 The
subject property had formerly been utilized as an industrial manufacturing
facility built in the early 1960s. ENSAT 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 ENSAT to characterize the extent of subsurface chlorinated
hydrocarbon contamination and to monitor and direct asbestos abatement
throughout the site building (65,000 square feet). ENSAT 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
monitor 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, ENSAT recommended that our client apply for No Further
Action designation from the Maryland Voluntary Clean-up Program
(VCP) application. Additional subsurface investigation required
by the VCP was conducted by ENSAT. 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 No Further Action
Required designation again reclaiming marketability for the
property.
