Abstract

Significant need exists in the developing world to transition from occasional groundwater-quality surveys to routinely sampled groundwater-quality network monitoring programmes that provide better safeguard of resources. Such networks contribute to the sustainable management of water resources, are integral to Water Safety Plans, and underpin delivery of Sustainable Development Goal 6. A framework for groundwater-quality monitoring network design is developed that is pragmatic for developing-world needs and its application is demonstrated using data from the Chikwawa District � Shire Valley aquifer system in Malawi. The step-wise framework is based upon a hydrogeological�hydrochemical process-based system conceptual model. The Chikwawa model developed is built upon our interpreted 2012 and archive 2008�9 major-ion survey data; major-ion data often constitute the most easily available datasets in many areas of the developing world. A versatile, semi-quantitative, approach is adopted which sets bespoke-system �Monitoring Objectives�, which are weighted on a scale of 1�5 and then rated against bespoke criteria using a scale of 0�10. This permits development of aggregate �Monitoring Potential� scores at candidate network-point localities. Ideally the process is facilitated by the use of a GIS, although its use is not essential. Monitoring objectives are flexible and typically relate to various perceived risks to groundwater quality; including increasing salinity, anthropogenic activity, etc. The framework, as demonstrated for Chikwawa, allows an incremental build of a prioritised network of points, including a relative estimate of their potential to address the individual monitoring objectives set. The framework methodology is easy to use and adaptable to developing, and developed, world monitoring needs alike. The proposed network for Chikwawa could help pilot transition to a higher resolution national groundwater quality network across Malawi than cu

Abstract

Groundwater contamination poses significant challenges to public health and sustainable development in Malawi, where approximately 80 % of the population relies on groundwater sources for drinking water. This study investigates the presence and drivers of nitrate and E. coli contamination in groundwater used for drinking. Analysis was conducted on results from 3388 boreholes/tube wells for nitrate contamination and 2418 drinking water sources drawn from groundwater for E. coli contamination. Overall, 6.11 % and 57.2 % of water-points did not meet WHO guidelines for safe drinking water quality for nitrate and E. coli contamination, respectively. Through a mixed-method approach, utilizing generalised linear mixed models and random forest regression modelling, the study identifies factors relating to sanitation usage as critical drivers of both nitrate and E coli contamination. Pit-latrine usage was identified as a particularly important factor in contamination; accounting for pit latrine density specifically, rather than population density, resulted in better model prediction for both nitrate and high E. coli contamination indicating that consideration of the specific type of sanitation is important in predicting water quality. In addition, a stable isotope tracer analysis method to validate predictions and monitor nitrate in drinking water was piloted, identifying human waste as a likely source of nitrate contamination. Overall, this study underscores the urgency of addressing sanitation-related contamination of drinking water sources to ensure access to safe drinking water in low-income settings., (Copyright © 2024.
