An analysis released this month by the Environmental Working Group (EWG) shows that dioxane is found in drinking water in 45 states, afflicting over 90 million people in the U.S.
Water quality is getting a lot more scrutiny these days. And that’s a good thing says Russ Swerdfeger, Global Director of Memcor Product Management with Evoqua. Alongside his colleague Daryl Weatherup, Director of Marketing with Evoqua, Swerdfeger recently discussed the future of drinking water and the key issues and concerns facing the water industry right now with Water Talk.
In a nation of red states and blue states, water policy is an issue that often dissolves party lines.
The design team for the intermediate ozone system at Buckingham Water Treatment Plant, Quebec, had limited space available for ozone contacting for the plant’s 1.3 – 7.4 MGD flow, so a standard fine bubble diffusion basin for ozone disinfection was not an option.
Those in the water industry know water is essential for life and brings economic value, but the economic role of water is often not as well understood by the general public. This paper reviews the history and development of our transportation, electrical, and energy infrastructure and then presents a plan for our nation’s water to be augmented from where we have it abundantly to where we badly need it.
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.
It’s long been thought that the presence of iron in drinking water is a cosmetic problem rather than a public health concern. But some scientists are now saying that while the iron itself might not be hazardous to your health, what it does to your drinking water is.
In spite of the recent abundance of water, many of California’s aquifers continue to balance on the edge of water scarcity. Decades of overpumping have reduced the amount of ground water available to supplement surface water resources diminished by drought. The Pure Water Monterey Ground Water Replenishment Project (Monterey Pure), addressed the need to replenish a local aquifer, by piloting Advanced Water Treatment (AWT) processes, to determine the best method to convert secondary wastewater into a pure water resource.
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.
It has been five years since I first published this post on World Water Day to remind the general public on how they can play a role in conserving one of our world's most precious resources. It is as relevant now as it was then.

The U.S. EPA has a job to do despite having its financial and human resources trimmed by the new presidential administration. Three U.S. EPA Office of Water directors, presenting at the 2017 Water & Wastewater Equipment Manufacturers Association (WWEMA) Washington Forum, laid out action plans for addressing the nation's most pressing water-quality threats in a manner that can (or must) achieve results efficiently.
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.
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.
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.
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.
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?
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.
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.
