In the fall of 2015, a small village on the border of Vermont in New York State, tested positive for Perfluorinated Compounds (PFCs), specifically Perfluorooctanoic Acid (PFOA), in the municipal drinking water. The influent levels of PFOA in the water were above 600 ng/L, and thus considered harmful to village residents. Realizing that PFOA was on the U.S. EPA Contaminant Candidate List, the Village solicited the services of engineering firm CT Male Associates to investigate treatment options and provide a treatment system.

High levels of radionuclides (uranium/radium/etc.) in drinking water aren’t very common, but they are very dangerous. If you’ve long dealt with radionuclides, you’re familiar with the treatment requirements — but are you treating as cost effectively as possible?
The Serum Institute is a global pharmaceutical company that is one of the world’s largest producers of vaccines. The Institute was planning an expansion to their manufacturing plant in Pune, India, that resulted in an additional water requirement for the plant’s needs.
The Birmingham Water Works Board is the largest water utility in the state of Alabama, providing water to approximately 600,000 people across the Greater Birmingham area. Its service area is about 759 square miles and contains about 4,000 miles of pipe.
This is the third installment of a three-part series exploring headworks screening problems and solutions. In this installment we will explore solids removal options for headworks facilities.
In the mid-twentieth century, the idea of operating an electric motor under water was thought to be crazy. But in 1948, Flygt introduced its first submersible pump followed by its first submersible wastewater pump in 1956.
Keeping up with both the water needs and sewage disposal of the Santa Margarita Water District has come with significant challenges, particularly due to both the increase in influent and change in the makeup and durability of the sewage running through the district’s reclaimed-water facility.
When you prepare the Thanksgiving meal, do you ask each person to make a dish of their choosing, with no coordination for an overall cohesive meal? Probably not. Most likely, you plan, because you want everything to fit together.
Carollo Engineers unveils an ambitious plan to turn one of America’s most water-stressed cities into a model of sustainability and resiliency.
Since the industrial revolution, the total amount of waste has constantly grown as economic growth has been based on a ‘take-make-consume-dispose’ model. This linear model assumes that resources are abundant, available, and cheap to dispose of. In the U.S. and around the world, there is a move towards a ‘circular economy’ where products and waste materials are reused, repaired, refurbished, and recycled.
The Drinking Water Cyanotoxin Risk Communication Toolbox takes the guesswork out of public outreach in the event of harmful algal blooms and cyanotoxin contamination.
The U.S. EPA lends advice on how small systems can combat increasingly troublesome PFC contamination.
For water treatment operators and utility officials, the summer months don’t just mean sunshine, pool parties, and barbecues. The season also brings the peak time for algal blooms, the toxic clouds formed in surface water thanks to increased nutrient contamination and rising temperatures. With rising instances of toxic algae around the country and increased regulations for eliminating it, utilities have had to keep pace.
When is the last time you took a moment to stop, and smell your water? A continuous supply of clean and safe drinking water is something that most people take for granted. We rarely go to the tap doubting that the water will be clean and safe. Recently, the general population and water supply professionals have become concerned about the safety and protection of our drinking water supplies.
The students at the University of Miami will know firsthand the importance of rethinking the way we handle wastewater and water with a Net-Zero water treatment system on site. The project showed the viability and feasibility to take buildings off the water grid to provide water recycling and how it can be achieved without raising the cost of high quality water.
A metallically-pure, stress-free surface provides optimum corrosion protection for wastewater treatment plants. Here’s how to get there.
Chemical, petrochemical, and oil-reﬁning plants are process-intensive operations with regulatory requirements to protect the surrounding water and air from the effects of industrial pollution. These external demands are matched by equally compelling internal pressures to address product puriﬁcation needs, ﬁnd alternatives to utilizing costly fresh water in production processes, reduce the carbon footprint, and operate efficiently and proﬁtably.
The U.S. EPA’s Long Term 2 Enhanced Surface Water Treatment Rule (LT2) was adopted in 2006 to modify the Safe Drinking Water Act and more tightly control the spread of Cryptosporidium, a microorganism that can cause gastrointestinal infection if ingested. Since its inception, the rule has posed a treatment challenge to utilities that are susceptible to the tiny contaminant. But which utilities are at risk? And how should they approach treatment?
When Flint Michigan discontinued purchasing water from the Detroit Water Authority and began using the Flint River as their raw water source they unfortunately did not consider the potential impact on lead and copper corrosion and the impact on the public.
We all hope that the Flint Water Crisis – where cost-cutting measures led to the drinking water supply to become severely tainted with lead – was an isolated incident. However, it is not impossible that a similar event could happen again, especially in a similarly desperate city with limited financial resources. Here are a few key points that should be considered to avoid repeating such a tragedy.
The world has watched this summer as countless customers in Detroit have had their water shut off due to nonpayment.
When we humans look at objects we describe them in terms of color. We say that an apple is red or a leaf is green. To us color is an attribute just as surely as the mass or dimensions of an object. But the fact is that color is a pure human construct. Take away the human and it does not exist.
