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

摘要

The objective of this research wasspatial characterization of the biological and physico chemistry of the surfacewater, sediment and dredge spoil samples from the Dredging activity at Obamacreek in Bayelsa State. A total of nine (9) samples were collected, four (4) fromsurface water and the other four (4) from sediment samples from dredgingstation, 200m upstream/downstream and 500m-800m, away from the referencelocation ?and one (1) sample of dredgespoil. GPS receivers was used to capture coordinates of monitoring stations.ArcGIS 10.2 used for processing of locational data. Surface water outcomes atthe four stations with pH of 6.22 to 7.38. Conductivity values are from 62.0 to78.0μS/cm and other sample parameters as shown in the table of results. TheHeavy 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 arefrom 0.061 to 0.072mg/l while Zn values are from 0.194 to 0.232mg/l. Total andFaecal Coliform ranged from <2.00 to 30.0MPN/100ml and <2.00 to 23.0MPN/100mlrespectively. Sediment and Dredge Spoil at five stations of pH values are from5.40 to 6.97. Conductivity values are 170 to 306μS/cm while Salinity valuesranged from 0.048- 0.086ppt. Heavy metals and other results are as shown inresult tables. Based on the laboratory analyses results, impact on thebiological characteristics and physico chemistry of the environment is minimal. Monitoring the pollution of Water(inland Rivers, lakes and streams) will ensure sustainable environmentaldevelopment. Combining environmental data with location data useful toformulate decisions in terms physical planning for sustainable resourcemanagement.
