Lead contamination in drinking water, caused by corroded service lines that introduce the constituent after water has been treated but before it reaches consumers, continues to plague cities around the country.
In a sign of just how problematic aging water infrastructure still is for major cities around the country, a National Resources Defense Council (NRDC) spokesperson described lead levels in Newark’s drinking water as “jaw-dropping” and “knock-your-socks-off high.”
Entering its fourth week and now the longest in the country’s history, the partial government shutdown is affecting a wide range of federal employees and agencies. Naturally, water and wastewater treatment operations are no exception.
In a sign of just how significant water quality concerns are in Michigan, the state’s governor elect signed an executive directive related to the issue as her first such move in office.
An increasing number of towns are banning the addition of fluoride to water, a common practice across the country.
The U.S. EPA under Trump administration is considering a major overhaul of how it assesses scientific research, a move that critics say could render the agency more toothless in protecting the drinking water supply.

Olinda's water supply system comprised 8,205 pipes, as well as storage tanks, deep tubular wells, booster pumps, flow rate meters, and other components. Enorsul used WaterGEMS to create a hydraulic model of the system and run what-if scenarios to identify potential solutions and analyze the resulting hydraulic behavior. The project team compiled metering records, conducted field surveys, and collected documents, plans, and drawings to gain a better understanding of the system and network topology. Read the full case study to learn more.
The fallout from Flint, Michigan’s lead-contaminated drinking water has been far-flung and long-lasting.
As with most things in life, there are those water utilities that have and those that don’t. According to the EPA, less than 3% of the 150,110 operational public water systems (PWS) in the U.S. serve more than 10,000 people. And those 4,500 systems serve 79% of the population. Not that being big means living trouble free. Many of these water authorities serve cities plagued by under investment over decades in their water systems. And yet with large rate-bases comes the means to spread the investment in modern technology across many households and water consumers.
When space is tight and straight-run piping is at a premium, V-Cone differential pressure (DP) meters are an excellent choice — especially where the potential for turbulence raises metering accuracy issues with other conventional meter styles. This article describes how to satisfy some challenging water infrastructure applications with V-Cone meter accuracy at a low permanent pressure loss.
The City of Aurora is home to over 370,000 people and is Colorado’s third-largest city. Their wastewater system consists of approximately 1,100 miles of underground piping network.
Aeration for industrial and municipal wastewater treatment involves more than simply moving volumes of air through a treatment basin. It really comes down to creating and sustaining an optimal oxygenated environment for microorganisms to convert oxygen consuming compounds into CO2 and water. Here are some key considerations for making better retrofit decisions about upgrading existing basin capacity and efficiency with jet aeration.
World Water Day (Thursday, March 22nd this year) does a great job of focusing our attention on water issues. And especially with storms on the East Coast and drought in the West, not to mention the looming possibility that officials will have to shut off the taps in Cape Town sometime this summer, a lot of the messaging around water is pretty much like being smothered in a wet blanket.
Reproducible freezing and thawing is critical for successful cell therapies. GE Healthcare’s G. John Morris explains why.
Historically, most fire hydrants sit idle after they are installed. They were there for that one day that hopefully never shows up. But in today’s connected world, fire hydrants are becoming an important asset in understanding the water distribution system, allowing utilities to monitor their water system operation and predict leaks.
The U.S. EPA is gearing up to limit perchlorate in public drinking water systems, so municipalities should start preparing to adopt the appropriate testing and treatment technologies. In a recent report, the agency identified several technologies as the best available to address the perchlorate problem.
When I attended the U.S. EPA-hosted PFAS Summit held at the Horsham, PA high school auditorium on July 25, 2018, the education I received from state and municipal leaders focusing on the local problem was more than just a professional briefing. It was ominously personal, due to the fact that the Water Online editorial office where I work and drink water every day is served by a utility sitting smack-dab in the middle of one of the most concentrated PFAS hotspots in the U.S.
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?
Headlines in 2018 were dominated by the red tide along Florida’s Gulf Coast, which persisted for months, causing human respiratory illnesses, the deaths of dozens of Florida’s beloved dolphins and manatees, and hundreds of millions of dollars in lost tourism revenue and cleanup costs. Here are insights on how to forestall becoming the next city to make national headlines related to harmful algal blooms.
As technology improves, contaminants can be measured in ever-smaller quantities. Pollutants formerly undetected are now becoming emerging contaminants of concern. Water utility managers must stay abreast of potential new regulations and plan for ways to address these contaminants.
Degassing applications in the oil industry are numerous; steam is used in nearly all processes for refining oil. Therefore, water must be treated to prevent scale and pipe pitting through the removal of dissolved ions and dissolved gasses such as oxygen and CO2. Boiler feed water for producing steam must also be free of dissolved CO2 and oxygen; SEPAREL® degassing membranes can remove both gasses in a single compact system.
Finding new ways to capture and utilize data is important for utilities looking to improve operating efficiency and customer service. This interview with Frank Brooks and Dave Rubin from Aclara — a smart-infrastructure solutions partner for water, gas, and/or electric utilities — outlines ways to do both within a common infrastructure.
This article is intended to highlight inconsistencies in testing elastomer vial stoppers — and to drive the collaborative development of a more sensitive, harmonized particle count method.
This article will discuss how the detection limit for analytical methods can be combined with cleaning validation swab limits to create a detectability scale.
With the proliferation of sensors, data collection, and cloud storage, there is the potential for operational insight heretofore never available, and the opportunity will only expand as the technology evolves and the Internet of Things becomes, well, more of a thing. But data is only truly useful if it informs decision-making that results in positive impact — for an organization's bottom line, its personnel, its customers, or even the world at large (i.e., the environment).
Everyone wants good-tasting water, but most water treatment plants (WTPs) are hostages to the composition of their local source water supplies. One of the components involved in taste is total dissolved solids (TDS), which can affect both the acceptability of finished water taste and its likelihood to corrode or clog pipes and fixtures. Here’s how to quantify the problem and what to do about it if it is excessive.
Our planet continues to become increasingly more crowded. Pollution and waste are showing irreversible impact on a global scale, and it has become necessary to come up with solutions in all industries. It is widely known, though perhaps not publicly thought of, that the process of purifying water creates waste. As we remove the minerals and impurities from water, we inherently condense those impurities into a smaller body of water. This waste affects the environment in various adverse ways. The solution lies in a concept known as Zero Liquid Discharge (ZLD).
District Sales Engineer Andy Singer has spent enough time troubleshooting problems in the field that not much surprises him anymore. When it comes to dry barrel fire hydrants, though, he still gets a chuckle out of some of his more outrageous experiences. Here is his educational and entertaining take on the care and maintenance of fire hydrants, and ways to maximize a utility’s return on what potentially can be a 50+-year infrastructure investment.
You’re in the business to offer exceptional service and help your clients operate smoothly. Effectively managing every ticket for every client issue can be time consuming and tough—especially without the proper best practices in place to help.
Understanding the different considerations for bioburden control in various operations and production steps can help define a strategy for successful production.
Surface plasmon resonance (SPR) assays are used across the life cycle of a biopharmaceutical, from target identification, through CQA determination, development, and on-going quality control. This article focuses on concentration assays associated with late-stage development and biotherapeutic drug chemical manufacturing and control.
Globally, over 80% of the wastewater generated by society flows back into the environment without being treated or reused. Clean water is an essential part of daily life, from catchment all the way through to wastewater treatment, therefore analysis throughout the whole cycle is crucial. Whether in lakes, pipes, or bottles, we can accompany you with our range of instruments, test kits and applications for your water and wastewater needs.
Walnut processing inherently runs the risk of including undesirable foreign objects. An effective x-ray inspection system to find and remove those contaminants is critical to brand protection and food safety.
The use of chlorine to treat and disinfect drinking water and wastewater has been in practice for decades, with the earliest recorded attempt dating all the way back to 1893. Since then, it has come a long way.
Traditionally when it comes to analysis, there have been two ways to measure pH. The first is the inexpensive method of using test strips, which requires little time or training. The second requires the use of a pH electrode or probe and because it requires more training, time, and equipment, is far more expensive. However, a hybrid application is now available that brings together the ease of use of test strips with technology to ensure preciseness.
Wastewater plants treat effluent with chlorine as a final disinfection measure prior to its discharge into the environment. While this should be straightforward, there are still a significant number of small water systems facing big problems because they don’t have a solid grasp on the process. The good news is that a modern, cost-effective solution is available.
