Risk Assessment of Water Quality in Public Institutions in Warri, Delta State

This study aimed to evaluate the risks associated with water quality in public institutions in Warri, Delta State. Water samples were collected from five public institutions namely, School, Hospital, Mall, Church and Hotel. Physico-chemical and microbial analyses were conducted using standard methods. The water quality index (WQI) and risk assessment matrix (RAM) were applied the quality and potential risks. Results revealed slightly acidic pH levels (5.1-6.63) in water samples. Dissolved oxygen levels (3.8-4.2 mg/L) were below WHO recommendations.

Water Quality Profile of Ekenwan River and Antibiotics Sensitivity Pattern of Its Isolated Bacteria

This study was aimed at evaluating the water quality profile of Ekenwan River located in Edo-South, Nigeria and also to determine the antibiotics sensitivity pattern of its isolated bacteria. Water samples were collected from upstream and downstream stations of the river and they were designated as station A and station B respectively; standard analytical and bacteriological procedures were adopted. The pH of water samples for station A ranged from 5.11-5.86 while and station B ranged from 4.11-5.94.
