Apr 01, 2000· At the opposite extreme to changes in pressure and flow, stagnation was also found to result in PAH contamination. When anaerobic water was kept in the same section of tar-lined pipe for seven hours, PAH levels were seen to increase. After a two-day period a total PAH level of 0.135mg/l was reached, way in excess of acceptable limits.

Coal tar is a byproduct of the coking, liquefaction or gasification of coal. Coal-tar pitch is the residue that remains after the distillation of coal tar, that is, the thick black liquid remaining after various oils are removed from coal tar for use in the manufacture of industrial and consumer products. Coal-tar pitch is separated, or "refined", into 12 grades of viscosity.
