PHYSICOCHEMICAL CHARACTERISTICS, HEAVY METAL CONCENTRATION, AND MICROBIAL CONTAMINATION IN KEY WATER SOURCES WITHIN BENUE SOUTH SENATORIAL DISTRICT, NIGERIA
Abstract
Access to clean and safe water is crucial for human health and well-being. This study aimed to assess the physicochemical characteristics, heavy metal concentration, and microbial contamination in key water sources within the Benue South Senatorial District, Nigeria. A total of nine water samples were collected from three river sources, including Ohimini, Okpokwu, and Ofumenyi rivers, across different locations within the senatorial district. The physicochemical parameters analyzed included pH, electrical conductivity (EC), total dissolved solids (TDS), turbidity, temperature, and dissolved oxygen (DO). In addition, heavy metal concentrations, including lead (Pb), cadmium (Cd), arsenic (As), and mercury (Hg), were determined using atomic absorption spectrometry. Microbial contamination was assessed by culture and antibiotic susceptibility. The results revealed considerable variations in the physicochemical characteristics of the water sources. The pH values ranged from acidic to slightly alkaline, whereas EC, TDS, and turbidity levels varied widely, indicating differences in water quality across the studied sites. The dissolved oxygen levels were generally within acceptable limits, indicating adequate aeration in the water sources. However, some samples exhibited elevated levels of heavy metal contamination, particularly lead, which exceeded the recommended guidelines for drinking water. This poses a significant health risk to communities relying on these water sources. Microbial analysis revealed widespread contamination of water sources with coliforms and E. coli, posing a risk of waterborne diseases, highlighting the need for improved treatment and sanitation practices in Benue South Senatorial District
