ANALYSIS OF POLLUTION LEVEL OF SOIL AND WATER BODY IN GOKANA LOCAL GOVERNMENT AREA OF RIVERS STATE

Summary

The analysis of the pollution was carried out using some parameters on both samples (water and soil) to determine their level in terms of pH, electrical conductivity (E.C), dissolved oxygen (DO), biological oxygen demand (BOD5), sulphate, chromium, nitrate-nitrogen, phosphorous (P), phosphate (P205), copper ion, oil/Grease, etc in order to determine the extent of pollution. The results obtained from the polluted water analysis were pH (7.46), E.C. (123.33µs/cm), DO (7.4mg/L), sulphate
(31.66mg/L), chromium (0.22mg/L), copper (0.21mg/L), Iron (21.1mg/L), Nickel(0.02mg/l), BOD5 (6mg/L), nitrate-nitrogen (31.19mg/L), Phosphorous (3.35mg/L), oil/Grease (6.98mg/L), etc while results obtained from soil sample analysis for heavy metals concentration were pH (7.46), oil/Grease(69.58) and (22.13)%. The AAS result (parameters) from soil sample determined include
lead (ppm) 56.011, Iron (ppm) 68.191, copper (ppm) 0.897, chronuim (ppm) 1.092, etc for top soil (0- 15cm) while for the subsoil (15-30cm depth) lead (ppm) 57.011, Iron (ppm) 69.698, copper (ppm) 0.532, chromuim (ppm) 0.701, etc respectively. The values obtained from laboratory work were subsequently compared with WHO standard and it was found that the values were very much higher, thus indicating serious environmental degradation in terms of pollution of water and soil.
