Tertiary institutions, which provide education and temporary housing for thousands of students, face environmental challenges. This study analyzed water samples from five hostels for microbiological contamination and physicochemical parameters. Bacterial counts ranged from 2 × 10¹ to 1.3 × 10³ CFU/ml, with no coliform or E. coli detected. Proteus was found in samples 1 and 2, while Pseudomonas was present in samples 3 and 4. The analysis revealed acidic pH values between 4.77 and 5.33 and low total dissolved solids (TDS) from 13 to 37 mg/l. Iron concentrations were the highest, ranging from 62.32 to 154.70 mg/kg. Manganese peaked in sample 3 (0 to 15 cm depth) with 34.46 mg/kg. Lead levels ranged from 1.25 to 3.09 mg/kg, and copper levels varied from 4.36 to 11.05 mg/kg. Cadmium levels were stable at 0.01 to 0.02 mg/kg, while arsenic and mercury were not detected. Waste characterization showed that plastics and food constitute a significant portion of hostel waste. Regular monitoring of water quality and maintenance of storage systems can enhance drinking water in student hostels. Improving waste disposal and implementing better waste segregation are also essential to minimize metal accumulation. These actions will significantly enhance waste management and drinking water quality.
