A case study presenting the limitations and pitfalls of
performing an extensive in-situ sampling program at a
complex disposal site is evaluated compared to the actual
soil conditions encountered during site development.
Development of urban brownfields and contaminated
sites for a multitude of land uses both commercial and
residential is becoming more common place.
The rising value of urban properties and the means
to more accurately incorporate the costs of site
remediation into site development coupled with legislative
changes limiting the liabilities of financial institutions
and land developers is bound to continue the trend of
accelerated urban redevelopment of brownfields.
This case study presents the actual findings
encountered during site development compared to the design
studies, highlights pitfalls and limitations of the
in-situ pre-characterization program and offers potential
alternatives for incorporating soil management procedures
into site design.
The case study involves the construction of a
multi-use urban development incorporating retail, transit
and residential land uses on a 9 acre lot.
The property was contaminated with gasoline and MGP
wastes including MtBE, BTEX, Reactive Sulfide and toxic
metals.
