ABSTRACT:
Remedial investigations associated with the Superfund Program of the U.S. Environmental Protection Agency (EPA) found highly elevated levels of several trace elements in sediment samples from Grove Pond and Plow Shop Pond in Ayer, Massachusetts. Due to the nature and extent of contamination, federal and Massachusetts regulatory and natural resource management agencies were concerned that arsenic, cadmium, chromium, mercury, lead and other trace elements may be accumulating in the benthic community of the ponds or being transported downstream to Nonacoicus Brook and the Nashua River. The U.S. Fish and Wildlife Service was asked by EPA to conduct a limited, screeninglevel contaminant study of two benthic organisms inhabiting the ponds and brook. The purposes of the study were: - To determine arsenic, cadmium, chromium, mercury, and lead exposure in mussels and crayfish, and - To provide the U.S. Environmental Protection Agency and Massachusetts Department of Environmental Protection with site-specific data for human health and ecological risk assessments of Grove Pond and Plow Shop Pond.
