Industrial Property, Chonburi, Thailand
SLP Environmental was appointed by a multinational semiconductor manufacturer to provide a package of due diligence studies associated with the acquisition of a 1 ha industrial landplot for the construction of a new manufacturing facility. SLP was awarded the contract to perform the Phase 1 and 2 Environmental Site Assessment (as per ASTM E1527- and E1903 practice respectively) as part of the business transaction due diligence process.
The Phase I ESA study comprised of desk study, site and environs reconnaissance and interviews with key informants. This facilitated the development of a preliminary conceptual site model (CSM) for the property and a determination as to whether any Recognised Environmental Conditions (REC) were associated with the Subject Property.
The Phase 2 ESA comprised of an intrusive site investigation that targeted the likely release areas identified during the Phase 1 ESA. The scope of works included the drilling of three exploratory soil bores and the recovery of soil samples throughout the soil bore profile. Once the soil bores had reached the required depth, groundwater monitoring wells were installed within the boreholes, and groundwater samples were recovered for ex-situ laboratory analysis. Field monitoring of selected parameters was also conducted in-situ.
The recovered soil and water samples were submitted to an ISO:17025 accredited testing laboratory for analysis for a range of potential contaminants of concern (PCOC) under strict chain of custody procedures. Once the testing data was received, SLP conducted a comparative assessment of the results against applicable Thai quality standards for soil and groundwater to determine the contamination status of the property.
The findings of the overall Phase 1 and 2 Environmental Site Assessment were presented in one consolidated report which included a description of the works, the findings, conclusions and recommendations. All supporting documentation such as figures, plans, engineering logs, laboratory data and photolog were provided in the report appendices.
