Abstract
This article discusses a framework and tools for evaluating ecological resources and the effects of cleanup on hazardous waste sites, particularly those with ecological buffer lands. Environmental professionals are faced with assessing the risks of contamination to humans and ecological receptors (organisms and ecosystems) at hazardous waste sites. While exposure assessment has focused largely on human receptors, environmental managers have recently taken a broader view, recognizing the intrinsic value and aesthetic importance of ecological resources and services, and of including a range of stakeholders in remediation decisions. The assessment process involves understanding exposure pathways from source to receptor, and determining how best to interdict these pathways. Environmental characterization and exposure assessment, indicator and biomarker identification, and biomonitoring and surveillance are the major components of ecological assessments. Using the Department of Energy as a case study, this article offers a framework for ecological exposure assessment, recognizing that humans are important components of ecosystems and, like other biota, are exposed to contaminants that move through environmental media.
