Abstract:
The assessment of physico-chemical and bacteriological quality of groundwater around Obosi
open waste dump in South-eastern Nigeria was investigated. Four leachate and 24groundwater
samples from 8 concentric study cells centered at the waste dumpsite were collected and
analyzed using experimental method. The heavy metals were determined using Atomic
Absorption Spectrophotometer (AAS). The results obtained revealed the mean concentrations of
pH(5.73±0.07), electrical conductivity(163.41±2.99)µS/cm, DO(7.93±0.57),
As(0.01±0.004)mg/L, lead(0.48±0.06)mg/L, iron(0.55±0.17)mg/L and mercury(0.71±0.11)mg/L.
The presence of microorganisms in some of the water samples within the vicinity of the waste
dump indicates groundwater contamination and shows that the leachate generated from the waste
dump site could have contaminant risks on boreholes located proximal to the waste dump. It was
recommended that a contaminant migration mitigation measure should be performed to reduce
the risk of groundwater contamination in the study area |
