ABSTRACT: The work of the paper focused
on the post impact of oil spill contamination of groundwater in Bassambiri
Nembe Bayelsa State. Groundwater samples were sampled from hand dug wells from
eight stations including the control point for physico-chemical investigation
using sterilized glass bottles. Sampling was carried out upstream and
downstream on the Santa Barbara River across the stations and the results are as follows surface water pH ranged 6.90 - 7.50,
electrical conductivity 19739.41 μS/cm - 28920.64 μS/cm and Chloride 6019.63 -
9274.82 mg/l. The Total Dissolved Solids (TDS) varied from 10472.72 mg/l - 16538.19 mg/l dissolved oxygen (DO) 6.21 mg/l - 7.371
mg/l while the mean biochemical oxygen demand (BOD) 0.09 ± 0.52 mg/l - 2.4 ±
0.81 mg/l, temperature 28.04℃ - 31.79℃ while total alkalinity is 43.95 mg/L
-73.87 mg/L. Calcium ion ranged 375.68 mg/l - 536.72 mg/l, Magnesium ion 88.35
- 243.24 mg/l and Potassium ion 41.27 - 121.17 mg/l. The results of the study
showed that the pH, salinity, alkalinity,
total suspended solids (TSS), Chlorides, Phosphates, and Nitrates are
within permissible limits of the WHO, however the electrical conductivity, TDS, turbidity, DO, BOD, and hardness exceeded
WHO permissible limits for drinking water. Total Petroleum Hydrocarbon (TPH)
and Heavy metals had low concentrations in the Santa Barbara River across the study area suggesting that surface water is not polluted. However, the surfactants used
initially to contain the oil pollution were effective based on this research.
