Physico-chemical Assessment of Agbabu Water, Oluwa River, Odigbo Local Government Area, Ondo State, Nigeria
This study assesses the physico-chemical properties of Agbabu Water in Oluwa River, Nigeria, highlighting pollution impacts from bitumen and waste, and providing vital baseline data for environmental management
Abstract
Agbabu Water, Oluwa River, serves artisanal fishing, ferrying, and domestic purposes in Odigbo Local Government Area (OLGA), Ondo State, Nigeria. The river is subjected to bitumen spills and the discharge of domestic and agricultural wastes, which may negatively affect water quality and aquatic biota. Despite increasing anthropogenic pressures, limited studies have examined the river’s limnology and biodiversity. Extensive bitumen spillage and uncontrolled waste discharge have pollution implications, altering the ecological balance and destroying aquatic habitats. This study aimed to investigate the physico-chemical parameters of Agbabu Water to provide baseline data for effective environmental management. Monthly surface water samples were collected from the Oluwa River over six months (June 2024 to November 2024). Physico-chemical parameters were analysed using standard procedures as outlined by the American Public Health Association (APHA, 2005). Results revealed temperature values between 26.0–32.0°C; transparency (1.0–8.0 m); alkalinity (14.0–25.0 mg/L); electrical conductivity (18–105 µS/cm); dissolved oxygen (1.2–3.8 mg/L); sulphate (0.0–4.0 mg/L); and total dissolved solids (18–36 mg/L). The downstream station (Station A) recorded the highest values for most parameters. However, no statistically significant differences (p < .05) were observed across stations. All measured parameters were within the acceptable limits for drinking and aquatic life as prescribed by national and international standards. It is recommended that regular monitoring and enforcement be undertaken by relevant government agencies, public health authorities, and local leaders.
