“…In dry weather, long-range atmospheric deposition (Barandovski et al, 2015) accounts for PTE dispersal into open SHDWs (Fig. 2b) through the prevailing easterly winds (Kanda et al, 2019). High concentrations of SO 4 2− , Cl − , Cd and Fe were recorded at relatively shallow wells.…”

Groundwater from shallow hand-dug wells at an abandoned gold mine tailings dam was characterised for selected physicochemical parameters during dry and wet seasons of 2018 and 2019. Health risk exposure of the local population (adults and children) through ingestion and dermal exposure was assessed. Groundwater quality parameters were lower than international drinking water quality guidelines (p < 0.05). The parameters were significantly influenced by season of the year (As, Cl−, SO42−), nature (As, Cd, Cl−, Fe, NO3−, SO42−), depth (Cd, Cl−, Fe, Ni, SO42−) and direction of the well (Cu, Cl−, Fe, NO3−, Pb, SO42−) (p < 0.05) relative to the tailings dam. Groundwater did not pose non-carcinogenic risk due to studied trace elements. However, arsenic had the potential to cause medium to high cancer risk to the local population. We propose re-vegetation of the tailings dam, diversion of surface tailings drainage to a containment pond and the provision of continuous piped water supplies.

“…Ref. [39] did a study in Zimbabwe on abandoned goldmines, regarding the surrounding soil of a tailings dam, and found that a low pH (acidity), electrical conductivity, potentially toxic elements (PTEs), and sulphate in the soil holds a threat to communities and the environment. To safeguard the environmental integrity and public health, they suggest stricter legislation, environmental stewardship, and environmental impact assessments.…”

Goldmining contributes substantially to the Gross Domestic Product (GDP) of the Zimbabwean economy through revenue generated from exports, however it also incurred numerous challenges to the environment. Amongst others, these challenges embody ecological degradation; water and air pollution; and depletion of natural resources. In this paper, we establish the effects of mining operations on the environment through a comprehensive literature review, and how the integration of environmental management accounting practices (EMAPs) such as material flow cost accounting (MFCA), life cycle costing (LCC), and activity-based costing (ABC) could be integrated into a conceptual framework to address environmental challenges. EMAPs were chosen as they generate both physical and monetary data, which could promote transparency in material usage within the goldmining sector. Our analyses revealed a substantial body of literature on separate and individual EMAPs, yet very little was found on the integration of EMAPs. The main contribution of this work is the development of an integrated conceptual EMAPs framework on the strength of sets of qualitative propositions, aimed at promoting green goldmining for Zimbabwe as a developing economy. Future work would involve the validation of the framework among key stakeholders in the Zimbabwean goldmining industry.
