Organochlorine pesticide residues in inactive cranberry bogs of the Edwin B. Forsythe National Wildlife Refuge

Metadata Updated: December 11, 2017

A 1996 Baseline Contaminants Investigation of the U.S. Fish & Wildlife Service’s (Service) Edwin B. Forsythe National Wildlife Refuge (EBFNWR) revealed elevated sediment organochlorine pesticide residues down-gradient of abandoned cranberry bogs on Four-mile Branch and Ballinger Creek (USFWS 1998). The purpose of this investigation was to determine if the abandoned bogs, now under U.S. Fish & Wildlife Service (Service) ownership, were a potential source of pesticide residues. Sediment samples were collected from within two bogs on the Oxycocus Property in Stafford Township, Ocean County, New Jersey, for organochlorine analysis. The results of that analysis indicate that the abandoned cranberry bogs sediments contain organochlorine pesticide residues, especially DDT and related breakdown analogs, DDD and DDE. The high organochlorine pesticide concentrations correlate with severe adverse impacts to benthic macroinvertebrates. In response to initial sediment results from this study, the Service initiated a Cleanup Project in 2003 to further address and eliminate bog sediments as a source of down-gradient contamination, and to develop a hydrodynamic model of bog effluent flow, which could transport re-suspended bog sediments during high flow events. Further work under the Cleanup Study is being undertaken to address fish contamination from organochlorine pesticides associated with the Oxycocus Property bogs to address ecological and human health risks in downstream Manahawkin Lake. There are similar needs that are currently unmet at other bog related locations.
