Tar sands or oil sands are sandstones that contain petroleum products that are highly viscous like tar and thus cannot be drilled and pumped out of the ground readily like conventional oil This unconventional fossil fuel is bitumen which can be pumped as a fluid only at very low recovery rates and only when heated or mixed with solvents
— Monitoring the extent of heavy metal remediation on reactive materials employed in remediation schemes relies on downflow concentration sampling The latter implies that a decreasing barrier remediation efficiency only becomes apparent once a contaminant breakthrough has occurred and thus contamination past the barrier Spectral
