    ABSTRACT Water quality assessment is crucial in ensuring the safety and health of individuals, especially in residential areas like student hostels. This study assessed the physicochemical parameters, hygiene performance, and bacteriological quality of stored water in hostels in Malete, Nigeria. Twenty different water samples were collected and analyzed for key physicochemical properties and hygiene practices related to water storage and handling. Membrane filtration technique was employed for the bacteriological estimation and identification of the isolates were carried out using standard methods. Hygiene performance indices ranged from 40 - 80 % of the stored water samples. The findings revealed varying levels of physicochemical properties; Temperature oscillated from (26.0 - 28.4 °C), TDS (48.0 – 690.0 mg/L), pH (5.44 -7.61), EC in μS/cm (96.0 – 689.0), salinity (0.0 -0.01%) and resistivity (1.170 – 4.910 MΩ/cm). Total Bacterial Count ranged from 80.0 ±0.5.77 - 200±20.0 CFU/100ml, Total Coliform Count (0.0 - 100±10.00 CFU/100ml), Total Faecal Coliform Count (0.0 – 10.0±0.0 CFU/100ml), Total Salmonella- Shigella (0.0 - 100±26.45 CFU/100ml) and Total Pseudomonad Count (0.0 - 100±20.00 CFU/100ml). Poor hygiene practices, such as inadequate container cleaning and direct hand contact, contributed to bacterial contamination. The presence of coliforms in almost all the samples indicated potential health risks. This study highlights the need for improved water management practices and regular monitoring to ensure safe drinking water for hostel residents in Malete, Kwara State. Implementing proper hygiene education and water treatment methods is recommended.

    This study evaluated the quality of sachet and bottled water sold in Ilorin, Nigeria. Water samples were procured from selling points, and their physicochemical and bacteriological quality was assessed using standard methods. The results showed that the respective physicochemical parameters for sachet and bottle waters: temperature (26.6 °C and 23.9 °C), electrical conductivity (142.0 μs/cm and 111.0 μs/cm), total dissolved solids (68.5 mg/L and 58.0 mg/L), pH (7.5 and 7.3), and salinity (0.05 and BDL) of both sachet and bottled water samples respectively were within the permissible range recommended by the World Health Organization (WHO). Bacteriological analysis revealed that total heterotrophic bacterial counts (52.5*Z ± 4.7 and 35.0Z ± 0.9) for sachet and bottled water samples were within WHO limits; however, total coliform counts (51.50*Z ± 2.6 and 33.5Z ± 1.5) exceeded the acceptable range of 0 CFU/mL. Seven bacterial isolates identified were Pseudomonas aeruginosa, Klebsiella spp., Proteus spp., Enterobacter spp., Salmonella spp., Shigella spp. and Bacillus subtilis. The number of bacterial isolates in bottled water was higher, with Klebsiella spp. being the most prevalent. The findings suggest varying degrees of microbiological contamination, indicating that some packaged water samples are not of the highest quality. These results highlight the need for stricter monitoring and quality control measures to ensure the safety of packaged water

    Purpose: To investigate the impact of chitosan-silver nanoparticles (chitosan-AgNP) composite-treated water on some biochemical parameters in the albino rats. Methods: Water samples were pretreated with chitosan-coated silver nanoparticles (chitosan-AgNPs) prior to oral administration in a rodent model. Following a 28-day experimental period, serum biochemical markers associated with hepatic and renal functions and enzymatic activities were quantitatively assessed to evaluate potential physiological and metabolic alterations. Results: Biochemical analysis revealed significant alterations in liver and kidney function markers in rats exposed to contaminated water. Liver alkaline phosphatase (ALP), aspartate aminotransferase (AST), and γ-glytamyl transferase (GGT) activities were significantly decreased (p < 0.05), while serum ALP, AST and GGT levels were significantly elevated (p < 0.05) in the contaminated water group compared to control. Serum urea and creatinine levels were significantly higher in rats exposed to contaminated water (90 ± 0.08 mg/dL and 21.73 ± 4.03 mg/dL, respectively) compared to the control group (43 ± 0.13 mg/dL and 16.37 ± 1.97 mg/dL, respectively; p < 0.05). Conversely, administration of chitosan-AgNP-treated water significantly reduced these elevations, bringing the values closer to control levels. Bacteriological analysis showed a drastic reduction in total coliform and fecal counts from 1.44 × 10⁷ CFU/mL and 7.2 × 10⁶ CFU/mL, respectively, to 0 CFU/mL after 27 days of chitosan-AgNP treatment. Conclusion: The findings suggest that chitosan-AgNP treatment significantly reduces bacterial load in water and positively affects selected biochemical parameters of albino rats, indicating its potential as a water treatment option.
