Mapping With Molybdenum: Using Sediment Characteristics To Understand Hypoxia In Estuaries
12/27/2023
Many factors can affect dissolved oxygen concentrations and hypoxia can vary greatly over space and time. To better understand the link between hypoxia and nutrient inputs, U.S. EPA scientists are using a surprising method — measuring molybdenum in surface sediment as an indicator for hypoxia throughout the water above it.

Assessing Methods Of Measuring Microplastics In Water
12/19/2023
Microplastics have been found in surface waters worldwide — including in ponds, rivers, and the ocean. However, our ability to characterize microplastics in the environment is limited by the lack of technologies for rapidly and accurately identifying and quantifying microplastics. Although standard methods exist for collecting and preparing microplastic samples, the methods for analyzing samples and actually identifying microplastics within the sample are not as robust.

These Cities Are Testing Small-Scale Treatment Systems And Wastewater Recycling
12/15/2023
A lot can go wrong in a large urban water system. Pumps malfunction. Valves break. Pipes leak. Even when the system is functioning properly, water can sit in pipes for long periods of time. Water shortages are also a growing problem in a warming world, as communities across the Southwestern U.S. and in many developing nations are discovering. That's why cities have started experimenting with small-scale alternatives — including wastewater recycling and localized water treatment strategies known as decentralized or distributed systems.

The Role Of Reverse Osmosis (RO) Membranes In The Battle Against PFAS
12/4/2023
As the global concern over per- and polyfluoroalkyl substances (PFAS) contamination continues to escalate, innovative solutions are becoming increasingly pivotal in the pursuit of clean and safe water resources. The City of Rome Water and Sewer Division conducted a comprehensive pilot to identify a treatment process for removing PFAS from the water supply, including high recovery reverse osmosis technologies.

UK Legionella Risk In RAAC-Affected Buildings
11/29/2023
One of the UK’s biggest news stories of 2023 centered on RAAC, or reinforced autoclaved aerated concrete. Used widely from the mid-1950s through to the early 1990s, the predicted lifespan of this type of concrete was 30 years, which is why the issue hit the headlines — and why water systems could be at risk.
