounding water and air from the effects of industrial pollution. These external demands are matched by equally compelling internal pressures to address product purification needs, find alternatives to utilizing costly fresh water in production processes, reduce the carbon footprint, and operate efficiently and profitably.
Water is the lifeblood of electrical power plants, whether they are water-cooled steam plants or turbine-spinning hydroelectric installations. Regardless of how the facility generates electricity, there is a growing awareness that each power plant is part of its own, unique industrial watershed—drawing water from the environment, altering its contents and temperature, releasing some to the atmosphere as steam, and returning the rest to receiving waters.
We all hope that the Flint Water Crisis – where cost-cutting measures led to the drinking water supply to become severely tainted with lead – was an isolated incident. However, it is not impossible that a similar event could happen again, especially in a similarly desperate city with limited financial resources. Here are a few key points that should be considered to avoid repeating such a tragedy.
High levels of radionuclides (uranium/radium/etc.) in drinking water aren’t very common, but they are very dangerous. If you’ve long dealt with radionuclides, you’re familiar with the treatment requirements — but are you treating as cost effectively as possible?
When Flint Michigan discontinued purchasing water from the Detroit Water Authority and began using the Flint River as their raw water source they unfortunately did not consider the potential impact on lead and copper corrosion and the impact on the public.
At the end of The Big Short, a postscript stated that one of the story's protagonists, Dr. Michael Burry (played by Christian Bale), was now focused on investing in only one commodity: water. That got my attention.
