The Air Force has acknowledged plans for addressing the higher-than-normal concentrations of perfluorinated compounds, or PFCs, that a base near Colorado Springs sent into the city’s sewer system as frequently as three times a year.
Using fast-track procedures, Congress killed an Obama administration regulation aimed at protecting streams from mining waste earlier this month.
The city of North Pole, AK, has plans to expand its water system to cover residents affected by a major sulfolane spill at a former refinery.
Vermont lawmakers are debating who should pick up the cost of ensuring clean drinking water after a contamination event.
Last month, both U.S. Senators Charles Schumer and Kirsten Gillibrand signaled for the U.S. EPA to “prioritize and accelerate” the risk evaluation for 1,4-dioxane, a potential carcinogen found in 71 percent of Long Island water supply systems.
A $2 billion paper and fertilizer plant is currently under construction near Richmond and is considered to be the first of its kind. Not only is it the first U.S. venture for a Chinese company but it is also the first project to test Virginia’s ability to add new industrial facilities to the Chesapeake Bay watershed while maintaining pollution caps set for the James River.

Melaka is a relatively small state on the southwest side of the Malay Peninsula with a city so rich in history and beauty that it is listed as a UNESCO World Heritage site. With a population around 850,000, the Melaka Water Company Ltd. (SAMB) manages roughly 270,000 service connections for commercial and residential customers.
Where there’s a problem, there’s a solution. Sometimes it just takes a little ingenuity to get there. When you’re in the business of providing solutions to municipal and industrial water resource recovery utilities, then it’s helpful to invest in ingenuity.
Utilities are under constant pressure to reduce costs, meet regulatory requirements, and improve sustainability. Finding the best way to meet these goals is a constant challenge. Endress+Hauser has been helping water and wastewater utilities achieve their objectives for many years, and spoke with Water Online to discuss how to save
energy in today’s wastewater treatment facilities.
The turning point for Rudy Engert came when Georgia ran out of water. Faced with severe water shortages, the state was literally weeks away from water rationing. Engert decided it was time to think about the water and wastewater industry differently.
Electrodeionization (EDI) is a cutting-edge water treatment process that is now used all over the world. While it’s become the solution of choice for countless operations, it’s not exactly worry-free to utilize. When complications arise with performance optimization, it can be difficult to know where to turn.
Lead in drinking water has become a very visible issue of considerable concern over the last few months. While municipalities across America have been scrutinizing the quality of their drinking water, it should at least be some consolation that manufacturers of measurement instrumentation have taken serious steps to assure that they are not contributing to the problems that have been encountered.
To increase capacity within the existing footprint of a wastewater treatment facility in Michigan, two existing tanks were converted to aeration tanks with pure-oxygen aeration provided by Praxair’s In-Situ Oxygenation (I-SOTM) System.
Water management professionals know all too well that problems arise — usually sometime after 2 a.m., or just as you’re walking out the door for a holiday weekend. No matter how well-prepared you are, or how sophisticated your system, sometimes you’re going to run into challenges. It’s simply the nature of the industry. When you experience an issue with your valves (especially when they’re failing to open or close as expected) your first instinct is to call the factory for support. While some cases may require factory assistance, this isn’t always the most efficient solution.
As some of you may have heard, LuminUltra has partnered with Microbe Detectives to offer DNA testing services to the drinking water and wastewater industries. So “Who’s on First?” (pun intended); simply put, the partnership’s combined technologies tell you who is in a given water or wastewater sample, and how much is in that sample.
The U.S. EPA’s latest roster of concerning drinking water contaminants offers clues into what may be threatening consumers and the regulations that come next.
A U.S. EPA “call to action” for improving drinking water seems to lay the groundwork for the new president to address public health.
Polyfluoroalkyl and perfluoroalkyl substances like PFOA and PFOS have emerged as the contaminants of greatest concern for many consumers. While the U.S. EPA has issued a health advisory with limits on the chemicals, some affected communities wonder if their restrictions go far enough. So, what is an acceptable amount of PFOA in your drinking water?
With winter snow comes the inevitable introduction of a water source foe: road salt. With potential hazards posed to consumers and the environment, it’s up to treatment plants and utilities to do something about it.
Many drinking water utilities have made or are considering the switch from chlorine to chloramine to avoid regulated disinfection byproducts. However, the Water Research Foundation warns that chloramination presents its own set of problems.
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.
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.
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.
There have been many publications lately that claim universal appeal of the ORP sensors and their applicability across the board. This concerns me, because the authors sometimes forget to mention some well-known practical limitations of the method, let alone the realities of water treatment applications potentially influencing the sensor performance.
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.
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?
