Though the current U.S. EPA administration is boasting about its action to clean up the nation’s Superfund sites, it appears that it has not done as much as implied.
With cuts being made to the budget of the federal EPA, individual states are having to step up and take matters of protecting drinking and source water into their own hands. Last year, none were more forceful with this change than Ohio.
As the U.S. EPA is reshaped under President Trump, some are concerned over what has been reported as an “exodus” of employees from the agency.
One of the nation’s most high-profile water contamination cases has drawn federal interest, as the U.S. EPA joined an investigation into perfluorinated compound (PFC) pollution in Michigan.
Wastewater pros are using diet soda to track down pollution.
As perflourinated compound (PFC) contamination continues to raise concerns all over the nation, one Michigan community has decided to take action to combat it.
It’s a four-peat.
For the fourth consecutive year, the University of Maryland, College Park has won high honors in EPA’s Campus RainWorks Challenge, a national collegiate competition to design the best ideas for capturing stormwater on campus before it can harm waterways.
Designing an underground stormwater storage system is a unique step in the overall construction process for each site. The size of the inlets and the conveyance pipes are determined by flow rate, elevation, and slope. This information is entered and calculated by stormwater management software to determine the drainage calculation. But many of the measures build upon one another or vary based on different criteria, so it can be a pretty complex process. That’s why we’re going to take a look at the top 10 factors that go into designing and installing one of these systems.
While point level measuring approaches are regarded as simple and user-friendly, they lack the capabilities of more sophisticated continuous measuring instruments.
Growing cities are generating higher volumes of wastewater and putting a strain on clean water supplies, calling for solutions that extract value from “waste” and ensure the sustainability of resources — with the added bonus, or imperative, of protecting the environment.
This video provides a simple overview of the screen’s creation, function, features and benefits. From the beginning, Parkson engineers took it a step further by working with a leading design firm to rethink the industry standard step style screen from the ground up. They reviewed current offerings on the market and improved upon the common weak points. The result is the most durable escalating screen out there – the Aqua Rhino.
A Q&A with Gary Wong, chairman of the SWAN North American Alliance
An MABR is essentially a biological wastewater treatment process that utilizes seemingly passive aeration through oxygen-permeable membranes. Oxygen transfer through the MABR membranes is diffusion based: driven by concentration differences such that oxygen passes from air at atmospheric pressure into water at a higher hydrostatic pressure. This oxygen transfer mechanism, wherein air is supplied to the process at very low pressure, is the reason MABRs have significantly lower energy consumption compared to other wastewater treatment processes, such as conventional activated sludge (CAS), that utilize diffusers. This energy savings is one of the key reasons MABRs are gaining traction in the municipal wastewater industry.
Ralph Spagnolo and Ellen Bryson know their way around the state capitals in EPA’s Mid-Atlantic Region. The regional Water Protection Division employees have been on the road helping states launch an innovative online mapping tool that prioritizes sites for watershed preservation or restoration.

Construction took just five months for this ecologically-friendly municipal desalination plant, designed to treat brackish water with high nitrate levels. Watch as the plant manager speaks about the advantages this system has provided.
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.
The New York City Department of Environmental Protection has compiled a report on the world’s leading stormwater management solutions and challenges. Reviewing its contents can be an opportunity for communities to build stormwater strength together.
Cities all over the country have been prioritizing clean water through a variety of different programs and the City of Brotherly Love is among the ranks.
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.
It may seem farfetched, but the reality is that many Americans don’t have regular access to clean drinking water.
California is home to some of the world’s most creative minds, top universities, productive farmland, groundbreaking industries — and one of the most epic droughts. The state has endured five years of drained reservoirs and groundwater reserves tapped so aggressively that the land subsidence caused by pumping has been literally seen from space. This indicates in no uncertain terms that it’s time to get all hands on deck. Private companies, universities, irrigation and drainage districts, municipalities — it’s time to pull together into public-private partnerships to address water challenges that face California and so many other regions of the world.
To help drive sales, producers of biosimilar medicines seek to gain as much pricing advantage as possible over their products’ reference biological medicines while maintaining as much profit margin as they can. That’s why they are always looking to minimize production costs, especially in raw materials and labor, their largest cost components. While the costs of the former depend on market prices and a buyer’s negotiating skills, the latter can be best reduced through automation and continuous processing.
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.
A Request for Startups post on January 3rd on the Y Combinator Blog caught my eye. The blogger talked about the need to prepare for things to get worse with regard to climate change, and called for applications for funding from those working on new technologies that could inexpensively produce clean water.
It’s no secret that municipalities across the country are facing budget constraints.
More than 20 years ago I wrote a Master’s Thesis about software tools that could be put together with EPA SWMM to create a toolbox for very long term continuous simulation for stormwater and watershed simulations. I was inspired at the time by Dr. William James who was my advisor for that research.
Salvator Mundi sold for nearly half a billion dollars. Walter Isaacson’s latest biography is a breakaway hit. Management guru Michael Gelb’s book accessing the thought techniques of history’s most accomplished Renaissance Man — in every literal and figurative sense of the word — is still a bestseller. Almost 500 years after his death, Leonardo da Vinci is still a superstar.
Straight pipes, failed drainfields, polluted lakes, out-of-compliance discharge permits, and several other indicators of wastewater management issues are widespread throughout Iowa’s rural communities. By Tyler Molatore, Orenco Systems®, Inc.
One of the great turnaround stories in the history of our nation’s water bodies is that of the Chesapeake Bay. Since 1976 when the Environmental Protection Agency (U.S. EPA) first undertook a comprehensive study of the Bay, efforts to address excessive nitrogen and phosphorous degradation of water quality have steadily improved the Bay’s complex ecosystem.
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.
Now that you have returned to the role of private citizen — though, admittedly you are a private citizen with millions of eyes focused on you — I want to encourage you to continue your great work promoting the health of our nation’s children. Your emphasis on exercise and nutrition, jobs and support for veterans, and education have touched millions of Americans of all ages and all backgrounds. Now it’s time to bring in the most common denominator and the first step toward good health — access to clean water.
For a 24-hour-a-day, seven-day-a-week water and waste water management operation, having a supervisory control and data acquisition (SCADA) system is a must. A SCADA system should make workers’ jobs easier, but if it’s not working properly, or it’s unable to keep up as the enterprise expands and upgrades its processes, it becomes a hassle to deal with.
Conversation at the 2016 SESWA Stormwater BMPs, LID and Green Infrastructure Seminar in Atlanta GA that I attended recently touched upon the idea of computers taking our jobs and ‘Engineering Bots’. This has of course happened in other industries, but I didn’t anticipate it happening in the stormwater planning, design and management world.
This blog is a summary of a presentation I gave at the Water Quality Association’s annual convention in Orlando.
Talk about making waves. Cryptocurrency — digital “tokens” or “coins” rooted in computer code and valued for the very fact that they are disconnected from governments and banks — have experienced spectacular rises and falls in recent months. The crypto-economy is already worth hundreds of billions of dollars (REAL dollars!), and it’s anyone’s guess how fast it will grow after that.
