  1. Moving Toward Sustainability: Perfecting Wastewater Pretreatment For Direct Potable Reuse 2/13/2024

    This article will explain why pre-treatment is so important to direct potable reuse and the most important aspects of pre-treatment design.

  2. Geospatial Patterns Of Antimicrobial Resistance Genes In The EPA National Rivers and Streams Assessment Survey 2/6/2024

    Both antimicrobial products and antimicrobial-resistant bacteria find their way into the environment through the release of treated wastewater into rivers and streams, as well as through runoff from animal feeding operations. EPA researchers are engaged in a variety of efforts to understand what happens when antimicrobial-resistant bacteria (sometimes referred to as antibiotic-resistant bacteria) are released into the environment.

  3. Agriculture And Pharma Key To Solving Micropollutants 1/31/2024

    As the phrase "forever chemicals" enters the Oxford English Dictionary for the first time in 2024, and these fluorinated substances expand the list of micropollutants, it might be time for a change in the way these persistent environmental pollutants are tackled.

  4. Humans Are Depleting Groundwater Worldwide, But There Are Ways To Replenish It 1/25/2024
    Groundwater is a renewable resource, but it can take decades or even centuries for some aquifers to recover after they are depleted. Current understanding of this challenge is based mainly on where and how frequently people record measurements of water levels in wells. In a newly published study, our team of data scientists, water specialists, and policy experts compiled the first global-scale dataset of these levels.
  5. EPA Researchers Develop Forecasting Approach To Predict Harmful Cyanobacterial Blooms For U.S. Lakes 1/23/2024

    Due to climate and land use pressures, there is concern that harmful cyanobacterial blooms (HCBs) may increase in frequency, extent, and magnitude, but it can be difficult to know when and where HCBs may form. EPA’s Safe and Sustainable Water Resources research uses a range of data sources and methods to characterize HCBs in waterbodies.

  6. 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).

  7. 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.
  8. Destroying PFAS In Wastewater To Help Safeguard Waterways 1/10/2024
    Technologies for the destruction of per- and polyfluoroalkyl substances (PFAS) hold promise, but also face challenges.
  9. Complying With The EPA's First Limits On Toxic 'Forever Chemicals' For Public Drinking Water 1/3/2024
    Monitoring and reporting software helps utilities meet compliance requirements.
  10. 5 Concerning Contaminants Found In Your Drinking Water 1/3/2024

    Contaminants can enter water in a variety of ways. In this article, read about the measures that can be taken to reduce exposure and contamination.
