The study was carried out to evaluate the environmental impact of waste dumpsite to the quality of ground water as a major component of the environment using Idunmwowina Community as a case study. A total of fifteen (15) samples of borehole water were collected or sampled at 15 different locations. All samples were subjected to heavy metal determination, physiochemical parameters and bacteriological analysis. The water samples were analyzed to determine its portability and also compared with WHO and NAFDAC standard. The diluent was analyzed using AAS (Atomic Absorption Spectrophotometer). The physiochemical analysis indicated minimum and maximum value range pH (5.1 to 6.8, EC (19.0μs/cm to 167.2μs/cm) Clear Turbidity, Salinity (0.019mg/l to 1.00mg/l), TDS (10.45mg/l to 91.6mg/l) Nitrate (0.730mg/l to 2.408mg/l) Bicarbonate (0.41mg/l to 0.49mg/l) Alkalinity (41.00mg/l to 50.00 mg/l) Sulphate (3.102mg/l to 3.471mg/l) DO (2.11 to 2.46) BOD (2.44mg/l to 3.00mg/l) COD (5.31 to 6.48) and Ammonium Nitrogen (0.13mg/l to 2.11mg/l). The analysis for heavy metal shows Lb (0.01-0.03mg/l), Cd (0.01 mg/l), Ni (Not Detected), Cr (0.06-0.28 mg/l), Fe (0.1 mg/l), Zn (0.01-9.17 mg/l) These values obtained all fall below WHO standard. The quality of samples obtained were seriously compromised as a result of feacal bacteria growth and elevated values of heavy metals such as lead (Pb), cadmium (Cd) and chromium (Cr) in soil and groundwater.
