The Vea catchment, especially in the Bongo area, is among the first areas in Ghana where high fluoride levels in groundwater were reported leading to extensive hydrochemistry studies within the catchment. Although high fluoride (F\u2212) levels
\nin groundwater are known to be one of the causes of waterborne diseases and have been studied extensively across the
\nglobe, the health risk of the established high levels of F\u2212 in the catchment and its spatial distribution is still an enigma.
\nFor the above reasons, F\u2212 and NO3
\n\u2212 health risks assessment and spatial characterization were conducted in this study
\nusing indexical proxies and ArcGIS. The multilinear regress modeling at \u03c1<0.05, has Ca2+, TDS, HCO3
\n\u2212, and NO3
\n\u2212 as the
\ncontrollers of F\u2212 while that of NO3
\n\u2212 are Ca2+ and Mg2+. From the concentration levels classification of F\u2212, 10% and 57.1%
\nof the area are prone to dental caries and skeletal fluorosis, respectively, while 65.7% of the area is at F\u2212 risk from the
\nfluoride risk index (FRI) classification. The hazard quotient (HQ) values>1 for F\u2212 are 68.6% and 57.1%, while that for NO3
\n\u2212 is
\n11.4% and 4.3% for children and adults, respectively. The Vea catchment has a very high hazard index (HI) value of 95.7%
\nand 82.9% for children and adults in the area. The carcinogenic risk (CR) of NO3
\n\u2212 in the area is 75.7% for children and
\n87.1% for adults. From the percentages of the HI values, there is a need for urgent action toward providing fluoride-free
\ndrinking water to the people within the catchment by targeting uncontaminated aquifers for safe groundwater supply
\nwithin the catchment while ensuring continuous monitoring of current boreholes.<\/p>\n
