Physicochemical and heavy metals analysis of Udo Awankwo River in Ikot Ekpene, South-South, Nigeria

The physicochemical and heavy metal studies of water samples obtained from Udo Anwankwo River were investigated. Water samples were collected from three different sampling points along the course of the river and analyzed using standard procedures. The physicochemical parameters like the Biochemical Oxygen Demand (BOD) were above the less than 4.0mg/l permissible limit by WHO. The temperature ranged from 28.0°C. to 28.2°C while the pH and electrical conductivity ranged from 7.70 to 8.03 and 16.25to 33.16 µs/cm. All the heavy metals (Nickel, Lead, Cadmium, Chromium and Arsenic) analyzed were above the permissible limit’s standard set by WHO for drinking water. The study suggests the need for urgent measures towards the control of pollution and enlightening of the locals on the need for proper disposal of wastes and water treatment before use.
