Abstract
- Many years of untreated effluent discharge from residential areas, a shipyard, marina and a large fish market resulted in substantial contamination of bottom sediment in Southern Busan Harbor, South Korea. Contaminants in these sediments include heavy metals and organic compounds. Newly introduced regulations for ocean disposal of dredged material in S. Korea pose significant challenges because the previous practice of offshore disposal of contaminated dredged material will no longer be possible after 2008.The S. Korean government has mandated that such sediments be assessed in a way that identifies the most appropriate dredged material management alternative addressing environmental, social, and cost objectives. An approach using multi-criteria decision analysis in combination with comparative risk assessment was used as a systematic and transparent framework for prioritizing several dredged sediment management alternatives. We illustrate how multi-criteria decision analysis can recognize the multiple goals of contaminated sediment management. Values used in weighting decision criteria were derived from surveys of stakeholders consisting of sediment management professionals,business owners, and government decision makers. The results of the analysis showed that land reclamation was the preferred alternative because it performed well across all criteria investigated. The implementation of this alternative will require the construction and use of a near shore confined disposal facility within a reasonable distance from dredging area.
