摘要

New Bedford Harbor sediments contain substantial amounts of both organic and inorganic contaminants. Leaching studies with this sediment indicate that the leachate generated from the disposal of these sediments may contain significant amounts of the same contaminants. This investigation examined the available literature and data pertaining to the chemical compatibility of synthetic and natural liners with both organic and inorganic contaminants. Although compatibility testing with various liner materials and leachate with contaminant concentrations exactly like New Bedford Harbor sediment leachate is not available, testing with contaminant mixtures similar to and with higher concentrations has indicated no significant compatibility problems. Lining experience has shown that, with low contaminant-concentration mixtures such as the leachate generated from disposal of New Bedford Harbor sediments, problems with installation may be of more concern than liner compatibility.
