For years, harmful algal blooms (HABs) have posed a threat to drinking water across the country. And now, a tragic incident has illustrated that the problem can have an even more direct effect on our loved ones.
Late last week, the U.S. EPA sent a letter to officials in Newark, NJ, warning them that residents were exposed to dangerous levels of lead contamination in their drinking water and that the city’s efforts to mediate the crisis weren’t working.
Industrial and population growth continue to outpace the supply of freshwater resources in many regions of the world. The need for additional freshwater resources is driving the need for desalination. When combined with concerns regarding climate change and harmful impacts associated with fossil fuels, desalination powered by renewable energy should be considered as a necessary part of the solution.
San Francisco may be best known as a hotbed for the cultural changes of the 1960s and as a hub for some of today’s leading technologies. Now, it is bringing that cutting-edge reputation to bear in the water recycling space.
Following a fire at a major bourbon distillery in Kentucky this month, water treatment workers stepped up to keep a bad situation from becoming even worse.
Are your current pressure-boosting pumps the best design for your operating conditions? Are they maximizing value from your operating budget with peak efficiency? How can you know for sure, and what can you do if they are not? Here are some guidelines for evaluating performance efficiency in pressure-boosting applications and for choosing the best pump configurations for new or existing applications.
In water testing, readings that we believe to be reliable indicators are not always what they seem. Water that exhibits certain chemical or electrical characteristics at laboratory temperatures can provide entirely different readings in the field. Here is a quick review of what to look for in common water tests and why to consider automatic temperature compensation in the instruments used to collect them.
Rising temperatures and precipitation combined with increasing nutrient runoff from human activity are elevating challenges in water treatment efforts. In some cases, that means increased threats to drinking water quality. In others, it means increasingly stringent nutrient discharge levels. Either way, taking the nutrient monitoring battle out to the field can help in waging a better fight at the treatment plant.
The U.S. House has approved an amendment to the annual defense spending bill that would target per- and polyfluoroalkyl substances (PFAS).
Are “ghost forests” a sign of things to come? Rising sea levels and superstorm tidal surges are already impacting coastal areas, with rising salinity levels affecting some drinking water sources. Coastal water utilities are not the only ones that have to worry about salinity, however, as high concentrations of winter storm road treatments, gas drilling, and mining can also generate elevated salinity levels in surface water sources.
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.
Several advancements in solar technology may provide the answer to drinking water production in distressed regions of the world.
For those in the drinking water and wastewater treatment space, the climbing temperatures in summer months can bring with them an obstacle that seems to get worse every year — harmful algal blooms.
Fresh water sources around the globe are becoming increasingly stressed due to population growth, industry use, and changing climate patterns. These stresses drive the need to make the most out of every drop of water available. Water treatment systems inherently produce a waste stream that contains contaminants removed during the treatment process. This waste stream can often constitute 20-30% of the total water fed to the treatment system, representing a significant loss of a precious resource both in human and economic terms. Minimizing this waste stream is a key part of the solution to solving the water crisis for both industry and people.
Saturday, March 24th was a busy day at the Brightwater Clean-Water Treatment Facility in Woodinville, WA, just outside Seattle. The Utility’s Education and Community Center was full of family-oriented science experiments and art projects with organized tours of the wastewater treatment plant taking place throughout the day. All in recognition of International World Water Day which had occurred two days before.
“I know that (blank) is good for me; I just haven’t gotten around to doing it yet!” Most of us can fill in that blank with any number of tasks — modifying diets, exercising, or monitoring commercial and industrial (C&I) water meter accuracy at our largest utility accounts. If that last item is still on your “to-do” list, here are several good reasons why you should do it and how to make it happen soon.
Water doesn’t directly drive profits at industrial plants, but it’s a crucial component of plant operations. Since properly treated water is required, plants must operate and maintain equipment to process their influent and effluent. There are a few options for handling water treatment onsite: hiring and delegating to employees, outsourcing to third-party vendors, or a combination of both. Here are some of the reasons why you might consider outsourcing your water management rather than hiring your own employees for it.
Steve Katz, Market Development Manager at SUEZ, explains how water reuse is being looked at differently today than it was even five years ago. Meanwhile, the stresses on water supply — increasing demand from industry and population growth, often in the face of drought — become more pressing with each passing year. Fortunately, water reuse is on the rise as public perception shifts and treatment technology advances.
There are many options for ensuring accurate billing of water used at established industrial customer locations. But how do municipalities or businesses keep track of water availability and use for intermittent applications or movable access points? We spoke with McCrometer, Inc.’s Marc Bennett for insight into how water utilities and industries can efficiently track and allocate water use for billing or internal accounting purposes in such ad hoc applications.
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.

The federal government recently released its fourth National Climate Assessment which focuses on the impact climate change will have on the U.S. economy over the next century. As mandated by the Global Change Research Act of 1990, the U.S. Global Change Research Program takes a comprehensive look at climate change and its effects on the natural environment, agriculture, energy production and use, land and water resources, transportation, human health and welfare, human social systems and biological diversity.
Data analysis around pipe condition, inflow & infiltration (I&I), and overflows can build a case for the approval of infrastructure funding in budget planning.
Your success as an ISV is always related to how well the applications you develop meet the needs of your clients— but right now in retail, it’s absolutely crucial. Retail ISV growth depends on more than developing simple tools for merchants to use at the checkout or that allow them to accept payments made on a smartphone. Retailers need software solutions that meet the challenges of a rapidly changing, ultra-competitive industry. They need help in the fight to win customers and keep their loyalty. Retail ISV growth requires a deep understanding of the industry and the ability to develop applications that help retailers execute their business strategies.
While utilities use sophisticated systems to supply clean water as well as collect and treat wastewater, the effort to manage incidents and outages leaves room for improvement. Water utilities often rely on manual processes to handle customer reports of leaks, loss-of-service or quality issues. But in many cases, the manual approach can hamper the effort to correlate problem reports to specific assets and locations. The result can be slow response and subpar interaction with customers and other agencies. The solution has emerged from a parallel utility: electricity.
Determining whether a region has sufficient water to satisfy the needs of people who live there is a complicated and imperfect process. Our research team has developed a new approach to measure water scarcity by using satellites hundreds of miles in space.
When a municipality or business wants to reuse their wastewater, some applications require more treatment than others due to the quality of the wastewater. Many standard wastewater treatment systems consist of pretreatment, primary treatment, and secondary treatment stages. By the end of the secondary stage, a majority of the pollutants, solids, organics, inorganics, and metals have been removed or reduced. This is where reverse osmosis wastewater treatment can be utilized in a third stage process.
Wildfire is a natural part of many ecosystems, but recently these fires have become more severe, burning more acres and causing destruction in the western parts of the United States. Recently, U.S. EPA researchers have begun to look at the impact of these fires on our water supply, the natural resource we depend on for drinking, irrigation, fishing, and recreation.
With memories of the wettest U.S. spring on record still fresh, it seems strange to hear that in many parts of the nation, groundwater supplies — the water stored underneath our feet, in rocks, and sediments — are lower than normal. This includes places with wet climates, such as southern Georgia, coastal Maryland, and Cleveland.
A Q&A with scientist Jeff Urban, who explains forward osmosis and how Berkeley Lab is pushing the frontiers of this emerging technology
When validating the 1,000,000 data points that compose the typical Phase III trial, focusing on errors that don’t matter easily leads to wasted resources. Human Factor Analysis (HFA) uses uniquely structured datasets to reveal underlying behaviors and factors that are otherwise difficult for humans to sense or reconstruct, but ultimately are the root cause of an incident. Read how HFA can be incorporated into risk-based monitoring as a useful approach for protecting your clinical data.
This paper will examine foreign object detection in adulteration events, including the detection challenges of finding very small contaminants, in a complex and fast-moving, global supply chain.
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.
Manmade chemicals — most notably PFAS and 1,2,3-trichloropropane, or TCP — are emerging as a serious threat to water sources that municipalities at some point will need to address to meet regulations and provide quality water. PFAS has been rearing its head across the U.S.; and while TCP is mainly a California issue, it could prove to be more expansive. In this Water Talk interview, Jim Knepper, vice president and general manager of the Resinex division of Jacobi Carbons, and Mike Bickel, a municipal sales manager with Jacobi, discuss how activated carbon technology is helping water plant operators tackle looming problems such as PFAS and TCP.
Changing climate and other environmental conditions are intensifying the frequency and severity of harmful algal blooms (HABs). Here are important guidelines to understanding HAB causes and impacts to potable water treatment plants — including dealing with the algal biomass, remnants of decaying algal cells, and especially the secondary metabolites that the algae produce, such as taste and odor compounds and toxins.
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.
Innovation is vital in the water industry and continually moving ahead is a must — even if the company you're trying to surpass is your own. By listening to a wide range of customers and distribution chain partners, Mazzei Injector Company upgraded its revolutionary Pipeline Flash Reactor (PFR) and introduced it to the marketplace with great impact.
Among utilities concerned about resilience and response in natural disasters or other emergencies, precise asset inventory and mapping are high priorities. In truth, there is value in having the same information for everyday purposes as well. For anyone who has ever had a problem locating or tracking key water or wastewater system assets, here are several good reasons and ways to avoid a last-minute scramble.
All the effort and expense required to produce high-quality water can be for naught if the distribution system cannot maintain appropriate pressure to deliver it efficiently, at a reliable flow rate. Simply pumping more pressure into the system is not the answer. Learn how new pressure monitoring options make it easier to track pressure in every zone to deliver customer satisfaction at peak energy efficiency.
Using on-site sodium hypochlorite generation technology to make oxidant for water and wastewater treatment is cost-effective, safe, and environmentally responsible. But, as with any piece of equipment, choosing the right one and caring for it properly impacts both life cycle costs and effectiveness.
