Springfield, CT, is having significant problems when it comes to its sewage system. It pumps large amounts of pollution into the Connecticut River, which in turn sends it flowing south through the state and into the Long Island Sound.
For some time now, West Virginia lawmakers have been working toward legislation that could allow more toxic discharge into their waterways.
A Pennsylvania state law requiring that public water systems be informed of nearby gas drilling spills saw its downfall late last month.
This month, a federal judge struck down the Des Moines Water Works' pollution lawsuit against drainage districts that are in three northwest Iowa counties.
A wastewater operator in Massachusetts was indicted for falsifying environmental test results between 2013 and 2015.
West Virginia’s House Bill 2506 was voted on earlier this month and opponents have said that it could put West Virginia’s drinking water supply at risk.
Recently, ASCE released its Infrastructure Report Card, giving the nation’s drinking water infrastructure a D: in poor to fair condition and mostly below standard. Many water utilities and communities are doing the hard but necessary thing in finding the resources to upgrade their aging water infrastructure. And, for those in earthquake prone areas, hopefully considering an earthquake resistant system.
Fox Thermal Flow Meters use a constant temperature differential (constant Δ T) technology to measure mass flow rate of air and gases.
America’s water infrastructure is in a state of disrepair, as evidenced by disasters such as the public health crisis in Flint, Michigan and dangerous flooding at the Oroville Dam.
Regulatory pressure, water scarcity and public health concerns have increased the use of ozone as a primary disinfectant and essential oxidant, making ozone a key treatment process in municipal water, wastewater and recycling facilities. Mazzei’s ozone dissolution systems are designed to work with a facility’s ozone generators to provide safe and rapid transfer of ozone gas to solution.
The Pipeline Flash Reactor™ utilizes patented technology supported by extensive research at leading universities. Providing high ozone mass transfer in a small footprint design, the Pipeline Flash Reactor™ is ideal for municipal plant flows ranging from 2 to more than 200 MGD.
The preferred method for rapid transfer of ozone gas into solution and subsequent removal of undissolved gases.
The Mazzei GDT™ Degas Separator is a patented unit that utilizes centrifugal force to create a vortex enabling entrained gases to be extracted from water. The water-entrained gas mixture enters the top of the separator tangentially and flows through an accelerator plate, which increases velocity. The water spins down through the separator and exits the bottom. The entrained gas travels through the vortex where it passes into a collector and flows out the top of the separator. The separated gasses exit the separator through a degas relief valve.
The JCS Industries Model 4180 All Vacuum Chemical Feeder is for operations that require high efficiency, accuracy, control and safety. The Model 4180 will feed chlorine dioxide solution used in municipal and industrial water treatment systems.
Three models for continuous monitoring of critical parameters for early warning at wells, pump stations and throughout the distribution system. A complete panel with high quality components; A reliable monitor for potential problems.
When a piece of process equipment needs to be replaced, it is tempting to go with a straight replacement in kind – same manufacturer, same model, just the latest version of “the same”. But often, full consideration of other options opens new possibilities for your treatment plant. That was certainly the case for Plainfield, Indiana.
The U.S. EPA has a job to do despite having its financial and human resources trimmed by the new presidential administration. Three U.S. EPA Office of Water directors, presenting at the 2017 Water & Wastewater Equipment Manufacturers Association (WWEMA) Washington Forum, laid out action plans for addressing the nation's most pressing water-quality threats in a manner that can (or must) achieve results efficiently.
Micropollutants like PPCPs are known to pass through waterways and contaminate the environment. Some wonder what threat they pose as they find their way into biosolids and, eventually, into our soil.
Researchers from Iowa have developed a system that utilizes algae for wastewater nutrient removal and gives utilities a chance to offset costs with the process.
Updates to a seminal document for running water and wastewater utilities as efficiently as possible call for review by those facing new obstacles.
With the change in administration comes a potential paradox for water and wastewater treatment in the oil and gas industry: Will increased production accompanied by decreased regulations call for more treatment technology or less? Either way, the market is poised for change.
The U.S. EPA has updated the list of approved test procedures that can be used to analyze wastewater for compliance under the Clean Water Act.
Election season is in full swing and while it may not be the “hottest” topic being debated amongst presidential candidates, the topic of water isn’t being ignored as we approach November. Several candidates have addressed the challenges plaguing water and wastewater systems nationwide.
For years, I’ve been standing on my deck in San Francisco, looking south to Silicon Valley for innovation in water efficiency. But I’m starting to realize that I might have been gazing in the wrong direction. Maybe I need to turn around and look north, over the spires of the Golden Gate Bridge, toward the Emerald Triangle in Humboldt, Mendocino and Trinity counties, the hotbed of California’s newly legalized commercial cannabis production.
During the long campaign, you ran on a platform of change, and since the election, you have charted a course toward improving our nation’s infrastructure. I urge you to focus some of that change and a significant portion of those infrastructure improvements on the one issue at the center of survival for all Americans, regardless of whom they voted for — water.
It may seem farfetched, but the reality is that many Americans don’t have regular access to clean drinking water.
Summer reading list a bit dry? Drink up these books on the world’s greatest resources — water.
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.
While most of the country was seeing red, white, and blue this past Fourth of July, many Florida residents were seeing green.
As part of its Long Term Control Plan to reduce combined sewer overflows (CSOs) to the Merrimack River, the City of Nashua, NH constructed a new Screening and Disinfection facility (SDF) to reduce untreated discharges of CSOs to the Merrimack River.
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?
Last month I tipped my hat to America’s rural water districts in the blog post Rural Water Systems: Dancing Backwards and in High Heels. As Americans prepare for Independence Day, it’s a perfect time to salute some truly unsung American heroes: the people who operate our nation’s drinking water and wastewater treatment plants.
Despite evidence that often points to the contrary, many bodies of water around the country stand as prime examples of how environmental quality can be improved with the proper will and effort.
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.
While the term “Water Resource Recovery Facility” may seem like nothing more than a trendy phrase, the name change represents a distinct shift in the role that wastewater utilities can now play.
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?
About 30 years ago, a Frank and Ernest cartoon tipped its hat to Fred Astaire while giving long-overdue credit to Ginger Rogers. “Sure, he was great,” said a lady in front of a movie theater sign touting a Fred Astaire film festival, “but don’t forget that Ginger Rogers did everything he did…backwards and in high heels.”
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.
Living near water requires that we plan for situations when we have too much of it. Throughout history we have dealt with flooding when weather events exceed “normal” parameters.
Loudoun Water, a water utility serving customers in Loudoun County, Virginia, recently undertook an innovative, green approach to supplying water in the face of game-changing growth and development.
