Urban Fill Site / Former Gas Station

Metro Boston

For a major pharmaceutical firm, Mr. Young directed the MCP investigation/remediation of an urban fill and former gasoline station site in metro Boston, which was slated for redevelopment as an office building with three levels of subsurface parking.  Investigation began with a due-diligence Phase II, which identified urban fill (PAHs/lead) impacts in soil, and gasoline in soil and groundwater from an unknown source.  Two previously-unidentified 10,000-gal USTs were subsequently uncovered during construction excavation, which were the previous owner’s responsibility to remove.  Mr. Young coordinated removal of USTs by the previous owner’s consultant, and managed testing, characterization, removal, and disposal of gasoline-impacted soils and of urban fill excavated from the site to make way for construction of the sub-surface parking structure.  These remedial activities were coordinated with ongoing construction activities, with virtually no delays to the construction schedule.  The MCP investigation was closed, and the property is now in active use as offices for the firm.



  • Successfully coordinated excavation and export of contaminated materials in a tight space where stockpiling was not possible, in the midst of construction activities.
  • Soil remediation was completed without affecting construction schedule.
  • Successfully completed soil remediation while coping with limiting factors such as buried utilities, proximity of building foundations, and city streets.
  • Used site-specific risk assessment to avoid the need to remediate groundwater, or to impose a deed restriction to compensate for impacted soil.
