TXST Project Will Launch Floating Wetlands In Lake Kyle To Improve Water Quality

Texas State University researcher Sangchul Hwang, Ph.D., P.E., is leading a City of Kyle-funded project that will deploy floating wetlands to improve water quality in Lake Kyle. The project will test whether this nature-based system can help protect the surrounding Plum Creek Watershed, the land that drains rain and runoff into Plum Creek and connected waterways.

New York City's Water Network Seeks Tech Solutions

The Environmental Tech Lab (ETL) — a public-private collaboration between the NYC Department of Environmental Protection (DEP) and the Partnership Fund for New York City — today launched its fourth annual competition, seeking tech-driven approaches to solve challenges for the nation’s largest municipal water and wastewater system.

Condition Monitoring Agreement Will Protect Welsh Water Assets

Dŵr Cymru Welsh Water (DCWW) has signed a three-year agreement with industrial artificial intelligence (AI) specialist Samotics for the on-going predictive condition monitoring of critical wastewater assets across its estate. This will help the water company intervene much earlier on potential incidents that could lead to pollution and unplanned downtime.

EPA's 14th SepticSmart Week: Practical And Proactive Septic System Maintenance Protects Public Health & Reduces Costs

Today, the U.S. Environmental Protection Agency (EPA) kicked off SepticSmart Week 2026, a nationwide effort to help homeowners properly maintain their septic systems to protect public health, groundwater, local waterways, and the environment while saving American families money. SepticSmart Week 2026 takes place September 14-18, 2026, marking the program's 14th year of promoting practical and responsible septic system care.

New Method Turns Harmful Environmental Waste Into Useful Synthetic Reagent

Fluorinated waste, like that found in firefighting aqueous film-forming foam, can act as a significant environmental pollutant. Recently, James Tour’s lab at Rice University developed a method to capture the fluoride from these waste streams and recycle it into a useful reagent, silver fluoride, that could be used in other manufacturing processes. This process was recently published in Nature Chemical Engineering.
