Former
Manufacturing Facility
Bethesda, Maryland
The subject property had formerly been utilized as an industrial
manufacturing facility built in the early 1960s. CGS was retained by a
perspective purchaser of the property to perform a Phase I
Environmental Site Assessment (ESA) to identify any potential
environmental concerns associated with the Site. Our Phase I ESA
recommended a limited Phase II subsurface screening of both soil and
groundwater at the Site as well as abatement of asbestos containing
materials (ACM).
Results from the limited subsurface screening indicated the presence of
elevated concentrations of chlorinated hydrocarbons or
“solvents” in groundwater at the Site. In an
attempt to
salvage the sale of the property, the owners of the Site retained CGS
to characterize the extent of subsurface chlorinated hydrocarbon
contamination and to monitor and direct asbestos abatement throughout
the site building (65,000 square feet). CGS utilized the latest methods
in environmental sampling technology to expedite the characterization
process. A soil gas survey was conducted in an attempt to select
optimum locations for soil borings and/or groundwater monitoring wells.
Soil samples were collected with a Geoprobe® drill rig that was
capable of completing numerous soil borings in a relatively short
interval of time. Groundwater monitor wells were completed at the Site
with a hollow stem auger drill rig.
Based on the findings of the
subsurface investigation conducted at the Site, CGS recommended that
our client apply for No Further Action designation from the Maryland
Voluntary Cleanup Program (VCP). CGS assisted our client with the
preparation and submittal of the VCP application. Additional subsurface
investigation required by the VCP was conducted by CGS. Upon completion
of the subsurface investigation a final report was submitted to the VCP
that included conclusions associated with potential risks and a
recommendation for site closure. The Site ultimately received a No
Further Action Required designation again reclaiming marketability for
the property. Currently the site is utilized as a domestic storage
facility.
