How Clean is Clean?. Edition No. 1
VDM Publishing House, Oct 2008, Pages: 256
Quantitative risk assessment is a crucial tool in
determining the degree of clean up at contaminated
sites and to answer the fundamental question -- how clean
is clean? The purpose of this study was to examine
how the U.S. Environmental Protection Agency has
relied on quantitative risk assessment in its three
site remediation programs: Superfund, the RCRA
Corrective Action Program, and the Underground
Storage Tank Corrective Action Program.
Interestingly, each of these programs were created
within a few years of each other, has the same
statutory cleanup goals, addresses some similar
contaminants, addresses the same environmental media,
uses the same toxicological data, and uses the same
default exposure assumptions. However, over time,
each program’s reliance has become quite different.
This study explores the scientific, political,
programmatic, organizational, historical, and
socio-economic factors that have influenced the
divergence.
