In the heart of Ghana’s Vea catchment, a silent health crisis is unfolding, one sip at a time. High levels of fluoride and nitrate in groundwater are posing significant health risks to local communities, and new research is shedding light on the urgent need for action. Led by Musah Saeed Zango from the Department of Geological Engineering at the University for Development Studies, this study, published in Discover Environment, delves into the hydrochemistry of the Vea catchment, particularly in the Bongo area, to understand the spatial distribution and health implications of these contaminants.
The Vea catchment is not alone in its struggle with high fluoride levels in groundwater, but the specific health risks and spatial distribution in this area have remained largely unexplored until now. Zango’s research, conducted using advanced modeling techniques and Geographic Information Systems (GIS), reveals a stark reality. “The hazard quotient values for fluoride are alarmingly high, with 68.6% of children and 57.1% of adults at risk,” Zango explains. This means that a significant portion of the population is exposed to levels of fluoride that can lead to dental caries and skeletal fluorosis.
But fluoride is not the only concern. Nitrate levels are also a cause for alarm, with 11.4% of children and 4.3% of adults facing potential health risks. The hazard index (HI) values are even more concerning, with 95.7% of children and 82.9% of adults in the area at risk. The carcinogenic risk (CR) of nitrate is also high, at 75.7% for children and 87.1% for adults. These findings underscore the urgent need for intervention to protect the health of the local population.
The implications of this research extend beyond public health, with significant commercial impacts for the energy sector. Groundwater is a critical resource for many industries, including energy production. Contaminated groundwater can lead to increased operational costs, regulatory fines, and reputational damage for companies operating in affected areas. Moreover, ensuring a safe water supply is essential for the well-being of workers and local communities, which can in turn enhance productivity and social license to operate.
The study’s findings highlight the need for targeted action to provide fluoride-free drinking water to the people within the catchment. This could involve identifying and tapping into uncontaminated aquifers for safe groundwater supply, as well as continuous monitoring of existing boreholes. The research also underscores the importance of regular hydrochemical studies and spatial characterization of contaminants in groundwater, not just in the Vea catchment, but in similar areas across the globe.
As we look to the future, this research could shape developments in the field of water management and public health. It serves as a call to action for policymakers, industry stakeholders, and researchers to prioritize the monitoring and management of groundwater contaminants. By doing so, we can protect the health of communities, ensure the sustainability of water resources, and support the long-term success of industries that rely on them.
The study, published in Discover Environment, which translates to Discover Environment, provides a comprehensive overview of the health risks posed by fluoride and nitrate in the Vea catchment’s groundwater. It is a stark reminder of the importance of ongoing research and monitoring in the water, sanitation, and drainage industry. As Zango puts it, “The time to act is now. The health of our communities and the sustainability of our water resources depend on it.”
