Abstract
Unregulated mining drives considerable long-term soil and water pollution with increased health risks to humans and other organisms. The main objective of this study is to assess the water quality, physicochemical parameters, heavy metal content, and health risks of borehole water from selected mining communities in Ghana. Quality parameters of 56 borehole water samples collected from 19 mining communities in the Amansie West District, Ghana were carried out. The study is one of the few studies to be carried out in the district because of its breadth of communities, depth of analysis, and scale of health risk assessments performed. Physicochemical parameters including pH, conductivity, turbidity, total dissolved solids, and color were evaluated using standard and appropriate methods. Additionally, arsenic, cadmium, lead, and mercury were evaluated using an atomic absorption spectrometer. Observed mean physicochemical parameters varied from 5.1 to 6.5 pH, 59.3 to 325 μS/cm conductivity, 1.4 to 86.4 NTU turbidity, 32.5–214 mg/L total dissolved solids, and 2.5–250 Hz color. Also, the mean concentration of the heavy metals varied from 1.6 ± 2.24 to 169.14 ± 2.18 μg/L arsenic, 0.6 ± 2.24 to 6.0 ± 0.71 μg/L cadmium, 1.25 ± 2.00 to 15.60 ± 1.11 μg/L lead and 0.025 ± 2.00 to 3.33 ± 0.17 μg/L mercury. There was no statistically significant link between arsenic, cadmium, lead, and mercury at 0.05 concentrations predicting source diversities. Though some samples met WHO quality standards, others were unsafe with increased health risks due to color, turbidity, acidity, and high arsenic issues. In conclusion, this study observed an increased health risk in some selected sampled communities due to exposure to mining-influenced contaminations from heavy metals and particulate matter. This implies that without urgent mining waste disposal regulations, scarcity of quality water and increased risk to health issues could be imminent.
期刊介绍:
Groundwater for Sustainable Development is directed to different stakeholders and professionals, including government and non-governmental organizations, international funding agencies, universities, public water institutions, public health and other public/private sector professionals, and other relevant institutions. It is aimed at professionals, academics and students in the fields of disciplines such as: groundwater and its connection to surface hydrology and environment, soil sciences, engineering, ecology, microbiology, atmospheric sciences, analytical chemistry, hydro-engineering, water technology, environmental ethics, economics, public health, policy, as well as social sciences, legal disciplines, or any other area connected with water issues. The objectives of this journal are to facilitate: • The improvement of effective and sustainable management of water resources across the globe. • The improvement of human access to groundwater resources in adequate quantity and good quality. • The meeting of the increasing demand for drinking and irrigation water needed for food security to contribute to a social and economically sound human development. • The creation of a global inter- and multidisciplinary platform and forum to improve our understanding of groundwater resources and to advocate their effective and sustainable management and protection against contamination. • Interdisciplinary information exchange and to stimulate scientific research in the fields of groundwater related sciences and social and health sciences required to achieve the United Nations Millennium Development Goals for sustainable development.
