Contaminant migration via sediment porewater through a sub-aqueous cap over Hamilton Harbour sediments / Fernando Rosa and Todd Breedon. : En83-9/07-315E-PDF

"In the summer of 1995 Environment Canada carried out a pilot-scale sediment capping project in Hamilton Harbour. Clean sand (medium to coarse grain size) was placed over an area of bottom sediment, approximately 100 m by 100 m, to an average thickness of 35 cm. The average water depth of the capped area is 15 m and the maximum slope of the site is about 1.9°. Several factors, such as bottom currents, ship traffic and wave induced shear stress were considered in the selection of the site (Zeman 1994). Results of the pre-capping geotechnical and sedimentological testing were discussed by Zeman et al (1995) ... The objectives of this study were to assess the long-term mobility of different pore water elements through the cap material and to measure the quality and quantity of harbour sediments resettling on the cap surface"--Introd., p. 3.
