When Flint, MI, called for a state of emergency in 2015 over the presence of lead in its drinking water, the city became embroiled in a years-long recovery process that is still underway.
Water officials usually do everything they can to prevent toxic chemicals from entering their drinking water sources. That’s why eyebrows are raising about the Portland Water Bureau’s decision to approve the addition of toxic chemicals to the Bull Run watershed.
An environmental research group with a penchant for uncovering widespread drinking water contamination has released a report pointing to a surprising toxin.
The threat of 1,4-dioxane in drinking water may be more pervasive than many thought and some communities are concerned about the health of their consumers.
Members of Congress are pushing President Trump to speed up the military’s investigation into perfluorinated-compound (PFC) contamination of drinking water.
Another community appears to be struggling with a drinking water contaminant that continues to plague treatment facilities around the country.
No water contamination issue is grabbing more headlines these days than that of perfluorinated chemicals, commonly referred to as PFCs or PFAS. Concerns over the chemicals have sprung up all over the country, prompted by contamination from industrial wastewater and military firefighting foam. Regardless of where the issue has come up or what caused it, everyone who has been affected wants the same thing: an effective treatment solution. To discuss such a solution, Water Online spoke with Calgon Carbon Corporation.
The population continues to grow, demanding more output from fewer resources. This strain is felt acutely in the power industry. New plants are built to accommodate the growing population’s power needs, requiring more water than ever for power generation and cooling. As freshwater resources continue to dwindle, more plants are turning to reclaimed water.
McCrometer’s Full Profile Insertion (FPI) magnetic flow meter inserts into a pipe via a two-inch hot tap, avoiding the need to cut in a full bore mag. As Dan Hardin, Regional Sales Manager for McCrometer, explains in this Water Online Radio interview, it can then connect to any SCADA or radio system the utility might have to measure flow rate to within half a percent accuracy.
The Mississippi River Valley Alluvial Aquifer — a primary water source for small towns, rural water systems and farm irrigation in eastern Arkansas — is running dry. According to the Army Corps of Engineers’ website, a project study in the mid-1980s pointed out, and further studies have since shown, the region’s groundwater resources are rapidly shrinking.
The textile industry in Bahrain dates to ancient times. In the time of Alexander the Great, the country was as known as a producer of clothes seen throughout Arabia and the Indian subcontinent. Modern day Bahrain maintains its strong tradition in textile manufacture.
In June, 2016, a new Love’s Travel Stop opened in Boardman, Oregon, offering professional truck drivers and other travelers 24-hour access to clean, safe places to buy gas, diesel fuel, travel items, meals, and snacks. An essential part of this particular Travel Stop is the private well that provides water for all of the 11,000-square-ft facility’s needs, including food preparation, showers, bathrooms, outside irrigation, and fire hydrants.
The rising marginal cost of producing clean water together with increasing demand and higher expectations of reliability and quality of service leaves utilities facing an uphill challenge — managing aging systems and infrastructure with limited resources.
Most companies and agencies today operate with the concept of business sustainability. This is a holistic way of managing a business that includes environmental, social, and financial responsibilities. To meet this triple bottom line, companies must find ways to be cost-efficient, socially responsible, and eco-friendly at the same time.
Add Pierre, South Dakota, to the rapidly growing list of early adopters of AMERICAN Flow Control’s valves and hydrants with ALPHA restrained joint ends. Introduced last year, ALPHA saves labor, time and money.
Northwest Arkansas has been one of the faster growing regions of the United States in the early 2000s. Driven by the growth of the poultry industry as well as education and health professions, the city of Springdale has seen significant economic and population growth. There is also a thriving leisure and hospitality industry as recreation in the Ozarks continues to grow. The population is now estimated to be approximately 80,000 people compared to 46,000 in the 2000 census.
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.
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.
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.
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.
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?
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.
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.
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.
