EPA Creates Database To Find Thermal Treatment Processes For Remediating PFAS
Per- and polyfluoroalkyl substances (PFAS) are a group of synthetic chemicals that have been in use since the 1940s. PFAS are found in a wide array of consumer and industrial products. Due to their widespread use and persistence in the environment, most people in the United States have been exposed to PFAS. There is evidence that continued exposure above specific levels to certain PFAS may lead to adverse health effects.

How To Improve Anaerobic Digestion And Turn Sludge Into Renewable Energy
Anaerobic digestion is a critical element in a sludge management plan for wastewater treatment. Its role is to kill any pathogens in the raw sludge, produce a more desirable final product, and enhance the amount of biogas/energy generated by the process. The main issue is how best to improve the sludge quality without incurring excess costs.

The Minimalist Guide to Water Quality Analysis For Biological Nutrient Removal
Nitrogen and phosphorus are two wastewater constituents that, together, pose one of the most high-profile threats for consumers and the environment. An abundance of these elements is what ultimately leads to the formation of toxic algae in surface waters, an environmental issue that regularly gains mainstream headlines and, in some cases, poses an acute health risk to consumers.

Why Municipalities Need A Better Water Treatment Solution
Municipal wastewater treatment is essential for protecting public health and maintaining environmental safety. One of the most crucial steps in this process is sanitization—eliminating harmful bacteria, viruses, and parasites before water is released back into the environment or reused.

LATEST INSIGHTS ON WASTEWATER

People around the globe are trying to figure out how to save, conserve, and reuse water in a variety of ways, including reusing treated sewage wastewater and removing valuable salts from seawater. But for all the clean water they may produce, those processes leave behind a type of liquid called brine. I’m working on getting the water out of that potential source, too.
-
As water systems become more circular and complex, understanding and managing the subsurface — the hidden half of the water cycle — is becoming a critical enabler of resilience. This article explores the key trends shaping this new reality, from tackling “forever chemicals” to the water strategies redefining heavy industry.
-
The White House has finalized plans to roll back rules under the National Environmental Policy Act (NEPA), narrowing its focus and limiting what the current administration claims are needless delays for federal approval of water, energy, and other infrastructure plans. For water and wastewater utilities, the changes could speed up permitting for critical projects, although experts warn the tradeoffs could do more harm than good.
-
Traditional sewer systems, while effective, often require significant capital investment, invasive implementation measures, and complex maintenance. As a result, innovative decentralized wastewater solutions are necessary to address the needs of communities or commercial areas in need of wastewater service. One such solution is the liquid-only sewer (LOS) system.

While many scientific and technical reports show that floods are becoming larger and more common, reports underestimate how their frequency is changing. Flood sizes get the spotlight, but governments and experts need to also consider their frequency to address implications overlooked by traditional management methods.
-
In areas with storm drains, the water can quickly overwhelm the drains, causing flooding hazards. For this reason, many towns have ordinances dictating how much ground can be covered with impermeable substrates.
