Assessment of Groundwater Quality in Coal Mining and Non-Mining Areas of Dhanbad

This study presents a comparative assessment of environmental quality in coal mining and non-coal mining areas of Dhanbad, Jharkhand. The investigation was conducted in the mining region of Jharia Coalfield and the residential area of Saraidhela. The objective of the study was to evaluate and compare air and water quality parameters in both locations. Air quality assessment included monitoring of PM2.5, PM10, SO₂, NOx, and Air Quality Index (AQI). Higher concentrations of particulate matter were observed in the coal mining area due to drilling, blasting, coal transportation, and overburden dumping activities. Water quality analysis was also conducted to assess the impact of mining activities on groundwater. Parameters such as pH, Total Dissolved Solids (TDS), hardness, iron concentration, and turbidity were evaluated. The mining area showed comparatively higher iron content and variation in pH, indicating possible influence of acid mine drainage and surface runoff from mining operations. The residential area exhibited relatively stable water quality parameters within acceptable limits. The study highlights significant environmental differences between coal mining and non-mining areas and emphasizes the need for effective pollution control and sustainable environmental management practices in mining regions.
