Last year the EPA implemented new regulations entitled “Mandatory Reporting of Greenhouse Gases.” The new regulations called for certain facilities emitting 25,000 metric tons or more per year of specified GHG’s to provide an annual report of their actual GHG emissions.
Boston Harbor used to be an icon of water pollution in the U.S. But a massive cleanup effort — one of the biggest restoration feats in the nation’s history — has revived the harbor in the last three decades.
If you don’t know what a water hammer is, well, that’s a big part of the problem. It’s an all-too-frequent issue for water systems everywhere, striking in pipelines that are growing more susceptible to failure as they age.
Angelo Mazzei has always thought locally and acted globally. Born and raised in California’s San Joaquin Valley — one of the world’s most productive farming regions — Angelo worked for his uncle’s 10,000-acre farming operation after graduating from college. There he saw a pressing need for a system that would allow farmers to safely and efficiently inject fertilizer into their irrigation water — a task made even more challenging with the 1968 introduction of high-pressure water supplies through the California Aqueduct, a 400-mile-long water conveyance system. A new approach was vital.
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.
Everyone wants pathogen-free drinking water, and adding chlorine is a great way to get it. Unfortunately, the dirtier a water treatment plant (WTP)’s raw water inflow — in terms of natural organic matter (NOM) or microbial organisms — the more disinfection byproducts (DBPs) the chlorination process will generate in the form of trihalomethanes (THMs) and haloacetic acids (HAAs). Those DBPs increase the risk of non-compliance with the U.S. EPA’s Disinfectants and Disinfection Byproducts Rules. Choosing the right instrumentation to measure NOM through spectral absorption coefficients (SACs) can have a big impact on treatment strategies — in terms of both costs and compliance performance.
When California’s AB2022 went into effect earlier this year, allowing the bottling of advanced purified reused water for educational purposes, Orange County Water District (OCWD) and Orange County Sanitation District began the #GetOverIt! campaign to continue to push for consumer acceptance of recycled water systems.
Most of us use computers or smartphones on a daily basis. But we usually don’t know what goes on behind the scenes — the technology that allows us to use cloud computing or even Google search. And we certainly aren’t aware of the infrastructure needed to support that technology — like cooling towers.
Water quality is getting a lot more scrutiny these days. And that’s a good thing says Russ Swerdfeger, Global Director of Memcor Product Management with Evoqua. Alongside his colleague Daryl Weatherup, Director of Marketing with Evoqua, Swerdfeger recently discussed the future of drinking water and the key issues and concerns facing the water industry right now with Water Talk.
One of the more eye-catching events in the water and wastewater industry in 2017 was the acquisition of the GE Water business by SUEZ. Water Talk caught up to Heiner Markhoff, the new CEO of SUEZ Water Technologies and Solutions, to discuss the merger.
