Identification of low fluoride areas using conceptual groundwater flow model and hydrogeochemical system analysis in the aquifer system on the flanks of an active volcano: Mount Meru, Northern Tanzania
Highlights F–-rich NaHCO3 groundwater affects drinking water quality. Groundwater flow conceptual models for different flanks of Mount Meru Magmatic degassing has an influence on the groundwater chemistry. Map showing low F– zones on the flanks of Mount Meru Abstract This study investigates the localities of low and high F– groundwaters in the aquifer system on […]

Spatial variability of the sources and distribution of fluoride in groundwater of the Sanya alluvial plain aquifers in northern Tanzania
Highlights Debris-avalanche deposits dynamics trigger the widespread of fluoride in groundwater. Depth to groundwater enhances the variability of fluoride in volcanic aquifers. Safe groundwater for drinking purposes exists at steep slopes of stratovolcanoes. Deep fractured aquifers are potential sources of safe fluoride water. Irrigation agriculture enhances the variability of fluoride in shallow aquifers. Abstract Groundwater […]

Assessment of fluoride removal in a batch electrocoagulation process: A case study in the Mount Meru Enclave.
Abstract The presence of excessive amounts of fluoride than prescribed standards has been reported in various sources of domestic water supply around the slopes of Mount Meru and other parts in Tanzania. Efforts to remove the excessive fluoride have been carried out using various technologies. In this study, electrocoagulation experiments were carried out to assess […]

Spatial analysis and GIS mapping of regional hotspots and potential health risk of fluoride concentrations in groundwater of northern Tanzania
Highlights Fluoride occurence in groundwater systems of the study area is space dependent. The univariate local Moran’s I statistic has been used to identify significant regional hotspots and cool spots. Geoinformation on hotspots and cool spots is important for planning of new safe drinking water source development. Fluoride is mobilized from volcanic igneous rocks of […]

Spatial distribution of arsenic, boron, fluoride, and lead in surface and groundwater in Arumeru district, Northern Tanzania
Abstract: This study was carried out in Arumeru district, to provide the critically missing information that could aid in the improvement of water quality policies, management practices, and public health protection. The physico-chemical parameters and the fluoride concentration for springs, rivers, lakes, boreholes, and dug wells were determined on 101 samples while the arsenic, boron, […]

The Path to Universal Fluoride-Free Drinking Water in Tanzania
Abstract: Fluorosis has been prevalent in the great East African Rift Valley (EARV) since before this region was given a name. In the Tanganyika days, Germans reported elevated fluoride concentrations in natural waters. In the 1930s, the clear relationship between high fluoride level and mottling of teeth was established. Since then, the global research community […]

Simple Test For Fluoride Can Help Prevent Crippling Bone Disease
A simple test to detect fluoride in drinking water quickly could prevent skeletal fluorosis, a crippling bone disease, according to a team of researchers from the Centre for Sustainable Chemical Technologies and the Water Innovation and Research Centre (WIRC) at the University of Bath, UK. The study is published in the journal Chemical Communications. Fluoride is […]

Tanzania: Experts Begin Research On How to Counter Effects of Fluoride
An intensive research on ways to counter the health effects of flouride on human health is underway here. Scientific researchers from Tanzania, Ethiopia, Kenya and the European Union (EU) are involved. The lead researcher, Prof Giorgio Ghiglier from the Cagliari University in Italy said flouride affects humans when consumed through water. The animals, including livestock, […]
