Assessment of the Impact of Marble Waste on Ground Water Quality Parameters

Abstract

Marble waste, a byproduct of extensive mining and processing activities, poses significant environmental challenges, particularly concerning groundwater contamination. This study assesses the impact of marble waste on groundwater quality parameters in areas with significant marble processing activities. Groundwater samples were collected from various sites, including those near marble waste disposal areas and control sites, and analyzed for key physicochemical parameters such as pH, turbidity, total dissolved solids (TDS), and heavy metals (lead, cadmium, chromium). The results revealed substantial deviations in groundwater quality in areas near marble waste disposal sites compared to control locations. Elevated pH levels, high TDS, and increased turbidity were observed, alongside heavy metal concentrations that exceeded permissible limits set by international standards. Seasonal analysis indicated contamination peaks during the dry season due to reduced dilution capacity. Correlation analysis highlighted strong relationships between turbidity and heavy metal concentrations, suggesting that particulate matter facilitates the transport of contaminants. This study underscores the urgent need for sustainable waste management practices to mitigate the environmental impacts of marble waste. Recommendations include recycling marble waste, implementing advanced waste treatment technologies, and enforcing stricter regulatory measures. These findings provide critical insights for policymakers and stakeholders, emphasizing the importance of preserving groundwater quality for environmental sustainability and public health.
