Across the nation, proposed clean-up actions may threaten endangered species and essential habitat upon which they rely. Determining how to implement remedial actions that meet human health and safety concerns while preserving significant natural resources is a significant policy complication and driver. Marstel-Day uses an analytical methodology called the Net Environmental Benefit Assessment or NEBA to assist in developing cleanup approaches that provide the greatest natural resource benefits while appropriately managing site risks. Marstel-Day evaluates the potential of currently available ecological and economic benefit metrics to assist such clients as the US EPA in demonstrating the ecological benefits of site cleanup in some cases, and in preserving those benefits despite cleanup in others. We assess the pre- and post- cleanup data associated with the sites to quantify the net ecosystem service benefits associated with the range of final remedies that could be selected for site restoration. Our evaluation provides a clear comparison of each selected metric’s ability to clarify ecological and economic tradeoffs associated with alternative scenarios. As a result, decision-makers and regulators are better equipped to make remedial selections that protect human health and safety, as well as environmental resources, such as wetlands and riverine ecosystems upon which many threatened and endangered species rely for their survival.
