This study investigates the localities of low and high F⁻ groundwaters in the aquifer system on the flanks of Mount Meru to come up with guidelines to provide groundwater that can be used for drinking water supply without health impacts on the population. Our study focuses on parts of the flanks which were only partially or not at all covered by pr...

Understanding of the aquifer structure and its hydraulic properties provides comprehensive knowledge for proper groundwater utilisation and management. This study delineated the aquifer structure using litho-hydrostratigraphical cross-sections, and estimated the hydraulic parameters using single well pumping tests for various locations on and aroun...

This study uses classical solute geothermometry analysis to estimate the temperature and circulation depth of the geothermal reservoir around Mount Meru. Five springs affected by magmatic gases from a deep magmatic heat source are investigated; these include two hydrothermal springs. Results from silica geothermometers show that estimated reservoir...

The integration of remote sensing data, machine learning and geographic information system in managing and analysing spatial data helps in generating maps showing groundwater potential. These maps are important tools for aiding stakeholders and decision-makers in groundwater resources to make informed decisions during groundwater development and ma...

Groundwater recharge maps developed using GIS techniques are important tools that aid the identification of recharge zones. This map must be validated with field data. This study reviewed 63 articles published between 2007 and 2024 to examine the data used to validate these maps and identify the appropriate data for validation. About 50 % of articl...

Freshwater is the most important resource because it is vital for human health, agriculture, the environment, urbanisation, and sustainable economic growth. This study uses time-series analysis of World Bank data for the period 1980–2020 to analyse status of drinking water supply in the African Great Lakes region. The results show that Kenya has be...

This study provides a comprehensive analysis of the groundwater potential of hard rock aquifers in five diverse African case study areas: Lake Tana Basin and Beles Basin in northwestern Ethiopia and Mount Meru in northern Tanzania (comprising volcanic aquifers); the Mekelle area in northern Ethiopia and Jifarah Plain in Libya (consisting of sedimen...

Once mined, gold passes through various stakeholders (from miners to consumers), often erasing origin signatures, resulting in an illegal gold chain. Tracing the origin and all custodians of a given gold bar ensures that fraud, illegal practices, and gold mined by criminal gangs or in conflict zones are avoided. Recently, blockchain technology has...

Non-revenue water (N.R.W) levels exceeding 40% present a formidable challenge to water utilities in Tanzania and other developing nations. To address this, we conducted a comprehensive diagnostic assessment of the Nkuhungu zone served by Dodoma Urban Water Supply and Sewerage Authority (DUWASA), which typifies resource-constrained peri-urban areas...

The Dodoma region located in Central Tanzania is a semi-arid area characterised by scarce surface water resources. Because of climate change and dependence on groundwater resources in the Dodoma urban area, there is currently an increased demand for water due to low groundwater recharge and high groundwater withdrawals due to the growing population...

Despite the introduction of the perimeter blasting technique at the Tulawaka Gold Mine, the mine continued to suffer from an overbreak of mine development headings, with an average overbreak of 24% every 22 m, which is approximately twice the acceptable 10% overbreak. The causes of this problem include ineffective drilling practices and uneven and...

Estimating groundwater recharge, direct runoff and baseflow is essential for understanding groundwater resource availability and managing groundwater systems. This study estimates groundwater recharge, direct runoff and baseflow on two slopes of Mount Meru: the northern and southern slopes using the water-table fluctuation (WTF) method and baseflow...

This study aimed to investigate the hydrochemical and hydrogeochemical facies and mechanisms controlling groundwater quality from the northern and eastern parts of Kilwa district and Songosongo Island in Tanzania. Multifaceted methods were used to analyze the hydrochemical properties of water in relation to local geology and proximity to the Indian...

Groundwater is a very important resource for socio-economic development. The uncertainty of where potential groundwater resources is located often causes some groundwater development projects to fail. It is common for water resources development projects hitting dry wells after heavy investments of resources. In Mpwapwa District, borehole drilling...

The study focuses on assessing the suitability of groundwaters used for irrigation on the flanks of Mount Meru in Northern Tanzania and providing a map showing the spatial variability of irrigation water quality for proper irrigation and crop management in the area. Results of irrigation water quality index (IWQI) show that the groundwaters (F⁻-ric...

Study region Mount Meru located in Northern Tanzania. Study focus Groundwater level monitoring is essential for uncovering the spatial-temporal variation of groundwater levels in a studied aquifer, helping discussions on the sustainable use and management of groundwater resources. This study analyses the spatial and temporal variability of groundw...

In the Arusha volcanic region in northern Tanzania, within the eastern branch of the East African Rift System, water shortage is common and much of the surface water and groundwater contain fluoride (F⁻) concentration above the WHO limit (1.5 mg/L) recommended for drinking water. The groundwater is the main source of drinking water in the area. Pro...

A water quality problem exists in populated areas along the flanks of Mt. Meru in northern Tanzania, with excessively high fluoride (F-) concentrations exceeding the WHO drinking water standards (1.5 mg/L). Little is known about the potential sources of F-among the various rocks types forming the Meru aquifers. Nineteen samples (Debris avalanche de...

The population of the semi-arid areas of the countries in the East African Rift Valley (EARV) is faced with serious problems associated with the availability and the quality of the drinking water. In these areas, the drinking water supply largely relies on groundwater characterised by elevated fluoride concentration (> 1.5 mg/L), resulting from int...

Characterisation of the aquifer and determination of its hydraulic properties is crucial for providing comprehensive knowledge for proper groundwater utilisation and management.

This study characterises high-fluoride groundwater in the aquifer system on the flanks of Mount Meru, focusing on parts of the flanks that were only partially or not at all covered by previous research. Additionally, we analyse the impact of rainwater recharge on groundwater chemistry by monitoring spring discharges during water sampling. The resul...
