Abstract
The accumulation and toxic effects of nutrient build- ups have caused many ecological damages to the aquatic ecosystem. In this study, concentration of many inorganic nutrients and their effects on the physicochemical parameters of water were determined in the underground water at four oil locations in Izombe axis, Imo state, with non-oil spill area as the control. Samples of the underground water were collected with Nansen and hydrobios water samplers and transported to the laboratory for analysis, except some parameters that were analyzed in-situ. The results showed the presence of most of the inorganic nutrients analyzed in quantities above the admissible levels (control), while the results of most physicochemical parameters were within the admissible levels (control), with certain exceptions recorded above the admissible levels in some of the locations. This therefore, calls for restraint in some of the human activities within the underground water locations, especially in the areas connected with oil exploration in locations 1 and 3. This result showed that location 2 (new camp site) was of better quality in terms of the physical and chemical parameters evaluated as well as the level of nutrients in the affected sites, based on the control data supplied.
