This month, a U.S. appeals court in New York brought back a U.S. EPA rule that allows government agencies to transfer water between various bodies, such as rivers and lakes, without needing to worry about the cause of pollution.
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.
The district manager for the Pinetop-Lakeside Sanitary District (AZ) reports that a special gas chlorination system, featuring unique components and controls, and manufacturer-supplied service, has effectively replaced a chlorine tablet system.
It’s long been thought that the presence of iron in drinking water is a cosmetic problem rather than a public health concern. But some scientists are now saying that while the iron itself might not be hazardous to your health, what it does to your drinking water is.
The Rahway Valley Sewerage Authority (RVSA), which operates a large wastewater treatment plant in New Jersey, embarked on a green co-generation waste-to-energy project to power a portion of its operations. The plant’s management team became interested in pursuing the gas-to-energy power co-generation system for both environmental and cost reasons.
My first full-time job after obtaining my degree in Chemical Engineering started out intimidating, but who ever thought starting off a career in applied microbiology would be easy. As I move through the introductory period of my position — where learning all I can about the field is of top priority — the intimidating nature of the field has started to diminish.
Since our humble beginnings in 2003, we at LuminUltra have always been keenly interested in water quality trends in different parts of the world.
Atlas Copco Rental Oil-Free air compressors created an underwater buffer during the implosion of a San Francisco pier. The San Francisco Bay being a significant ecological habitat in California, words like explosives and implosion generated concern when they were used to discuss how the 80-year-old San Francisco–Oakland Bay Bridge’s 21 piers should be demolished.
Summer reading list a bit dry? Drink up these books on the world’s greatest resources — water.
Both rectangular and circular configurations have been commonly used in clarifier basins. The relative merits of the two have been discussed at length for decades. Historically, the selection of rectangular versus circular clarifiers has been based on past experience and the preference of the design engineer or design company.
Choosing the company that will fill your water service needs is like making any other long-term commitment. It’s important to do your homework, identify the areas that are most important, and take the time necessary to find a good match.
The Global Cleantech 100 identifies nine innovative water/wastewater technologies set to make significant market impact in the next decade.
In a recent column, Water Online Associate Editor Peter Chawaga wrote about a new plan for drinking water safety in the Trump era. In part, he references a late-2016 U.S. EPA Call to Action to improve the safety and reliability of the nation's drinking water.
On a warm December day, I stood in a jojoba field in the Negev Desert in southern Israel and watched water slowly seep up from the ground around the trees. First a tiny spot, then spreading, watering the plants from deep below. This highly efficient system is known as drip irrigation, and I was there to meet with the world’s leading drip irrigation company, Israel-based Netafim.
Farmers in Uganda and in developing countries around the world are facing major energy and waste management issues. There are anaerobic digestions systems to help farmers manage agricultural waste from plants and animals, but there’s a problem.
A new fellowship has been awarded to students researching the latest advances in membrane technology and, perhaps, changing the future of water.
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.
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.
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?
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 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.
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.
