Abstract

The qualitative evaluation and hydrogeochemical attributes of groundwater in Owerri Capital Territory Owerri was investigated to assess the quality for human consumption and agricultural purposes. A total of sixteen (16) groundwater samples were collected and analyzed for physicochemical and biological properties. The range of temperature (oC), colour (Hz), and turbidity of groundwater in the study area are between: 20-28.3, 5-15, and 1-50 respectively. The average of pH , conductivity (us/cm),TDS (mg/l), and hardness (mg/l) are: 7.66, 0.135, 34.64, and 7.94 respectively. The result also reveals that the concentration of Na+(mg/l), K+(mg/l), Ca2+(mg/l), Mg2+(mg/l), Fe+(mg/l), Pb2+(mg/l),Cd2+(mg/l), Cu+(mg/l),and Zn2+ (mg/l) range between: 3.33-7.6, 0.2-6.8, 2.4-8.3,1.02-3.44, 0.001-0.59, 0.001-0.01, 0-0.16, 0.06-2.88 and 0.01-2.18 respectively. Water Classification result of the groundwater samples show the predominance of alkali bicarbonate water type (Na+ + K+) - HCO3- that is largely soft and therefore, mostly of acceptable quality for household uses. Sodium Absorption Ratio (SAR) of the groundwater samples in the study area showed that the samples fall below 1.4meq/l, indicating predominance of excellent water for irrigation purposes in accordance with recommended standard. This study recommends among other things that groundwater resources development in the area requires elaborate qualitative assessment, to ensure that any necessary pre-use treatment is effected.
