Abstract

The objective of this research was
spatial characterization of the biological and physico chemistry of the surface
water, sediment and dredge 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 of monitoring stations.
ArcGIS 10.2 used for processing of locational data. Surface water outcomes at
the four stations with pH of 6.22 to 7.38. Conductivity values are from 62.0 to
78.0µS/cm and other sample parameters as shown in the table of results. The
Heavy metals 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. Ni recorded 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 <2.00 to 30.0MPN/100ml and <2.00 to 23.0MPN/100ml
respectively. Sediment and Dredge Spoil at five stations of pH values are from
5.40 to 6.97. Conductivity values are 170 to 306µS/cm while Salinity values
ranged from 0.048- 0.086ppt. Heavy metals and other results are as shown in
result tables. Based on the laboratory analyses results, impact on the
biological characteristics and physico chemistry of the environment is minimal. Monitoring the pollution of Water
(inland Rivers, lakes and streams) will ensure sustainable environmental
development. Combining environmental data with location data useful to
formulate decisions in terms physical planning for sustainable resource
management.
