Marine ecological-risk assessment pilot study for Allen Harbor, Narragansett Bay, Rhode Island. Professional paper
An ecological risk assessment framework was applied to characterize aquatic risks associated with hazardous waste disposal at Naval Construction Battalion Center (NCBC) Davisville, Rhode Island. An initial screening phase (I) assessed exposure and related that exposure to toxicological endpoints for bivalves, amphipods, sea urchins, and biomarker assays. Results showed little evidence of major contamination in sediments or tissues except for relatively high levels of polychlorinated biphenols (PBC), butyltins compounds (TBT), and fecal coliforms observed in Allen Harbor. Effects were detected in mussel physiology, sea urchin fertilization and development, biomarker responses, and soft shell clam histology. Possible sources of contamination and toxicity from the landfill leachate, surface runoff, and recreational boating were examined using a temporaland spatial sampling scheme. Chemical and toxicological information obtained implicated all three sources as affecting Allen Harbor water quality. Laboratory bioassays of landfill exposure media, employing a variety of marine species using acute and chronic endpoints, are being used to provide data for the development of an exposure-response model for risk to the marine environment. The model will define current risk and provide an interpretive framework for long-term monitoring.
