How Aeration Helps Remove Pharmaceuticals During Wastewater Treatment

Among the many contaminants found in industrial and commercial wastewater, active pharmaceutical ingredients (APIs) can be some of the most challenging, both in terms of environmental impact and removal difficulty. APIs are commonly found in effluent from pharmaceutical manufacturing, large-scale livestock operations, hospitals, cosmetics and personal care product manufacturing, and many more.

Wastewater Discharges From Alaskan Cruises Are Putting Ecosystems In Peril

For years, the coastal regions of Alaska have been popular cruise spots. However, the beautiful landscapes and clear waterways the region is known for have become the epicenter of a serious environmental crisis fueled by cruise ship operations. Data from the Southeast Alaska Conservation Council shows that during the 2023 and 2024 cruise seasons alone, 17 ships reported more than 700 violations of federal wastewater discharge limits in Alaskan waters. This shocking frequency of violations is concerning and threatens the region’s long-term environmental health, as well as that of local communities, fragile marine life, and the tourism industry itself.

Arizona Takes Control Over Injection Wells, A Game Changer for Water Security

On September 10, 2025, the U.S. Environmental Protection Agency (EPA) announced a major regulatory shift, granting the State of Arizona primary enforcement authority, or "primacy," over all classes of underground injection wells within its borders. This decision transfers regulatory power for the federal Underground Injection Control (UIC) program from the EPA to the Arizona Department of Environmental Quality (ADEQ). While UIC primacy is usually focused on Class VI wells for carbon capture and storage (CCS), this ruling is most critical for Arizona’s long-term water management and resource protection.

Study Shows Biogas Can Make Wastewater Treatment Carbon Neutral

Although essential to environmental and community health, the wastewater industry consumes incredible amounts of energy and is carbon intensive. Wastewater treatment plants (WWTPs) account for 4% of total energy consumption and 25% of the water sector’s energy use. In the U.S., for example, WWTPs generated 20 million metric tons (MMT) of CO2-equivalent in 2017.

Can Wastewater Help Fuel AI Growth?

The continuous growth of artificial intelligence (AI) and high-performance computing (HPC) is driving a proportional demand for data centers that can manage their substantial infrastructure requirements. This, in turn, presents a significant challenge: balancing the increasing need for computing resources with crucial sustainability goals, particularly regarding water usage. Data centers require substantial amounts of water to prevent their equipment from overheating, which can impact reliability and performance.

Fighting The Foam: Scientists Discover “Dark Matter” Solution

Gordonia amarae and similar bacteria have sticky, hydrophobic outer layers of mycolic acid. It is these layers that are primarily responsible for stable foams. Candidatus Mycosynbacter amalyticus is one of many “dark matter” bacteria, a term used for microbes whose roles and interactions in wastewater environments are not yet understood. It is an “obligate necrotrophic parasite,” which means it specifically derives nutrients by killing its host. Mycosynbacter amalyticus attacks by attaching to the mycolic acid layer of Gordonia amarae and similar species to infect and consume the host. This parasitic action actually reduces the population of foam-causing Gordonia amarae, thereby mitigating the foaming issue

Dolphin Sighting in NYC River Bodes Well for Water Quality

Recent sightings of two common dolphins in New York City's East River have generated excitement and are viewed by experts as a positive indicator of improving water quality. The pair, believed to be a mother and her calf, were first spotted jumping around by people driving on the Franklin D. Roosevelt East River Drive on Feb. 14. Multiple sightings continued through the weekend after.
