Assessing the Effects of Quarry Mining on Environmental Quality in Kalengwa Ward of Mufumbwe District

This study assessed the environmental effects of quarry mining in Kalengwa Ward, Mufumbwe District. Using a mixed methods approach, the research combined quantitative environmental measurements, air quality, water quality, and noise levels, with socio economic surveys and interviews. A sample of 100 respondents was drawn from a target population of 500 using Yamane’s formula. Findings revealed severe environmental degradation, including elevated dust concentrations (PM10 and PM2.5 far exceeding WHO and ZEMA limits), excessive noise levels (up to 92 dB), and localized water quality anomalies such as high magnesium and selenium concentrations and petroleum hydrocarbon contamination in one borehole. Land degradation and biodiversity loss were evident around quarry sites. Weak enforcement of environmental regulations exacerbated negative effects. The study concludes that quarry mining in Kalengwa offers short term economic gains but poses significant risks to sustainable development. Recommendations include stricter policy enforcement, dust and noise control measures, water protection strategies, community based restoration programs, and adoption of sustainable quarrying practices to balance development with environmental and social well being.
