Electrochemical treatment using aluminum electrodes effectively removes aromatic pollutants from petroleum-contaminated water. Optimized conditions were determined using full factorial design and surface response analysis. This method successfully reduced contaminants to undetectable levels in real water samples, making it a promising solution for remediating contaminated groundwater and surface water.

A study in Nigeria compared the effectiveness of ultraviolet (UV) and chlorine disinfection methods for treating contaminated well water. Results showed UV purification was more effective only when the water was pre-filtered, achieving low microbial counts. Unlike chlorine, UV disinfection did not produce by-products or alter water quality.

Emerging contaminants (ECs) are water pollutants that harm human and wildlife endocrine systems. This review examines various technologies used to remove ECs, with a focus on adsorption, membrane processes, biological treatment, and advanced oxidation. The review highlights current trends, knowledge gaps, and future research directions in the field.

The Rural Water Capacity Needs Assessment examines the challenges facing the rural water workforce, focusing on key gaps in skills and job availability. Significant competency gaps exist in water supply technologies and water quality management, with women identifying additional gaps in areas like financial management. The sector also faces barriers such as job scarcity, insufficient materials, and high data costs, which hinder mobile learning opportunities. The report recommends focusing on technician development, improving training approaches through peer-to-peer learning, and standardizing job roles to improve workforce effectiveness. Further research is needed to address regional challenges and specific workforce needs.

WHO guidelines for small water supplies focus on health-based regulations, proactive risk management, and independent surveillance. These are aimed at decision-makers and stakeholders in water service provision.

The dire situation in Gaza, with high rates of infectious diseases, necessitates immediate implementation of infection prevention and control (IPC) and Water, Sanitation, and Hygiene (WASH) measures. These measures, outlined in a technical note, aim to mitigate disease spread in healthcare and shelter settings by ensuring access to safe water, sanitation, hand hygiene, IPC supplies, and appropriate personal protective equipment. Additionally, the note emphasizes the importance of adhering to cleaning and disinfection protocols, especially in overcrowded conditions.

Groundwater, a vital but slow-replenishing resource, is often overused and needs careful management in the face of climate change. It's a key resource during droughts, but future dry spells and warming trends make predicting availability uncertain. Furthermore, groundwater's potential impacts on climate are largely unknown. More research on the relationship between climate and groundwater is needed for effective adaptation and improved understanding of both.

A study of water samples 538 private water supplies in Virginia found 41% contaminated with total coliforms and 10% with E. coli. Chemical parameters were not predictive of contamination, but well depth, treatment, and farm location were. Four samples were likely contaminated with human wastewater.

The 2023 WHO/UNICEF report focuses on gender inequalities in water, sanitation, and hygiene (WASH) services. It presents data on women's burden of water collection, safety concerns related to lack of sanitation, and menstrual health. It also highlights the need to consider access to WASH services as a gender issue.
