Water is an essential component of human living and crucial in metabolism, substrate transport across membranes, cellular homeostasis, temperature regulation, and circulatory function. Access to quality water is a critical concern of any society. However, water shortage remains the central problem of many households across the universe, prompting people to depend on water sources that are considered unhealthy for human consumption. The primary purpose of this study was to examine the bacteriological compositions of water sources in Kogi State based on seasonal disparities. Water samples were obtained from streams and hand-dug wells within the Ankpa and Obajana areas during the rainy and dry seasons. The analysis conducted on the samples revealed that the water sources were heavily contaminated with bacteria at both seasons.
