The present study investigates the physicochemical and microbial characteristics of distillery effluents collected from the industrial region of Chhatrapati Sambhajinagar (formerly Aurangabad), Maharashtra, India. Ten effluent samples were analyzed to assess key environmental parameters, including pH, electrical conductivity (EC), dissolved oxygen (DO), chemical oxygen demand (COD), biological oxygen demand (BOD), total solids (TS), total dissolved solids (TDS), total suspended solids (TSS), nutrients (total phosphorus and total nitrogen), heavy metals (Cd, Cr, Ni, Pb, Zn, Fe), and total viable count (TVC). The results revealed that all measured parameters significantly exceeded the permissible limits set by the Central Pollution Control Board (CPCB), World Health Organization (WHO), and American Public Health Association (APHA), indicating high levels of organic and inorganic pollution. The effluents were acidic (pH ~5.0), dark in color, and rich in recalcitrant organics and heavy metals, with exceptionally high COD (up to 27,303 mg/L), BOD (14,984 mg/L), and microbial loads (up to 1.0 × 10? CFU/mL). The findings highlight the environmental threat posed by untreated or inadequately treated distillery wastewater in the region. This study underscores the urgent need for advanced effluent treatment strategies, particularly microbial bioremediation, to mitigate pollution and ensure environmental compliance for sustainable industrial practices.
