Abstract
The contamination of drinking and irrigation groundwater by the Sasti coal mines presents significant environmental and health challenges. This study assesses groundwater quality around the Sasti coal mines by collecting samples from 20 sites within a 10 km radius, analyzed across three seasons (pre-monsoon, monsoon, post-monsoon). Parameters measured include pH, electrical conductivity (EC), total dissolved solids (TDS), heavy metals (As, Pb, Cd, Hg), sulfates, nitrates, fluoride, and microbiological contaminants (total coliforms, E. coli). Results reveal that several sites exceed WHO limits for safe drinking water, with elevated levels of heavy metals, sulfates, and nitrates. Health risk assessments indicate significant non-carcinogenic and carcinogenic risks, corroborated by community health surveys showing higher prevalence of gastrointestinal and skin disorders. Soil and crop analysis reveal elevated heavy metal levels, posing risks to food safety and agricultural productivity. Proposed mitigation strategies include constructed wetlands, permeable reactive barriers, and phytoremediation. Improved mine waste management, regular groundwater monitoring, and AMD treatment systems are recommended. Policy measures focusing on stricter regulations, community awareness, and sustainable water practices are essential. GIS-based maps indicate contamination hotspots, aiding targeted mitigation. This study emphasizes the need for immediate remedial actions and sustainable groundwater management to protect public health and agriculture in the Sasti coal mines area.
