Sanitation and Water Quality in Port Harcourt Waterfront Settlements

Abstract

Sanitation and water quality are a good measure to judge the living standard and health status of a community. This study focused on the assessment of surface and ground water resources from selected waterfront areas within Port Harcourt metropolis notable for their poor sanitary conditions as receptacles for domestic wastes. Surface water (river) and ground water samples were collected from Abuloma waterfront, Marine Base and Afikpo (Diobu) and their microbiological and physiochemical parameters determined using standard laboratory methods. The microbiological parameters analyzed include total heterotrophic bacteria count (THBC), fecal coliform count, total coliform count, Salmonella count, Shigella count and Vibrio count. The physiochemical parameters monitored include pH, temperature, conductivity, salinity total dissolved solids (TDS), dissolved oxygen (DO), turbidity and biological oxygen demand (BOD). The THBC ranged from 15x101cfu/ml to 1.3x102 cfu/ml; total coliform count ranged from 0 to 17cfu/ml; all the samples had no fecal coliform; the Salmonella count ranged from 0 to 15 cfu/ml; the Shigella count ranged from 0 to 30cfu/ml and Vibrio count ranged from 0 to 15 cfu/ml. The pH values ranged from 5.9-7.6; temperature from 27.5°C to 29.6°C; salinity from 0.012 mg/l to 0.379 mg/l; conductivity from 17.8 s/cm to 19370 s/cm; TDS from 12.3 mg/l to 13610 mg/l; DO from 2.41 mg/l -3.4mg/l, turbidity from 0.24 NTU to 1.11 NTU and BOD from 16 mg/l to 120 mg/l. The results obtained showed that the water resources are not safe and pose risk to human health. These findings highlight the need to improve the sanitary condition of waterfront areas and promote water treatment to ensure the health and safety of the public.
