Zonation of contaminated bottom sediments in Hamilton Harbour as defined by statistical classification techniques / D.J. Poulton, W.A. Morris, and J.P. Coakley. : En13-5/95-04E-PDF

"Hamilton Harbour is one of 43 Areas of Concern on the Great Lakes designated by the International Joint Commission (IJC) as having significant environmental degradation. Problems identified by the joint Environment Canada - Ontario Ministry of Environment and Energy working group include loss of fisheries and wildlife habitat, restrictions on fish consumption, fish tumors and other deformities, beach closings, eutrophication and summer hypolimnetic dissolved oxygen depletion, interferences with drinking water, degradation of benthos, and exceedences of water and sediment quality criteria. Most of these problems can be traced directly to the presence of contaminated sediments in the harbor, The paper proposes a statistical approach to delineating sediment zones according to trace element distributions"--Introduction, page 4.
