Apparently, one of the most unsettling water treatment reports to make headlines last year was even worse than many realized.
As Pittsburgh faces high lead levels in city drinking water, Pennsylvania is considering a proposal to increase state oversight of the struggling water system.
Residents in North Carolina recently marked their 1,000th day without access to clean drinking water in their homes.
In laying out the U.S. EPA’s agenda for 2018, Administrator Scott Pruitt indicated that the agency would focus on scaling back Obama-era clean water regulations while ramping up the fight against lead contamination in public drinking water.
New Jersey’s top environmental regulator says alleged failures at Trenton’s water utility could pose a threat to public health.
One of the first communities to raise a red flag around perfluorinated compound (PFC) contamination took another step in its fight for clean water this month.
Accurate and dependable water metering is more important than ever for today’s water utilities. Although utility managers are tasked with meeting tight budgets, it is imperative for utilities to invest in their water metering infrastructure. When making meter selection decisions, utilities must consider several factors. These include service size, application, and expected flow rates. There is no “one type fits all” application when it comes to meter technologies.
Water utilities throughout the world must deal with the issue of non-revenue water (NRW), which can seem like a never ending battle. One of the largest contributors to NRW are leaks from pipes and other assets such as valves or hydrants, that can be caused by aging infrastructure, cold weather, and soil erosion. Water main breaks are not only a waste of water as a precious resource, but can also be dangerous and life threatening.
Xplore has been in the rugged mobility business for more than 20 years. In fact, we’re the only manufacturer that has exclusively designed and delivered rugged tablet-based mobility solutions for global industry for more than two decades. So, we know rugged. It isn’t something we “also” do like many other device manufacturers that also build and sell an extensive lineup of non-rugged or desktop computers, or even vacuum cleaners or air conditioners.
Reverse osmosis (RO) membranes are widely used in potable water, wastewater, and industrial applications. However, a major issue in the application of RO membrane technology for desalination and wastewater reclamation is membrane fouling. It limits operating flux, decreases water production, and increases power consumption. Membrane fouling also increases the need for RO plants to perform periodical membrane CIP procedure. These problems decrease process efficiency, increase operation cost, and raise environmental issues related to the CIP solutions disposal.
Water utilities must protect the public health by producing a final product that meets all regulatory requirements. In addition, the water must be pleasing to the customer, with no taste or odor issues. And finally, utilities must stay abreast of emerging contaminants, health advisories, and new regulations. It’s a constant challenge to shoulder these responsibilities while staying within tight budgets. Utilities need a technology that helps them achieve multiple goals cost-effectively.
There are many types of water meters being used across the U.S. to measure water consumption. And even though the panacea for a water utility would be to equip each residence with the same meter — standardizing metering technique, data capture and maintenance — the reality is that a utility needs to be able to read and service the variety of meters that make up its metering portfolio.
Many organizations don’t consider how secure, managed connectivity plays such a key role in today’s business environment. When I speak with businesses leaders - from both large enterprises and innovative start-ups - I find that wireless failover capability hasn’t always been considered in their business continuity plan, yet it can sometimes make the difference between success and failure.
A rising number of small cities are adopting smart water meter technology as a way to cut costs.
There’s a lot to be said for the old adage, “Use the right tool for the job.” When it comes to flow meters for municipal or industrial water treatment plant (WTP) and wastewater treatment plant (WWTP) operations, however, the sheer number of choices can be overwhelming. That is where using a process of elimination to winnow out styles that don’t fit the performance criteria of an application can make it easier to compare the few remaining options. Here is a checklist of considerations to accelerate that process.
Nearly every industry requires water and wastewater treatment to some degree. From food and beverage to pulp and paper operations, influent and effluent must meet certain conditions to adhere to regulatory and/or performance requirements, and water used during the process must conform as well.
Nick Burns, director of water treatment technology for (the Americas region of) Black & Veatch, discusses the health concerns, current regulatory status, and documented presence of perfluorinated compounds (PFCs), also sometimes called perfluoroalkyl substances (PFAS), in drinking water supplies — as determined by sampling under the U.S. EPA's Unregulated Contaminant Monitoring Rule 3 (UCMR3).
By now, just about everyone in the U.S. has heard about Flint, Michigan’s water woes. Despite the many issues raised by that incident, urban water systems are not the sole reason the 2017 Report Card from the American Society of Civil Engineers gives the U.S. drinking water infrastructure an overall “D” grade. Hidden within that disheartening rating are the harsh realities faced by rural water systems.
It’s no secret that the U.S. EPA has changed course in the last year. But how have those changes affected local water and wastewater treatment operations? And how are those operations going to evolve along with the federal agency?
PFC contamination is the number one drinking water issue today. So how are local and federal leaders working to put an end to it?
Last year was full of twists and turns for the drinking water and wastewater treatment industries. What can 2017’s biggest stories tell us about what’s to come this year?
A couple of weeks ago, Environmental Protection Agency (EPA) administrator Scott Pruitt called PFAS groundwater contamination “a national priority” and pledged action at an EPA national PFAS leadership summit.
In a nation of red states and blue states, water policy is an issue that often dissolves party lines.
Following these five rules will ensure that OOE investigations are conducted in a scientific and meaningful manner, with each instance providing a genuine opportunity for improvement.
Angelo Mazzei has always thought locally and acted globally. Born and raised in California’s San Joaquin Valley — one of the world’s most productive farming regions — Angelo worked for his uncle’s 10,000-acre farming operation after graduating from college. There he saw a pressing need for a system that would allow farmers to safely and efficiently inject fertilizer into their irrigation water — a task made even more challenging with the 1968 introduction of high-pressure water supplies through the California Aqueduct, a 400-mile-long water conveyance system. A new approach was vital.
Discover the steps you can take to improve the quality of your chromatography sample prior to performing your column separation, to ensure optimal isolation of your target protein.
Since chlorine technology was first used to disinfect drinking water in Jersey City, NJ, in 1908, most waterborne diseases have been eliminated in the U.S. Chlorine is still the most common disinfectant for drinking water and wastewater. Chlorine is also used for disinfection and as a biocide in numerous industries.
In the wastewater treatment industry, coagulation has become one of the most widespread processes for effectively separating contaminants and effluent. But coagulation is a complicated and sensitive process, one that alters the chemical balance of the wastewater in order to strip it of unwanted constituents. As in many such processes, pH plays a critical role, and treatment professionals must analyze it closely if they want to properly coagulate their product.
Despite quality audits and third-party oversight, contamination of prescription and over-the-counter (OTC) pharmaceutical products is still prevalent. This article evaluates various emerging practices to overcome contamination issues.
Food manufacturing companies invest millions of dollars annually into food magnetic separation equipment, proactively reducing the risk that any foreign object or contaminant will be embedded into a food product sold to grocery stores, restaurants, retailers, or general consumers. Manufacturers of food industrial magnets have adopted standard testing equipment that measures the holding force of a magnet. Here are some rules to follow to make sure you are using standard operating procedure when field testing magnetic strength to attain the most accurate results.
The Al Hosn Shah Gas Processing Plant in Abu Dhabi is a natural gas processing plant that purifies gases by removing certain contaminants in a sweetening process. The gas pipelines and other infrastructures that process sour gases need to be continuously monitored for leaks as the contaminant gases are often dangerous for human exposure. This case study explores the innovative combination of UAV and FLIR optical gas imaging technologies as an efficient way of monitoring vast gas fields from the air.

Evidence indicates that manganese (Mn) is more than a nuisance: it's a threat to health. It's time to get serious about removing it from drinking water.
Total nitrogen (TN) has become a compound of concern because of its impact on eutrophication on water sources. And as more states begin to set limits for TN, accurate testing becomes paramount. Unfortunately, multiple labs and variable test procedures can lead to disparities in final results. Many of today’s test methods are also time consuming, expensive, and even unsafe for lab technicians to use.
The overall wastewater treatment process is complex, and each step is integral to ensuring water is properly purified. Effluent ends up in the plants, containing substances that must be removed before the water can be properly cleaned and returned for use. The range of potential contaminants is almost endless, and can include food, pulp, waste, or other substances. Afterwards, the water requires further scrubbing, with the aid of bacteria. It is in this part of the process that compressed air (ideally provided by energy-efficient rotary lobe blowers) plays a vital role.
Just as different water utilities use different processes for turning raw source water into potable drinking water, so too do they take different routes to account for, and bill for, their output. Here is an overview of a cellular-based approach to collecting and leveraging data from water distribution operations that can achieve the greatest business advantage.
Water utilities rely on accurate and dependable flow measurement for critical process controls. Regulatory agencies also require flow monitoring and reporting, with specific accuracy limits.
