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 […]
News Archive
Welcome to the Fluoride Action Network News Archive. The FAN News Archive serves as an historical repository for fluoride news stories, positive or negative. Since FAN catalogs all news stories on fluoride, our news section remains a reliable database of all published fluoride news.
Our news database is categorized by country, state/province, and industry. This collection of articles is constantly being updated with the most recent global news on fluoride-related issues and events.
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 […]
Arumeru residents get water treatment plant
Water Ministry in collaboration with 02 and B company has donated a water treatment plant to residents of Lemanda village in Oldonyo Sambu ward, Arumeru district. Speaking at a function to install the plant held at Oldonyo Sambu primary school, Arusha disgrict executive director, Dr Wilson Mahera said the plant has been tested by professional […]
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, […]
