Dynamics and Impact of Insitu Bitumen Seeps on Soil and Groundwater Resources

Retrieved sediment samples from the 15 m deep boreholes (A, B and C) were subjected to grain-size analysis. Gas Chromatography-Mass Spectroscopy (GCMS) analysis of selected sediment and water samples from the boreholes and adjoining swamp delineated the presence, types and concentration of polycyclic aromatic hydrocarbons (PAHs). The sediments were retrieved as ditch-cuttings at 1 m intervals during the borehole construction.
Pumping test data retrieved from pumping at each of the 3 boreholes for a maximum of 6 hours each, were analysed using the Neuman solution (Nueman, 1975) for an unconfined aquifer system to determine the hydraulic parameter of the aquifer.
