Locational Analysis of Surface Water Quality, Sediment and Dredge Spoil At Nembe, Bayelsa State-NIGERIA

The objective of this research was spatial characterization of the biological and physico chemistry of the surface water, sediment anddredge spoil samples from the Dredging activity at Obama creek in Bayelsa State. A total of nine (9) samples were collected, four (4)from surface water and the other four (4) from sediment samples from dredging station, 200m upstream/downstream and 500m-800m, away from the reference location and one (1) sample of dredge spoil. GPS receivers was used to capture coordinates ofmonitoring stations. ArcGIS 10.2 used for processing of locational data. Surface water outcomes at the four stations with pH of 6.22to 7.38. Conductivity values are from 62.0 to 78.0μS/cm and other sample parameters as shown in the table of results. The Heavymetals are Cd, Pb, and Cr, and had values from 0.011 to 0.026mg/l, 0.119-0.128mg/l, and 0.064 to 0.092mg/l respectively. Nirecorded values are from 0.061 to 0.072mg/l while Zn values are from 0.194 to 0.232mg/l. Total and Faecal Coliform ranged from
