Schematic of the pilot-scale IXR-EO treatment train and sampling locations.
This pilot-scale field demonstration evaluated the remediation of poly- and perfluoroalkyl substances (PFAS) from groundwater contaminated with aqueous film-forming foam (AFFF) from a coupled regenerable ion exchange resin (IXR) and electrochemical oxidation (EO) treatment train. A pilot-scale IXR system was used that incorporates a novel resin regeneration process, and recovers and reuses the majority of the regenerant solution using distillation.
Hazard classifications have recently been introduced for persistent, mobile and toxic (PMT) and very persistent and very mobile (vPvM) substances, which are those that negatively impact water resources if substantially emitted into the environment. Many pharmaceuticals and personal care products (PPCPs) may meet this classification. Our study focused on 169 detected PPCPs in surface water, groundwater and drinking water in China among a total of 432 PPCPs that were monitored for across 75 studies.
This paper touches upon virus removal technology for groundwater remediation.

Climate change has affected diverse spheres and its impact is being witnessed worldwide. Soil, the basis of human sustenance, is both directly and indirectly affected by climate change. Soil erosion, vegetation degradation and soil salinisation are becoming prevalent, causing a threat to future food security. Saline soils are found mainly in North and Central Asia, Africa and South America. Various factors such as excess irrigation and poor drainage, groundwater salinity, sea level rise and intrusion, irregular rainfall contribute to the process of soil salinisation.

This study analyzes the effects of a local water market formation on the efficiency of groundwater use productivity. These results demonstrate the role of a market-based groundwater allocation approach under water scarcity conditions.
Components of urban water cycle and probable pathway of the novel coronavirus in water environment.
Increased concern has recently emerged pertaining to the occurrence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in aquatic environment during the current coronavirus disease 2019 (COVID-19) pandemic. While infectious SARS-CoV-2 has yet to be identified in the aquatic environment, the virus potentially enters the wastewater stream from patient excretions and a precautionary approach dictates evaluating transmission pathways to ensure public health and safety.
The use of crop evapotranspiration data has allowed the estimation of crop water requirements and consumptive groundwater use.
Soil and water salinity and associated problems are a major challenge for global food production. Strategies to cope with salinity include a better understanding of the impacts of temporal and spatial dynamics of salinity on soil water balances vis-à-vis evapotranspiration (ET) and devising optimal irrigation schedules and efficient methods. Both steady state and transient models are now available for predicting salinity effects on reduction of crop growth and means for its optimization.
