Analyzing the Impact of Different Filter Media for a Recharge Well in Harvesting Rain Water

This study evaluates three rainwater harvesting filter designs at the University of the Punjab, finding that while most parameters met quality standards, the bio-char-based F2 design failed due to excessive electrical conductivity, highlighting the critical importance of selecting appropriate filter media for sustainable groundwater recharge.

Multi-proxy records reveal rapid atmospheric reorganization during Dansgaard–Oeschger events

This study utilizes high-resolution multi-proxy records from the GISP2 ice core to demonstrate that rapid, large-scale atmospheric and hydrological reorganization, rather than a specific sequence of source-driven changes, primarily drove the abrupt climate fluctuations observed during Dansgaard–Oeschger events.

Operational Service Conditions are the primary predictors of Household Water Service Quality Across Heterogeneous Provision Systems

Based on a comprehensive analysis of over 6,000 households in South India, this study demonstrates that operational service conditions—such as water pressure, clarity, and complaint resolution—are the primary predictors of multidimensional household water service quality, significantly outperforming traditional access-based indicators and household priorities in explaining service deficiencies across heterogeneous systems.

Tissue-Specific Microplastic Burden, Concentration and Size Distribution in Labeo rohita from Taunsa Barrage, a Ramsar Wetland in Pakistan

This study reveals that in *Labeo rohita* from Taunsa Barrage, microplastic distribution varies significantly by tissue type, with the gastrointestinal tract holding the highest absolute burden while gills and muscle exhibit the highest mass-normalized concentrations and smallest particle sizes, respectively, highlighting the necessity of multi-tissue analysis to accurately assess contamination risks.
