AUDITECO was retained by a multinational consulting and engineering company from UK to perform a Phase I ESA for a former industrial facility located in Bucharest, Romania. Following the conclusions of the Phase I ESA report, a Phase II ESA was performed by the AUDITECO consultants. The Phase I and II ESAs were developed at the request of a leading global manufacturer from the aero-spatial industry, which intended to extend its production activities on the investigated site.
The purpose of the Phase I ESA was to identify potential documented environmental issues and liabilities associated with past and current activities at the site, and to assess, on a preliminary basis, environmental ground conditions with respect to on-site and off-site historical activities which might have impacted soil and groundwater quality. An initial site visit was conducted to visually assess site conditions and current surroundings; further dataroom activities comprised a review of historical site layouts, permits and other relevant documents. All the above mentioned activities and information were integrated and evaluated in a Phase I ESA report in order to determine a potential ground contamination of the site.
Following the conclusions of the Phase I ESA report, a Phase II ESA was performed on the site. Particular challenges arising from physical site conditions were related to remaining underground structures (e.g. basements, foundations) and utilities networks (e.g. electric cables, gas pipes, water pipes and sewage) of former on-site facilities.<
The location of intrusive investigation points was proposed based on the conclusions of the Phase I ESA report. An underground locating equipment was used to scan the proposed location of each intrusive investigation at the site in order to detect the presence of underground obstructions and to mitigate risks related to proposed intrusive investigations. Twelve (12) boreholes were drilled to maximum depths of 2 m below ground level by dry percussion drilling and twelve trial pits were excavated to maximum depths of 4 m. Environmental sampling included the collection of soil gas samples (from the twelve boreholes) and the collection of soil samples at selected depths (from the twelve trial pits). VOC measurements were performed on site for trial pit soil samples. Subsequently, the chemical analyses plan was based on potential contaminants associated with former onsite and offsite activities (e.g. aliphatic hydrocarbons, heavy metals, asbestos).
Project reporting for the Phase II ESA was performed by a joint Client – Auditeco team. Our consultants’ input consisted of providing relevant Romanian screening values for the analysed contaminants, estimating surfaces and volumes of potentially contaminated areas and indicating environmental regulatory requirements for the site’s intended future industrial end-use.
