In the present investigation, the study was carried out to know the present scenario of selected cities of the Marathwada Region in Maharashtra, India, related to wastewater quality. The spatial distribution analysis of wastewater collected from six cities (3 cities from Jalna district sampling sites Bhokardan, Partur, and Ambad and 3 cities from Chhatrapati Sambhajinagar [Aurangabad] district sampling sites Paithan, Gangapur, and Phulambri) was investigated. The result shows that the water conductivity of the wastewater ranged from 1625.36 to 2685.45 mS/cm, and its pH varied from 6.7 to 7.5. The biological oxygen requirement ranged from 56 to 1000 mg/L, while the maximum total dissolved solid was 1290 ppm. The dissolved oxygen level ranged from 0.04 to 0.25 mg/L, and the chemical oxygen requirement of the chosen sites varied greatly from 235.96 to 3577.6 mg/L. City-1 (Bhokardan) had the highest nitrate content (48.57 mg/L), whereas city-3 (Ambad) had the highest sulfate level (120.5 mg/L). It was discovered that city-2 (Partur) has a high phosphate level (83.80 mg/L). The physicochemical parameters examined in this paper differed throughout the cities, and each parameter was contrasted with the BIS Standards 1995 allowed limit. [ABSTRACT FROM AUTHOR] |
