Assessment of the physico-chemical quality of Uturu section of Aku river in southeastern Nigeria

The physicochemical monitoring of water quality is very key both to aquatic life and public health. To date little known about the downstream Aku river, located in Uturu, Isuikwato local government area Abia state. Therefore aim study determine river terms several parameters heavy metals analysis ascertain properties reveal pollution problems. Samples were collected at 15m, 30m, 45m, 60m, 75m, 90m 105m interval for seasons. Results shows that temperature, conductivity, hardness, salinity, Total Dissolve Solid (TDS), Suspended Solids (TSS), turbidity, pH, Oxygen (DO), chlorine, nitrate, lead, iron, arsenic, copper zinc, ranged: 24.190C-26.500C, 165.18-275.46μs/cm, 100.26-139.11mg/L, 520.15-815.24ppt, 380.52-710.08mg/L, 15.12-30.68mg/L, 0.32-1.73NTU, 6.6-7.9, 6.21-11.63mg/L, 1.14-3.30mg/L, 65.01-128.05mg/L, 35.53-58.00mg/L, 0.0002-0.007ppm, 0.02-0.15ppm, 0.002-0.006ppm, 0.44-1.03ppm 0.1-0.27ppm respectively. presence TDS, TSS, turbidity nitrate above World Health Organization (WHO) tolerance limits, confirmed contaminants body, hence not suitable drinking thus poses a potential threat life.
