It is generally agreed that both the landfill option, or the civil techniques option for the final disposal of contaminated harbour sludge involves the isolation of the sludge from the environment. For short time scales, engineered barriers such as a bentonite screen, plastic sheets, pumping strategies etc. can be used. However for long time scales the effectiveness of such measures cannot be counted upon. It is thus necessary to be able to predict the long term environmenttal spread of contaminants from a mature landfill. A model is presented that considers diffusion and adsorption in the landfill site and convection and adsorption in the underlaying aquifer. From a parameter analysis starting form practical values it is shown that the adsorption behaviour and the molecular diffusion coefficient of the sludge, are the key parameters involved in the near field. The dilution effects of the far field migration patterns are also illustrated.

To support the choice of a remediation technique for the decontamination of PAH contaminated dredged sediments a characterisation test is needed, that takes into account the physical state in which PAHs occur. Here, solvent extraction is proposed as such a characterisation test. Solvent extraction experiments were performed with a 1/1 acetone-water mixture on (particle size fractions of) PAH-contaminated harbour sludge. The PAHs were more easily dissolved from fine than from coarse fractions, which indicates that the PAHs in the fine fractions are better (bio)available. The results further suggest that PAHs were present in particulate form, absorbed in organic matter and dissolved in oil. The performed extraction experiments provide a basis for further development of existing models.

The Clyde Sea Area is in many ways an ideal ground for the investigation of the nutrient salts in the bottom deposits. The different lochs present a range of depth of water of from 0 to 200 metres: some parts have strong tidal currents up to five knots, while others are practically unaffected by the tide: some lochs have also been affected by the dumping of sewage and harbour sludge, and the effect of these can be examined. Conditions may also be compared in muds ranging from the loch heads to the almost open sea conditions at Ailsa Craig.
