According to a recent interpretation of the Clean Water Act, the U.S. EPA won’t regulate pollution that occurs in surface water if it passes through groundwater first.
A politician in Florida thinks he has a new solution that will curb untreated sewage spills in the state: increasing the penalties for those responsible.
It’s not uncommon for the U.S. EPA to step in when local wastewater operations struggle to adequately remove pollutants before releasing effluent into waterways. In Mississippi, however, even that federal intervention has failed to yield enough progress.
After two years under President Trump, the number of civil penalties issued by the U.S. EPA for polluters has dropped significantly.
Following federal charges that he manipulated water sample test results to mask plant discharges, the ex-supervisor of a wastewater treatment plant in Sioux City, IA, plans to plead guilty.
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.
Ultrafiltration (UF) water treatment systems have many possible combinations between the types of membrane configurations, flow patterns, aeration, and submergence. Each design consideration for a UF system has its own benefits that would work for a particular industrial/commercial application, and disadvantages that would work against it.

Due to the dynamics of liquids and gases flowing through elbows, valves, pumps, and other pipeline structures, every flow-meter methodology has its own design limitations. Unlike Venturi meters, pitot tubes, orifice plates, and other devices, V-Cone meters provide highly accurate and reliable readings with minimal straight-pipe length restrictions and virtually no maintenance, in pipe sizes up to 120”.
Installing flow meters in new piping is one thing. Replacing a 20-year-old meter or adding new metering to piping where it never existed before is quite another. In this Water Talk interview, Cheryl Ades Anspach, marketing manager with Badger Meter, offers a non-invasive alternative using easily retrofittable clamp-on ultrasonic meters offering accuracy to + 0.5 percent and flow rates to 33,000 gpm in pipes up to 48” diameter. Two palm-sized rail-mounted transducers provide simpler, more affordable installation than having to shut down or cut into a live pipeline or bring in heavy equipment to install a full-bore mag meter. Built-in datalogging backup (8 GB) with time-date stamp granularity down to one second provides ample opportunity for detailed flow analysis.
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?
Though some preliminary regulations have taken place to curb the presence of microplastics in the environment, more research is needed to determine what role wastewater treatment plants can and will play in solving the problem for good.
With water treatment plant operators around the country relying on paper and pen to record critical quality data, there is an opportunity to make life easier online.
As excess nutrients continue to pollute source water, bringing dead zones and toxic chemicals, it’s time for the disparate agencies that can make a difference to band together.
Over the past 10 years, DC Water has become the harbinger of the modern water utility. It’s often unconventional approach to tackling age-old problems usually elicits one of two responses from other utility professionals. The first response is one of resignation — if only I had the budget that size permits, I’d be able to do similar things. And the second is one of awe — there’s no way I have the amount of gumption to convince regulators or customers that I have a better way.
If forewarned is forearmed, then monitoring risk, resilience assessment, and emergency planning are essential to keeping water flowing in the face of surprise developments. At ACE19, Bentley Systems’ Senior Product Manager Tom Walski shared how the company’s modeling software running as a “digital twin” for water, wastewater, and stormwater infrastructure systems is helping utilities improve daily operation resilience, noting “a little bit of work has a lot of payback.”
When Eielson Air Force Base, located in the interior of Alaska, found high levels of perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS) in their drinking water, they needed a solution that was effective, cost-efficient, and operable in extreme temperatures. Calgon Carbon’s Model 10 adsorption system, filled with FILTRASORB 400 granular activated carbon (GAC), was determined to be the best option.
Once you know Grundfos, you realize the company’s commitment to promoting sustainability is genuine. The global leader in pumps spearheads programs worldwide to help promote the efficient and sustainable use of water and energy.
From the largest metropolitan utilities to the smallest water systems, leaks are a problem everywhere. Because it’s difficult to raise consumer prices to offset the losses, non-revenue water has a direct impact on the bottom line of municipal water systems. However, utility managers now have an opportunity to reverse the problem with advanced flow meter technology that combines multiple measurements.
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.
Corrosion control has always been a priority for distributing safe drinking water throughout the world’s networks of pipeline. This has become all the more critical following the outrageous lead poisoning revelations in Flint, MI — an incident caused directly by corrosion of the city’s lead-based infrastructure.
It’s common to see “BPA Free” labels on water bottles and other containers, a response to consumers who have grown increasingly wary of the contaminant. However, testing for BPAs that may have found their way into drinking water sources has traditionally been cumbersome and expensive, so municipalities could be exposing their customers to unsafe levels. The good news is that newer advancements are making it easier to use existing technologies to monitor for the pollutant.
Affordability and maintainability are two of the greatest challenges small municipalities face when constructing and managing sewer infrastructure. With these challenges in mind, it’s important for small cities to choose wisely when investing in a wastewater system that needs to last for 30-60 years.
Over the past decade, there has been a considerable effort in the water sector to address industry shortcomings through collaboration. And perhaps there’s been no greater initiative to try to help water utility managers in their day-to-day and future planning than the Effective Utility Management (EUM) Initiative.
Among water treatment industry professionals, consensus is growing that small- to medium-scale decentralized desalination and wastewater treatment plants are the way forward in a water-stressed future. But governments continue to announce new water mega-infrastructure projects at an alarming rate. Because the public policy debate appears to have simply not caught up with current technology, many companies and NGOs with a focus on small- to medium-scale water treatment or renewable energy have begun to see the Caribbean as something of a new frontier.
On the banks of Puget Sound and in the shadow of Mount Rainier exists Tacoma, Washington. The city is home to approximately 211,000 residents, making it the third largest in the state of Washington. Tacoma’s vision is one focused on stewardship and resiliency, as outlined the Environmental Services Department strategic plan: “We believe everything we do supports healthy neighborhoods and a thriving Puget Sound, leaving a better Tacoma for all.”
Too many dog owners think their pets’ waste easily breaks down in nature and is helpful to plants, so they leave it on the ground. The truth is that dog poo and other pet waste is loaded with germs such as e. coli and giardia that make people sick as well as nutrients that can fuel problematic algae blooms.
Wastewater service charges vary considerably across EPA regions and States. That’s one of the key findings from the National Association of Clean Water Agencies’ (NACWA) Cost of Clean Water Index. If you live in Montana, Wyoming or the Dakotas (EPA Region 8), your average service charge of $261 a year is considerably less than the $884 your fellow Americans up in New England (EPA Region 1) are paying. As you can imagine, much of the difference is to do with population size and geography.
