"Randle Reef is a nearshore area located in the southern portion of Hamilton Harbour and contains the most contaminated sediment within the harbour. Sediment contamination at Randle Reef, particularly with polycyclic aromatic hydrocarbons (PAHs), has been a concern for decades. Historical industrial discharges created the contaminated sediment site which contains a high concentration of coal tar. There have been at least 6 sediment sampling events at Randle Reef, spanning over 25 years. This has included grab sampling, gravity coring, and borehole coring. The sampling events and the concentrations of PAHs measured are described. The precise extent of sediment contamination at Randle Reef is not fully known. Enough information has been obtained, however, to define the most severely contaminated sediment in the vicinity of Randle Reef, within an area of about 10 ha"--Abstract.
