Hydrogeochemical and isotopic controls on the source of fluoride in groundwater within the Vea catchment, northeastern Ghana
Highlights Fluoride is dominant in K-feldspar-rich granitoid and hornblende-biotite granitoid. Almost 61% of the samples from the Vea catchment are contaminated with fluoride. Groundwater is supersaturated with respect to albite due to silicate weathering. Silicate weathering, ion exchange, and alkaline pH control fluoride enrichment. Stable isotopes indicate meteoric origin with an evaporative effect for groundwater. […]

Underground water sources under siege of substance pollution-CWSA
The activities of illegal miners is not only affecting surface water quality but underground water as well, Mr. Wolanyo Kwadjo Siabi, the Chief Executive Officer of the Community Water and Sanitation Agency has indicated. “Underground water which over the years have been described as the safest, had had its quality compromised with traces and continual […]

Upper East Region has favourable ground water potential – Survey
Bolatanga, Oct. 31, GNA – The Upper East Region generally has a favourable groundwater potential with a low fluoride content that can serve the people for a long time, a survey carried out in the region has revealed. Mr John Nedjo, a consultant and leader of the survey team, said the ground water in parts […]

Assessment of fluoride concentrations in drinking water sources in the Jirapa and Kassena-Nankana Municipalities of Ghana
Highlights Natural groundwater is not necessarily safe for drinking. Fluoride concentration in groundwater sources ranged from 0.6 to 2 mg/L. High fluoride concentrations in groundwater in the Upper East Region of Ghana. 1.8% of boreholes in the study area have high fluoride concentration (>1.5 mg/L). 1.5% of population in the study area are exposed to […]

Groundwater fluoride contamination and probabilistic health risk assessment in fluoride endemic areas of the Upper East Region, Ghana.
Highlights Over 20% of the existing wells have fluoride >1.5 mg L-1. Probabilistic risk assessment of fluoride exposure was carried out for different age groups. Fluoride concentrations, daily ingestion rate and exposure time were the most relevant variables. There should strong advocacy and public awareness on the effect of water quality on human health. Abstract: […]

Water For All Declared In Bongo District By The Year 2025
Mr Peter Ayamga Ayinbisa, District Chief Executive for Bongo has stressed that government has put up a comprehensive water supply programme to address the water needs of the constituents in the Bongo district. He envisaged that access to water supply would increase from current 84.7 per cent to 100 per cent by 2025. To fulfil […]

Determining the optimum locations for pumping low-fluoride groundwater to distribute to communities in a fluoridic area in the Upper East Region, Ghana
Abstract: Groundwater is the primary source of water in the Upper East Region of Ghana, and is generally considered a safe source of drinking water; but there are pockets where the groundwater contains high concentrations of fluoride due to the dissolution of minerals in the local granite. The goal of this study is to evaluate […]

Need for interdisciplinary approach to address environmental challenges
Accra, Nov 3, GNA – Dr Emmanuel Arhin, Head of Department of Earth and Environmental Sciences, University of Development Studies, Navrongo has called for an interdisciplinary research approach to address environmental health problems confronting the country. Dr Arhin said it was imperative for stakeholders to ‘walk the talk’ and take effective action to curb the […]

Fluoride Removal from Groundwater by Adsorption Technology. The occurrence, adsorbent synthesis, regeneration and disposal.
Note from Fluoride Action Network: “Since all methods [to remove fluoride] produce a sludge with very high concentration of fluoride that has to be disposed of, only water for drinking and cooking purposes should be treated, particularly in the developing countries.” Reference: Fluorosis (see Interventions), World Health Organization Excerpts from dissertation titled : Fluoride Removal […]

Fluoride removal from groundwater by adsorption technology: the occurrence, adsorbent synthesis, regeneration and disposal
Abstract In the Eastern corridor of the Northern region of Ghana, the presence of high fluoride concentration in the groundwater has made many drilled boreholes unusable for drinking. Little is, however, known about the factors contributing to the occurrence of high fluoride in the groundwater. Fluoride-contaminated groundwater can be treated by adsorption, but is hampered […]
