Locational Analysis of Surface Water Quality, Sediment and Dredge Spoil At Nembe, Bayelsa State-NIGERIA
Journal Title: International Journal of Environment and Geoinformatics - Year 2019, Vol 6, Issue 1
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.
