With projections for remediating contaminated sediments in the U.S. running into the trillions of dollars, alternative risk assessments can ensure more efficient use of public and private funds while reducing the need for expensive and potentially damaging large-scale remediation projects. In this paper, Haley & Aldrich’s Russell Schuck and Steve Clough examine one often-overlooked alternative—bioavailability—which determines the actual fraction of a contaminant absorbed by an organism. By taking into account real-world health consequences that standard chemical analyses do not, bioavailability can substantially reduce project scope and costs for responsible parties.
