Study Evaluates The Cost Benefits Of Recharge Net Metering For Groundwater Sustainability
1/22/2024
In drought-plagued states, scientists and water authorities have been searching for ways to stretch out or replenish water sources. One such method is through managed aquifer recharge (MAR), which involves injecting water directly into aquifer wells, typically from stormwater runoff. MAR projects are a cost-effective way to avoid groundwater overdraws, but often require the participation of private landowners. To solve this, researchers have developed a program called recharge net metering (ReNeM).

A Comparative Analysis Of UCMR 3 And UCMR 5 Of The Top U.S. Water Systems And Their Capital Improvement Projects For PFAS Remediation
1/22/2024
This article compares the PFAS contaminants present in the third and fifth cycles of the U.S. EPA's Unregulated Contaminant Monitoring Rule (UCMR) for some top water systems in the U.S., based on the population served, to examine the changes in their occurrence and levels over time. We will also discuss the projects by the water systems in their capital improvement plans for PFAS remediation in its water sources and to prevent further contamination.

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.
