Phase I & Phase II Environmental Site Assessments - San Francisco

GeoSolve® was retained by KELLCO Services, Inc. to perform a Phase I Environmental Site Assessment on an older building within downtown San Francisco, California.  The Phase I ESA was performed in less than two weeks, and our findings indicated the building was formerly used as a glass manufacturing and paint shop in the late 1890s through the early 1900s and metals, VOC and petroleum-hydrocarbon constituents may have been present beneath the subject site.  GeoSolve® contracted with a State-licensed direct-push drilling contractor to advanced eight borings to groundwater within the building.  Soil and groundwater samples collected from the borings were submitted to a State-certified hazardous waste testing laboratory for analysis.   Laboratory analysis of the soil and groundwater samples indicated elevated concentrations of metals within the surficial soil and groundwater.  A technical report of the field and laboratory methods and results was prepared within two days of receipt of the laboratory analytical results and submitted to KELLCO Services, Inc. for review and approval.  The Phase I & Phase II ESAs were used to discourage a KELLCO Services, Inc. client from purchasing the property due to the high cost of remediation and environmental liabilities associated with the metal contamination.
