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.
Water Quality
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.
Drinking Water Quality in Bangladesh | 2021 Updates
This report shares key findings from the Bangladesh Multiple Indicator Cluster Survey (MICS) 2019: Water Quality Thematic Report, based on water quality testing and survey carried out in 2019 by Bangladesh Bureau of Statistics in collaboration with UNICEF and icddr,b.
Global prospects to deliver safe drinking water services for 100 million rural people by 2030
This report documents a global diagnostic survey to evaluate the status and prospects of rural water service providers from 68 countries.
River pollution and social inequalities in Dhaka, Bangladesh
This study seeks to understand the socio-spatial and seasonal inequalities in pollution risks in Dhaka, Bangladesh. The authors designed a direct observation method to record people’s daily river use activities across dry and wet seasons, complemented by monthly monitoring of river water quality, heavy metal and biotoxicity assessment a large-scale household survey along a 25km stretch of the Turag River and Tongi Khal in Dhaka, Bangladesh.
Optimizing rural drinking water supply infrastructure to account for spatial variations in groundwater quality and household welfare in Coastal Bangladesh
This study examines decision-making to invest in drinking water infrastructure in coastal Bangladesh, where increasing saline intrusion in aquifers intersects with high levels of poverty for the 20 million people living in the coastal region
Natural and anthropogenic sources of salinity in the Awash River and Lake Beseka (Ethiopia): Modelling impacts of climate change and lake-river interactions
This study simulated chloride concentration in Ethioia’s Awash River Basin by taking both natural and anthropogenic sources of salinity into consideration. Future scenarios of climate change and Lake Beseka discharge were examined to assess the impact to the river water quality.
Report on findings from the Awash River basin
This report provides an update on REACH’s work in the Awash Basin up to November 2020, and introduces our programme of research from 2020-2024.
Petrography and Geochemistry of the Rocks in Lodwar, Kenya and their Influences on Groundwater Quality
This paper evaluates the influence of rock chemistry on groundwater quality in the region of Lodwar County, Kenya. Rock geochemistry influences groundwater quality and the aquifer processes of an area. Therefore, this study used conventional petrography and geochemistry techniques to measure the mineralogical compositions of 69 rock samples. The geological study area comprised of quartzo-feldspathic gneiss and biotite gneiss of the Precambrian basement, as well as sedimentary Turkana Grits and Holocene sediments, Tertiary volcanics comprising nepheline phonolites and augite basalts, alluvial deposits along the banks of major Streams and laggas. Quaternary sands also blanket much of the area. The results demonstrate that that geological factors and processes have location-specific influence on groundwater quality. These should be considered in aquifer water-quality studies and supply development across Africa’s vast ASAL regions.
Drinking water services in coastal Bangladesh
This report presents empirical evidence on the existing state of drinking water services in coastal Bangladesh, highlighting challenges and opportunities for reforms in the institutional design, information systems, and sustainable finances under the proposed ‘SafePani’ model.
