Figures 14.18 and 14.19, respectively, show aerial and ground-level views of the site after
demolition of the buildings.
This site did experience some synergistic effect between the moderate vulnerability
of the geologic environment and the use of high-risk chemicals. Damage was limited by
the leakage of groundwater into the storm sewers, the lack of significant groundwater
volumes, and building foundations inhibiting groundwater flow. These anthropogenic
influences prevented a larger environmental impact commensurate with the risks present.
Despite this good fortune, investigation and remedial costs were expensive—the project
lasted 12 years after conducting the Phase I ESA, with expenditures totaling $9.3 million,
The lessons learned from this case study include
• Geologic maps are essential to all remediation efforts. In areas where there is high
anthropogenic disturbance, geologic maps can help investigators distinguish
between natural and artificial drainage patterns.
