In this study, we investigated the impact of quarrying as an environmental ethical crisis. The need for the study arose when we realised the deteriorating effect of the quality of life in our community, which is located next to a limestone quarry. To obtain a deeper understanding of the adverse impact on the environment and the quality of life of …

Acid mine drainage (AMD) continues to be a concern in coal mining because it reduces surface water and groundwater quality (Verburg et al., 2009) and may perhaps persist for several years. In the U.S. only, AMD pollutes over 20,000 km of streams (Skousen et al., 2019). Blasting and dewatering exposes sulfide minerals, posing threats …

3.4.2 Impacts on Groundwater. Limestone mining is likely to result in relatively local impacts such as reduced water quality, rerouting of recharge water in aquifer, increased run-off and thereby leading to localized reduction in groundwater storage (Hobbs and Gunn 1998 ).

Why is Mining Limestone Bad for the Environment? Limestone mining isn't discussed as often as, say, fracking or oil drilling, but it has its fair share of risks and problems. Let's look at six top limestone mining issues. 1. Groundwater Contamination. Limestone is mined underground, but vital groundwater is located underground too.
