Antibiotic resistance is a leading cause of hospitalization and death worldwide. Heavy metals such as arsenic have been shown to drive co-selection of antibiotic resistance, suggesting arsenic-contaminated drinking water is a risk factor for antibiotic resistance carriage. By collecting drinking water and stool from mothers and their children (<1 year), the study aimed to determine the prevalence and abundance of antibiotic-resistant Escherichia coli among people and drinking water in high and low arsenic-contaminated areas of Bangladesh. The positive association detected between arsenic exposure and antibiotic resistance carriage among children in arsenic-affected areas in Bangladesh is an important public health concern that warrants redoubling efforts to reduce arsenic exposure.

When Water Quality Crises Drive Change: A Comparative Analysis of the Policy Processes Behind Major Water Contamination Events
This paper explore the delayed policy response to the arsenic crisis in Bangladesh through comparison with water contamination crises in other contexts
Evaluation of System-Level, Passive Chlorination in Gravity-Fed Piped Water Systems in Rural Nepal
This article presents a nonrandomized evaluation of two passive chlorination technologies for system-level water treatment in use in western Nepal. Our findings suggest that whilst safe storage, service delivery models, and reliable supply chains are required, passive chlorination technologies have the potential to radically improve rural household access to safely managed water.
Sustainable management of sedimentation risks in coastal rivers in Southwest Bangladesh: Findings from REACH Khulna Observatory
This REACH policy brief presents recommendations for sustainable sedimentation management in the coastal rivers of Southwest Bangladesh. Working with the Bangladesh Water Development Board and using data from a comprehensive measurement campaign in the Hari-Ghengrail-Sibsa river system, we argue systems-wide management approaches will lead to more effective and sustainable solutions.
Identifying the Sources of Intestinal Colonization With Extended-Spectrum β-Lactamase-Producing Escherichia coli in Healthy Infants in the Community
This study aimed to identify the sources of ESBL-Ec colonization in children < 1 year old through comparative analysis of E. coli isolates from child stool, child’s mother stool, and point-of-use drinking water from 46 rural households in Bangladesh. Interventions such as improved hygiene practices and a safe drinking water supply may help reduce the transmission of ESBL-Ec at the household level.
Fear, Efficacy, and Environmental Health Risk Reporting: Complex Responses to Water Quality Test Results in Low-Income Communities
This paper investigates how water quality information influences water safety management in rural Kenya. The authors find that while poverty threatscapes and gender norms hinder behaviour change, test results can motivate supply-level managers to implement hazard control measures.
Infrastructure alone cannot ensure resilience to weather events in drinking water supplies
The paper presents a novel multi-country empirical study measuring weather impact on water quality. Results show that weather-related shocks affect drinking water quality and health, requiring strengthened climate resilience that addresses management and infrastructure.
Invited perspective: Beyond National Water Quality Surveys: Improving Water Quality Surveillance to Achieve Safe Drinking Water for All (Sustainable Development Goal 6.1)
This perspective summarises a recent paper from the Joint Monitoring Program team (Bain et al. 2021), and recommends three key areas for capacity strengthening to advance water safety toward achieving SDG 6.1: better information through risk-based monitoring, improved institutional clarity on roles and responsibilities, and more investment in mainstream water safety planning.
