The Trump administration is showing little concern about pesticide contamination despite mounting evidence that an unregulated bug repellant poses a threat to drinking water.
A small region of North Carolina suffered over fifty sewage spills last month, but that was just one aspect of the fallout from recent flooding events that demonstrated the complexity of stormwater management.
The U.S. EPA is planning to overhaul a rule governing the treatment of toxic metals in power plant wastewater.
Minnesota is often called the Land of 10,000 Lakes. Yet even in this relatively water-rich state, officials are considering a more expansive role for water reuse.
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.
Wisconsin is beginning a major new push for policies limiting phosphorus pollution in waterways.
Wastewater researchers have an unusual new tool at their disposal: bathtubs pumped full of speed.
Water recycling for agricultural use is about to get a major boost through a massive reuse project in California that marks some first-evers.
As the U.S. EPA seeks feedback on what it should prioritize under the new administration, a clear message is coming from the public: Clean water must be a major focus.
As Utah struggles with water scarcity, the state is having trouble with a key tool for managing this issue: water data.

Tucson residents are gearing up for a legal battle over whether chemical contamination of tap water is making them ill.
This is the third installment of a three-part series exploring headworks screening problems and solutions. In this installment we will explore solids removal options for headworks facilities.
The design of a utility’s ozone disinfection system often includes a method to minimize the production of regulated oxidation by-products that may form when ozone contacts the water. In regions where water contains a significant concentration of bromide ion (Br¯ ), ozone disinfection systems often minimize bromate (BrO3¯ ) formation by modifying the water chemistry through the addition of chloramines, acid, or other chemical additives.
It’s just past 10 on a Friday night, and the phones start ringing in the pockets of the on-call collection systems operators. It’s an alarm for another pump clog at one of your sewage lift stations — the second one this week.
While most of the country was seeing red, white, and blue this past Fourth of July, many Florida residents were seeing green.
As some of you may have heard, LuminUltra has partnered with Microbe Detectives to offer DNA testing services to the drinking water and wastewater industries. So “Who’s on First?” (pun intended); simply put, the partnership’s combined technologies tell you who is in a given water or wastewater sample, and how much is in that sample.
Air/gas mass flow meters find a variety of applications in many of today’s large urban water treatment plants, both clean water and wastewater. From measuring disinfection gases to controlling air or gas flow in digesters and aeration systems, the proper application, installation and operation of mass flow meters improves process efficiency as well as end product quality while at the same time reducing plant operating costs
Recently, the United Nations held a conference in Morocco related to climate change issues. The location of the conference had significant meaning because Africa has become a bellwether for the rest of the world when it comes to climate change. Desertification and rising sea levels both impact countries all over that continent.

Operators of a wastewater pumping station at Sultan Qaboos University in Oman were facing serious clogging issues, having to frequently lift the station’s pump and manually remove waste solids and grease build-up.Furthermore, as the station couldn’t handle the flow during peak hours, it was not unusual to have overflows that would reach the adjacent roads.
The third version of KROHNE’s Waterflux meter introduces temperature and pressure measurement to enhance its leak detection capabilities. In this Water Online video, Rich Lowrie, Water and Wastewater Industry Manager for KROHNE, explains the benefits of adding temperature and pressure to traditional flow measurement.
A genetic tool has been developed to help water systems understand the root cause of arsenic contamination.
With public safety of primary concern, real-time sensors may be the catalyst for assurance and expansion of potable reuse treatment schemes.
A chasm in the Clean Water Act, coupled with EPA’s misguided direction, create an environmental suing spree that threatens to cost everyone that pays a sewer bill $100 billion and more — for pollution you didn’t cause, using remedies that don’t work. There’s a way to turn this around and help the taxpayer and the environment, based on lessons learned in Iowa and Idaho.
A new report from the Oklahoma Water Resources Board’s Produced Water Working Group indicates that oil and gas companies looking for ways to dispose of large volumes of wastewater should focus on recycling those liquids within the oil and gas fields, and not use it for irrigation or other surface applications where human and environmental exposure is a risk.
Water-related business risks are becoming more and more apparent. According to CDP’s 2016 global water report, 607 companies lost $14 billion last year alone due to water scarcity, drought, flood and other water risks.
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.
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?
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.
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.
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.
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.
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?
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.
